https://northvolt.com/products/ These guys are on it. They are the leading sodium battery folks. But they have some killer LIO stuff. Not sure why they don’t have any LFP

I haven’t tested that test again. But I will. The stated voltage on the inverter is 10v-15v. I can remember seeing one of the cells bottom out at 2.5v and then rebound. So I believe it was the BMS. I also know that it happens at the top when charging as well. It will shutdown when a cell hits...

The way that I set it is with the following formula: Assume the following for a LiFePO4 battery. The lowest voltage is 2.50v and the top is 3.65v. The numbers between these 2 is your 100% or 1.15v. Eg. assume your current voltage of the pack is 3.45v average. Then 3.65 - 3.45 = .2 volts. 1.15v...

It could be low voltage on the inverter, but as I watched the voltage it was cutting off on exactly what I have it set to. I’m including a picture of the BMS.

It is a smart BMS, but the standard BT app will not let me change any rebound values. Can’t even see if it has any.

Thanks for your reply. I understand what your saying, but for an inverter, it’s ridiculous.

So I guess your saying I’m out of luck. That seems a little off for a BMS to do that. Don’t understand the logic.

I have read thru a lot of posts here and no one is describing my issue. I have a 4s 60amp Daly bms. Everything was working fine until I tested the low voltage cutoff. It did cut off, then after the battery rebounded some it cut back on in say 10-30 seconds. Result is my 12v inverter cuts on and...
