Works as expected.

Great BMS. Silk screen on the PCB made easy to wire up. No problems so far.

Great for my garden light fixtures.

I build garden lights. These are essential to not over-charge the lithium cells. Small and perfect for my use. The tabs spot-weld very nicely!

Works as it should

I needed this component to repair my CPAP cleaner. I was able to install 3.7 volt rechargeable battery, worked perfectly.

Hate that buying 10 is cheapest, one wasn’t working

I just needed one of these, and unfortunately the first one I tried was a dud (admittedly, this could have been my fault, I could have shorted it). The next one worked normally though. Quality looks good on the board

Did its job and I would recommend it

Listed exactly what I wanted it to do and would recommend to anybody. I was using it to build my own battery pack for items while on the go and it worked perfectly so that there was no overcharging happening on the 18650 batteries.

Input - Yes, Output - YES!

Great Job. I don't understand people saying that there is no "output" and they have to use the battery tabs. That's incorrect. The P+ and P- are the outputs -- solder your wires to those and you are BMS 'protected'. Lay down a couple of layers of kapton on the battery, a strip of G10 would be a nice addition, and weld the strips to the battery (component side down).

Did not burn down my house... yet

Used these to make a small battery pack for an electronics project, and so far it has not burned down my house. It does work - both charging and discharging. I have not tested it a ton, but good experience so far.I guess don't be worried that the charge / discharge specs are via an image that uses comic sans. But maybe still do? If your house burns down I am not liable. Your experience may vary.But yeah I like it so far.

Ok for non-critical battery builds

Had one DOA after a week. Been using a second one for a few months without issue. These may be of questionable reliability.
