Adding 48v LFP 100ah battery

Hi everyone, I hope you can advise on adding an additional battery.

48V 3kW Handtruck System

I currently have this simple setup right now, but stationary... EG4 3k inverter with an EG4 V1 48v LFP 100ah battery.
Its been running fine for over a year and I am looking to add another 48v LFP 100ah battery.

My ideal choice would be to add either the Vatrer or Eco-Worthy 48v LFP 100ah battery.
Anyone able advise which option would be best for a beginner?

I'm using the SmartESS app to monitor the inverter and as long as I can see the state of charge on the 2 batteries in parallel I am fine.
Are there any concern if I go with the Vatrer which has no comms?

Also do I need to balance the new battery before adding in parallel?
In this case, do I fully charge the EG4 battery to 100% SOC, then switch and fully charge the new battery to 100%?
Only then can I connect in parallel?

Is the process much simpler and safer if I stick with getting another EG4 48v 100ah battery instead?

Any advise is much appreciated.

I assume you have the Coms between the inverter and the LiFePOWER set up and that is how you are currently seeing the SOC of the battery.

To continue to do that with any accuracy, the 2nd battery will need to talk to the first. That would not be possible with the other brand batteries.

You could take another brand in parallel it with the EG4. You can choose just to leave the communications to the LP4V1 in parallel the other battery or put it in voltage mode either way it'll work just fine. Been doing it for years.

That's what most of us are doing with the ego worthy rack battery
