What Do I Need for Installation?
If you already have your system set up and are ready to drop in your batteries, you will need a torque wrench that can fit to and properly torque your 5/16” finishing hardware. This is REQUIRED to make sure that you torque to the specification of 9 to 11 ft-lbs., otherwise, you may cause system failures and damage.

Connecting Load-Specified Cables to the Batteries

1. Identify the positive and negative terminals. These are labeled and color-coded red for positive (+), and black for negative (–).

2. Determine which finishing hardware set you will use. Verify that your bolt can fully sit into the nylon insert of the nut. If multiple lugs are used, longer bolts may be required for the bolt to fully seat into the nylok insert of the nut.

3. Connect your cable lugs to your battery terminal with the previously identified finishing hardware set. Make sure to connect your positive load-specified cable lug to the positive terminal and the negative load specified cable lug to the negative terminal. The proper order to connect to your terminal with a finishing kit is shown in Fig. 1.
   Figure 1: Proper order of hardware to connect cables. When going from left to right in the diagram the correct order is: bolt, washer, lug, terminal, washer, and nut. If multiple lugs are used, they should be on the same side of the terminal.

4. When connecting to your battery terminals, DO NOT finger tighten. Use a torque wrench to torque your hardware to the specification of 9 to 11 ft-lbs. Failure to adequately secure connections can result in severe damage and will void your warranty. Fig. 2 below demonstrates proper and improper connections.

Safety

While LiFePO4 batteries are inherently safe, as with all batteries, energy storage devices, and electrical equipment, safety and electrical hazards do exist. Failure to follow these safety instructions may result in electrical shock, injury, or death, or may damage the battery or other equipment or property.

Installation

• The battery should be installed as per national and local codes.
• The battery should only be installed in locations approved by local building codes.
• Electrical and shock hazards can be minimized by covering the solar array and using insulated tools.
• Do not short the battery terminals.
• Do not install the battery if there are any signs of physical damage.
• Do not install the battery in a location that may be flooded.

Operation

• Use only approved battery chargers for charging the battery.
• Do not disassemble the battery.

Emergency

• Disconnect the battery from the system.
• Wear a respirator, eye protection, and rubber gloves where appropriate.
• Use an ABC type dry chemical fire extinguisher.
• Dispose of as per local regulations.

How to Properly Charge the Batteries
To properly charge your Battle Born Batteries, you will want to verify that any charging component in your system is capable of being programmed for the following specifications. Charging components can include, but are not limited to converters, inverter chargers, solar charge controllers, DC to DC chargers, etc.

• Bulk/Absorption: 14.2V – 14.6V
• Absorption Time: 60-90 minutes per battery (for parallel string)
• Float: 13.4V – 13.8V
• Equalization: 14.4V/ Disabled
• Temperature Compensation: 0/Disabled
• Charge Rate : .5c
• Battery Charge Temperature Range: 25°F (-3°C) to 135°F (57.2°C)
• Battery Discharge Temperature Range : -4°F (-20°C) to 135°F (57.2°C)
• Cell Charge Temperature: 32°F (0°C) to 131°F (55°C)
• Cell Discharge Temperature: 68°F (20°C) to 140°F (60°C)

NOTE: Not all chargers are capable of multistage charging. If yours is not, you will want to verify it can be programmed for the Bulk/Absorption voltage and have the other items mentioned disabled if applicable. Consult your charger’s manual or the manufacturer.

Connecting the Batteries in Parallel

Why Connect in Parallel?
Multiple BB8D|BB8DH batteries may be connected in parallel to increase the capacity and current of the system. When batteries are connected in parallel, the voltage of the system does not change, but the capacity and current limits are additive. For example, two BB8D|BB8DH batteries connected in parallel (shown in Fig. 3) create a 12V 540Ah bank that can deliver 600A continuously and 1,000A for 30 seconds.

How to Make a Parallel Connection

NOTE: All cables and connections MUST be able to accommodate the high currents that can be delivered by the battery. Appropriate fuses and circuit breakers are highly recommended to protect downstream components from current spikes and short circuits.

1. Identify the positive and negative terminals. These are labeled and color-coded red for positive (+), black for negative (–).
2. Determine the appropriate finishing hardware set you will use. Verify that your bolt can fully seat into the nylok insert of the nut. If multiple lugs are used, longer bolts may be required for the bolt to fully seat into the nylok insert of the nut.
3. Make the proper cable connections to the positive of the first battery. Please reference Fig. 1 for the proper order of hardware.
4. When connecting to your battery terminals, DO NOT finger tighten. Use a torque wrench to torque your hardware to the specification of 9 to 11 ft-lbs. Failure to adequately secure connections can result in severe damage and will void your warranty.
5. Connect the other end of your positive cable to the positive terminal of the other battery you are connecting to. Repeat step 4.
6. Repeat steps 3-5 for the negative connections.
7. Repeat steps 3-6 for additional batteries in the system. An example of a finished connection can be found below in Fig. 3.1 and Fig. 3.2.

Connecting the Batteries in Series

Why Connect in Series?
When batteries are connected in series, current capacities remain the same, but the system voltage is additive. For example, two BB8D|BB8DH batteries connected in series form a 24V 270Ah bank (shown in Fig. 4) and should be charged using a bulk and absorption voltage of 28.8V, and a float voltage of 27.2V.

How to Make a Series Connection

Note: Battle Born 8D Batteries are capable of being connected in series up to 48V. DO NOT exceed a 48V setup or you will void the battery’s warranty.

