Some of the cheaper battery packs cut off charging after a certain temperature is reached in the battery pack, and they only use 1 sensor...just 1 sensor.
We had a house in our town burn to the ground in 20 minutes from an EBike battery fire thios week. They are so dangerous!
People are too damn lazy to pedal a frickin’ bike?
The risk of fire alone is enough to make me not buy one of those things.
If you have an E anything; buy quality, never use after market chargers or cords only manufacturer’s, don’t plug them in near the door blocking your escape, don’t charge them near stairwells where it acts as a chimney increasing the rate of spread.
A lithium-ion battery is an inherently unstable system, particularly while being charged.
They rely on “smart power” chips to make them stable. If the chip fails with the charging current on, boom will happen.
Accident/injury rates on ebikes is very high. The owners don’t wear protective gear like a scooter or motorcycle rider would.
