Hello fellow steady handed friends! Alrighty I have quite a few NICD battery packs and Ive decided i want to start using them. I just started trying to charge them using a well underrated AC adapter( 3x1300mha 4.8v batteries /w/ 6.3v 240mah adapter). oddly it seems to be working and i know not why. I wanted to build a charger for it but im not sure where to begin. I cant find a circuit compatible with this and id like to build one. Any suggestions?
