Hi:I'd be interested in hearing any hands on experiences with a lithium battery install in an RV. Sources, issues, curses and costs. I'm currently going through some scenarios on upgrading my battery to the 250-300 AH range (usable) for install next spring. Obviously lithium is still very pricy, especially for the 'drop in' variety like Smartbattery for instance, and that may keep me on Pb so I'd be especially interested in hearing about anyone who has gone more to the yourself route which I'd expect could cut costs a fair bit for the extra effort.

You might also be interested in Carbon Foam AGM type batteries. Similarly expensive, but less complex and chargeable at low temperatures. These people handle both Lithium and Carbon Foam AGM:http://www.bruceschwab.com/advanced-energy-storage-systems/firefly-energys-oasis-group-31/

Choose wisely. For my own use cost aside the negatives far outweigh the positive points.

Occasionally you can get a Nissan Leaf battery pack on Ebay. Usually a wrecked car etc. Not cheap (usually a couple grand) but less than half the price of a new one. I imagine if someone knows that they are doing you could have one heck of a storage capacity for the RV. The new ones are 30 KWh. The older ones are 24 KWh. It would be amazing.

To each their own For us with out any doubt the very best upgrade we have ever done to our RV LiFeMnPO4 200amp/hr battery bank Far simplified charging, No voltage sag with the 2Kw inverter, Smaller in size and even better 1/3 the total weight, etc.. But most here will NOT agreeSuggest you try a boat forum to get more up to date info

The Roadtrek Ecotrek class B comes with lithium batteries. You may find some information there.

Regarding Lithium chemistry batteries, bare in mind that they require special charging process that your typical RV charger may not have.... thus the cost of a new charger may also need be figured into the total cost.

200 amp hrs would not be enough for, even if you can use all 200

120 - 150 is NOT uncommon use for us

there would be NO excess left over for another day or night use

we have 675 ampHrs and after yesterdays rain, and some bad gas for the generator
little run time, we were at 488 ampHrs aka 69.1 percent soc this morning
down 187 ampHrs
