3RD Battery

[ted 95]

I'm looking at changing the batteries in our unit to AGM 31.
Has anyone ever added a 3rd battery.
I'll measure it but it looks like it will fit.

I think it will work - might need to see if the charger will be correct for the 3 batteries with the correct voltages for the different phases of charging.

I was thinking of removing the existing 2 boxes and adding a 4 battery box. I have been using two 6 volt batteries since the DW is a 50 amp kinda girl..
I did find a duel battery box, and then I found the 4 battery box on ebay for around $70 (as I remember) that would fit the space allocated for the batteries.
I guess since I am in the 6v world - I have to work in pairs.

Good luck!

I have 4 - 6 volts in a battery box.

The 3rd agm should work when wired in parallel.
