Cables

The OnePack weighs 120 lbs. Team lifting is recommended when installing the battery.

BATTERY INSTALLATION

The Lithium-ion battery voltage must be matched to the vehicle where it is installed.
DO NOT CONNECT BATTERIES IN A SERIES OR PARALLEL. SERIES & PARALLEL CONNECTION MAY POSE DANGER TO USER AND/OR INSTALLER AND CAUSE DAMAGE TO THE BATTERY.

4.1 INSPECTION AND 12V ACCESSORIES
Check for visible damage including cracks, dents, deformation and other visible abnormalities. The top of the battery and terminal connections should be clean, free of dirt and corrosion, and dry. If any problems are detected with the battery, contact Trojan technical support or your battery distributor. If damage occurred in transit, contact your freight carrier. To prevent damage to 12V accessories in the vehicle, first verify the voltage requirement of accessories like lights or other items in the vehicle. Never connect vehicle accessories directly to the battery. Battery accessories such as Dashboard SOC Gauge Kit (10001373) shall be directly connected to the battery as indicated in Section 4: “Battery Installation. Lithium-ion batteries are more susceptible to permanent damage from parasitic loads than other battery types. If a continuous load such as a light, USB charger, voltage reducer, GPS or battery state of charge indicator is left connected to the battery for an extended period of time, a low voltage fault will occur. If left in this condition, the battery could become unrecoverable. All vehicle accessories should be wired through the vehicle key switch or another method of disconnecting the equipment from the battery when not in use. Then, if needed, the installer can use a voltage reducer to reduce the battery voltage to 12V or as required. To ensure you install your battery properly and safely, please use the following guidelines.
4.2 TERMINALS AND TORQUE VALUES
Both the positive and negative terminals of the battery are M8-1.25 female threads. Ensure the hardware is tightened to the proper dry torque of 50-60 in-lbs (5.6-6.8 Nm). OVER-TIGHTENING TERMINAL CONNECTIONS CAN CAUSE TERMINAL BREAKAGE, AND LOOSE CONNECTIONS CAN RESULT IN TERMINAL MELTDOWN OR FIRE.
4.3 CORRECT HARDWARE INSTALLATION
If using flat or lock washers, it is very important to ensure the battery cable lug is contacting the top surface of the terminal, and the washer is placed on top of the lug. DO NOT PLACE A WASHER BETWEEN THE BATTERY TERMINAL AND THE LUG, AS THIS WILL CREATE HIGH RESISTANCE AND CAUSE EXCESSIVE HEATING OF THE CONNECTION, WHICH CAN RESULT IN FIRE. If assistance is needed in determining the appropriate hardware configuration, contact Trojan Battery technical support.
4.4 CABLE SIZE
Battery cables should be sized to handle the expected load and be of sufficient length and flexibility to avoid applying undesirable mechanical loads on the battery terminals. Refer to Table 1 for the maximum amperage based on the cable/ wire gauge size.

WARNING! SHOCK HAZARD – DO NOT TOUCH UN-INSULATED BATTERY, CABLES, OR TERMINALS. ALL TOOLS SHOULD BE ADEQUATELY INSULATED TO AVOID THE POSSIBILITY OF SHORTING CONNECTIONS. DO NOT LAY TOOLS ON THE TOP OF THE BATTERY.

TABLE 1
Table values are from NEC Table 310.15(B)16 for copper cables rated at 167°F (75°C), operating at an ambient temperature of no more than 86°F (30°C). Lengths in excess of 6 feet (1829mm) may require heavier gauge wire to avoid unacceptable voltage drop. In parallel battery banks, it is preferable for all cables to be the same length.
For more information refer to the National Electrical Code for correct cable/wire size, which can be located at www.nfpa.org

