Yep, that's sadly on why I hate smart technology
Or
Unless someone makes like a adapter for the spektrum batteries to use on regular ordinary chargers. I seen it done with Traxxas batteries, but not sure on spektrum
@Greywolf74 ,
@WickedFog and
@tntpoof might know
Hold on, are you talking about the third wire on the ESC for the car? If yes, idk about that wire, probably doesn't need to be used. If it's a third wire on the battery, it's for the spektrum smart tech.
Picture of the battery and ESC could be helpful.
