They will struggle to enforce warranty abuse. They need to prove that looking at info has damaged the battery. 

My hubbles run at 3.72 to 3.73 and is not a setting i can change

Our problem was with 3 sets of dual batteries (1 bought in Des 21 and 1 in Sept. 22) where the older batteries only had 28-31 Amp capacity when the second battery was added - on own they were 100A. Inverter BMS averages readings so we only identified the problem when we added SolarAssistent
 
My experience with 2 battery setup was to log a call on email in my previous post. State all possible info with screenshots. I used this to show my batteries had different capacities
Hubble responded quickly. They first sent new firmware releases (may be different for batteries) to ensure both batteries are at correct releases. 
Hubble also suggested the AGM process using V to charge both batteries to 53.8V. 
When this failed I took problem battery in and they got the problem sorted out. 
So to recap:
* Get correct firmware versions
* Get Hubble to identify the problem by providing as much info as possible
* Then get the problem sorted out by Hubble
Hope this helps

Turns out it was a bad cable. Waiting for replacement. Thx
