The Essential Lithium-Ion G24 batteries are equiped with an integrated button and LEDs to assist with turning battery on/off, SOC determination, fault/error handling, and status reference. Below is a description of the various button and LED functions.

3.1 TURNING ON

To turn on battery, press and hold the power button located on the top of the battery for 5 seconds. LEDs will light up indicating the state of charge (SOC) and battery status.

When the battery is on and there are no faults/errors, the battery is in “RUN” mode. This mode is identified by the illumination of the “RUN” LED. In this mode, the battery is ready to be used and voltage is present at the terminals.

3.2 TURNING OFF

To turn it off, press and hold the button for approximately 5 seconds. Once off, the RUN LED should no longer be illuminated.

Batteries should be turned off while in storage to prevent an over-discharged condition. Batteries should not be stored for more than 6 months without charging and never stored in a fully discharged state.

Batteries will enter a sleep mode after 24 Hours of inactivity.

3.3 FAULT TROUBLESHOOTING

UNDER VOLTAGE
Battery has been over discharged. The batteries need to be charged immediately.
OVER CHARGE CURRENT
Charge current is greater than the maximum allowed. Verify charger is designed for Lithium Ion and that the algorithm is also set for Lithium Ion.
OVER DISCHARGE CURRENT OVER DISCHARGE CURRENT
Discharge load is greater than the maximum allowed. Verify that the battery pack is sufficiently sized for the application. Installing an additional battery in parallel may be required in order to decrease the discharge load across each battery below the maximum allowed.
SHORT CIRCUIT
Stop operation immediately. Short circuit protection is activated when when the discharge current exceeds the short circuit limit in Table 6. This is a dangerous scenario and should be handled with extreme caution. Verify that all connections are secure and free of obstructions. Verify that batteries are clean of all debris. If fault occurs again, have a professional evaluate the electrical system.
CHARGE OVER TEMP
Battery internal temperature has surpassed the maximum. The battery must be allowed to cool. The wait time is dependent on the ambient temperature and battery box design. Battery cables can come loose and cause a significant rise in temperature. Check that all battery cables are secure. If multiple batteries are in parallel, make sure that there is at least a 1 inch gap surrounding the battery.
CHARGE UNDER TEMP
Battery Internal temperature has surpassed the minimum. Battery temperature must be allowed to increase before usage. Do not heat the battery using external devices such as heat guns, ovens, etc. To prevent future “under Temp” errors store the batteries or vehicle inside a temperature controlled environment.
DISCHARGE OVER TEMP
Battery internal temperature has surpassed the maximum. The battery must be allowed to cool. The wait time is dependent on the ambient temperature and battery box design. Battery cables can come loose and cause a significant rise in temperature. Check that all battery cables are secure. If multiple batteries are in parallel, make sure that there is at least a 1 inch gap surrounding the battery.
DISCHARGE UNDER TEMP
Battery Internal temperature has surpassed the minimum. Battery temperature must be allowed to increase before usage. Do not heat the battery using external devices such as heat guns, ovens, etc. To prevent future “under Temp” errors store the batteries or vehicle inside a temperature controlled environment.

4 INSTALLATION

4.1 CABLE SIZE AND BOLT/NUT SPECIFICATION

Cable Size with Max Ampacity Table
Cable size has a direct influence on the voltage drop across the system. The following are guidelines. A trained professional should verify that your system is correctly sized and installed. Cables must be sized according to the expected load using “Table 5”.

TABLE 5

Table values are from NEC table 321.15(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 series/parallel banks, it is preferable for all series cables to be the same length, and all parallel cables to be the same length. Refer to the national Electrical Code for correct wire sizing which can be located at http://www.nfpa.org/.

4.2 TERMINAL PROTECTION AND INSTALLATION

During installation and handling, ensure that terminals are covered with supplied terminal protectors and only remove when ready to attach cables. It is recommended that cables be installed while the battery is turned off. See “3 Battery Operation” for instructions on turning batteries on/off.

4.3 BATTERY ORIENTATION

Lithium-Ion batteries can be oriented in any direction except upside down.

4.4 PARALLEL BATTERY CONNECTIONS

Lithium-Ion batteries should never be charged in series connection. However, in special circumstances they can be connected in series. Parallel connections are recommended. You can increase the capacity by creating a parallel connection as shown in “Diagram 3”.

DIAGRAM 3

800-695-0945-Lithium-Ion-Batteries-7.png" alt="U S Battery 1-800-695-0945 Lithium Ion Batteries 7" width="304" height="262" />

Example

PARALLEL CONNECTION
To increase capacity without increasing voltage
Two US 12VG24, rated at 100AH each connected in parallel
Nominal System Voltage: 12.8V
System Capacity: 200AH

! When using multiple batteries in parallel, it is extremely important that batteries are at the same state of charge (SOC) when installed.

