Built Dakota tough, this 12 volt lithium battery packs a big punch. Engineered with Lithium Iron Phosphate (LiFePo4) technology this battery has twice the power, half the weight, and lasts 4 times longer than a sealed lead acid battery – providing exceptional lifetime value. The #1 battery for fishing electronics, outdoor use, and SLA replacement. LiFePO4 charger recommended. Not designed for use in electric ice augers. SIZE: 5.94"x 2.55"x 3.78" (151mm x 65mm x 96 mm). Replaces UB1280 battery and many others. WEIGHT: 2 lb. 14 oz. (1.30 Kg). That's 60% lighter than a SLA battery. CAPACITY: 10 ampere hours. Dakota Lithium batteries provide consistent power for all 10 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. OPERATING TEMPERATURE: Ideal for rugged & harsh environments. Much better than SLA or other lithium’s. -20'F min, +120'F max optimal environmental operating temps. DISCHARGE: 20 A max continuous, 50 A max 300 mS pulse. 9.0 V max discharge, 11.0 V max recommended discharge. For longest lifetime recommended discharge rate 1-5 Amps. The flat discharge voltage curve provides a 75% bigger capacity then a SLA 10Ah battery. INCLUDES ACTIVE BMS PROTECTION: Contains a circuit that handles cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection and temperature protection for increased performance and longer life.
