MultiCompatible 2S8.4V to 9V/7.2V to 8.4V Lithiums Protections Circuit with Overcurrent Overdischarge Features

This protections board is for Lithiums Polymer and Lithiums batteries only, cannot be used for Lithiums Phosphate batteries. Please ensures that the batteries is identical, preferably from the same batches and have the same states of charge, capacity and internal resistance. This module balances both charging and discharging the batteries.