Never install multiple batteries in parallel without first checking the SOC. The best way to ensure batteries are matched is by fully charging each battery prior to installation in parallel. Another way would be to ensure voltages are within 0.5V of one another prior to installation. Always install the batteries in the “Off” state by following “3 Battery Operation”.

4.5 ACCESSORIES

Never connect accessories directly to the batteries. 12V accessories should be tied into the key switch of the vehicle. Accessories should be installed in a way that they do not drain the batteries while not in use. Please consult your U.S. Battery dealer when installing accessories on vehicles using lithium-ion batteries.

4.6 BATTERY ENVIRONMENT

• Ventilation
  Lithium-Ion batteries do not need ventilation during charging. In rare and adverse scenarios, a lithium-ion battery may vent momentarily to release pressure from a cell release. If this occurs, please discontinue use (charging or discharging) of the battery and contact U.S. Battery technical support.

• Environment
  Batteries should always be installed or stored in a clean, cool, and dry place. Keep water, oil, and dirt away from the batteries. If these materials are allowed to accumulate on the batteries, current leakage can occur resulting in self-discharge and possible short-circuits. For the same reason, relative humidity should be kept below 90%.

• Temperature
  The recommended operating temperature range for US Battery lithium-ion batteries is listed in “Table 1” on page 6. Temperature plays a major role in battery usage. Hot batteries will deliver more capacity, but with diminished cycle life. Cold batteries deliver less capacity and are harder to charge. Temperature variations between cells can also have a negative effect on battery capacity and life. Temperature impact on performance is demonstrated below:

5 ELECTRICAL SPECIFICATIONS

5.1 DISCHARGE SPECIFICATION

Lithium-Ion batteries have a relatively “flat” discharge curve when compared to lead-acid batteries. In other words, the voltage stays level for most of the discharge until the very end. Therefore, estimating the state of charge (SOC) using voltage is unreliable. Many electric vehicles designed for lead- acid batteries have SOC displays that rely on voltage and as such these displays will no longer be accurate when used with lithium-ion batteries. The only way to determine SOC is by viewing the LEDs on the battery or with the Essential Li® Mobile App.

5.2 BMS PROTECTION CRITERIA

The battery management system is designed to disconnect the battery cells from the terminals to protect the battery from damage in adverse conditions. Note that this may cause vehicles to lose power, resulting in loss of control. Do not operate batteries outside of the specifications listed below. Below is a list of the conditions under which the BMS will disconnect:

6 CHARGING

6.1 BEFORE CHARGING

Proper charging is critical to maximize battery performance and life. Both under- and over-charging batteries can significantly reduce the life of the battery and cause a safety hazard. For proper charging, refer to the instructions that came with your equipment. Most chargers are automatic and pre-programmed. Some chargers allow the user to set the voltage and current values.

6.2 CHARGING

It is important to only use chargers programmed within the recommended voltage and current specifications. Use of improper chargers can result in loss of warranty. Contact the charger manufacturer for information on available battery chemistry profiles.

Check your chargers current output (A) and voltage (V) settings. If an AGM or Lithium Iron Phosphate (LFP) setting is available, choose these settings as long as they are within the specified ranges below. Many AGM profiles are within the specified ranges, but it is always best to contact the charger manufacturer about each profile’s settings before setting up. Again, it is best to have a trained professional install and set-up the charging system.

CHART 3

800-695-0945-Lithium-Ion-Batteries-10.png" alt="U S Battery 1-800-695-0945 Lithium Ion Batteries 10" width="553" height="388" srcset="https://manuals.plus/wp- content/uploads/2024/08/U-S-Battery-1-800-695-0945-Lithium-Ion-Batteries-10.png 553w, https://manuals.plus/wp- content/uploads/2024/08/U-S-Battery-1-800-695-0945-Lithium-Ion-Batteries-10-550x386.png 550w" sizes="(max-width: 553px) 100vw, 553px" />

• **MAXIMUM CHARGING CURRENT*** : 100A (PER BATTERY)
• Note that repeated high current charging periods can impact cycle life and/or warranty. Stay within the recommended charging currents below to achieve the expected cycle life. The maximum value is intended to allow occasional or short term, fast charging periods.
• **RECOMMENDED CHARGING CURRENT** : 10A – 50A
  Or less. Also known as “Bulk Current”
• **RECOMMENDED CHARGING VOLTAGE** : 14.2V – 14.6V
  Also known as “Absorption Voltage”
• END OF DISCHARGE VOLTAGE: 11.2V
• FLOAT/TRICKLE/MAINTAIN CHARGE: Not recommended
• *NORMAL OPERATING TEMPERATURE RANGE:* 0 – 50°C (32 – 122°F)
  Cannot be charged outside this range.

