I was curious how this is done. It seems you would have to vary the voltage and current to measure resistance from 1ohm to 10Mohm.
Recently I was toying with a digital multimeter and observed the following. The multimeter was set to measuring AC voltage with the upper limit of 750 volts. It has two probes which I will call "red" ...
I'm thinking of building a general purpose battery charger. It would charge LiPo packs, 9V, AA, AAA, etc... I've been doing a bit of Googling and read that the internal Phone charging circuits tend ...
I have some lipo batteries I'd like to test. Ideally it would do the following: how much time does it take to discharge to minimum allowed voltage? how flat is the discharge curve? how many mAh ...
