can i charge 10X1.2v 3000ma rechargeable batteries in series using a 12 volt 400ma current ?
i am building a r/c tank and i am using 30 1.2v 3A rechargeable nimh batteries. now i have tried charging them individually in my energizer battery charger, but they seem to get extremely hot (75 celcius) when i charge them for 2 hours. now in the tank i have these batteries in 3 battery packs that hold 10 batteries each and i want to know, if i put a 12 volt 400-500ma current through the battery pack, will that safely charge them without damaging them? recently i tested one of the hot nimh batteries out of the charger with my multimeter, and it read that the battery had 10.28 amps in it and had1.2 volts which is anbormal (exept for the voltage).also i was wondering, is it posible tocharge these packs which once run in parrell give a voltage and current of this
(10X 1.2 =12 volt 3A) X 3 packs in parrell =12v 9A
can i chareg all of those at the same time, or must i charge one pack at the same time
now before you say anything ill just add that these are individual batteries that i have placed inside a battery holder pack, also ill add that i wont buy a sla battery as ive used quite alot of money on these batteries already and lastly, i am not going to go buy a 10 battery charger as they cost way too much, unless sopmeone can find one online that costs under $25
