I bought a 10A charger but whenever I charge my TC's battery with it, my TC gives an Error 92. It charges at 70.7V which is about the same as the original charger (I don't get the error with the original charger).

After the battery has been charged with the new charger, the battery measures 68.7V, which is below its maximum charge (which ideally is 69.7V). So why is it giving me an overload error?
