Where does everyone store their batteries in the summer? I currently have mine in the garage in a lipo bag. I am planning on purchasing an ammo can and putting a couple of holes in it for ventilation.

The garage is attached to the house and doesn't seem to get to warm in the summer. I had 1 battery that had a bad balance plug sitting on my bench and the case split and puffed (reaction 5000 2S) Nothing caught fire thankfully.

Now I'm paranoid about the batteries. I had put them all in storage mode after every use. (typically race once a week) They are being stored at 3.80v per cell.

Any advice or recommendations would be greatly appreciated.


Also how many charges do you typically get on a battery before its time to throw it out?

Old ammo can bought at a military surplus store. Bought my lipos in 2011 or 2012 and even let them sit for a few years (in the ammo can). I did check on them, on occasion and charge/discharge them about once a year during that time. I did have one puff and I dipsosed it at the local Best Buy collection box. I never store them when they are not in the proper storage mode from my Cellpro charger.

best for a cool dry place, as close to 32°F as possible without freezing (crisper drawer in fridge for long term [weeks on end] storage is probably not a bad idea) will ensure the longest lifespan:

good chart above thanks for posting it.

I bought a metal suitcase just like you would have your transmitter in from somewhere and I have all of my batteries in there. Everything is at storage charge. I try to cycle them to full charge, full discharge, and back to storage charge at least once every four months ... If any battery starts to look really puffy then I get rid of it, a little bit of puff I don't mind but I will keep an eye it. All of my batteries are in my house in a room that I'm frequently and so they're not tucked out of sight. Honestly if they went up in flames there's not much I can do about it but I think regularly cycling them and looking at their physical appearance for issues and keeping them stored in a place where the temperature is constant is about as safe as I can get honestly if they went up in flames there's not much I can do about it but I think regularly cycling them and looking at their physical appearance for issues and keeping them stored in a place where the temperature is constant is about as safe as I can get. I guess putting them in a heavier metal box might be safer but it would definitely have to be out of my house which would be in an area that I couldn't control the temperature is much so that's the trade-off
