Think it’s narrowed down to this company. M-Tech has great reviews and customers are saying a longer life between charges than my other choice Ionic. Although I like the Bluetooth battery check capabilities from the ionic app, longer life is the goal.
Now the decision is one 45Ah or two 20Ah so I’ll always have one on charge and the smaller size makes it easier to store in a waterproof box.

I have a 50ah LiFepo4 and would not want to carry it around all day. If you're stationary for most of the time it won't be a problem, but repositioning during a fight might be slightly more difficult. I also have a 20ah which I primarily use for electronics (kayak), rigged in a dry box, and would feel comfortable carrying it for extended sessions. If it were me I would opt for two 20ah LiFepo4 batteries over a single 50ah, unless you're stationary. I end up sitting on a kayak for 8 hours, so 50ah works well for me.
