Nice little 1s BMS - Chargers

These 1s BMS are just the right size. It is 1.75mm high, 37mm long and 4.15mm wide. It's small enough that you can flip an 18650 battery and you almost never see it. They're working well so far.

Pros
  • Electronics
Cons
  • write later

Great Little Protection Panels

These great little panels are a huge hit. It would be nice to have ones available with solder tags already attached, but there's nothing a quick solder can't take care of.

Pros
  • Household Batteries, Chargers & Accessories
Cons
  • Expensive

Charging worked fine, but no overcharge protection

Tested on 4 separate batteries. These batteries were discharged to 2.6V prior to charging. The board had no problem charging them fully. I purposely left a battery pack overnight to charge and the next morning it read 0V (low). Basically, the first charge went well, but there is no overcharge protection. I would recommend paying attention to loading when using these boards. The good thing is that these are 4A boards and they don't even get hot during the charging cycle.

Pros
  • Chargers
Cons
  • Some small things
