Dakota Lithium 12V 46Ah Deep Cycle U1 LiFePO4 Battery

The Dakota Lithium 12V 46Ah Deep Cycle U1 Battery is a powerful, lightweight, and highly durable lithium iron phosphate (LiFePO4) battery designed to replace heavy lead-acid U1 batteries. Perfect for mobility scooters, wheelchairs, marine electronics, and solar energy storage, this battery provides exceptional power, faster charging, longer runtime, and 5 times the lifespan compared to traditional batteries. It’s built to deliver reliable performance across a wide range of demanding applications, even in harsh environments.

Dakota Lithium 12V 46Ah Deep Cycle U1 LiFePO4 Battery Features

Lightweight U1 Battery Replacement

Weighs only half as much as comparable lead-acid batteries, making mobility scooters and other equipment easier to handle.

Deep Cycle Longevity

Provides consistent energy for extended periods with a lifespan of over 2,000 charge cycles—ideal for daily use applications.

LiFePO4 Chemistry for Safety and Reliability

Lithium iron phosphate technology ensures greater thermal stability, safer operation, and longer battery life.

Faster Charging and High Efficiency

Recharges up to 5 times faster than a standard lead-acid battery while offering a lower self-discharge rate for long-term storage.

Built for Extreme Environments

Operates reliably from -20°F to 120°F, suitable for both indoor and outdoor use, even in challenging weather conditions.

Dakota Lithium 12V 46Ah Deep Cycle U1 LiFePO4 Battery Specifications

Category Specifications
Warranty 11 Year 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)
Size 7.6”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 SLA U1 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.
Weight 10.5 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)

Frequently-Asked Questions

Is this battery compatible with my mobility scooter?

Yes. This battery is designed to replace standard U1 batteries used in scooters and wheelchairs.

Can I use this for a trolling motor?

Yes. It’s a popular choice for powering small trolling motors and marine electronics.

What charger should I use?

A 12V lithium (LiFePO4) battery charger is recommended to maximize the battery’s performance and lifespan.

Is it waterproof?

It’s highly water-resistant and can handle outdoor environments but should not be fully submerged.
