This is Li-ion single-cell charger/protection circuit which 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 from short circuit.
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.
