Battery series/parallel method

The correct way to connect multiple cells in series/parallel the bms of SJY LiFePO4 12V 100AH is to ensure that the total path of current in and out of each cell is equal.There are 4 ways to do this:
1. Diagonal connection. 2. the length of the cable from the inverter to each battery must be equal. 3. center diagonal connection, ensure that the length of all cables are the same. 4. Use bus bars. Note: Before the batteries are connected in series/parallel, please charge the individual battery first, and then connect them in parallel for 24 hours, so that the batteries are automatically balanced between themself.

Battery use precautions

This point in SJY LiFePO4 12V 100AH is very crucial to understand  Never drop the battery into the water. Do not put the battery pack into the fireor heat it. It is forbidden to charge and use the battery outside the temperature rangespecifiedbyus.Do not store, charge or use this product near fire and heat sources.  When the battery pack gives off odor or leaks, it should immediately stop using or stop charging,and move to an open and ventilated place, away from the fire source, and contact usintime.4)

When using the load, do not reverse the positive and negative terminals. 5) Do not short-circuit the positive and negative electrodes of the battery with metal conductors.6) The best use temperature of the product is 25±5℃, if the product is not inthistemperaturerange during use, the discharge capacity will be reduced. 7) In case of failure or abnormality during use, please contact us, do not remove the battery pack without authorization
