Works perfectly in my lead-acid replacement module
Purchased a portable oscilloscope that used an obsolete and impossible-to-find 8.4 volt sealed lead-acid battery. 2 18650 Li-Ion batteries and this 2S BMS board solved the problem.

Good for prototyping. They work well to keep the cells balanced.
Nice stenciling on the board on both sides helps you wire these modules to your battery pack properly. This module is pretty forgiving when it comes to soldering and connections. Works well.

work fine
These little charging pcbs do work, but they dont come with any diagrams or information in how to connect them. I have one in a small rc car thats running on 2) 112245 3.7v lipo cells out of some disposable vapes in series connected to one of these balance charge modules. I am using a 9v usb-c pd trigger board for an input and regulating the output back down to 5v with a small buck converter. It seems to work just fine for this setup.

At least one of the 3 was defective.
I've used 2 of these so far. The first one worked perfectly. The second one got so hot that I burned my finger on it without any load on it. Wrecked 4 of my Lithium cells in the process. There were no visible shorts, and I've always installed my BMS's correctly and carefully. This one was no different, just defective. I can't in good conscience recommend this product. 2-stars now.Update: a few days later I installed a 3rd one, also defective. Installed it correctly and very carefully. Again too hot to touch, and the battery wasn't even recognized by my testers/chargers. I replaced it with a cheap 25a bms that works. The Seller was good about refunding me for the 1st defective one, and I'm waiting for a response from them. I raised it to 3 stars because they responded so quickly. Crossing my fingers.Update: Seller responded with "friend sorry to hear that . really". So now it's a one star. The final result, 8 brand new Li-Ion Cells that were killed by these BMS's

Power out before power in
And the reverse as well. When you are TESTING these, they’ll drive you nuts. “Why no power?” “Why no charge?”But in PRACTICE they just work. I’m not overly impressed with the balancing ability, but with 150+ cells, I’m probably asking too much.