4.5 VENTILATION
Trojan® Lithium-Ion batteries do not release gas during normal use. There are no specific ventilation requirements for Trojan Lithium-Ion Battery installations, although sufficient airflow should be provided to prevent excessive heat build-up.
4.6 BATTERY ENVIRONMENT
Battery should be stored and installed in a clean, cool and dry place, keeping water, oil and dirt away from the battery.
If any of these materials are allowed to accumulate on the battery, tracking and current leakage can occur, resulting in
self-discharge and possible short-circuits. Battery chargers should also be installed in well-ventilated, clean areas that
are easily accessible. Relative humidity should be <90% and non-condensing.
4.7 TEMPERATURE
The operating temperature range for discharging the Trojan OnePack Lithium-Ion battery is -4°F to 140°F (-20°C to 60°C). Charging the battery below 32°F (0°C) is prohibited, and charging currents must be reduced below 68°F (20°C) and above 113°F (45°C) . Attempting to charge the battery at temperatures below 32ºF (0ºC) will cause the battery to disconnect from the charger and enter an under-temperature alarm, charging will be disabled while the alarm is active.
Refer to Section 10.1: “Charging” for charging current limitations.
Note that battery life diminishes as temperature increases. Useable capacity diminishes as battery temperature decreases.
4.8 BATTERY START-UP
Your battery may be shipped at 50% state of charge (SOC) or lower. Prior to installation, fully charge the battery to 100% SOC.
Prior to installation, follow the instructions in Section 6.2: “Initial Charging.”
Perform the following steps to turn the battery on:

Verify that the battery is either completely disconnected or correctly connected to the equipment it will be powering.
Be sure you are able to see the ON/OFF Power Switch on the side of the battery.
Press and hold the ON/OFF Power Switch for 6 seconds then release. The Green LED will have 4 long blinks to indicate the button can be released.
 A green blinking LED light will appear on the ON/OFF Power Switch to indicate the battery is on.
Perform the following steps to turn the battery off and place it in storage mode:
Press and hold the On/Off switch for 6 seconds then release. The green LED will have 4 long blinks to indicate the button can be released.
 The green blinking LED switch light will no longer be illuminated. The battery is off if no illumination is present.

Power On/Off: Locate the ON/OFF Power Switch on the side of the battery in-between the power terminals. Turning On: Press the button, hold for 6 seconds, and release. A green blinking LED light will appear to indicate the battery is on. Turning Off: Press the button, hold for 6 seconds, and release. Verify that the green LED is no longer blinking.

The battery can also be turned on and off using the dashboard push button accessory. If using the dashboard push button to turn the battery on or off, push and hold the button for 1 second. The SOC gauge display will be your indicator if the battery is on or off.
If the battery has been intentionally turned off for shipping or because of a shutoff condition, you can restart it by the above steps. However, if a condition that causes a shutoff has not been corrected, the battery will shut off again.
See Section 10.3: “Protection Limits: Automatic Disconnection,” for specific explanations of shutdown causes.

4.9 ON/OFF PUSHBUTTON INDICATOR LED LIGHT
The Trojan® OnePack Lithium-Ion battery features a ON/OFF Power Switch with a green ring LED indicator. Below are the following steps to understand your battery’s ON/OFF Power Switch functions:

LED BLINK PATTERN| STATUS| DEFINITION| LED BLINK PERIODICITY
---|---|---|---
1 short green LED blink| Battery Active| Indicates the battery is ‘active’| Repeats once every 4 sec
1 long green LED blink| Battery Fault| Indicates the battery has a ‘fault’| Repeats once every 3 sec
2 short green LED blinks| CAN Communication| Indicates the CAN communication is active| Repeats once every 1 sec
NO LED blinks| Battery Asleep| Indicates the battery is in storage mode| NA

4.10 CAN BUS
The battery includes a Controller Area Network (CAN) bus communications interface. The two circular M8 DIN connectors are on the side of the battery to enable communication with the battery and support battery accessories such as the Dashboard SOC Gauge Kit (10001373). For normal battery operation, the CAN bus feature is not required. The battery operates and protects autonomously; it does not require any CAN bus communication or external devices such as external controllers. Keep the two black caps installed on the two M8 connectors to protect them from the environment when not used. Trojan’s field service can retrieve the battery usage history and view status over the CAN bus interface to help resolve issues or questions. A certified field service technician can update the battery firmware over the CAN bus as needed. The CAN bus interface is galvanically isolated from the internal battery voltages. Therefore, an external power source is required to turn on and power the field side of the isolated CAN bus. Contact Trojan’s technical support engineers if you have any questions about the CAN bus interface and its use.
See Section 8: “Maximizing the Performance of Your Battery” for technical support information.

PREVENTATIVE MAINTENANCE

5.1 INSPECTION
Power off battery before inspection.
Examine the outside appearance of the battery. The top of the battery, sides, and terminal connections should be clean, dry and free of corrosion.
Check battery cables and connections. Replace any damaged cables and tighten any loose connections.
Refer to Section 4.2: “Terminals and Torque Values.”
 Verify mounting brackets are still securely mounted to both the battery and the vehicle.

