#GoFurther with three times the usable power of a traditional U1 battery. Engineered in a 35Ah U1 SLA case, but with 46Ah of Lithium Iron Phosphate (LiFePO4) technology, this battery has three times the power, half the weight, and lasts 5 times longer than a U1 sealed lead acid battery – providing exceptional performance & lifetime value. 46 Amp hours of capacity provides a full day of power for high amp draw electronics like Garmin and Lowrance fish finders, small trolling motors (<30 lbs thrust), off-grid applications, mobility scooters and electric wheel chairs, or anything where you need a longer run time. Same performance as our legendary 10 Ah battery, but with 460% more capacity. Optimal performance down to minus 20 degrees Fahrenheit (for winter warriors). Drop in replacement for U1 35Ah SLA batteries (same size, physical dimensions & terminals) but with three times (3X) longer run time. Free 10 Amp 12V LiFePO4 compatible charger included. Backed up by an 11 year warranty.

How long will my battery power my unit?
Take the amp draw of the unit Multiplied by voltage (12) = watts
Divide watts by the Wh of your battery (2400) = run time at FULL/HIGHEST settings
Extend this run time by turning down settings
VOLTAGE 12.8V (Dakota Lithium 12V batteries can be used in series for up to 48V systems)
SIZE 9.5”L x 6.9” W x 7.44” H (242.5mm x 176mm x 189 mm). U1 size (Group 21)
WEIGHT 10.5 lbs (4.75 Kg). 65% lighter than a SLA or lead battery.
STORAGE CAPACITY 46 ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 46 amp hours. DL 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.
LIFESPAN/LIFECYCLES Up to 80% capacity for 6,000 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.
DISCHARGE 50 A max continuous discharge. The flat discharge voltage curve provides a 3X bigger capacity then a U1 SLA 35Ah battery.
CHARGE 100 Recommend for longest life 10A or less (.2C), Max continuous 23A (.5C). 14.4 V recommended, 15 V max, BMS protection from over charging will cut off at 15V. Included is a free 12V 10 Amp (A) LiFePO4 compatible charger that charges at the recommended 14.4 Volts..
OPERATING TEMPERATURE Ideal for rugged & harsh environments. Much better than SLA or other lithium batteries. -20'F min, +150'F max optimal operating temps (battery performs well down to -20'F). Avoid charging below 32'F. Discharge cut off at - 20'F / -20'C. Charge cut off at 23'F / - 5'C. BMS high temp cut off at 167'F / 75'C.
TERMINALS F12 terminals (posts that screw in) with M6 size bolts. Max torque 15 ft. lbs.
SAFE & RELIABLE Includes active BMS protection circuit that handles cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection and temperature protection for increased performance and longer life.
Contains a smart BMS temperature cutoff that prevents charging when cells are below 0'F/C and protects the battery.
All DL batteries are UN 38 certified. Dakota Lithium's cells are UL1642 certified and have been tested per IEC62133 standards. Meets all US & International regulations for air, ground, train, & marine transport.
Perfect for trolling motors with 30 lbs of thrust or less. For larger 12v motors the DL+ 12V 60Ah battery is recommended. For 24V & 36V trolling motors the single 24V 60 Ah or 36V 60 Ah batteries are recommended.

**All lithium batteries (LiFePO4 included) must be shipped via ground shipping. Typical delivery time in the US for in stock batteries is 5-7 business days plus 1-3 days lead time to pack and ship your battery from our warehouse. Lithium batteries cannot be shipped overnight, or express due to federal shipping restrictions. The USPS does not allow for batteries to be shipped to Post Office boxes (PO Box).
