IE Tx on plug in the Batt and the little light just flashed. With any 1 of 5 other Batteries and the light is solid and the model is happy. Same issue with 2 different models, UMX Beast and Sbach. What is different about this battery?
Bad connector, maybe? In any case, I would discard the battery. Even if you get it to work, who knows if it's going to fail during flight. And you don't want that, believe me!
