Swollen Batteries - Solved?

[adrianoaurelio]

I have 4 batteries. 3 of them are from the Fly More combo bought in January/2018 (when I was living in NYC)

Those 3 flymore combo batteries was manufactured Oct/2017. The other Sept/2018.

All 3 fly more combo batteires was swollen - they´re about 40 cycles eatch one.

(Observation: I have seen a lot of cases of M.A. swollen batteries - make me think a production fault)

Now I am living in Brazil, and here, batteries are very expensive (about 150USD each). So to change all 3 I would expend almost 500USD.

Problably it´s not advised, but carefully, I oppened all 3 batteries (they are not glued - just docked) and punctured the cells (3) metal sleeves. Some gas out (smells funny), taped the holes and closed the batteries.

Swell is solved and the batteries are working okay.

What do you think about this? Crazyness? It´s okay? A time-bomb?

OMG!!!! Seriously - you need to get rid of that battery safely as soon as you can. LiPo batteries will explode if opened and the innards are exposed to the air. There will be a chemical reaction that will make them explode and burn quite fiercely ... Don't make the hole any bigger, and if possible patch it with duct tape ASAP. You are lucky that it hasn't already burnt.

I will give you 100 for ingenuity but 0 for safety. Seriously, don't mess with swollen batteries.

Similar Issue with mine. I think it is a factory error from DJI. Worst of, their batteries are pretty expensive here in Nigeria where I live and I am not finding it any funny.
