House batteries
I have a 2017 View. There are two Napa group 24 batteries in it. I added 300 watts of solar and want to change these batteries. Thinking lithium. Seem like group 27's or 31's are most common. Has anyone made them fit? Has anyone tried Battle Born Batteries?

I replied on another forum on this very same issue I work in the energy industry the only time we use lithium batteries is for exact climate conditions, they are fickle same with Nimh which is a bit more forgiving we have replaced all of our station service units from AGM back to flooded lead acid they take way more temp control variances, discharge and duty cycles for the cost then lithium without the temp constraints my view has plenty of space im thinking about upgrading to a 6 volt system, taller batteries will fit havent figured out which group would work though good luck

Your best bet is to replace with two 6V batteries. you will double you power storage. We got ours at Costco.

Thanks
Done with my search. In order to get about 200ah's of stored power the two lithium batteries cost about $2,000 where as two 6v lead acid are $200. Golf cart batteries it is for now. Maybe in five years when these die I will look at lithium again.

The advantage of two six volt batteries is more amps to use. A pair of six volt batteries (to give you 12V) will give you 220-250 amp/hours of power. They are also true deep cycle batteries which will make them a bit more forgiving.

With the idea of putting in as many amp hours as the battery bay can hold, I just installed two Trojan 1225's.deep cell batteries. Had to modify the area a little but they fit. (I took pictures if anyone else want to do it on a View.) They are 150 ah each for a total of 300 ah.

So these would be the "golf cart" batteries?

yes
Measure your battery storage area. (length, width, and height) Go anywhere the carries or sell golf cart or deep cell batteries. Use your dimensions to find the biggest in size with the most amp/hours of storage. Once you know that they may be may combinations of 2,4,6,or 8 g volt or any number of 12 volt. Just make sure they are deep cycle and not starter batteries. If money is no object, look at lithium batteries since they are the best but at 8x the price. I went with Trojan since they had the best warranty in lead acid batteries. Agm are nice but double the price.
The bottom line is the batteries you have will work if you only go from one powered camp ground to another. The problem is time spent off shure power or your generator. The relays in the frig always need 12 v power. So if you do not have enough stored power the frig will get warm even if you think you are on gas. Happy hunting then enjoy your travels.

If these are 12V batteries, then you have 300 amp/hours. If they are 6V, you have 150 amp hours total. According to the Trojan website, 1225 cells are 6V industrial batteries and 16" tall, so yes, I'd like to see pictures of your modifications and install.

Thanks Tuscontoy,
With the TT I never went anywhere that didn't have at least water and electric. I traded from my TT to a MH so that I could do some dry camping, get in to places like North Rim of Grand Canyon.
I am having an inverter installed in the MH in early April so getting some improved batteries will be a benefit as well.

I made an album under my profile with the battery box mod pictures.

I am currently doing a 6 vdc conversion. I have found that dual purpose batteries are really not great at either purpose. That's not saying they will not work for how you use your RV. It depends on how you use it as to if it will fit for you. My house were left plugged in to shore power by the PO and ruined them. I had to change batteries anyway so the Trojan T-145's were what I wanted. Being from the boating world lots change from a 8D group to two 6 vdc batteries and have been very happy with the switch.

Just finished a 7000 mile circle around the USA. The two Trojan T-1275 batteries were perfect. Start an evening at 13 volts. With light and two tv's on all night and then coffee and toast in the morning the batteries were still 12.8. Then the sun was out and solor brought them back up. Never started the generator.

You might be surprised when those 6 volts will die. Mine were installed in 2009, still in good shape, with no problems. I have mine installed with a solar system that I installed myself. Two 75 watt panels (now 12 and 24 years old), Blue Sky Energy solar controller with remote control panel. I think that the solar controller really helps with the batteries life. The controller automatically charges and maintains charge to house batteries and also charges the engine battery. Engine battery had to be replaced at 11 years of life (still worked and tested ok but electrolyte level and dropped to top of plates and could not be filled). House batteries just require regular maintenance (add distilled water, clean outside of batteries)

OK, I'm going this way. Normally I would go 6 volt in series but this is the biggest bang in amps I can squeeze into our View24D, and I need every amp! The downside is weight but it is only another 85 lbs over the little things WGO put in, probably the best way to go.
Add another solar panel, get the dead one replaced and we should be good to go. Lovely. Note to self, lose 20 lbs, dump some more stuff I may not need.
We might watch some OTA while boondocking but the DISH receiver will be unplugged.

My Trojan's in my Duffy electric boat lasted 12 years. So I'm expecting the T-145's to perform as long as proper maintenance is done. Also the T-145's have a huge advantage over the T-1275 in Capacity Amp-Hours
T-145
5-Hr Rate 215
10-Hr Rate 239
20-Hr Rate 260
100-Hr Rate 287
T-1255
5-Hr Rate 120
10-Hr Rate 134
20-Hr Rate 150
100-Hr Rate 166
