Lighter, muuuuuch stronger, lasts pretty much forever, no nasty acid leaking out and gooping up your vehicle, but holy smokes these things are expensive!

Here's a video from a pretty well known guy in the EV world about how to build your own LiFePO car battery:


I went through and added up the costs, and its around $300 CHEAPER than the solar-electric one above, still well over $500.

We went to one of these on 4580 and 4488 after an optima yellow top almost killed me.  Very small, about 3 lbs in weight, could start the engine all day long and even handle winch work.

I don't remember off the top of my head.  Was sold as a Jet Ski battery by one of the parts stores.

Lithium batteries are all the rage in powersport now. They are crazy light.
