Good day all. I just received a 400ah battery from china and want to get an accurate capacity test as lifepo4 batteries bought from china can be a hit and miss sometimes with respect to getting what you paid for. I bought a capacity tester, (attached pic), and did 2 tests but I'm questioning the results as I'm not entirely sure I had my BMS configured properly. It's funny how many videos there are showing capacity testers and how to use them but I couldn't for the life of me find a video on what to set the BMS parameters to achieve an accurate result.
I have also attached a pic of the BMS parameters I set for the second test.
I think I may know what settings were wrong but with a 400ah battery, the test takes so long I'd rather defer to someone in the know then play guessing games.
Thanks guys.
