Hello,

Reconfiguring my battery bank to 24v. My cells are new CATL 280ah cells, configured in 8s. Overkill Solar 24v BMS. Do the settings in my screenshots look ok?

Thanks!

Charge and discharge temps...

Personally, I don't want to charge over 40°C. I'll let discharge go to 50°C.

Cell over voltage is typically 3650 unless you want to give it a little margin.

Bal only when charging ON is fine if the battery is already balanced. If you need to allow for more balancing, turn it off.

You're using CATL 280ah cells, here's my Overkill solar BMS setting with EVE LF280K cells.
I changed the factory settings, then after an email with Overkill support I inputted their settings.
However, after a Top Balancing and capacity testing using a Victron 500A shunt and Battery Monitor I again fine tuned the settings to the attached screenshot below. Screenshot_20230316-145028_Overkill Solar.jpg
 
And just to clarify my previous post my setup is 12v not 24v but the individual cell % won't make a difference if 12v or 24v.
