I went through this about a year ago when I built and installed a 120ah LifePO4 battery. Depending on what BMS you have, there are a lot of parameters you can set, etc.
I can't tell you exactly what I set mine to, but check out Will Prouse Solar site and he talks a lot about how to charge, etc.
I don't have solar so charge from my truck so it may be different for you. The BMS will control how much charge, etc.
Good luck... sorry I don't have a specific answer for you...

Does a BMS control how much charge or just cut it off at high and possibly low voltages/temps?

Still looking for float voltage and absorption voltage. I currently have my controller set at 14.4 for absorption and 13.5 for float. Can any one verify that before we get off topic. Thanks
Not certain for your battery...but from what I have seen those voltages will work with Li batteries...I know they would with my Battleborn... Absorption @14.2-14.6V, I use 14.4V....Float @ 13.6V on mine...on all three chargers in my system.

I agree with Wallowa... I use 14.4 and 13.4 in my system.

I found some info on page 10 of the battery manual on Renogy’s site. Not sure this is the right product model.

Hope it’s useful.

The BMS will control everything and shutoff charging at what ever you set all the different parameters off at. It's crazy how many parameters there are but probably only a dozen that you might set/change.

My knowledge is limited to my Battelborn 100Ah and the BMS built into the battery can NOT be changed or program by me. But hey, I could be wrong...
