I have a Skeeter ZX250 with 3 large graphs (2 on the bow and 1 on dash) using seapower as my wiring so all of that is solid. Using an AGM (biggest my dealer had) and happy with it so no issue with that. I have never had an issue with low voltage on a long day but yesterday was very hot and I was trying to run my livewell pumps on constant and got some low voltage, I don't think I generally need a fifth battery by the way I fish.

Before I invest in a "graph only" battery (which I'm not apposed to) I'm wondering why I can't run my accessories off my Impulse Lithium Batteries for my trolling motor???

On the Skeeter it would just my livewell, bilge, and lights. I have never run my Impulse below 70% on the bluetooth and that was after 10 hours with a lot of running on high in river current, normally they are all at 80/90% after a "full day".

So just wondering if I could leave my system the same and just run the accessories off one of the TM Batteries????

Anything I'm not understanding?
