Best Battery???

[mavrick0]

Good rule I always went by was if you can hold it for minimum 10 seconds then it was good.

What is the mAh rating on the battery and the mAh rating on the charger?

Nimh batteries don't like fast charging. The couple of packs I still have laying around I only charge at 1amp to get a full charge in them. When I raced using nicd's and nimh's I could charge them faster but the packs were matched. Meaning each cell was identical to the rest so they would all charge the same. Problem with generic packs is they aren't matched so when one cell is charged doesn't mean the other 5 are so it can become over charged and damaged. It goes the other way too. The weakest cell will heat up the most because of internal resistance which will also give a false peak and shut the charger off before it's actually fully charged.
