Engineered with Lithium Iron Phosphate (LiFePO4) technology this battery has twice the power, half the weight, and lasts 4 times longer than a lead acid battery - providing exceptional lifetime value. Built for dual purpose performance the DL+ provides 1,000 cold cranking amps (CCA) and a high continuous discharge rate, making it a great choice for high amp draw applications like starting engines, car audio, heavy machinery, golf carts, or any electronics that require a lot of power at one time. In addition, the DL+ provides the same legendary deep cycle marine performance that Dakota Lithium batteries are known for, giving you lots of power for a long time. This is the most versatile Dakota Lithium battery, with the ability to both start engines, and power electronics. LiFePO4 charger included. Backed up by an 11 year warranty.
Waterproof Rating
IP67 Waterproof rating means this battery is submersible at a depth of 3 ft of water for 30 hour with no internal moisture.
Buoyancy (how well it floats)
12% of mass above waterline. PB135 is a waterproof battery so light that it floats
Powerbox+ 135 Case
Waterproof and submersible (IP67) ruggedized Powerbox+ 135 military spec plastic case with shock proof battery cradle. Fully field maintainable -- easy to disassemble and repair in the field if needed.
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 watt 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. Complementary Jumper Cables Included
Charger Included
12V 10A LiFePO4 charger included. 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.
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 x12.1”W x 12.8”H (295mm x 307mm x 325mm)
Energy
1,620 Watt-hours (Wh)
Weight
42.92lbs (19.47kg) so light that it floats. 1/4-1/2 the weight of a normal car battery.
Lifecycles (battery lifespan)
Up to 80% capacity for 5,000 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). Internal even-heat technology allows for charging below 32°F. BMS high temp cut off at 167°F / 75°C.
Discharge
100A 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). 14.4V 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..
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
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.
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 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.
Dual Purpose Use
Multi-purpose use as a deep cycle battery and/or as a starter battery for starting gasoline engines.
