Good talk on ebike battery fires by Jason from Grin/ebikes.ca
- Li-Ion cells from vendors other than Panasonic, LG, Sony, Samsung have much higher failure rates even when the battery is otherwise executed correctly. They couldn’t set an unprotected MG1 on fire via over discharging or overcharging.The internal cell pressure disconnect open the circuit.
- LFP is inherently safer and it’s okay from other vendors. It’s cheaper too, but lower density - less range.
