Dakota Lithium

DAKOTA LITHIUM 12V 18Ah BATTERY

Engineered in a 12Ah SLA case, but with with 18Ah of Lithium Iron Phosphate (LiFePo4) technology this, battery has three times the power, half the weight, and lasts 4 times longer than a 12Ah sealed lead acid battery. Optimal performance down to minus 20 degrees Fahrenheit (for winter warriors). Plus a best in class 11 year warranty.

11 YEAR WARRANTY

World beating, best in class, eleven year manufacturer defect warranty.

CAPACITY

18 Ampere hours. Dakota Lithium batteries provide consistent power for all 18 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, especially in cold temperatures. You get all the juice down to the last drop.

VOLTAGE

12.8V

ENERGY

216 Watt-hours (Wh)

TERMINALS

F2 Terminals (spade socket). When used in salt water, or corrosive, environments we recommend applying a small amount of dielectric grease on the blades of each terminal. It helps extend the lifespan.

SIZE

5.88"L x 3.81"W x 3.88"H (149mm x 96mm x 98.5mm)

WEIGHT

4.55 lbs (2.0Kg). That's 60% lighter than a SLA battery.

LIFECYCLES (BATTERY LIFESPAN)

Up to 80% capacity for 3,000 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, +120°F max optimal operating temps (battery performs well down to -20°F). Avoid charging below 32°F.

DISCHARGE

18A max continuous, 50A max pulse (<3 sec). The flat discharge voltage curve provides a 75% bigger capacity than a SLA 18Ah battery. Please note: For small trolling motors <20 lbs of thrust, we recommend using two of these batteries in parallel to create a 36 Amp continuous discharge rate and 36Ah of capacity. This increases runtime and lifespan of the battery.

CHARGE

9A max, 14.4V recommended, 15V max. Please note: this battery should be charged using a LiFePO4 compatible charger. A SLA charger may work, but will reduce performance and lifespan of the battery.

INCLUDES ACTIVE BMS PROTECTION

Contains a circuit that handles cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection and high temperature protection for increased performance and longer life.

SERIES OR PARALLEL

BMS can support wiring these batteries in series or parallel for up to 4 units (up to 48V series or to 12V 72Ah parallel)

CERTIFICATIONS

All batteries are UN38 certified. Dakota Lithium's cells are UL1642 certified and have been tested per IEC62133 standards. Meets all US & International regulations for air, ground, and train transport.

ISO 9001:2015

Dakota Lithium is ISO Certified per 9001:2015 standards, and select models are produced in ISO 14001 certified facilities.

CHARGER SOLD SEPARATELY

This battery should be charged using a LiFePO4 compatible charger. Dakota Lithium 12V batteries should be charged at 14.4 volts, higher than AGM or lead acid. Lead acid chargers will work, but will only charge the battery to 80% of capacity.
