LiPo storage and charging safety

       Remove this ad - become a site supporter!

I know this topic has probably been discussed before but sometimes it doesn't hurt to review to make sure everyone remembers. So please help me out!

What I would like to know is the safest way to store and charge LiPo's. I have heard many stories of fires starting but there has to be a safe way to handle. What fire extinguisher should I have available, is there any other tips and hints that you have found worthy of note? Is there an informative book or website that you have found on the issue?

Please any information you can provide will help.

Re: LiPo storage and charging safety

I have had a lipo fire in my garage while charging some 3s batteries.i have a smoke alarm set up above the charging area and a fire extinguisher set up.just a note when a lipo fire starts nothing is going to put it out for a few seconds as the chemical reaction deminishes.never leave a charging battery,use a lipo charging bag or a metal box to contain the fire if it starts.always use your balance plug on battery.

Re: LiPo storage and charging safety

I just store mine is steel tool boxes sitting on a cement floor in the garage.
When charging I place the battery into an old crockpot liner which is ceramic with heat resistant glass lid.
Not sure what else a person could do to make things safer. Smoke alarm or two in the garage is also a very good idea!
Always stay fairly close to your lipos while charging just incase.

Re: LiPo storage and charging safety

My suggestion to add to the above is to ensure you use a good charger, and ensure you verify your charge settings before you hit enter!

Re: LiPo storage and charging safety

Best website I've found so far. Well written, not pages of forum stuff.
If you can't be kind, at least have the decency to be vague.

Re: LiPo storage and charging safety

I never charge in the house. I take my Honda 2000 generator to the field and do all my charging there. I have a 110V charging station with 2 Hyperion chargers running off an RV 55 amp power supply. It may take an extra half hour to charge when I get to the field but I feel the extra time is well spent for the safety of it. I know of a fellow who lost his whole house to a lipo fire. I transport and store the batteries in military surplus ammo cans. Lipo batteries can be very volitile if not handled properly. Always balance while charging and put a storage charge on them at the end of the day. Can't be too careful with these things.

Re: LiPo storage and charging safety

We have had a member had a fire from lipo charging...... Not a lot of details as to the setup but he plugged them in and left the house. Someone was at home but was not aware he had gone and when the smoke alarm went off thought he was just testing it.

Most lipos manufactured in the last couple of years have had their chemical makeup such to minimize actual flames ; notice I said most but not all . Some very good suggestions here .
1) Use a quality charger
2) put charging batteries in a heat proof container, lipo charge bag, heat proof container such as crock pot or corningware pot.
3) never leave unattended charging.
4) be extra careful of dropped or crashed lipos as they can have internal damage
5) lipos beginning to "puff" can be suspect batteries and could burst .
6) last but not least make sure polarity and charge settings are correct. (As suggested).
7) oh one more thing as suggested ; after flying make sure all batteries are at or close to the storage voltage of 3.85 volts per cell , not pack voltage. Recharge the day of use.
That should some it up. Fires usually start when the lithium inside the cells are exposed to oxygen ; when in a charged state.

Darren's link has some good reading. If any questions ask .
Thankf for reading.

Re: LiPo storage and charging safety

I store my lipos in a small fireproof safe from Walmart. I also charge in a fireproof safe as well.

Re: LiPo storage and charging safety

I store my Lipos in Ammo Containers but the batteries are never fully charged, after flying I bring the voltage down to storage mode. The Ammo containers are never fully sealed you don't want to turn it into a bomb. You can either drill vent holes or remove the rubber seal from the lid.
