POWERBOX+ 135 WATERPROOF SOLAR GENERATOR, 12V 135AH DL+ 1,000CCA BATTERY INCLUDED
Experience the Dakota Lithium Difference
Inside the Powerbox+ 135 is the legendary Dakota Lithium Plus 12V 135 Ah dual purpose battery, built with our signature LiFePO4 cells. 2,000+ recharge cycles (roughly 5 year lifespan at daily use) vs. 500 for other lithium batteries or lead acid. Optimal performance down to minus 20 degrees Fahrenheit (for winter warriors). Plus twice the power of lead-acid batteries at half the weight.
SPECIFICATIONS
IP67 Waterproof rating means this battery is submersible at a depth of 3 ft of water for 30 hour with no internal moisture.
12% of mass above waterline. PB135 is a waterproof battery so light that it floats
Waterproof and submersible (IP67) ruggedized Powerbox+ 135 military spec plastic case with shock proof battery cradle
Waterproof automotive binder posts for connecting trolling motors, jumper cables, or other high power applications while maintaining waterproof seal
Waterproof voltmeter for monitoring the battery power level & external USB C & USB A for connecting devices while maintaining waterproof seal
300 watt continuous, 600 watt peak DC to AC Inverter w 2 AC wall plugs + 4 USB plugs and smart power use display
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
Dakota Lithium Plus 12V 135Ah Dual Purpose 1,000 CCA Battery 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.
World beating, best in class, eleven year manufacturer defect warranty.
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.
12.8 Volts (V)
Lithium battery equivalent to 1,000 Cold Cranking Amps (CCA) of lead acid battery engine starting power. Suitable for automotive applications.
11.6”x12.1”x 12.8” (295 x307x 325mm)
1,620 Watt-hours (Wh)
37.7 lbs (17.1 Kg). So light that it floats. 1/4-1/2 the weight of a normal car battery.
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.
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.
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.
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..
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.
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.
Contains a smart BMS temperature cutoff that prevents charging when cells are below 0°C/32°F and protects the battery.
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.
Multi-purpose use as a deep cycle battery and/or as a starter battery for starting gasoline engines.
Suitable for:
- STARTING CAR AND LIGHT TRUCK ENGINES
- DEEP CYCLE APPLICATIONS
- TROLLING MOTORS #FISHLONGER
- #OVERLAND & TRUCK BUILDS
- #VANLIFE & RV BATTERY UPGRADE
- CAR AUDIO
- WORKING REMOTELY
- EMERGENCY POWER & DISASTER RESPONSE
- CONSTRUCTION SITES
- MEDICAL DEVICES & CPAP MACHINES
- FISH FINDERS, FLASHERS, & BOATING ELECTRONICS
- MOBILE POWER STATION & SOLAR GENERATOR
- COMBINE WITH SOLAR PANELS FOR UNLIMITED OFF-GRID POWER
