JUICEBOX 100
Get the elite, heavy-duty performance of a professional dual-battery system with the ultimate convenience of a self-contained, drop-in box.
The Juicebox 100 packs your secondary power source, charger, and monitoring system into one ultra-rugged, portable package. Engineered for those who operate where failure is not an option—from tactical SWAT units and remote hunters to tournament anglers and overlanders—this system delivers high-end 12V capability without requiring a permanent vehicle build.
Simply drop it in, bolt it down using the included heavy-duty mounting brackets, and link it to your alternator or solar setup. You instantly have a premium power station that charges while you drive, moves seamlessly between vehicles, and keeps your mission running for days.
NOTE: The battery will ship separately. Please watch our quick setup guide video to see how to easily connect your battery.
DUAL BATTERY POWERHOUSE INTERNALS
We partnered with the gold standards of the automotive, marine, and off-road engineering worlds to ensure maximum reliability.
Take a look at what the JUICEBOX100 is packed with inside...
100aH Dakota Lithium Battery
The beating heart of the system. It delivers safe, stable LiFePO4 power with double the runtime of traditional AGM setups and a fraction of the weight.
REDARC Alpha25 BCDC Charger
The gold standard in DC-to-DC charging. It pulls up to 25A directly from your vehicle's alternator while you drive, features built-in Green Power Priority™ MPPT solar regulation, and can even jump-start your vehicle's dead starting battery via the REDARC app.
REDARC Smart Shunt
Pinpoint accuracy for your power tracking. It connects straight to your smartphone via Bluetooth to tell you exactly how much juice you're drawing and how much time you have left at camp.
Pre-wired Bus Bars

Dedicated Solar Port
Plug portable or roof-mounted solar panels directly into the built-in Anderson-style port. With REDARC’s Green Power Priority™, the system automatically prioritizes free solar energy to lighten the load on your alternator.
12V and USB
2x Marine-Grade 12V Outlets: Heavy-duty, locked-in power perfect for 12V portable fridges, diesel heaters, or other field equipment.
1x Dual Fast-Charging USB Socket: Features both USB-A and high-speed USB-C output to keep phones, tablets, thermal optics, and laptops topped up.
BUILT DIFFERENTLY
Most "power boxes" on the market are sealed, disposable plastic blocks. If a single port fails, a fuse blows deep inside, or you want to upgrade a component, you have to throw the whole thing away.
Not the Juicebox100. We believe in gear that lasts a lifetime.
How It Works
Explanation of how the JUICEBOX100 is charged.
The heavy duty Smart Battery Combiner device is rated to handle 300 amps continuously flowing through it. It can handle higher amperage loads for shorter durations - 500 amps for 5 minutes, and up to 2,000 amps for 5 seconds. The combiner requires a minimum of 8 volts to operate. It does not consume any power to keep the batteries connected together, and it does not generate any heat.
The Positive and Negative bus bars have 3 different size studs - - 3/8", 5/16", and 1/4" diameter for heavy cables for a winch, air compressor, fuse box, etc, and three #10 screws for attaching smaller ring terminals for your low amp accessories such as small LED lights.
Our battery cables are made with 2ga heavy duty, high strand count, pure copper welding cable. Why welding cable instead of battery cable? It's more flexible, more conductive, with a thicker, more abrasion resistant jacket for ultimate durability. The lugs are made of pure copper and tin plated which is more conductive and eliminates corrosion, then covered with an extra thick, adhesive-lined heat shrink material to fully seal the ends of the copper wire for long lasting performance.
If you're handy with a wrench, and if you follow along with our detailed installation video, most people can install this kit in their driveway in 2-3 hours. If you prefer to have your local 4x4 shop install it for you, most shops will bill 2 hours for installation in a stock vehicle. If you already have some aftermarket wiring that needs to be rerouted to our bus bars or otherwise cleaned up, add to the installation time as appropriate.

How can I hook up solar panels?
The integrated Redarc Alpha charger has an integrated MPPT solar charger controller built in. No additional charge controller device is required. The Juicebox100 includes a 50 amp Anderson plug for connecting directly to your solar panels. If your brand of solar panels come with a different connector such as MC4 connectors, you will need an adapter to plug them into the Anderson plug.
I left my headlights/radio/dome lights turned on, and now the engine won't crank. I thought the system would turn off the cranking battery to protect it from getting too low.
Please keep in mind that your factory fuse box gets its power directly from your cranking battery all the time. The Juicebox100 does not link the batteries together in parallel like the GEN3 system does. With the integrated the Alpha charger, you can use its 'Start Recovery Mode' feature which will charge up your cranking battery by powering the Alpha charger from the accessory battery for 15 minutes to help get the cranking battery recharged enough to start the engine.
Do I need an accessory fuse box or is it unnecessary since the kit has the power and ground bus bars for hooking up my accessories?
The sPOD or similar devices are a great compliment to our dual battery systems. They allows you to easilyy add electrical accessories that need a fuse, relay, and a switch. Our bus bars are perfect for connecting accessories that need direct battery power, or for those that come with a wire harness that includes a fuse, relay, and switch.
How do I connect an sPOD system to the dual battery kit?
The sPOD source unit should be connected directly to our power and ground bus bars. This way, anything that you are controlling through the sPOD will get power from the aux battery, and will not drain down your cranking battery.
My factory post clamps won't get tight enough on the battery post. It is loose and causing weird electrical issues.
Most factory battery post clamps are made of light duty stamped sheetmetal, and stretch or wear out over time. First, make sure the post clamp is fully seated all the way to the bottom of the battery post. Try loosing up the post clamp nut so it is very loose, then use a large socket and gently tap the clamp down onto the post. Now tighten the clamp nut and see if it is secure. You can also try using a battery post shim, available from your local auto parts store, to fill the gap between the clamp and the post, allowing the clamp to tighten down more securely.
