One caution: Although I'm a hardcore e-bike enthusiast, the ultra-crappy Chinese battery chargers many of them come with need to be outlawed. They are a huge fire hazard and at best they shorten battery life.
Building good Li-Ion chargers that don't overcharge or overheat batteries is known technology. Those features might add $10 to the cost of the crappy chargers, and their use should be mandated by law.
- relyks 3y agoThere have been safety standards for e-bike batteries recently mandated by law in places like NYC, but there is still a lot of lacking enforcement and mandatory checks. Every other week, you hear an instance of a person's apartment or repair shop set on fire due to faulty e-bike batteries :(
- sleepybrett 3y agoYeah, often it seems to be delivery drivers who are really hard on their batteries. There is a grey market to repair them when cells go bad and they often use low quality replacements or override some of the safety circuitry built into a lot of the batteries.
