I am leaning towards going with a Shorai LFX18A1-BS12 battery. Super light and and plenty of CCA and can handle the 18 AMP rotax alternator, from what I found during my research.

My question is, all of you that are running the lithium batteries, are you keeping them on a charger when not flying?

Is the charger even necessary? It's $90! and looks flimsy.

My odyssey 625, I kept on a trickle/maintenance charger. But from what I read, the lithium batteries, don't bleed down unless something is left on.

Also, can you jump start a lithium battery? Like get to the airport, hook up jumper cables and crank......?

Might end up staying with ole faithful, oddesey 625, but gaining 10-12 pounds of useful load is appealing and it seems that the meltdowns of the lithiums are few and far between nowadays.
