Help with new 7.2v nimh 4200 mah packs?
I just bought two 4200mah 7.2 volt nimh stick packs from my lhs for my electric stampede, and I was wondering do I have to charge them, or do they come fully charged right out of the package? Whats the best way to tackle this? Thanks in advance

You'll need to do a form charge on them before use. Just search the forum for form charge and you should get quite a few threads explaining the process.

No batteries come charged from the factory to use, they usually have around 50% charge so you want to fully charge them before using. There are lots of chargers out there from $20 to $200, what's your budget?

Charge at 420 ma for 16 hours. Your charger probably has a 500 ma setting (.5amps) so use that. It may take 3 or more cycles of this to bring them up to full capacity. Discharge at 0.3C (1.2 amps) down to 1 volt per cell between forming charges.

Batteries need to be charge first. First discharge the battery then you can fast charg the 4 amp max is best to prolong battery life. Alway try to slow (trickle charge) your battery often. This will increase mah (run time) A Tekin 112 charger is a good charger. around $50 75 used. Make sure the firm ware charging software is H28 or higher for NIMH batteries.

Could I just run it untill it dead out of the box, then charge it from there to a full charge, or will that destroy the battery?
