This is a Li-ion single-cell charger/protection circuit that can be used to charge a single cell of 15 Amp capacity or 2500Mah parallel-connected 5 to 6 li-ion cells. In this MOSFET are employed to do the monitoring task which protects our battery cells from overcharge, over-discharge, and short circuits.
Protection
Overcharge protection.
over-discharge protection.
short circuit protection.
overcurrent protection.
Wiring Instructions
B+ battery is positive.
B- battery negative.
P+ outputs the positive input for the battery pack.
P- outputs the negative electrode for the battery pack.
