I just bought a arrma infraction I was under the impression you could connect 2 6s lipos for more run time. I didn't realize the 2nd connector was wired in series. The guy I bought it from before told me that he thought it was in programming so I plugged both batteries in. When I did it it didn't smoke or stink. I turned it on and it just wouldn't "start up" it wouldn't connect to transmitter and motor wouldn't initialize. Do you think I did lasting damage to it? I plugged a single battery into it and it seems to work fine I'm just scared I did lasting damage to it
