Anymore info on the balancing or balancer itself?

I sent the company an email requesting the password so ill see if they send it. Should i discharge to the point where the bms disconnects or just just enough to start charging again and should i keep them in parallel to do this?

At the main negative and positive of the battery im getting 13.37 and it the terminals 5.97

Ok thanks for the advice

Yea this is 5he video i watched earlier today

Ok this sound like a good idea. Ill do that but keep monitoring to make sure they dont drain too far.

Its reading low voltage cuz of the 3 cells so i guess thats y the protect state

When i had charged them individually the delta was alot better on each of them. All 4 under 0.050. but by the time the last one was charged the soc on the first one was 99% so i put all 4 in parallel and re charged and that when the delta changed to the higher values.

Now that the batteries are almost full the delta voltage has gone way up again.

So far what im understanding is that its the high surge inductive loads that puts this inverter under pressure. The most ill be running in regards to inductive loads are a wasing machine and some drills and never at the same time. Mostly it will be running tv fan lights. Around 1200watts in...

I did this before. And i did just now again. It turns back on both cmos and dmos but its still only saying 10.455v

Thanks for pointing thst out. Ill definitely switch the lugs around.

Ok well thats a positive. I might be getting mine tomorrow so ill see.

How bad is it to run these in 24v and just work with them as is if im unable to get the adjustments correct?

Oh ok

Ive removed them i have the battery disconneced from the group.

If after i discharge it completey the bms doesnt recognize the 4th cell. I will try and configure it like u said for a 3 cell battery until i can replace the bms. If u know of any bms that i could use that wont cost a lot could u send the link.

When i check the other batteries in the app all says Number strings 4 except this one says number string 3

I sent a message earlier this morning but i havent gotten a reply yet.

Thwnks alot i will have to go and do more reading and get a better understanding of wiring and fuses.

Ok should i do it as 12v or should i do it in series parallel in 24v?

3.02 6.42 9.7 13.1 The cells arent balanced so i guess thats the voltage for each cell dont look like they should but thats essencially what it looks like.

So u connecyed the charger to the balancer and not to the battries?

I did disconnect the wires last night in trying to solve the problem.

Can anyone recommend a 24v inverter on the cheaper side for offgrid usage running 24/7 lights TV fan internet some aquatium pumps and lights and can handle a little inductive load every now and then.

When the battery was working ok once the pack voltage was under 13.7 they balance. To . 001v under load, charging and at reat. Its just when it reaches above 13.7 they start drifting alot.

I connected the inverter to the main negative and positive of the battery now and running some load so once the inverter cuts out ill try waking up the bms to see if all 4 cells come back online. Fingers crossed.

Im thinking its the bms because at the terminals with a multimeter im getting 13.8v. its just i. The app its 10.455

Currently charging. I think there is a way to make it work @Texas-Mark said with some adjustments to the low voltage and high voltage and pack voltage. I think the main issue would be pack voltage id need to set that very low but it seems the bms is still doing its job based off the cell...

No this is not changeable. It just tells the string.
