I just got a Thunder Power 2100mAh battery for my B400. Got the EC3 soldered on and they sold me an adapter ( TP bat to DN adapter )for the balance charger end. I pluged it into the charger and the lights were blinking crazy. Looked at it closer and all the wires on the adapter are backward so the black wire was on the left side pluged in the charger that is the + side.
Did they give me the wrong adapter or will this battery not work at all.
