These are lithium iron phosphate (LiFePo4) batteries. From my research, supposedly all come from 3-4 factories in China. So brand doesn’t matter too much although some swear by the more expensive brands that usually come with better warranty/customer service. If you go with a cheaper one, especially on Amazon, check reviews, pass over the listings that have 100 or less reviews. I have two. One for my trolling motor that is 12v 100ah and one for my electronics that is 12v 20ah. You’ll need to know what size you need. I have read that they are not good for starting battery. They supposedly last twice as long as lead acid batteries and as you noted about the weight. They are more expensive, but cheap ones aren’t much different than lead acid. You do need a charger that is for them though. One of mine came with a charger. I’ve been using for a year and work great so far. I can’t speak for longevity yet though. But since I take batteries off of my boat every use to charge, the lighter weight has been great. Just need open water again!
BTW, when using on trolling motor, they hold a full voltage (which can be over 14v) charge for a lot longer than lead acid. So, it is recommended to not run your trolling motor on full for very long.
