CHARGES YOUR 12V BATTERY ON THE GO

  • 200% TWICE THE POWER OF TRADITIONAL BATTERIES
  • 1/2 HALF THE WEIGHT
  • 5x CHARGES 5 X FASTER
  • 4x LASTS 4 X AS LONG
  • 100% SAFE & RELIABLE

This lightweight, affordable, and easy-to-install 12 V solar panel is expertly built and very user-friendly. When in full sun one panel will fully charge your Powerbox 10 or 10 Amp Hour (Ah) battery in 7-9 hours or a half charge in 3-4. Two panels will charge twice as fast. Built with marine grade easy flex technology, this solar panel is waterproof, flexible, and can glue to be fixed to any surface, Panel comes with a 4 ft wiring kit with alligator clips pre-installed. Easily connects to any 12v battery. Use multiple panels to increase charging time or for charging bigger capacity batteries.

Fishing pro staff tip – this is the perfect size solar panel for trickle charging batteries for fish finders, and small trolling motor batteries (<50Ah). Install on your boat trailer and park in the sun, by the weekend your electronics will be charged up and ready to go.

For larger systems such as RVs, Boats, or small cabins we recommend the 100 watt solar panels and a lithium compatible solar charge controller.

Suitable for:

  • CHARGING 12V BATTERIES ON THE GO
  • WEEKEND WARRIORS - INSTALL ON YOUR TRAILER TO TRICKLE CHARGE BOAT BATTERIES DURING THE WEEK
  • CHARGE YOUR POWERBOX WHILE OFF GRID
  • CAMPING, HIKING, BOATING
  • TRAIL CAMERAS
  • EMERGENCY KITS FOR AMATEUR RADIO
  • ANY SMALL OFF-GRID POWER SYSTEMS

Frequently Asked Questions


Twice the Power?

Yes! Here at Dakota Lithium we build all of our batteries with lithium iron phosphate technology which has many distinct advantages over traditional batteries. Including 60% less weight, a charging speed that is up to 5X faster, and a significantly longer lifespan (5-10 years longer on average). One of the most noticeable advantages however is the flat voltage curve. Unlike a lead acid battery where the voltage drops as you use the battery a Dakota Lithium battery has a steady voltage for 99% of the battery's charge. That means you get all the power down to the last drop and double the usable power of traditional batteries.

Are Lithium Batteries Safe?

Dakota Lithium batteries are 100% safe & reliable. Our signature chemistry, Lithium Iron Phosphate (LiFePO4), does not contain rare earth elements (like Cobalt) or heavy metals, is non-toxic, including no lead or acid, is non-corrosive, does not off gas, requires no watering or maintenance, can be placed in any orientation, and unlike other lithium batteries will not explode or catch fire. In addition, each Dakota Lithium battery is protected from over heating, over charging, and short circuiting, by a battery management system (BMS) microchip that also extends the lifespan and is contained in a rugged, waterproof case (although enough water can conduct electricity between the terminals, so don't submerse the battery). For best performance & reliability we recommend using a LiFePO4 charger.

How do I charge a lithium battery?

Dakota Lithium batteries perform best when charged by a lithium compatible charger. Lead acid or SLA chargers, on-board chargers for AGM batteries, or other non-lithium chargers will charge a Dakota Lithium battery but only to 70-80% of capacity. This is because Dakota Lithium iron phosphate (LiFePO4) technology charges and is full at a higher voltage then traditional batteries (Dakota Lithium charges at 14.4 Volts). Chargers with a lithium battery setting or designed for lithium will charge at the appropriate voltage. See our full catalog of LiFePO4 battery chargers here. All batteries 54Ah and larger include a free LiFePO4 compatible charger. For troubleshooting tips download the Dakota Lithium battery user manual here.

Will cold weather affect my battery?

Your Dakota Lithium battery will discharge normally between a range of -20F and 120F (-29C to 49C). DL batteries are commonly used among ice fishers for their flashers and ice augers, so they are quite resilient and are frequently used in cold climates. In cases of extreme cold however, it is recommended that the batteries be insulated. We also do not recommend charging our batteries below freezing temperatures. If you are planning to regularly charge your battery below freezing temperatures we recommend the DL+ 12V 135Ah battery which has an internal heating element and is optimal for use in cars, trucks, RVs, off grid solar, and any application where the battery will be charged regularly in extremely cold environments (like a North Dakota winter).

Can I use this to start my car/boat engine?

Our DL+ line of batteries have 1000cca of engine starting power plus the same legendary deep cycle capabilities of all Dakota Lithium batteries. That means you can use them for starting a boat, car or truck engine. Our standard deep cycle batteries do not have this cold cranking ability and can not be used for a starting battery.

What Trolling Motor Battery Do You Recommend?

"Dakota Lithium is a proud sponsor of over 200+ professional athletes in the fishing industry. Here's batteries sizes recommended by our pros depending on the size of your trolling motor: Motor Thrust / Max Amp Draw (A) @ Voltage (V) / Recommended Battery 20 lbs / 20A @ 12V / DL 54 or DL+ 60 25 lbs / 25A @ 12V / DL 54 or DL+ 60 30 lb / 30A @ 12V / DL 54 or DL+ 60 or DL 100 45 lb / 42A @ 12V / DL 54 or DL+ 60 or DL 100 55 lb / 50A @ 12V / DL 54 or DL+ 60 or DL 100 70 lb / 42A @ 24V / 24V Single or DL 54 x 2 or DL+ 60 x 2 or DL 100 x 2 80 lb / 56A @ 24V / DL+ 60 x 2 or DL 100 x 2 or DL 200 x 2 101 lb / 46A @ 36V / 36V Single or DL+ 60 x 3 DL 100 x 3 or DL 200 x 3 112 lb / 52A @ 36V / 36V Single or DL+ 60 x 3 or DL 100 x 3 or DL 200 x 3 >112 lb / Up to 100A @ 36V / DL+ 60 x 3 or DL 100 x 3 or DL 200 x 3 For wiring multiple batteries in series we recommend Connect Ease trolling motor connection kits available on our trolling motor battery page. For a deep dive on trolling motor batteries read How to Choose A Lithium Battery for Trolling Motors"

What battery do I need for my RV or Camper Van?

The industry standard house battery size used in most RVs, Campers, and #VanLife builds is the DL 100Ah battery. This is a drop in replacement for AGM and most lead acid batteries. If you are charging off your engine's alternator we recommend a Victron DC-DC smart charger. If charging off solar panels we recommend a Victron Smart Solar charge controller, or if you have a solar charge controller choose the lithium setting. A handy size chart for number of batteries needed by size of RV is available here.
