Why is it we only seem to read about Fogstar lithium battery problems,or am I missing other battery posts? No pun intended :rolleyes:

Is it because they sell more than anyone else?
I've said that several times.

My last thoughts, sorry. What is your cell UVP and UVP release set at? If at default, then the UVP release is 2.7 which has yet to be achieved in the lowest cell voltage. Is “cell balancing” turned on? And “only balance while charging” turned off?

The 105ah Fogstar is connected to my Victron MultiPlus 2000va Inverter / Charger.

I have wired it all in via a Sergeant Auto Changeover unit that automatically switches from Shore/Generator/Battery

Battery was fully charged

I accidentally turned on a 2kw fan heater. It shut down and then I got the error above.
Just a thought, renogy batteries do this, and sometimes don't come back. Some ppl put them in parallel with other battery, and they come back.
From what you describe above its a clear OCP over current protection, either the mosfets opened up and needs a setting tweaked to recover. The OCPR needs looking at.

Well at least you have a date, although it may slip a little.

Did you get a resolution, or sent it back?

My Battery was returned to Fogstar, after 3 weeks, I contacted them and was told they could not find the battery.

So they sent me a replacement out, that was delayed for several days. Then eventually, it arrived on Wednesday

All up and running again
