The simple solution to safely charge any battery containing lithium.
If you are into drones, FPV or RC, or just using lipo batteries in other applications, be aware that they might catch on fire whilst charging.
The BAT-SAFE is a double-walled insulated steel box with a flame arrestor. Any battery within the specifications will be no fire hazard if charged or stored inside the BAT-SAFE.
In case of an accident, the smoke and soot are also filtered by the flame arrestor.
