Dakota Lithium 12V 1200 Ah 15 kWh LiFePO4 Solar Battery Bank


In stock

When you go off grid during a Dakota winter you need to be prepared for all that mother nature can throw at you. Built for high performance in rugged conditions, this off-the-grid solar battery bank combines 2 to 6 of our largest and most energy dense batteries into one big energy storage system.  Built out of Lithium Iron Phosphate (LiFePo4) technology this is a battery built to last. With a lifespan of 3,000 – 5,000 charge cycles this battery will last up to 5 times longer than your typical SLA battery – providing exceptional value over time. Optimized for solar energy storage, Dakota Lithium batteries provide a greater energy transfer efficiency, with double the usable power of lead acid or AGM battery banks. This means that 15 kWh of Dakota Lithium batteries provides the equivalent performance to 30 kWh of lead acid batteries — enough power for most off-grid homes and small businesses. Add a series wiring kit to build a 24v or 48V battery bank. Backed up by an 11 year warranty.


Bundle includes:

  • 2x, 4x, or 6x 200Ah Dakota Lithium batteries
  • 1-2x Dakota Lithium parallel wiring kit & fuse blocks
  • 1x 10A LiFePO4 charger per battery


What size battery bank Do I need?

  • 400Ah, 5 kWh system is optimal for mid sized RVs with air conditioning, or large RVs without AC, School bus builds, boats, tiny home, and cabins. For smaller RVs and boats, or camper vans we recommend this system.
  • 800Ah, 10 kWh system is optimal for larger boats, off shore sailing, small homes, and large RVs with air conditioning systems.
  • 1200Ah, 15 kWh system is optimal for DIY home solar, going off-the-grid houses, and large cabins.

Best in Class 11 Year Warranty. That is 10 years more warranty then most lead acid batteries.

Voltage and Capacity

Each battery is 12v 200Ah 2400Wh. LiFePO4 chemistry has a flat voltage curve, meaning this battery has twice as much usable capacity as a lead acid (SLA, AGM) battery with the same rating.

24V or 48V compatible

Add a series wiring kit to connect 2 or more batteries in series to make 24V or 4 or more batteries to make a 48V system.

Size & Weight

20.6” x 9.3” x 8.66” (522 x 238 x 220 mm). 59 lbs (26.7 kg) per battery

Storage Capacity

200 amp hours (Ah) at 12.8V


Up to 80% capacity for 3,000 -5,000 cycles in recommended conditions. (Typical SLA has 500 cycles)


200 A max continuous, 300 A max 10-second pulse. 9.0 V max discharge, 11.0 V max recommended discharge.


100 A max, Included is a LiFePO4 compatible charger. A SLA charger may work, but will reduce performance and lifespan of the battery.

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.

Safe & Reliable

Includes active BMS protection circuit that handles cell balancing, low voltage cutoff, high voltage cutoff, short circuit protection and high temperature protection for increased performance and longer life


M8 post bolts. (Max torque 15 ft. lbs.)

LiFePO4 Charger Included

Free 10 Amp (A) charger included. Dakota Lithium batteries like to 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. Upgrade to a 20 Amp charger for 2X faster charge time.

Parallel Wiring Connection Kit Included

Connection kit for wiring 4 batteries in parallel is included. Wiring kit includes fuses for redundant safety protection.

Lithium specific solar charge controller reccomended

Dakota Lithium iron phosphate batteries like to be charged at 14.4 volts, commonly knows as the “lithium setting” on solar charge controllers. We highly recommend a lithium compatible solar charge controller to increase the performance of your battery bank. Either choose the lithium setting on your existing controller, or upgrade to a lithium compatible version.

Lithium Chemistry

Lithium Iron Phosphate (LiFePO4).
