1. Overcharge protection
2. Overload protection
3. Cut off load self recovery
4. Short circuit protection
5. Battery balancing

1. The battery connection to the controller is made strictly in series, at first 0 V then 4,2 V, 8,4 V, 12,6 V, in case of violation of this requirement BMS will not work!
2. Avoid short circuit when mounting batteries!
3. Use the same type of batteries!
4. Before installing the batteries, balance them! (balancing can be done by closing all the minuses of the batteries to each other, and plus among each other)
5. After assembly, connect the appropriate charger to BMS, to activate it!
6. Use a quality mounting wire under the appropriate current!
