My cranking battery got me 4 years. Last couple of times had to jump the big motor while on the water. My trolling batteries aren't far behind. Time for a new battery set up.
It appears to me that Lithium batteries have stood the test of time so far and seem to be reliable... I have not seen any stories on the BBC of battery failure. Maybe I am wrong. That being said I have an ideal battery set up, and I am trying to find the best way to achieve this at a lesser cost.
I run a 24 volt Ultrex and currently have a G2 Helix 10 mega at console, a G2 Helix 12 SI at the bow. I want to add another graph, therefore I will move the helix 12 to the console and network with the Mega there. I am thinking I want a G4N Helix 15 at bow, and add Humminbird 360 and prepare to add Humminbird Live when it becomes available.
Therefore, I want to run a dedicated 24V Lithium trolling motor battery, a dedicated Lithium electronics battery and then a standard lead acid or agm cranking battery.
My onboard charger is an MK 315D which I don't think will charge the Lithium's fully.
I need input on this set up and what charger will work best.
Any and all opinions welcome, I have some time before I am able to get back on the water with fall farm chores here for a while.
Thanks in advance
