Has anyone added batteries to 25.2

Has anyone with a VEGAS AXIS added any house batteries to the two that came with the coach?

I am looking at extending battery life during boondocking and maybe adding a small inverter for TV, laptop and maybe fan. Figure a 1000 watt inverter would be maximum.

Got two of what I am assuming are the great Harris batteries
I think second battery was an included option.

Batteries

Sounds like a good idea. I would like to add two batteries for a total of four so I could put in an inverter to run the tv when tailgating so I don't have to run the generator. Let me know if you can do it. I think two batteries Are standard on the newer models.

There is a lot of room under the chassis. You could probably fabricate a shelf somewhere to hold two more; of course getting to them once they were there may be problematic.

It looks doable. I would like to see some plans to fabricate a battery tray adjacent to the existing coach battery tray.

Kev, can't you run a modern TV on two good/quality batteries for a very long time?

Some newer TVs use very little power. If your present TV is a power hog, it may be cheaper and easier to replace the TV -- assuming that's the only reason you want four batteries.

Mo_Mike Your two batteries are enough. You just have to replenish the power. Have you thought about adding solar panels. along with your inverter
Because the inverter will drain your batteries quickly

Yes you can run a led tv on two batteries. My RV is new and the tv's are all led so it shouldn't be an issue. I just like the idea of having extra power just in case.

You could also replace the TV with one that runs on 12V; get a few more % efficiency by not having to do the 12V -> 120V -> 12V route.

You'd want to look at total efficiency. I expect new TVs like the 32-inch Samsung I bought last, which only uses about 30 watts, may still pull less power when inverter inefficiency is added. Direct current TVs I looked at a while back tended to be less efficient in general.

The interesting thing about this Samsung is that it uses a power plug similar to a phone or iPad charger. I don't recall the voltage but think the TV itself works on DC. I'll have to take a look at it again -- although I don't think it was 12-Volts even if DC.

I was looking at that Samsung as a replacement tv and noticed it had a power supply like on a laptop. Would be interesting if it would work on DC.

Unfortunately I already replaced that crappy Seiki tv. I have seen DC tv's at Lazy Days but as I recall they were pricey.

Just checked the newest Samsung I purchased and it does have an AC to DC adaptor. Unfortunately, it operates at 19 Volts DC. It would therefore require at least a DC to DC converter.

The power unit is rated 66 watts maximum output, but uses much more than that at input. Since TV's power rating is advertised to be around 30 watts average, I wonder how much DC power it actually uses -- could be less than that if it was measured at 120-Volt AC input.

I added a smaller 12v TV behind the bedroom tv. Original tv was/is mounted to door of cabinet that opens vertically... hung a swing bracket on the back of the door that allows the smaller TV to store flat against the inside of the door, but drop down when open...
Added a 12v blu ray player - and 12v adapter for laptop - and 12v to USB outlets - and allows boondocking without the genny (unless AC or microwave is needed).

Have done long weekends without electric on two batteries with no issues.
Always have the option of starting the genny to recharge - or if we want to use larger tv.

Solar is on my list for future to recharge.
