this is p2 forum: batt warranty is 3 months. If past that, OP is out of luck.
Your smart batt is obviously confused. not only saying it only has 1 mah capacity when voltage cells show actual of 99%, but also reporting 95% life in assitant then 0 on batt with 5sec press!
Does it fly? Your video missed showing us what happens when:
1) you push short, then push longer to 'turn on' the batt - what happens?
2) put in phantom and 'turn on' what happens?
Your job will be to discharge it so lites on it show near empty, then charge it again to try to 'refil' it to 5200mah capacity. If you have a friend with an rc charger/discharger, they can try this for you. Your battery cells are probably still like new.
Diego, where on this planet are you located?
If where you could send it me in Dayton, OH, I would do that for you as a final last ditch hope.
BTW, what lead up to this? Ie., what happened the last few times you touched the battery?
