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?

Gas is not human friendly and a timebomb. Always a risk to use modified battereis. My 2 cents

You are absolutely crazy!  There is a reason these Li batteries are swollen and just poking a hole in them to allow out gassing is the dumbest thing you can do.  Just get new batteries , dispose of the swolen ones and get on with it.  Just sayin!!!

It is highly discouraged to use these batteries. They can refuse at any moment, the drone will fall, and then the damage will be much more than the cost of a new battery.
