2 batteries should be fine in most conditions as long as they get charged.
So how do you plan to charge them?

generally it doesn't get below 40 here most times.


The air going into the CPAP?

At 54F the heater is at 100% duty

Thanks everyone. Guess I will stick with what I have. Just tired of dragging a trailer around. My current set up works good running both machines. Volt meter at 12.9 when I go to bed and 12.4 when I get cup. This is with four Trojan T145's, 450 watts of solar and a couple hours of gen run time for a kick start in the AM.

I am having trouble with the Xantrex Inverter/charger tho. But I should start a different thread for that.

Some "Standard Size" numbers
GC-2 (six volt you need two in series) about 210-230 amp hours you can safely use half that.

Group XX.. Most of these are MARINE/deep cycle you should not use more than 25%
24 about 70-75 AH
27 just under 100
29 Just over 100
31 About 130 I'm guessing you have 27 or 29 as your "Standard"

A pair of GC-2 would give you more amp hours total and way more usable Amp hours.


Home is where I park it.
