I have a 5 cell 1600 mah pack in my truck. How many amps should I charge it at and what sensativitey? I have the duratrax intellipeak ice charger

1.6 amps max. 1.0 to 1.5 Amps ideal. Lower amps for better capacity, higher amps for more initial voltage... and quicker charging obviously.

If this is a rcvr pack, I wouldn't charge at more than 1amp. These small cells can't take that much heat and at the higher rates, you're basically cooking the life out of them. I charge mine at 0.5amps as much as I can and use 1amp when I'm in a bind for time.

No doubt it should be pretty close, it took me 1 hour and still can't solve the problem.

Bet the pack got hot.....hotter than it should be getting.

I charge mine at 1.5 Amps and they barely get body temp.

I used to run 1400mah IB packs in my 18th scales and at 1.5amps, they would cook the cell wrapper off the cells. They were 2/3a sized cells like are in a hump pack.

I have an Orion Marathon 1500mah hump pack that gets hot at 1amp, again 2/3a sized cells.

Yea I got a 5 cell flat pack and when I charge it at 1 amp it doesnt finish but when I charge it at .8 amp it gets alittle more than half done. Should I discharge my nimh pack before charging it?
