Description
Powerbox 135 Shell Only
Turn your lithium battery into a rugged, waterproof mobile power station.
The Powerbox 135 Shell is designed for customers who already own a compatible Dakota Lithium battery and want to add the protection, portability, and utility of the Powerbox system. This kit includes the rugged waterproof case, USB charging ports, 2000W inverter, internal storage pouch, electronics tray, voltmeter, and external connection points — giving you a cleaner, more capable way to carry, protect, and use your battery in the field.
This is the shell only. Battery is not included.
The Powerbox 135 Shell is designed to fit the Dakota Lithium DL+ 12V 135Ah battery, but it can also accommodate other compatible batteries such as the DL+ 12V 135Ah, 12V 54Ah, and similar form factors. If you use a battery smaller than the DL+ 12V 60Ah, additional foam or padding may be needed to keep the battery secure during transport and use.
Built for harsh marine, camping, overland, emergency, and off-grid environments, this waterproof case lets you upgrade your existing lithium battery with more utility. Power small devices through USB ports, run AC-powered gear through the 2000W inverter, monitor battery level with the voltmeter, and keep essentials protected in the internal storage pouch.
It’s the perfect add-on for turning your Dakota Lithium battery into a field-ready power solution.
