1. if you need LED screen and bluetooth function , tell us.

2. Before you place an order, you need to contact with us : charger(how many), Bluetooth function, LED screen. What you will use it for ? (to determine which cell to choose), and then how much the maximum power of the load W ? and how much -maximum or continuous discharge current A ? . These questions are used to determine which BMS protection board we will use .

3. All models of shell material, weight, size, color, BMS can be customized

For 12V 120Ah battery
- Series: It is not recommend to connect more than 4 batteries in series .
- Parallel: It is not recommend to connect more than 4 batteries in parallel.
- DO NOT string batteries in series and parallel at same time. Doing so can cause catastroph-ic failure.
2. Dos
*Before making any connections, make sure to charge each battery up to 14.6V with a
CONNECTING, otherwise you will encounter balance issues within your system.
*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 componentsfrom currentspikes and short circuits.
*In parallel battery banks , the cables between each battery should be of equal length to
ensure that all batteries in the system can work equally together.
*To string multiple batteries in parallel,first connect the positive terminals of batteries to
each other. Then do the same with the negative terminals . Finally, connect the positive and
negative terminals of the first battery to the system. This type of arrangement is used to
increase the overall battery capacity while keeping the voltage the same.

A: No sir, maybe you know the cycle life of cell is not only depends on the quality itself , but also be affected by the discharge/charge rate the actual temperature. So it is unresponsibility at all if a supplier tell you the cycle life but no talking about the actual usage. For room temperature 25℃ and 1C discharge and 0.5C charge, the cycle life of the battery pack can exceed 4000 cycles and warranty 5 Years, only energy storage usage.

4 Q: Can these battery pack be compatible with my inverter? do you have a company list of the inverter which is compatible?
