Dakota Lithium 12V 135AH Specs

Storage Capacity

135 Ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 135 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)

Engine Starting Power

Lithium battery equivalent to 1,000 Cold Cranking Amps (CCA) of lead acid battery engine starting power. Suitable for automotive and other applications. Marine Outboards: Please refer to your manufacturer recommendations.

Size

9.5”x 6.9”x 7.75” (242.5x176x197mm) Group 24 equivalent

Group Size 24

Group 24 compatible physical dimensions & 24F terminal orientation. Group 34 compatible. Cranking power (CCA rating) & usable deep cycle capacity is much higher than a lead-acid battery of the same group size. Group 24F 24R 24H 24T compatible. BCI Group GC2. M27-1000 compatible.

Energy

1620 Watt-hours (Wh)

Terminals

M8 size bolts. Includes a terminal adapter kit with automotive & marine posts that screw into the M8 bolt terminal, and M8 brass terminal bolts. Easy to adapt to different connection needs. (Max torque 15 ft. lbs.) (Max 5 ft. lbs. on terminal post adapters)

Weight

27.2 lbs (12.3 Kg). 65% lighter than a SLA or lead battery. 1/2 the weight of a normal car battery.

Lifecycles (battery lifespan)

Up to 80% capacity for 2,500 cycles in recommended conditions. The typical automotive 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). Internal even-heat technology allows for charging below 32°F. BMS high temp cut off at 167°F / 75°C.

Discharge

135A max continuous discharge, 1000A max 2 second pulse, 900A max 5 sec pulse. The flat discharge voltage curve provides a 75% bigger capacity than a 135Ah SLA battery with the same CCA rating.

Peak / Continuous Charge

Recommend for longest life 70A or less (.5C), Peak charge acceptance 165A max for one minute, 200A max BMS cutoff. Max continuous 150A (1C). 14.4V recommended, 15V 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..

Max Charge / Alternator Size

Peak charge acceptance 165A max for one minute, 200A max BMS cutoff. Drop in replacement for lead acid and AGM starter batteries for vehicles. Limited to a max alternator size of 150 amps or less per battery (link multiple batteries in parallel for alternators >150 Amps).

Reserve Capacity

340 minutes (RC25 @ 80°F)

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.

Internal Even-Heat Technology

Increases performance in extreme cold. When charging the battery in temperatures below 0°C/32°F DL’s internal heating element will warm the cells to 0°C/32°F. This increases the lifespan, performance, and efficiency of the battery.

Certifications

All DL 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, train, & marine transport.

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

Dual Purpose Use

Multi-purpose use as a deep cycle battery and/or as a starter battery for starting gasoline engines. Marine Outboards: Please refer to your manufacturer recommendations

Charger Recommended

12V 10A LiFePO4 charger is recommended (sold separately). 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.
