Hi,
I am considering installing a Victron QUATTRO with Pylontech 48V batteries. I would initially purchase 4 batteries to give me around 12kWhr when new. I would like to later add another 4 batteries - maybe 5 years down the track.
I suspect that just paralleling the old and new would be a bad idea due to the original batteries having aged and lost capacity. It would seem better to have two separate battery banks and treat each separately for charging and discharging.
Is this possible?
If so, how would this be accomplished?
What would be the recommended way to add more batteries at a later stage?
thank you,
Ron
