Prices are coming down on the lithium. I just ordered an Antigravity ATX20 Battery for $369 with free shipping.
I'll let you know how it works out.
Right on the case it says something about max charge at 12A. How big of an alternator you running?
I was seriously looking into LiFePO4 batteries, until my Optima died on the road a few weeks ago and I replace it with a Deka AGM.
LiFePO4 is more stable that Li-Ion, and you can get batteries that have built in BMS and can take higher charge rates. The only downside was the reserve capacity...
Keep us posted Joel!
