Storage Capacity

200 ampere hours (Ah). Dakota Lithium batteries provide consistent power for all 200 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.




2,560 Watt-hours (Wh)


F12 terminals (posts that screw in) with M8 size bolts. Easy to adapt to different connection needs. (Max torque 15 ft. lbs.)


20.6” x 9.3” x 8.66” (522 x 238 x 220 mm) per battery.


59 lbs (26.7 kg) per battery. That's 60% lighter than a SLA battery.

Lifecycles (battery lifespan)

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.

Operating temperature

Ideal for rugged & harsh environments. Much better than SLA or other lithium’s. -20'F min, +120'F max optimal operating temps (battery performs well down to -20'F). Avoid charging below 32'F.


200 A max continuous, 400 A max pulse 10 second pulse. The flat discharge voltage curve provides a 75% bigger capacity then a SLA 100Ah battery.


50 A max, 14 V max recommended, 15 V max. Included is a LiFePO4 compatible charger. A SLA charger may work, but will reduce performance and lifespan of the battery.

Includes active BMS protection

Contains a circuit that handles cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection and high temperature protection for increased performance and longer life.

Wall Charger Included

1-3X 10A LiFePO4 charger included (1 per battery)

NOT for Starting Engines

This is a deep cycle 12v battery. Not designed for starting gasoline engines.


The Smart Solar series from Victron also includes Bluetooth smart monitoring, or with the GX series of monitoring equipment, a user can set charging parameter and battery type (choose the lithium setting for DL batteries), and monitor and record solar yields.


The Victron BMV Smart Battery Monitor is a powerful battery monitor with Bluetooth on board for remote monitoring, and an easy to use screen for manual data.

VICTRON MULTIPLUS C 12/2000/80-50 120V INVERTER & CHARGER included

The MultiPlus is a combined inverter and charger in one elegant package. Due to its versatility, programmable settings, and rich features we have found the Multiplus to be the ultimate in off grid micro-functionality – like vans, RVs, boats, and off-grid homes. Its many features include a true sine wave inverter, adaptive charging, hybrid PowerAssist technology, plus multiple system integration features. The unique power assist allows for safe charging using generators, shore power, or other power sources and the uninterrupted energy supply (UPS) function means no downtime in the case of power disruption (it seamlessly transitions to battery power). The 2,000 watt inverter allow you to use 12V Dakota Lithium batteries to power household electronics that require 120V AC (the wall plug in your home) and is a good size to run a medium sized TV, stereo, fridge, small kitchen appliances, computers, or other home electronics.


a recommended add on for the Multiplus, since it allows you to install the Multiplus out of sight, and use this control panel to manage the settings of your Multiplus inverter and charger.

Suitable for:

  • Off Grid Electrical Systems
  • Recreational Vehicles
  • Solar Energy Storage
  • #VanLife & Van Builds
  • Boats & Cruising
  • Home Solar & Power Walls
  • Marine Applications
  • RV Camper Trailers
  • Off-Grid Cabins & Tiny Homes
  • Deep Cycle Applications Only. Not for starting gasoline engines

Experience the Dakota Lithium Difference

The DL 200Ah battery is built with Dakota Lithium's legendary 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.
