Overview

EXPERIENCE THE DAKOTA LITHIUM DIFFERENCE

Go further with three times the usable power of a traditional U1 battery. Designed in a 35Ah U1 SLA case but upgraded with 46Ah of Lithium Iron Phosphate (LiFePO4) technology, this battery delivers exceptional power, half the weight, and 5X the lifespan of a typical U1 lead-acid battery—providing unmatched performance and long-term value.

KEY FEATURES

  • High-Powered & Long-Lasting – 46Ah of capacity delivers all-day power for Garmin & Lowrance fish finders, small trolling motors (<30 lbs thrust), off-grid setups, mobility scooters, and electric wheelchairs.
  • Lightweight & Efficient – Weighs 50% less than traditional U1 SLA batteries while offering 3X the runtime.
  • Extreme Weather Performance – Operates reliably in temperatures down to -20°F, making it ideal for cold-weather adventurers.
  • Easy Drop-In Replacement – Designed to fit seamlessly into U1 battery compartments with identical dimensions and terminals.
  • Industry-Leading 11-Year Warranty – Built Dakota tough and backed for long-term reliability

Specifications

11 Year Warranty
World beating, best in class, eleven year manufacturer defect warranty.

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.

Voltage
12.8V (Dakota Lithium 12V batteries can be used in series for up to 48V systems)
Size7.6”L x 5.1” W x 6.8” H (194mm x 132mm x 173 mm). U1 size (Group 21)
Drop in Replacement Size U1 35Ah SLAU1 equivalent for physical dimensions & terminal compatibility.

Energy
552 Watt-hours (Wh)

Terminals
F12 terminals (posts that screw in) with M6 size bolts. Max torque 15 ft. lbs.
Weight10.5 lbs (4.75 Kg). 65% lighter than a SLA or lead battery.

Lifecycles (battery lifespan)
Up to 80% capacity for 5,000 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.

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.

Discharge
50 A max continuous discharge. The flat discharge voltage curve provides a 3X bigger capacity then a U1 SLA 35Ah battery.

Charge
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.

Includes active BMS protection
Contains a high discharge capable circuit that handles cell balancing, low voltage cutoff (10V) preventing over discharge, high voltage cutoff (15V) preventing over charging, short circuit protection and temperature protection for increased performance and longer life.

Cold temperature charging protection
No low temperature protection

Certifications
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.

Trolling Motor Compatibility
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.

Recommended Charger
12V 10A LiFePO4 charger (Sold Separate)
