Terminals & Binder Posts

Waterproof automotive binder posts for connecting trolling motors, jumper cables, or other high power applications while maintaining waterproof seal

Voltmeter & External USB plugs

Waterproof voltmeter for monitoring the battery power level & external USB C & USB A for connecting devices while maintaining waterproof seal

DC to AC Inverter Included

300 continuous, 600 watt peak DC to AC Inverter w 2 AC wall plugs + 4 USB plugs and smart power use display

Internal Storage & Anti-Static Electronics Tray

Internal ballistic nylon bag with 3 zippered pockets for waterproof storage of personal electronics when box is sealed plus a removable, washable, anti-static silicone electronics tray for keeping personal electronics clean and safe while charging included

Battery Included

Dakota Lithium Plus 12V 135Ah Dual Purpose 1,000 CCA Battery included

Charger Included

10A LiFePO4 charger included

11 Year Battery Warranty

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

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

12.8 Volts (V)

Engine Starting Power

Lithium battery equivalent to 1,000 Cold Cranking Amps (CCA) of lead acid battery engine starting power. Suitable for automotive applications.

Size

11.6”L x 12.1” W x 12.8” H (295mm x 307mm x 325mm)

Energy

1,728 Watt-hours (Wh)

Weight

37.7 lbs (17.1 Kg). So light that it floats. 1/4-1/2 the weight of a normal car battery.

Lifecycles (battery lifespan)

Up to 80% capacity for 2,000 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. Internal heating allows for charging in temps down to -20F

Discharge

100 A max continuous discharge, 750A max 2 second pulse, 650A max 5 sec pulse. The flat discharge voltage curve provides a 75% bigger capacity than a 60Ah SLA battery.

Ultra-Fast Charging

DL rapid charge technology allows for charging speeds of 60 minutes (135 Amps). Recommend for longest life 60A or less (1C), Max continuous 80A (1.5C). 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.

Internal Heating for Winter Use

Includes internal heating technology that allows for charging in temperatures down to -20F

Cold temperature charging protection

Contains a smart BMS temperature cutoff that prevents charging when cells are below 0'C/32'F 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.

Dual Purpose Use

Multi-purpose use as a deep cycle battery and/or as a starter battery for starting gasoline engines.
