BAT-SAFE is a low cost safety device developed by Tom Mast, aircraft design engineer. It's easy to use, and literally put a lid on the dangers of malfunctioning batteries. They just released a Kickstarter campaign. It has the potential to become a standard to people that use lipo batteries and want some piece of mind.

Nice idea, many people in my club are using safety bags, thinking that they are safe for charging :O ; I modified portable money boxes to do the task, I didn't test if they are really safe but looks better than a plastic bag ;).

Only a suggestion, the charger seat, perhaps it's better if it is foldable or removible, don't looks comfortable to transport the box if it isn't.

The charger holder is attached by magnets only. Can be moved or removed with ease.

Brilliant product, brilliant price.  This should be mandatory for every battery user!

Nice, I do have lipo-fire paranoia lately. I think the more that drone users progress with old lipo batteries from the day they purchased their drones back a few years, the more chance of fires. I've taken to keeping them in a big old ceramic pastry bowl, but a decent product is a good thing so well done.

My idea... Add option to attach duct work to vents so I can use this indoors, and if it goes poof, it vents gases through tubes out window.

Good idea Xon, to have a little instalation inside with vent outside to charge batts if that is the smoke :O

Excellent product! I use 50 cal ammo cans right now with holes drilled into them.

Too bad shipping to Canada is listed as $40 and the box is only $29.

Another horror story and horror product


The Design (Patent Pending)

So after analyzing the problem I designed an insulated double wall steel box that contains the fire and intense heat, the smoke and soot is filtered through a steel and fiberglass flame arrestor which also reduces the heat of the exhaust gases. The clean and relative cool smoke is vented out of the box to prevent the box from exploding.  The battery still produces a large quantity of smoke but it is clean and free of soot and will clear out quickly.


It's not smart to offer product intended to burn Li-Po batteries to generate heat, exhaust gases, flames, to be operated at home (indoor).

All efforts should be directed to build safe charger and safe Li-Po batteries.

Safe charger is one equipped with temperature sensor to prevent overcharging.

Drone Li-Po batteries should come with temperature sensors by default

to prevent overcharging, fire due to excessive current consumption.

But it doesn't make sense to build a box to burn Li-Po batteries at home.

Replace metal box by plastic box with both inlects, outlets

and temperature sensors.

Never charge your Li-Po batteries closed in the box since free air flow cooling exactly prevents any fire.

Acting otherwise you built Li-Po batteries cooker

Read Li-Po batteries  ISO, EU charging, handling standards first.
