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. A Dakota Lithium 10 amp LiFePO4 charger is included.

11 Year Warranty
Best in class, 11 year manufacturer defect warranty.
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.
12.8V (Dakota Lithium 12V batteries can be used in series for up to 48V systems)
552 Watts (Wh)
M6 bolt terminals with hardware included. Easy to adapt to different connection needs (Max torque 15 ft. lbs).
7.6” x 5.1” x 6.8” (LxWxH) (194 x 132 x 173mm) - Group U1.
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.
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.
50A max continuous discharge. The flat discharge voltage curve provides 3X larger usable capacity than a U1 SLA 35Ah battery.
Recommend for longest life 10A or less (.2C). Max continuous 23A (.5C). 14V max recommended, 15V max. BMS protection from over charging will cut off at 15V. A free Dakota Lithium 10A LiFePO4 compatible charger is included.
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.
