Can 6x 12V = 48V

Is this viable - Gel Batteries ?

No that will not really work as you want it too. You need 4 or 8 of the same.

Although you will initially measure 48V.
Charging and discharging a battery is done by current, and all batteries in the bank must endure the same through current. Or otherwise, you will end up with a combination of some overcharged and some flat batteries within a bank like this.

That picture is very confusing, but I see at least two dead shorts.

Phil.g00 · October 24, 2021, 11:36pm

The design is still at the conceptual stage methinks.

Why?

DaveSA · October 25, 2021, 9:47am

I have 6 batteries available and a 48V Inverter

DaveSA · October 25, 2021, 9:48am

besides the dead shorts it should be OK then

Louisvdw · October 25, 2021, 10:07am

Only with 4 batteries

Use 4 batteries and Victron Battery Balancers.

Or, here’s a plan, use an Orion 48/12 20A DC-DC Charger and charge the remaining two batteries off the 48V bank and use the 12V directly for fridge or something.

Otherwise, get two more batteries and use 3 Victron Battery Balancers and some bus bars to build this:
