Is it possible to remove the traxxas connector from the battery/esc and switch to an XT60 connector? I can do that type of soldering work very easily. But, would it be safe to use? I have a stock 8.4v 3000mah NiMH battery but find it annoying to leave my (non-rc) car running to charge it. Already have a fancy battery charger/balance for my other lipos/hobby batteries and don't want to pay another $50 just for a traxxas specific one. Thoughts?
