Possible to have Lithium and AGM batteries in the same battery

A friend has an AGM battery (has been sitting disconnected for a few years) that he has offered to give me but I already have a battery bank with two Battleborn lithium batteries. Is it OK to have a battery bank with different battery types? I''m thinking not. If it is OK, will the AGM battery be any good if it has been sitting for three years

I have grid power hooked to all 3 inverters, all share battery bank. I would like it to use grid to charge batteries once they are down to ~10% (or a set voltage, I have to figure out what voltage that would be with lifep04 cells). If for some reason batteries are dead or below like 5% and no solar available then would like the inverters to use grid to power the house. Do you

How to measure battery capacity/Battery health

Fortunately, this is for home solar, so no vibration concern. Current flow is the only issue I''ve had, and hopefully the bus bar and some cables to distribute current to multiple battery terminals will remedy it. This does add another $35-40 to my battery bank cost with the bus bar and new cables I''ll need.

48-volt battery bank SOC chart | DIY Solar Power Forum

I found some info on the manufactures (Leoch) website depicting a line graph that shows the battery''s "Relationship of OCV and State of Charge (77 degrees F.)". The line shows "Battery voltage (V/cell)" being approximately 2.17 volts per cell. Assuming there are three cells per battery, a battery''s 100% OCV SOC would then be 6.51 volts. 6.51X8=52.08 volts.
