I Recently acquired a bunch of batteries (see picture) which I would like to use in my robot :), my only problem is that I have no idea how to charge them correctly. They are 150mAh 6.0V Ni-Hm batteries. For my project I am thinking about using 12 of them in parallel which would give me 1800mAh (would this be enough for a 5 volt Pic robot with two servo's? ). But how can I charge them all at once without wrecking them?
I hope someone can help me :).
