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”L x 9.3”W x 8.66”H (522mm x 238mm 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).

Suitable for:

  • Electric vehicles
  • Boating & Sailboat Batteries
  • Home energy storage
  • Solar storage
  • DIY Powerwalls
  • Emergency power
  • RVs
  • Golf Carts
  • Neighborhood Electric Vehicles (NEV)
  • Off grid energy storage

Experience the Dakota Lithium Difference

The 12V 200Ah battery is built with Dakota Lithium's legendary LiFePO4 cells. 3,000+ 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.
