New LiFePO4 installation charge parameters

[Muskoka]

My Classic 150 Lite just suffered the "0" percent Soc. No idea why, went to check the Classic Monitor app on my phone and it shows 0% Soc, confirmed on the Classic itself. Ideas, how do I get the true state of the batts back, wait until next full charge cycle?

Should add, the bank isn't actually zero, should be around 50%.

Another thing that's odd, the Android app reports the Total Capacity of the bank to also be "0", I just checked in the Classic, and it's showing the correct amount, 280ah.

Did a VMM back to Flooded, reprogrammed the controller, all numbers reporting correctly now, of course the SOC isn't accurate, but it's working. Looks like Monday before the sun returns.

yes, nothing is 100%, But that accuracy takes time to calibrate with any SOC.
Might take some tweaking around but it can be achieved

That's why I mentioned no sun till Monday, once I'm back to 100% after a full charge it will sort itself out. At least it always has since I installed this CC close to 15 years ago, time flies.

Hopefully this 0% soc "bug" can be sorted out so we can set "Lithium" after a VMM. Funny, or I suppose not so funny, how it worked fine for quite some time, well over a month with the updated firmware, then acted up out of nowhere.

I had the 0% SOC when I first installed the lithium firmware, but it went back to normal the next day and has been fine ever since.

This is weird.   I know of one Classic 150 that still shows 0% SOC with this newer 3798 and 3800 version software nearby here in AZ.  I'm looking into it but so far I do not see a reason.  Probably just 150s then ?  That does not make sense either.  Most of the software is the same for all genres of Classics except for current and voltage limits pretty much.

Muskoka, please keep us posted, especially on Monday.

It is sunny here in the Phoenix area but supposed to be 92 today.

Will do, ya it's odd because the soc has been fine since I installed the new firmware Feb 5th.

I'm back on Flooded, do you want me to switch back to Lithium again?

Well, it shouldn't make any difference but sure.  Give it a try.  Let's see if battery type matters

[Muskoka]

Got sun today, soc not acting correct, total ah of the bank was set correctly, then reverted back to 400ah on it's own.

I've switched back to Flooded, everything seems stable, working better, in that mode. At least when I set the bank ah to 280 it stays there. It's more important to me that I know, or at least have an accurate count of ah in, ah out, so I'll leave it on Flooded for now. I can't use my system blindly, I need accurate soc, ah counts, in, out.

OK thank you Muskoka.

My 200 here is in Lithium mode and SOC appears to run fine.

The capacity is set to 100 Amp-Hours and has not changed back to 400.

Weird stuff happening but SOC "should" not change the way it works.

Will figure it out before we release it.

I really appreciate your help.

Hi boB,
When on the boat this winter I updated to the lithium code on my 150s. I did the VMM.  Since then SOC remains steadfastly at 0. Battery capacity is correct at 440Ah but SOC will not change from 0. Everything else seems to work correctly as far as I could see.
Now off the boat and back home.

Maybe try another VMM and see if it changes the next time batteries fill up.
My 150 had the 0 percent but then it went back to normal functioning. I am just speculating I had done a few VMM and maybe that helped fix it.

If VMM does not work you might want to check the wbjr.
I had one that kinda failed but appears to work .
It is on one of these threads
