I am planning to use 6 or 9AA batt holder from Fivemega in custom mods. The cells are wired in serie in the packs.
I do have a RC charger (Duratrax ICE) that can easily charge the whole "pack" at once.
But I don't know how to make sure the batts are equally charged in the holder. I don't have a multi-slots Ni-MH charger to make sure they are all fully charged. If I charge them one by one with my RC charger, the time it will take to charge them all, the first cell will have started to auto-discharge...
I'm not talking of everyday use... But I want to balance the pack at least the first time, and after every 5-6 recharges.
Can I use a normal charge followed by a trickle charge at the end? What current should I use then?
Also, should the pack be discharged down to 0.9Vper cell before recharging?
Thanks for your help!