1. Before making any connections, make sure to charge each battery up to 14.6V with a proper lithium charger. ALL BATTERIES SHOULD BE AT THE SAME STATE OF CHARGE PRIOR TO CONNECTING, otherwise you will encounter balance issues within your system. You can check your battery’s state of charge with a multimeter.
2. Identify the positive and negative terminals. These are labeled and color-coded red for positive (+), black for negative (–).
3. Determine the appropriate finishing hardware set you will use. Verify that your bolt can fully seat into the nylok insert of the nut. If multiple lugs are used, longer bolts may be required for the bolt to fully seat into the nylok insert of the nut.
4. Make the proper cable connections to the negative of the first battery. Please reference Fig. 1 for the proper order of hardware.
5. When connecting to your battery terminals, DO NOT finger tighten. Use a torque wrench to torque your hardware to the specification of 9 to 11 ft-lbs. Failure to adequately secure connections can result in severe damage and will void your warranty.
6. Connect the other end of your cable to the positive terminal of the other battery you are connecting to. Repeat step 4.
7. Repeat steps 3-6 for additional batteries, but DO NOT exceed 48V. An example of a correct series connection can be found below in Fig. 4.1 and Fig. 4.2.

How Does the BMS Protect the Batteries?
All Battle Born Batteries come with a built-in battery management system (BMS) that protects the cells from many strenuous circumstances to protect the life cycles of the cells and your electrical system from potential damage. The BMS in the BB8D|BB8DH allows for 300 Amps continuous, 500 Amp surge for 30 seconds, and 1/2 second surge for loads over 500 Amps. All of our BMS’ protect against the following conditions:

High Voltage Disconnect ( > 14.7V)
If an individual cell voltage exceeds a prescribed threshold during charging, the BMS will prevent a charge current from continuing. Discharge is always allowed under this condition. If the batteries have not been balanced for a long time, high voltage disconnect could occur at a lower voltage. The batteries will rebalance after several full charges.

Low-Voltage Disconnect ( < 10.6V)
If an individual cell falls below a prescribed threshold during discharge, the BMS will prevent further discharge. Although the battery is in “low-voltage disconnect” mode, it will still allow a charging current.

NOTE: Many chargers must detect a voltage over 10V to send a charge to the battery. Please be aware that some chargers may not sense a battery in low-voltage disconnect and you may need to jump it with a 12V source to “wake up” the battery. You should jump your battery within 24hrs of entering low- voltage disconnect otherwise you risk damaging your battery and voiding the warranty.

High-Temperature Charging and Discharging ( > 135°F/57.2°C)
The BMS will not allow a charging or discharging current if the internal temperature of the battery has reached 135°F
(57.2°C).

Low Temperature Charging ( < 25°F/-3.9°C)
The BMS will not allow a charging current under 25°F (-3.9°C) but will continue to discharge down to -4°F (-20°C).

NOTE: The BB8D|BB8DH has an operating temperature range of -4°F (-20°C) to 135°F (57.2°C).

High Current Discharge Surges
The BMS will not allow a current that exceeds 200 (+/- 5%) Amps for more than 30s, or anything larger for 0.5s. After a high current disconnection, the battery will automatically reconnect after 5 seconds.

Short Current Discharge Surges
Our BMS has built-in short circuit protection. If the short circuit protection is tripped, the BMS will shut the battery down and will remain disconnected until you remove the battery cables. While the battery cables are disconnected, we suggest taking the voltage of the battery with a voltmeter. If it reads above 10V, reconnect the battery cables. If you are unsuccessful at obtaining a voltage reading above 10V, please give our technical support team a call.

Balancing of Cells
A passive balancing process is activated by the BMS at the top of each charge cycle when the battery voltage exceeds around 14.2V. This ensures that all the cells remain at the same state of charge, which helps pack longevity and performance.

Voltage vs. Capacity

• For a Single Battery

How to Properly Size Cables for System Install
When considering cable sizing there are a few factors to consider. First, what is the size of the load you are powering with the battery bank? Second, how far away from the battery is the load? You can do voltage drop calculations to see if you need to step up your cable size. Fig. 5 is a chart to use for reference. Do keep in mind that cables are only capable of carrying a certain amperage and you should verify the specifications of your cable and the power draws before implementing them into your system to avoid potential failures and damage.

How to Incorporate Fuses into System Install
ANL fuses are designed to melt and separate into two pieces to break a circuit in the event of excessive current. These fuses are essential components for protecting against a catastrophic event and are typically placed between Battle Born Batteries and the inverter/load.

How to Properly Store Batteries
We recommend bringing the Battle Born batteries to a 100% state of charge. Then, disconnect the battery from any loads by removing the negative cable from one battery. On average, the batteries lose approximately 2-3% capacity per month. This is subject to increasing if stored in extreme environmental conditions.

How to Maintain the Batteries
Battle Born Batteries require very little maintenance. If your batteries are in series and not being charged by a multi-bank charger it is recommended that you fully charge the batteries individually once a month if the system is used frequently. This will internally balance your batteries to ensure that they will reach their expected life span and allow you to get the full power out of them with each use. If your batteries are in parallel this is not necessary, just make sure the batteries are charged to 14.2V – 14.6V frequently for internal balance. Our BMS has a built-in passive balancing system that will take care of this for you. For more FAQs scan the QR code.
