daier 5S 15A 18.5V 5 Cell Lithium Li-ion 18650 Battery Packs BMS Protection PCB Board

This board is easy to use and install, all the pads are clearly labeled. My only issue is that the pads for the battery connections have little metal plates soldered to them that just wouldn't take solder regardless of what I tried. I had to heat them up and remove the plates from the pads but after that, the board works very well.

I received this product today, It is only BMS no wires or instructionsThe picture shows Batteries and BMS.

Soldered everything and it gives voltage with meter of 11.2 volts, but will not charge.

This BMS lacks in quality see picture

5s bms working great. It doesn't heat while charging and under heavy load. I used it for my diy portable charger using 18650 batteries.

These are pretty darn awefull. Solder pads lift and come off soon as you apply heatto them with 15 wayt iron. I even tried pretining the pads and as soon as the soldring irontouches them thdy lify. NOT IMPRESSED!!!! A TOTAL RIP OFF AND A WATE OF TIME AND MONEY!!

This product is not worth your time. It's cheap for a reason. Very flimsy.