5.2 CLEANING
Check the battery for cleanliness at regular intervals and keep terminals and connectors free of corrosion.
Terminal corrosion may adversely affect the performance of the battery and present a safety hazard.
Power off battery before cleaning.
Disconnect the battery from the charging source and the load.
Clean the top of battery, sides, and terminals with a damp cloth or non- metallic brush. If the battery is extremely soiled, a household cleaner may be used.
Dry with a clean cloth.
 Keep the area around batteries clean and dry.

Charging

6.1 BACK GROUND
The Trojan OnePack Lithium battery may be used in applications where lead-acid batteries have previously been utilized. Best charging results are obtained by using an appropriate Trojan-recommended charger and charging profile (algorithm). Refer to documentation on your specific charger for more information. Charging due to regenerative braking should also be reduced in environments below 68°F or above 113°F. Vehicles that use regenerative braking at cold temperatures may force the battery to shut off if too much current is applied back into the battery.
6.2 INITIAL CHARGING & CHARGING PROFILES
Unless your dealer has charged your battery prior to delivery, it will be received at partial state of charge. Prior to installation, fully charge the battery to 100% SOC.
The Trojan OnePack Lithium battery should be charged using a lithium-ion charging profile with a voltage setting between 54.7V – 56.0V. Use of a compatible charging profile is required to obtain a fully balanced battery pack. Using charging profiles designed for lead-acid or other battery types may result in a sudden voltage increase that will cause permanent damage to the battery BMS and render the battery inoperative. For a list of compatible chargers and charging profiles, visit www.trojanbattery.com.
Batteries regularly charged with equipment not optimized for lithium-ion batteries may become imbalanced and is not recommended. See Section 6.4: “Balancing” for additional information.

Use Only With Compatible Lithium-lon Chargers Scan For the Approved List

6.3 CHARGING PROCEDURES
Verify that the battery is correctly hooked up to the charger with the positive wire on the positive (+) terminal and the negative wire on the negative (–) terminal.
Ensure the charger is set to run the appropriate profile.
If the charger will not run until it detects battery voltage, be sure that the batteries are turned on.
Start charging, following the charger manufacturer’s instructions.
After the charge has completed, the charger may be shut off and disconnected, or if it remains in a “maintenance mode” within the recommended charging range, it can remain connected to the battery indefinitely.
6.4 BALANCING
One function of a lithium-ion battery BMS is to maintain balance between each group of cells within the battery.
This allows the battery to deliver full capacity without any cells experiencing an over or under-voltage condition.
Balancing is performed when a parallel group of cells reach a specified threshold voltage corresponding to nearly 100% state of charge (SOC). At that point, the highest-charged cells “bleed down” a small amount to enable the remaining groups of cells to “catch up.” Balancing may cause small changes in state of charge up to 2%.
Using a charger not designed for use with a lithium-ion battery may result in an imbalance between cells over time that requires charging maintenance to recover. Recovery of an imbalance condition requires one or more charging cycles to 100% state of charge using a lithium-ion specific charger or charging algorithm. Failure to do so may result in a battery lockout condition.
6.5 CHARGING AT TEMPERATURES BELOW 68°F (20°C)
Maximum charging currents must be reduced at temperatures below 68°F (20°C). Measures need to be taken to ensure that charging currents do not exceed the values shown on the product datasheet. As mentioned previously, charging is prohibited below 32°F (0°C). Charging due to regenerative braking should also be reduced in environments below 68ºF. Vehicles that use regenerative braking at cold temperatures may force the battery to shut off if too much current is applied back into the battery.
6.6 CHARGING AT TEMPERATURES ABOVE 113°F (45°C)
Maximum charging currents must be reduced at temperatures above 131°F (45°C). Measures need to be taken to ensure that charging currents do not exceed the values shown on the product datasheet. As mentioned previously, charging is prohibited above 131°F (55°C). Charging due to regenerative braking should also be reduced in environments above 113ºF. Vehicles that use regenerative braking at hot temperatures may force the battery to shut off if too much current is applied back into the battery.
6.7 CHARGING FROM 0% STATE OF CHARGE
If the battery is discharged to 0% state of charge, voltage to the battery terminals will be disabled and the battery will enter into storage mode. The battery should be recharged as soon as possible. Failure to do so may render the battery permanently unusable.
A battery at 0% state of charge may interfere with the operation of battery chargers with voltage-sensing protection and prevent the charge cycle from starting. If the battery is at 0% state of charge and will not charge, use the following steps to recover the battery:

Plug in the charger and connect it to the battery.
Power on the battery using the ON/OFF Power Switch following the procedure in Section 4.8: “Battery Start-Up.”
Note that the battery will not turn on using the dashboard push button accessory.
The battery will remain powered on for 5 minutes to allow for the charging cycle to begin. If it does not begin, verify power to the charger and the connection to the battery and repeat this process.
 Depending on the battery voltage, it may be necessary to repeat these steps until regular charging resumes.

