Just got a coulpe 50 cal surplus ammo boxes of an "auction site". $24 shipped, not bad without going to a gun show. Anyhow....
My question is: If I am storing lipo batteries in them, with about a 6 foot radius in the unfinished corner of the basement, would it be better to remove the gaskets from the lids to prevent an explosion hazard from a potential lipo fire, or leave the gaskets in place to attempt to fully contain one?
What do y'all think? Any first hand experience? Thanks!
I don't have a short temper. I just have a quick reaction to B.S.
Best is to install a muffler such as used on around a 10 HP lawnmower motor. This will provide a means to vent the ammon can just in case but will help prevent flames / sparks from exiting. If it contains a large quanity of LiPoly and they suffer a chain reaction then it really make little difference. A test was conducded with a 2" vent and the lid blew violently anyway.
The odds of LiPolys going off while just setting are extremely low.
The two inch vent was a length of flexible exhaust pipe. The 50 cal. case had a lot of large LiPolys in it. Some of the cells were deliberately overcharged till........ When they started to go the latched lid was blown open the case bulged. Point being that even a large vent will not be enough if a large capacity of LiPolys are stored together and they suffer a chain reaction event.
Ever notice that most LiPoly destructive test are with 3S or less and 5000 mAh or less?
Store your Lipos at 50% charge when not using regularly. If you have the room in your basement, just build a storage shelter for them out of fire bricks. The most dangerous time is when charging them. Do not leave them unattended, or at the very least put a smoke detector above your charging area and keep a fire extinguisher handy. Most extinguishers will not put out the Lipo fire, but will extinguish those combustables that they ignite. Make sure of your cell count and charge rate EVERY time. For the ammo cans .... do not lock the lid unless you provide a lot of venting or you risk a more serious explosion.
I gotta agree with Charles. The chance of anything exploding while just sitting there is very remote. Ever go to a hobby store? The lipos are just hanging on the hooks or sitting on shelves.....and I've never heard of them just going up in flames. Same with cell phone batteries, GPS batteries, and so on. Oh, those computers that burst into flames? They were plugged in and overcharging.
They explode due to over charging, discharging WAY to fast, or damaged in a crash, but to my knowlege NEVER just sitting there doing nothing.
But I'll agree that no harm can come of storing them out of harms way.
