Hi Any help gladly taken on board TB 47 will not charge. I can fire up the battery and have 25% left on it on the GO APP. Two leds on battery. However it will not charge up. Attach it to charger and the lights just stay on(two leds) but they do not "flow" as if its its charging. I have looked after the battery and deep cycled it etc as required. Any others had this problem? Oh almost forgot battery has 54 flights on it. Thanks any advance.