6.8 OTHER CHARGING INFORMATION
Chargers which utilize an automatic desulfation or equalization mode are not recommended.
Depending upon the initial state of charge and the size of the load, even small quiescent loads such as motor controllers and on-board chargers can fully discharge batteries in as little as a few days. For instance, a 25mA load amounts to 0.6Ah discharge per day. Be sure to understand the quiescent loads in your application and set an appropriate charging interval. If the batteries will not be used for extended periods of time, turn them off.
It is not recommended to use power outlets controlled by switches, peak shaving controllers or that rely solely on non-continuous power sources such as solar or wind generation to charge batteries. Interruption of the charge cycle may prevent the battery from reaching full state of charge or prolong charging times.

STORAGE AND SHIPPING

A fully charged OnePack can be safely stored in climate-controlled conditions for up to one year (12 months) while in storage mode. It is recommended that the battery state of charge is checked every 4-6 months. Temperatures exceeding 77ºF (25ºC) will cause
the battery to self-discharge faster and will require more frequent checks.
The following tips will help ensure that your batteries emerge from storage in good condition:
Never put the battery into prolonged storage if the state of charge is below 30%.
Prior to long-term storage of the battery, fully charge the battery. Storing a discharged battery can result in permanent damage or decreased run time.
Store in a cool and dry location, protected from the elements.
 Place the battery in storage mode to eliminate potential parasitic loads that may discharge the battery.
When batteries are taken out of storage, they should be given an initial charge prior to use as outlined in Section 6: “Charging.”

IF YOU SHIP THIS BATTERY, YOU MUST COMPLY WITH STATE, FEDERAL AND INTERNATIONAL LAWS, RULES, REGULATIONS AND REQUIREMENTS REGARDING LITHIUM BATTERIES. YOU MUST UTILIZE A QUALIFIED SHIPPING AGENT PROPERLY CERTIFIED FOR HAZARDOUS MATERIALS (“HAZMAT”) SHIPMENTS.

MAXIMIZING THE PERFORMANCE OF YOUR BATTERY

Follow all the procedures in this User’s Guide for proper installation, maintenance and storage.
If you have any questions or concerns about battery care, please contact Trojan’s technical support engineers at 800-423-6569 Ext. 3045 or +1-562-236-3045 before a problem develops.

WHAT TO EXPECT FROM YOUR TROJAN LITHIUM-ION BATTERY

Your Trojan OnePack Lithium-Ion battery will deliver rated capacity when it is new. No “break-in” period is required.
When operating batteries at low temperatures, they will deliver less than the rated capacity.
When operating batteries at high temperatures, battery life will be reduced.
 The life of a battery is difficult to predict and will vary by application, frequency of usage and load characteristics.
9.1 QUIESCENT LOADS
Some vehicles, especially those with voltage reducers, radios and GPS units installed will continue to drain a small amount of power from the battery, even with the key switch in the Off position or the vehicle placed in Tow Mode. This is called a quiescent load and can consume 5-10% of the battery’s capacity per day even when not in use. Quiescent loads will vary from vehicle to vehicle.
To limit these types of loads, it is important that all vehicle accessories are wired through a switched power source that is disconnected with the vehicle’s key-switch. Note that the battery accessories (SOC gauge & dashboard pushbutton) will not be wired through the vehicle’s key switch. See Section 4: “Battery Installation” for further information.
For installations with a quiescent load, it is recommended that the battery is disconnected from the vehicle or placed into storage mode before extended periods of inactivity. This can be done by using the ON/OFF Power Switch on the side of the battery or the dashboard push button accessory. To prevent over discharge, the Trojan OnePack Lithium-Ion battery uses an automatic sleep feature that puts the battery into storage mode after 4 hours of inactivity. If the battery capacity drops below 25% SOC while inactive, it will enter into storage mode after 1 hour of inactivity. To wake the battery from storage mode, use the ON/OFF Power Switch on the side of the battery or the dashboard push button accessory.
See Section 4.8: “Battery Startup” for additional information..
