Battery Error 5400mAh unit P2V+

[Fuji-Flyer]

I have purchased a compatible 5400mAh battery with screen on front via eBay. After charging it suddenly gave an error ERR2 its showing 7.47v and 4443mAh. Doesn't power the P2V+ ant ideas? Or have I purchased a duff unit?

Test it by using a known good battery, a DJI authentic one. if it gives the same message it could be the contacts on the drone . Clean them up with alcohol and a soft tooth brush... worth a try.

You've been sold a lemon, I've had 2 of these **** batteries, send it back and buy an original DJI battery.
