LiPo batteries have become the most common high performance R/C battery and are used in R/C cars, boats, planes, helis, multirotors and more. However, if charged, discharged, stored, maintained, or handled improperly, LiPo battery fires can become extremely dangerous.
So Here Are 5 Tips To Stay Safe:
Never charge or use a “puffy” Lipo battery. The battery casing should feel firm. If the it feels puffy or squishy when you push on it, it means the battery is damaged, and should be discarded immediately.
Watch the video below to see an example of a puffed battery.
2. Never leave your batteries unattended while charging. Lipo fires ignite very quickly, and there’s no way to predict when it will happen. You need to be nearby to deal with the situation immediately.
Watch how quickly this LiPo battery fire starts to ignite.
3. Always charge and store lipo batteries in a fire proof container, like a metal ammo box, cash box, masonry surface, or fire proof LiPo safety bag. Avoid flammable surfaces like wood or carpet.
Don’t get the cheap Chinese knock-off bags; they’re useless (see the video below).
4. Keep a Class D fire extinguisher near your storage/charging area. LiPo fires are actually chemical type fires.
5. Use a quality LiPo battery charger that balances the voltage across each cell at all times. Never over-charge or under-discharge a LiPo battery. A healthy voltage per cell range is usually 4.2V max, and 3.2V min.
Over charging can lead to fires, and under-charging can cause permanent damage.
