POWER UP FOR SPRING

The more I read, for me, I'll stick with agm's 

I would advise that as well.     

My fly-fishing rig has a single Exide dual purpose battery that starts the motor, runs a MK power-drive trolling motor, a LCR, bilge, Livewell pump, and lights.   I can operate for 2 full days without recharging.     Seriously, what else do you need?

To each their own.  I use a agm starting battery in my boat. weighs about 30lb(ytx30 size). it has no trouble starting up to a 4 cylinder outboard.

Thanks Wrench, I have a 16' lowe and I'll look up the Exide dual purpose battery.  That looks more like what I'm looking for..

The ones I bought are $950.00 @ tax included. 

I will tell you Minn Kota has had a problem with Lithium power. 

Their trolling motors are very sensitive to a high charged battery, they have a protective device in the motor to prevent it from burning up from excess voltage. No problem with the AGM that comes in at 13.3v but for sure a problem with a lithium that is coming in at  13.7 or .8. 

I think Minn Kota suggests 12.8 as maximum voltage regardless if it is a 12/24/36. Size motor. 

This can be remedied by finishing your charge at 80%.   If you do fully charge it you can bleed off the charge till the motor thinks it is safe. You can also buy a lithium charge system that you can program to finish the charge at 12.8

The brushless motors don't have to worry about it, so no problem. 

I will also say and I bet Minn Kota is on the cusp of a 24/36 in a brushless.  That said paying for 2 lithium instead if 3 is a total plus and still getting the same performance. 

For about 5 or 6 years Minn Kota was simple ruling this market. I don't think they were sitting on their laurels but they got passed in overdrive. 

Going to be really cool to see what they have in store, in the one up world. 

The way I read it was if you run full power for EXTENDED times the minnkota wont handle lithium voltage.

SELECTING THE CORRECT BATTERIES The motor will operate with any lead acid, deep cycle marine 12 volt battery/batteries. For best results, use a deep cycle, marine battery with at least a 105 amp-hour rating. Maintain battery at full charge. Proper care will ensure having battery power when you need it, and will significantly improve the battery life. Failure to recharge lead-acid batteries (within 12-24 hours) is the leading cause of premature battery failure. Use a multi-stage charger to avoid overcharging. We offer a wide selection of chargers to fit your charging needs. If you are using a crank battery to start a gasoline outboard, we recommend that you use a separate deep cycle marine battery/ batteries for your Minn Kota trolling motor. For more information on battery selection and rigging, please visit minnkotamotors.com. Minn Kota trolling motors can run on Lithium Ion batteries. However, they are specifically designed to run on traditional lead acid batteries (flooded, AMG or GEL). Lithium Ion batteries maintain higher voltages for longer periods of time than lead acid. Therefore, running a Minn Kota trolling motor at speeds higher than 85% for a prolonged period could cause permanent damage to the motor.
