Specifications

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
2000 watt continuous, 4000 watt peak DC to AC Inverter w 2 AC wall plugs + 2 USB-C PD60W 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

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
35A max continuous discharge, 1000A max 2 second pulse, 900A max 5 sec pulse. 9.0V Max discharge, 11.0V Max recommended discharge.The flat discharge voltage curve provides a 75% bigger capacity than a 135Ah SLA battery with the same CCA rating.

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. Recommended Charger 12V 10 A LiFePO

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.
