I roll my own battery packs and normally make them up from
1.2 V NiCd cells that I pull from cordless drills.Some info here on my web site if you're interested:
If the mixed cells have different capacities though, it's easy to end up with HOT packs.
So how to determine capacities for different cells? Charge them up fully and then time how long they last with a given load? Is there an easier way?
Also...
There's a web site here that says you should NOT roll your own NiMh packs.
Does this sound right? I sent a note to the author asking for some citations but didn't receive any reply.
Thanks for any help. DOC
