Product Description
This 12V lithium deep cycle battery from Dakota Lithium was engineered in a 35Ah U1 SLA case, but with 46 amp hours (Ah) 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 often provides a full day of power for 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 10Ah battery, but with 460% more capacity. Optimal performance down to minus 20°F for winter warriors. Drop in replacement for U1 35Ah SLA batteries (same size, physical dimensions & terminals) but with three times (3X) longer run time. Easily link in series to create 24V, 36V, or 48V systems. Lithium deep cycle battery durability, backed by an 11 Year Warranty. LiFePO4 compatible charger required. Save 10% on a Dakota Lithium, X2Power or NOCO charger when bundled with battery using option above.

11 Year Warranty
Best in class, 11 year manufacturer defect warranty.
Storage Capacity
46 amp hours. Dakota Lithium batteries provide consistent power for all 46Ah's. 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.
Drop In Replacement U1 Group Size
U1 equivalent for physical dimensions & terminal compatibility. 3X the usable power of a U1 SLA battery.
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 60Ah or 36V 60Ah batteries are recommended.
Voltage
12.8V (Dakota Lithium 12V batteries can be used in series for up to 48V systems)
Energy
552 Watts (Wh)
Terminals
M6 bolt terminals with hardware included. Easy to adapt to different connection needs (Max torque 15 ft. lbs).
Size
7.6” x 5.1” x 6.8” (LxWxH) (194 x 132 x 173mm) - Group U1.
Weight
10.5 lbs (4.75 Kg). That's 65% lighter than an SLA battery.
Lifecycles (Battery Lifespan)
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.
Operating Temperature
Ideal for rugged & harsh environments. Much better than SLA or other lithium’s. -20°F min, +150°F max optimal operating temps (battery performs well down to -20°F). Avoid charging below 32°F without a Battery Heater.
Discharge
50A max continuous discharge. The flat discharge voltage curve provides 3X larger usable capacity than a U1 SLA 35Ah battery.
Charge
Recommend for longest life 10A or less (.2C). Max continuous 23A (.5C). 14.4V recommended, 15V max. BMS protection from over charging will cut off at 15V. This battery must be charged using a LiFePO4 compatible charger. Save 10% on a Dakota Lithium 10A Charger, an X2Power 10A Automatic Charger or a NOCO 10A Charger/Maintainer when bundled with battery using option above. Dakota Lithium chargers should not be left connected for more than 16-24 hours. Use an automatic charger or maintainer for long term connectivity.
Multiple charging options are available with this battery to suit your various needs. 10% discount on a charger when bundled with battery using option above.
- Dakota Lithium 10A Charger - The most economical option. Must be disconnected when charging is complete.
- X2Power 10A Automatic Charger - Fully automatic charging for optimal battery health and extended battery life.
- NOCO 10A Charger & Maintainer - Charges and maintains the battery 24/7 for occasional use or off season storage.
Balancing
If this battery will be connected in series, please review Dakota Lithium's Balancing Instructions.
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.
Deep Cycle Use Only
Not designed for starting engines.
Certifications
All Dakota Lithium batteries are UN38.3 certified. Dakota Lithium's cells are UL1642 certified and have been tested per IEC62133 standards. Dakota Lithium is ISO Certified per 9001:2015 standards, and select models are produced in ISO 14001 certified facilities.
