I know in the sailboat world they do that all the time. 10-20 LiFeP batteries hooked together in parallel being used and charged via solar and wind generators.keep in mind that some of those LiFeP batteries have built-in protection circuits and with mine at least the manufacturer strongly discourages having more than one battery connected to the load. Presumably because the protection circuits can't handle parallel connections. Don't know why. But the point is that you may not want to assume that you can just add a bunch of those in parallel later on if they don't have enough capacity to start with.
Ok so I went with the reLion 100AH lithium LT(low temp) it can still be charged in cold weather because it has heating element built in Ill also be using the BCDC1225D but I may keep both my AGMs up front with a blue sea ACR dealing with them. Not sure yet but I have everything to install either way .i picked up the battle born 12 v 100 ah and have it paired with a bcdc1225d redarc with lithium profile, so far so good, better than my 2 x 100 ah agms... i have yet to look back
good video but the technology from 14 to now is voodoo witchcraft leaps and bounds aheadPurchased a small 30ah LFE battery to run the fridge overnight. Bought a relay thermostat to disable charging below freezing. I hear some of the larger starter LFEs have heater elements in them... Not 100% sure on that though.
Im planning on charging it directly off the alternator with an isolation manager designed not to float the LFE. Should have that up and running in a week or two.
Also in my research I found this vid, thought it worth sharing:
Thanks for the details - this is very similar to the direction that I want to go. See you have a Wits End rear quarter panel mount. Will the original panel cover fit over this set up? Also, which 30ah battery are you using? Thanks!I think solar is on the short list for purchase. Here's a pic of my setup. Still some room for a solar controller.
- Ignition controlled fuse block and relay
- Coach/lfe fuse block
- Battery isolation manager for LFE batteries
- Adjustable thermostat to cut BIM charging below 0 celcius
- 30AH LFE (lower right corner)
- Crappy inverter

Oh, also I was just at Overland Expo and it was a little shocking to learn most vendors aren't familiar with LFE technology. I walked in with my wallet ready for a solar setup.
