12V 46Ah Deep Cycle U1 LiFePO4 Battery – Lightweight, Long-Lasting Power in a Compact U1 Case

Upgrade your power system with the 12V 46Ah Deep Cycle U1 LiFePO4 Battery—a compact, high-performance lithium battery built for versatility and longevity. Housed in a traditional U1 SLA case but delivering 3X the usable power and 5X the lifespan, this battery is the ultimate drop-in replacement for mobility devices, small trolling motors, fish finders, and off-grid systems.

Key Features:

High-Capacity Power in a Small Package
With 46Ah of deep cycle capacity, this battery delivers all-day energy for Garmin & Lowrance fish finders, mobility scooters, wheelchairs, and 12V trolling motors under 30 lbs thrust.
Lightweight, Efficient Design
Weighs 50% less than a standard U1 sealed lead-acid battery, making it easier to transport and install without compromising power or reliability.
Superior Cold Weather Performance
Built to operate in temperatures as low as -20°F, ensuring dependable power even in freezing conditions—ideal for ice fishing, hunting, and outdoor winter use.
Drop-In Ready U1 Compatibility
Designed with identical dimensions and terminal layout as U1 SLA batteries, it’s a perfect fit for your existing battery compartment—no modifications needed.
Built for the Long Haul
Powered by Lithium Iron Phosphate (LiFePO4) technology, it offers 5X longer life, with up to 2,000+ recharge cycles—and it’s backed by an 11-year warranty for added peace of mind.

Ideal Applications:

Fish Finders & Marine Electronics
Mobility Scooters & Electric Wheelchairs
12V Trolling Motors (<30 lbs thrust)
Off-Grid Power Systems & Solar Kits
Kayaks, Camping Gear & Backup Power

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)
