Correct me if I’m wrong guys, but I don’t believe I am aware of any companies offering a 24 volt agm battery?
12, 24 and 36v lithium batteries are all readily available in the market, they are just pricey and also require a special charger, BMS and in canada cold weather charge protection needs to be considered depending on your fishing preferences/storage situation.
if you don’t fish much in cold weather, and are able to store your boat in a garage, are limited in space (as you are) and are into the idea of weight savings, I’d most certainly explore that option, but you are going to pay for it.
you’ll want at minimum 100amp hours of capacity for your trolling motor battery.
I see that Amazon has finally started selling their “cheaper” 100ah 24v lithium’s up here. Some folks swear by em.
lots of guys are also running 2 24v 60ah in parallell, for some cost savings and space savings.
