Markocaster, thanks for the reply/suggestion. You know what? I should explain: originally, I wasn't going to ask Erik at Imex, because I figured since it's been several months plus since I bought the battery pack from Imex that it would definitely be too late for me to return/exchange it. But upon reflection, Erik has been a really fair and reasonable guy to deal with in the past (I've bought two Taigen tank kits and my RTR tank and a lot of Taigen parts from Imex). So maybe (as you point out) he can give me some suggestions on how to fix the battery. So thanks again for your post!
