Lithiumpro 3x100AH battery capacity test (LiFePO4 / LFP)

This video is taken while doing a complete discharge test of the batteries. I will discharge them until the BMS cuts out and then slowly charge them up again at 5-10A. The batteries are now 2 years old and this is my first deep discharge test to see what kind of capacity I have with these batteries from danish lithiumpro.dk.

Logging is done by an ESP8266 board using ESPEasy firmware: https://www.letscontrolit.com/wiki/in...

Final result!

I stopped the discharge at 12.3V at ampere hours saying 292 - so I am more than satisfied!

If I would continue to 10V I would get above 300AH - but there is no need to go so far. So basically the batteries are as brand new
