I've been lugging my old school 12v 55 A-hr deep cycle battery to the flying field forever. I don't need anywhere that kind of charging capacity anymore & pretty sure one of my arms is longer. Been looking at these LiFe batteries because I can same capacity for a fraction of the weight. Or better et buy less capacity to suite my needs. I'm familiar with the chemistry in smaller cells, but just wondering if anyone is running them in boats or RVs or whatever they are intended for. Suspect they require dedicated charger for that chemistry. Also reading some specs they come with integrated discharge protection? (I assume so you don't discharge below some threshold voltage & they are pooched?). Are there names you like/don't like? Probably wont buy till next spring anyways but just wondering.
