Battery series/parallel method

The correct way to connect multiple cells in series/parallel 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, The capacity of each battery remains fully charged and the voltage difference is within 0.5V, and then connect them in parallel for 24 hours, so that the batteries are automatically balanced between themself.
