Lithium Pros M3140-36CK: 36V/40Ah Deep Cycle Lithium Ion Battery Kit

M3140-36CK 36V 40Ah Trolling Battery Kit


The 36V 40Ah Trolling Battery kit we recommend for tournament anglers using 36V trolling motors.

SKU: M3140-36CK. Categories: , , , . Tags: , , , .

This is the 36V 40Ah Trolling Battery Kit we recommend for sportsman and saltwater tournament anglers using 36V trolling motors.  The kit consists of a M3140-36 lithium-ion battery and one M1236 DC charger.  At 34.8 lbs for the total kit, it is hard to believe that ONE battery can do what three group 27 marine batteries* can.

In a flats boats and other shallow water fishing boats where weight is a premium, this is the fastest, most effective, and most economical way to take 125 lbs* out of the boat.  A lighter boat is faster and more fuel efficient and can get into more places.  Catch fish where your competitors can’t.

This 36V 40Ah Trolling Battery Kit features 92 reserve minutes, or enough power for extended trolling in one area for up to nine hours.** In addition to that capacity, the on-board DC charger automatically recharges the trolling battery from the outboard engine’s charging system.

Imagine being able to troll all day long with only one battery!  This 36V 40Ah Trolling Battery Kit is the same physical size as a typical group 31 battery, so it fits in most marine battery trays.  (13″L x 6.81″ W x 8.43″ T)  Installation is a snap and you are ready to go with a Lithium Pros battery that is “strong all day long.”

NOTE:  Effective 8/1/2016, M3140-36 batteries no longer ship with a 12V e-Start post.

**Assumes 50% setting on a Minn Kota motor and 50% duty cycle (usage) on the motor. Higher settings or a higher duty cycle (more usage, such as in wind or water current) will reduce this time.
