Can you share EG4-LifePower4 with EG4 PowerPro ?

I have an 18kpv currently running with 4 EG4-LifePower4 48V . I got a EG4 PowerPro recently and want to use them all together. Is this possible and if so how should I wire it?

Yes, however, in open-loop communication. Also, for every 1 WallMount you would need 3 LifePower4's. This document should go over the pairing in detail.

I have a bank of 6 lifepower4 batteries with 1 powerpro I am connecting to the 18kvp. The whitepaper implies I can only use three of them. I need all 6. How do I do this? I also have the Lifepower4 communications hub if that helps. Also should I be connecting the lifepower4 bank to the powerpro battery connections or to the inverter connections and only connect two wires to the powerpro instead of the 4 indicated in the manual? Also do I need to do a firmware update, battery shipped Jan 4th 2024?

Those of you coming across this. I spoke to EG4 on the phone, they just say you can't hook up 6 Lifepower4 with 1 powerpro due to "sever" balancing issues. I am now asking Signature Solar to exchange three of my Lifepower4's (unopened in the box) for another Powerpro as I cannot use them... EG4 also says I need a firmware update on the LifePower4's to use them with the Powerpro, they are mailing me some sort of update tool.
 
Anything new on this? I've got 4 LifePower4 and am considering adding a WallMount. I'm running these on some older LV6548s though. @Will Prowse seems to run different batteries in parallel all the time.
 
I don't quite understand EG4's desire to parallel 300Ah of LP4 with each 300Ah Powerpro, seems like a made up rule of thumb. I have a 100Ah LP4 paralleled with 300Ah DIY and they balance totally fine even with completely mismatched wiring.

I let the 300Ah dictate all the SOC triggers based on it's own SOC and the LP4 is just along for the ride.
