Based on what criteria?
Space, amp/hrs??FWIW, I’m running a single 200a/h LiFePo4…

Expion360 just released a 360 amp hour monster that we’ll soon be installing in our camper. Stay tuned…
Expion360’s New Lineup Features Huge 360 AH Lithium RV Battery
Dang, that might even make your windmill run backwards!!
After doing an extensive bit of actual Li battery testing during neighbor’s ground up V nose trailer-to-camper conversion (including 400w solar within a diversion load water heating, and powering 11kbtu air cond, and 9.5 cu/ft compressor refer) I was able to do tons of hands-on load testing which made a Li believer out of me…Solar harvest rates are outstanding…We started out with one Aims 100a/hr, and a short while later we added another…A while later, I decided to replace my camper’s two GC 6v’s with a single Aims 200a/hr and am uber satisfied…
To keep the battery above 32f I mounted the battery under the dinette seat, and repurposed the unheated battery box for regular storage – however, 120v (e.g. gen powered) battery heaters can easily be found on ebay.
Li prices seem to be slowly dropping as there are more and more offerings to be found on-line, but it seems the bargain priced batteries are using pouch type cells versus cylindrical steel cells…FWIW, The cylindrical cells are said to be of a more uniform build specification, and the bargain pouch cell types typically weigh even a pound or two less…
Charging is easily accommodated so long as the charger outputs say 14.x volts.
I’m using a OEM Progressive Dynamics 9245, using the tethered charge wizard pendant to kick it into the 14+v boost mode…Determining SOC (state of charge) can be a bit dicey, so I had to replace my otherwise outstanding Xantrex LinkLite meter with what’s an even better (bluetooth smart phone display capable) Victron BMV 12, which tracks LiFePo4 SOC’s perfectly – in and of itself, this was a fantastic upgrade!!

depends if you want drop-in or not. Custom battery setup of 400AH w/ 400 watts solar on roof and 2000 watt Magnum inverter. Almost always camp off grid and no generator and seldom have to worry about battery usage.This setup fit under the step up to the bed. Not the most simple and cheapest way to go but wanted the maximum amount power I could get in the space I had available. This setup also weighs less and fits in the same place as the two 100AH lead cells they replaced
Here’s a photo of our new Expion360 VPR 4Ever Platinum, a 360 amp hour monster, the equivalent of six 6 volt golf cart batteries.
For those that are interested, Life Line is now showing two lithium batteries offered for sale on there web site. This may not be new but it’s the first time I have ever noticed them displayed on the site. For more information call the company direct. There shipping warehouse is located in San Dimas,Ca.
