This is the 12.8V 150Ah Lithium Ion Engine Start Battery we recommend for freshwater and saltwater tournament anglers for use with all outboards. At 36 lbs, it is hard to believe that ONE battery can do what two group 31 marine batteries* can.
The M31150-S is a Lithium Ion Battery for the angler who will accept no compromises in a starting battery. This is the most capacity that we can fit in a standard Group 31 case. (13″ L x 6.81″ W x 8.43″ T)
It features one of the most advanced internal battery management systems in the marine industry today. This fully integrated digital battery management system insures long life and trouble free service all safely sealed inside a lightweight box. This battery features 1,500 Marine Crank Amps (Eq) and will have no trouble starting all conventional outboard engines on the market today. It can safely be used with any outboard charging system that is AGM and Gel battery compatible including Mercury, Yamaha, Honda, and Suzuki. This battery meets the Sept 19, 2022 Mercury specifications for a lithium-ion engine start battery.
The M31150-S Marine Starting Battery has a whopping 360 minutes of reserve capacity, the highest on the market in a Group 31 case. This is the battery of choice for boats with multiple 12″ graphs with pro anglers using this battery with up to five graphs running simultaneously.
Having trouble with graphs resetting during an engine crank? The high power Lithium Iron Phosphate (LiFePO4) chemistry used in this battery holds a higher voltage as it is discharged eliminating this “reset” issue. Avoid going to two 12V lead acid batteries when moving to 12″+ for graphs and forward facing sonar by choosing Lithium Pros!
Charging is simple because your existing 12V AGM battery compatible charger will work fine.*
In spite of all the power contained in this battery, it still ultra lightweight at an amazing 36 pounds! That's 1/4 of the weight of two Group 31 AGM batteries.
NOTE: Not for use in series to make higher voltage packs. 12V systems ONLY.
Orders placed today are estimated to ship on April 5th, 2023.
*Group 31 marine battery assumed to be 220RC and 76 lbs.
*Insure the charger’s float voltage is 13.5V or less and the charger never exceeds 14.8V. Do not “de-sulfate” any lithium ion battery.
