Reply With QuoteI personally went with 2-12V batteries when switching from 2-12V AGM to lithiums for my trolling motor because I didn’t want to change the onboard charger yet and it is still easy enough to swap to a 12V AGM if one of my lithiums went bad.

Lithium Battery
Looking to upgrade to lithium batteries. Currently have a MK PD-v2 24v/70# and two batteries in rear for TM plus a cranking/house battery (all group24’s). Under front deck I have a group 31 powering my black box, 106sv, and heading sensor for tm. No issue with power but would like shed some weight as a whole in boat. Thinking a 12v/50ah upfront be plenty. In rear is it better to go one 24v/100ah or two 12v100ah for tm?? Figuring both would have similar footprint and weight. Which is better route to go? 2-12’s or 1-24?

If I'm not at work or taking kids to their activities, you might find me on "The Rez" fishing. If not there, I could be in the garage working on my boat.BuckeyeCrappie LIKED above post

I am using a Ionic 12v/50ah powering a Garmin 1042, Striker, 942, & 92 Ultra XSV. The Livescope GLS10 is not connected to it but to the Cranking Battery. I have fished all day without a voltage drop to the Head Units. Also Garmin SteadyCast & NEMA 2000 Backbone is powered by the Ionic Lithium. Drew makes Solid Lithium Batteries.
