Thanks for the info I got the Thunder charger. I have one more question.......

I made a Tenergy 9 cell pack so I think that is 10.8 volts??? I cycled the pack 2 times discharging to 9 volts and it automatically charged it to 13.6 volts, does that sound right??

I now know I made a bad choice on the battery selection. I bought a Lipo pack, just trying to get the ones I made working so I can give them to my nephews.

Thanks for any help.

Joe
