Built Dakota tough, this 12V dual purpose lithium battery with 25 amp-hours (Ah) of capacity and 300 cold cranking amps packs a big punch. Engineered with Dakota Lithium’s signature Lithium Iron Phosphate (LiFePO4) technology this battery has twice the power, half the weight, and lasts 5 times longer than a lead acid or AGM battery – providing exceptional lifetime value. The dual purpose BMS provides exceptional safety, reliability, and versatility, giving you exceptional deep cycle performance for running onboard electronics, plus 300 CCA's of engine starting power for use in ATVs, UTVs, lawn tractors, generators, and other small gasoline engines. Same deep cycle performance as our legendary 10Ah battery, but with 150% more capacity. Replacement for 18Ah & 20Ah SLA batteries including size UB12180, FM12180, 6fm18 and others. Dakota Lithium deep cycle battery durability plus dual purpose versatility, backed by an 11 Year Warranty. LiFePO4 compatible charger required.

11 Year Warranty
Every Dakota Lithium battery comes with a best in class, 11 year manufacturer defect warranty.
25 amp hours. Dakota Lithium batteries provide consistent power for all 25Ah. LiFePO4 batteries have a flat voltage curve, which means they have a steady power output as the battery discharges. The power output will not dramatically drop like similar sized SLA batteries. You get all the juice down to the last drop.
300 Watt hours (Wh)
Cold Cranking Amps
M6 terminals (posts that screw in). 2 sided terminal block allows for side or top installation. When used in salt water environments we recommend applying a small amount of dielectric grease on top of each terminal after installation to help reduce corrosion (Recommended Torque 5 ft lbs, Max Torque 9 ft lbs).

6.4 lbs (2.9Kg)
Lifecycles (Battery Lifespan)
Up to 80% capacity for 3,000 cycles in recommended conditions. The typical SLA has 500 cycles. Dakota Lithium batteries last so long that the price per use is a fraction of traditional batteries.
Ideal for rugged & harsh environments. Much better than SLA or other lithium’s. -20°F min, +120°F max optimal operating temps (battery performs well down to -20°F). Avoid charging below 32°F.
30A max continuous, 300A max pulse (<5 sec). The flat discharge voltage curve provides a 75% larger capacity than a 25Ah SLA battery. Please note: a single battery is only appropriate for trolling motors with <20 lbs of thrust. For trolling motors with 20 to 30 lbs of thrust a DL 46Ah battery is required. Or you can combine two batteries in parallel to create a 50 Amp continuous discharge rate and 50Ah of capacity. This provides the amps necessary to run the larger motor, increases runtime, and lifespan of the battery.
30A max, 14.4V recommended, 15V max. This battery must be charged using a LiFePO4 compatible charger. Can also be charged by ATV, UTV or powersports engine alternator (<30A output). Select the option above to bundle with a Dakota Lithium charger and save $.
Includes Active BMS Protection
Every Dakota Lithium battery contains a Battery Management System (BMS) that handles automatic cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection and high temperature protection for increased performance and longer life.
Smart Dual Purpose BMS
Optimizes battery for use in both deep cycle applications and engine starting applications and allows for the battery to be charged by a power sports, tractor, ATV, or UTV engine alternator.
Charger Sold Separately
This battery must be charged using a LiFePO4 compatible charger. Option to bundle and save with Dakota Lithium charger is available above.
All batteries are UN38 certified. Dakota Lithium batteries are UL1642 certified and have been tested per IEC62133 standards.
Drop In Replacement
Replaces size UB12180, size FM12180, and size 6fm18 SLA batteries with twice the run time and half the weight.
