Excellent product, working as described. Good seller, fast shipping and delivery. 100% recommended seller and product.

Buenas

This item worked as designed. Happy Camper

Very small footprint, easy to incorporate into a project battery pack.

12.6v in to charge, not 240v! I wanted to see what the low voltage cutoff was. I took one and connected a resistor divider to the voltage taps and an LED to the output. It turns off at 7.6V which is 2.53V per cell. That’s the absolute maximum discharge voltage before cell damage occurs. I wish that it was 9v instead.

These apparently do not have an OVP/Overcharge protection function, but it's my fault for not fully reading the description and learning that these only advertise overdischarge / undervoltage protection.

All were BAD

So I got a couple battery packs hooked up but it doesn't seem that they allow it to be charged through this bms, not sure if I'm missing something and if I am let me know cause I'd love to get it back up and going but it doesn't seem to be working as advertised

He conectado 2 y han funcionado bien, son recomendables.

Good
