Thanks for posting. I had an electric Chinese made Mini RC Helicopter explode in my kitchen and I can assure you That that e bike wasn't rigged with fireworks. It almost set my house on fire. Those batteries short out and its a serious and horrid Explosion then a hot dangerous fire follows. Its a real worry on these batteries we all have in our pockets with our phones now. E-cigs, E bikes, kids scooters, kids power toys, etc. I cant shake a bit of real fear from Lithium type batteries after witnessing one of these even small batteries explode and burn like nothing else. It makes fireworks look pale. NOTE: Most happen from charging and getting over charged due to malfunction, but if a short happens it can go Blewey too. One has to trust that the Battery is Mfg right and the circuit to prevent over charging is working/That looked like he had it rigged with fireworks!!
