Thank you for all the help guys. I ended up ordering the 2cell 250mah from hobby lobby. about my other cells though, I'm a little confused about the amp draw. Are you saying that the truck needs at least 2.5 amps to run and my 7.4v 100mah pack wont work? what would happen if I tried it. Would it blow the battery? On the mutimeter if you have the polarities crossed will there be a negative symbol in front of the voltage reading? I do it one way and theres no negative symbol. I switch the positive and negative and I get the negative symbol. I am getting a reading of 3.91 volts on both cells, so do I need to balance them or anything? Thanks again in advance, you guys know your stuff.
