Why don't nimh's need balancing?

[What's_nitro?]

You could make a passive balancer like this (see attachment) It's meant for AA or other small-ish sized batteries, hence the low current charge. It will, however, keep them in perfect balance every time. As is would require monitoring so that the cells were not overcharged, but a circuit can be added to shut of the charge automatically. I was going for simplicity with this one.

That's great Nitro! So I could use that with a delta peak charger and... happy days
