Description
Go Further with three times the usable power of a traditional U1 battery. Engineered in a 35Ah U1 SLA case, but with 46Ah 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 provides a full day of power for high amp draw 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 10 Ah battery, but with 460% more capacity. Optimal performance down to minus 20 degrees Fahrenheit (for winter warriors). Drop in replacement for U1 35Ah SLA batteries (same size, physical dimensions & terminals) but with three times (3X) longer run time. Free 10 Amp 12V LiFePO4 compatible charger included. Backed up by an 11 year warranty.
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)
SIZE
9.5”L x 6.9” W x 7.44” H (242.5mm x 176mm x 189 mm). U1 size (Group 21)
DROP IN REPLACEMENT SIZE U1
U1 equivalent for physical dimensions & terminal compatibility. 3X the usable power of a U1 SLA battery.
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 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 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. Included is a free 12V 10 Amp (A) LiFePO4 compatible charger that charges at the recommended 14.4 Volts..
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
Contains a smart BMS temperature cutoff that prevents charging when cells are below 0’F/C and protects the battery.
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.
Warranty
11 YEAR WARRANTY
World beating, best in class, eleven year manufacturer defect warranty.
About
Experience the Dakota Lithium Difference
The Dakota Lithium 12V 46Ah battery is built with Dakota Lithium’s legendary LiFePO4 cells. 6,000+ recharge cycles (roughly 10 year lifespan at daily use) vs. 500 for other lithium batteries or lead acid. Optimal performance down to minus 20 degrees Fahrenheit (for winter warriors). Plus three times the power of lead-acid batteries at half the weight.
