Why don't nimh's need balancing?

[What's_nitro?]

So long as they are even to start with, I've never heard of Nixx cells going out of balance.

+1 to the parallel tray idea.

That's the thing there not all even to start with 'cause they're coming from different devices. I thought the parralleling would eleviate any problems caused by this. Thanks for your input Nitro.

No no no. NO.

Serious racers do balance their nimh's. More expensive nimh's come in "matched sets" meaning they all have similar internal resistance and overall capacity.

Charging in parallel will guarantee the same voltage for all cells, but it is impossible then to vary how much of that voltage goes into the battery.

Say one AA battery is 500mah, another is 1500mah. Charged for 1000mah will cook and blow the first battery, and leave the second battery weak at only 2/3 the charge.

NO PARALLELALLEL TRAY

Especially if they have different amounts of capacity left. That would just compound the problem. (each battery requiring a different amount of the set voltage)
