I have a 7.2v 400mah Ni-Mh battery pack(6 batteries).and the pack is concealed so i need to make a custom charger for thatcoz i have only wirrs available from the battery pack so please help me.thank you in advance
If you can add a thermal sensor, you can build fast charger, otherwise you need to build a slow charger. In either case, especially for a fast charger, you need a smart charge controller, which they make ICs for, or you can program your own microcontroller for. If it were me, I would consider a factory built universal NiMH charger.
maximum all new commonplace clever chargers will artwork advantageous with all batteries on the industry. the only project is whilst charging 2 or extra, in common terms use the comparable variety and length in mah. do not combination them. I even have one charger which will take in to 4 AAA, AA, C, or D sizes to boot as a million or 2 9v batteries.
