Great BMS board - chargers

I bought 3 of these boards to build 4S 5P 18650 batteries. Good solder pads and strong cell voltage connection. Easily attached to cells with double-sided tape before shrinking. Low Voltage Cutoff tested and working as advertised. Time will tell how these boards hold up but so far I'm very satisfied and would recommend them.

Pros
  • Ideal for me
Cons
  • No instructions

Working but not on 15A

Overview refers to 6S board. Is working. It limits the high and low voltage for each individual cell. But it heats up at 3A and gets very hot at 8A. It will not work in a battery pack (cells wrapped around it). I tested it at 10A discharge and 5A charge but it requires a heatsink. 10A is ok for my application but with a 60x50x15 heatsink. 15A will likely require a larger heatsink or fan.

Pros
  • Free for educational purposes
Cons
  • Not sure

Do not work with inductive loads, ie DC motors

Purchased for use with 18650 lithium batteries for electric vehicles modified by grandchildren. Each machine has two DC collector motors. When these circuit boards were connected to the battery packs, they would switch off as soon as the cars' drive wheels started turning. It would be nice if the seller mentioned that these boards are not compatible with inductive loads.

Pros
  • Lots of positive emotions
Cons
  • No power
