## Customer Reviews

### ⭐⭐⭐⭐⭐ Fiddly due to size, but works perfectly.
*by S***N on 10 January 2025*

After soldering up the various connections, I couldn't seem to get it to work, using a multimeter there was no output despite the battery being fully charged.Connecting the battery upto the device, and then putting it on charge triggered the protection circuit into life, and the battery is now functioning as it should. Brilliant!

### ⭐ Don’t work
*by N***E on 30 November 2024*

Bought these to make a custom 4s battery pack and wired as per the example but output doesn’t work. Thought I was doing it wrong but looking online at others I’m right and the boards don’t work. Too late to send back now, really disappointed

### ⭐⭐⭐ works but to  tiny
*by M***M on 5 October 2024*
