How can I monitor a 48V Pack consisting of (4) 12V AmpereTime LifePo batteries along with (4) EG-LL Server rack Batteries?

Hey There!

Ive been looking to solve this for sometime. I use SOLAR ASSISTANT with my EG4 6500 Inverter and 4 EG-LL Server 48v Batteries.
Solar Assistant works well to communicate with those batteries via ModBus 485 ... Giving more detail on the state of the Batteries, etc...

Originally I had started with (4) 12v AmpereTime batteries to make a 48V Pack, and

I would like to continue using these along side the 4 EG4-LL 48v Batteries....

My Question is is there either a Balancer or BMS like device with Modbus 485 communication that I can connect to the AmpereTime pack?

I had thought about using a Victron Shunt , but the SOLAR ASSISTANT Software at this time ONLY Supports one connection method at a time.

And the last week or so , I have been using an EMULATED BMS which I thought would be close enough, but no..... the SOC drifted severely after about 2 weeks....

Ive looked, maybe there is a simple solution ? ..

Many thanks in Advance.!
