In my e-bike conversion feature, I talked about why I don’t trust the battery that came with the motor I put on my cargo bike. The wording from the warning section on a battery very similar to mine really drives home why:
ONLY CHARGE THIS BATTERY IN A PLACE WHERE YOU WOULDN’T MIND STARTING A FIRE. NEVER LEAVE A CHARGING BATTERY HOME ALONE. Some people put their battery and charger in a BBQ grill with the lid on so that if anything bad happens it would be contained. There are also ammo-boxes and safe, metal boxes for charging battery packs
It’s not that it’s bad advice (well, apart from not mentioning the importance of proper battery venting) — but it definitely underscores why you should buy from a reliable source with proper certificaton.
