High-current Nicad Battery Charger Circuit

| 2009/12/06

There are two versions of the Ni-cd charging circuit, one with bjt (mje2955) transistor and the other with mosfet (2sj295). There is not much difference between the output transistor changed. D1 led shows the power supply input. D2 led shows the battery is full. D3 led shows that the battery is connected to the circuit.…
