Alberta Lithium Marine Battery Review 

I don't have a boat but we do got a canoe and a trolling motor with a monster battery, could probably stand to lose the weight and a new and better battery for all day use

Good thing about them is they can discharge alot further than. lead acid have four times the recharge cycles and lifespan as well.

Does the lithium cranking battery charge via the outboard engine alternator (in my case a 2013 Mercury 200HP Pro XS) or does the batteries BMS cut out the alternator so no damage occurs to the outboards electrical system?

Great info .. were did you buy the blue tooth attachment..

Do lithium’s come with 4 posts ?
