UPDATE
I purchased a Minn Kota c2 30 pound thrust motor yesterday with a max draw of 30 amps.
The motor was bow mounted and ran great all day at all speeds with no battery shutdown. The only new issue is one of the batteries was almost dead while the other one was still full?, still wired in...
I feel like maybe I should just sell these batteries and buy a 100ah agm battery. I don’t really have the time to do any testing and don’t really need a huge power supply adding another battery for 150-200 bucks
Someone please help-
I purchased 2 Power Sonic PSL-12450 Lifepo4
They are rated 45Ah 25a draw each
I have them ran in parallel to get 90ah and 50a draw
My trolling motor is Minn Kota 55 lb thrust
50a draw
It will run all day up to speed 3
On speed 4 and 5 the batteries cut off and then reset...
Positive to one battery, negative to the second battery, also strange is it will run full speed out of the water but not under load in the water, so it’s tough to troubleshoot
