Hi everyone,

I have 3 batts, 1 is 60+ cycles and the 2 are 28 cycles. The last time I used them was 3 weeks and 5 days ago. After using them earlier today, i noticed while looking through the vents fromthe side of the batts that some cells were a bit bloated. After letting them cool down, i noticed that the bloating seemed less. Hooking them up to the p4, batteries registered as normal and all cells are of the same voltage.

Should i be concerned? These batts are only around 10 months old ( the 2 being new are around 7months).

Thanks!

I wouldn't worry too much from what you describe.  When they start looking worse such as in the vid below (you can see the center beam is bowed out a bit), you might be a little more concerned.  MHO



Be sure you're caring for them properly - meaning don't keep them fully charged.  Wait to charge them just before you're about to use them.  

Have a read of the Phantom 4, Intelligent Battery safety guidelines Here

It would be usual to store them with 50-65 % charge. They will self discharge slowly after a period of 3-10 days, as set by user in DJI Go 4 App'. So shouldn't be a problem. And they also recommend a full charge cycle every so often (in guide notes).

Just a little heat. No worries.

Looks as though you need to burp them...the bloating should decrease. Listen closely for the burp then change the diaper!  Ha!
