This 3s 12.6V 80A protection board has built in, over-current protection, over discharge protection, overcharge protection, disconnection protection with balanced charging and discharging. It will also turn off the charging to the batteries when at least one cell reaches its maximum voltage. It can be used for Lithium Polymer and Lithium Ion cells only, it cannot be used for Lithium Iron Phosphate batteries.
Please ensure that the cells are identical, preferably from the same batch and have the same state of charge.