6.3 CELL BALANCING

Lithium-Ion battery packs contain multiple cells in series and/or parallel arrangements. Due to inherent variations in cell manufacturing processes, no two cells are identical. As a result, during charging and discharging, cells become “unbalanced” meaning they are not at equivalent states of charge. If not properly managed, this can cause premature failure of the battery pack. To address this the battery management system (BMS) “balances” cells by discharging the cells that are at a higher state of charge. This brings these cells in closer alignment with other cells in the pack.

For this to occur properly, it is very important proper charging procedures are followed. Cell balancing occurs at the end of charge and as a result this is the most critical charging period.

6.4 CHARGING FAQS

The following is a list of common questions and concerns regarding system setup, battery charging procedures. Please refer to these as general guidelines. For further assistance with your specific system setup, please contact your Installer.

CAN I USE MY EXISTING LEAD-ACID CHARGER?

• This answer depends on the specific charger as some chargers contain multiple settings. If the charger can be re-programmed or the settings can be changed to accommodate “lithium iron phosphate” cells, then yes. Some AGM battery profiles are compatible if they contain the voltage settings shown in the previous section. However, wet cell lead-acid charging profiles or settings are not compatible. Contact the charger manufacturer or authorized U.S. Battery distributor for information on how to determine if your charger can be re-programmed.

HOW LONG DOES A CHARGE CYCLE TAKE?

• There are several factors that impact charge time: charger output power (wattage), number of parallel batteries in pack, and state of charge of pack when charging starts. But as a general idea, a 20A charger can charge a 12V 100Ah battery pack from 0 to 100% in about 5 hours.

DO THE BATTERIES GAS OR NEED VENTILATION?

• Lithium-ion batteries under normal operating conditions do not “gas”. The only ventilation required would be for cooling the batteries if charging in high temperature climates.

WHAT TEMPERATURES CAN I SAFELY CHARGE AT?

• The charging temperature range of the cells is 0-50ºC (32 -122ºF)

CAN YOU “EQUALIZE” LITHIUM-ION BATTERIES?

• No, equalization charging is specific to lead-acid batteries and may result in battery fault conditions.

7 MOBILE APP

The US12VG24 battery communicates via wireless mobile applications available on most major smartphones. To download the app, scan or click the correct QR code for your device, or search “Essential Li” in your application store.

Apple Phones                  Android Phones

Each battery has an ID on the top of the battery that will correspond to an available connection on the app. If battery cannot be found, ensure that battery is on and that the application is up to date.

8 STORAGE

For long term storage (more than a month) batteries should be stored, fully charged, and turned off. You can turn the batteries off by following the directions in “3 Battery operation”. This will ensure low self-discharge rate and allow storage of up to one year.

Batteries will automatically enter a “sleep” mode after 24 hours of inactivity. Once sleep mode is entered, any charge or discharge operations will activate the batteries.

Beware of and isolate any electronics that may consume power even with the key switch off such as DC-DC converters, stereos, lights etc.

11.2 CHARGER OPTIMIZATION/DIAGNOSIS

Improper charging is one of the most common reasons for reduced operating time and overall poor performance of lithium-ion batteries. While many blame the batteries, the problem can also result from a poorly performing charging system. Keep in mind that battery chargers have various settings that can significantly alter the functionality of the charger. It is important to ensure that the settings match the recommendations listed in section 6 of this manual otherwise battery faults can occur.

Most charger manufacturers provide programmable chargers with selectable charge algorithms designed for each battery manufacturer’s products. Using the battery manu¬facturer’s recommended charging procedure will optimize battery performance and life of your battery pack. Several cycles of charging and discharging with the new charger may be required to return the battery pack to peak performance.

IT IS VERY IMPORTANT THAT CHARGERS BE PROGRAMMED FOR LITHIUM IRON PHOSPHATE CHEMISTRY.

11.3 DISCHARGE TESTING

• Start with a fully charged battery
• Ensure that all charging sources and loads are disconnected from the battery.
• Connect and start the discharger at the desired discharge rate.
• Record the runtime when the discharger is finished.
• The runtime must be corrected for temperature since the ratings that will be used for comparison were determined at 80F. Temperatures above and below 80F will affect the overall runtime.
• Temperature Compensation
• If the corrected discharge time is greater than 70% of the rated capacity at that rate then the pack is still usable.

11.4 C-RATES

C-rate is a measure of the rate at which a battery is charged or discharged relative to its capacity. For example, a 1C discharge or charge rate on a 100 Ampere hour battery would be a 100 Amps. For the same battery a 0.5C rate would be 50 Amps.

Unlike lead-acid batteries, lithium-ion battery capacity does not significantly depend upon discharge rate or “C-rate”. With lead-acid batteries, the higher the current draw, the lower the available capacity. With lithium-ion batteries, the capacity (Ah) is constant across multiple discharge rates.
