The #3 LED on 1 of my batteries displays this after a full charge ... [size=14.6667px] My battery displays normal LEDs after I hit the on/off button once. NO LEDs lit, then all 4 showing normal full charge. What I'd like to know is ... how do I rectify this, and can I fly after this discovery? Will there be any problems???

Not good .... Tried to power up .... got this message. Looks like batt has a bad cell.

It clearly telling what to do. So do it... Send it back. Batteries have 6 month warranty...

Are you using the DJI Mavic charger?

Have it replaced, your battery needs to be in perfect condition, not worth taking any chances,

Good luck
