Storage Capacity

100Ah. Dakota Lithium batteries provide consistent power for all 100 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 lead acid batteries. You get all the juice down to the last drop.


5,120 Watt-hours (Wh). 5.1Kwh per battery. Stack 4 units in parallel for 20Kwh.




Up to 80% capacity for 5,000 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.

11 year warranty

Industry leading, best in class 11 year warranty.

Battery Size

27.3"L x 18.0"W x 7.84"H (695mm x 458mm x 200mm)

Shell Material

Cold Rolled Steel Shell. Very durable. Engineered for use in cabins, sheds, basements, garages, and other unheated spaces. Not marine grade waterproof. Not for use in golf carts.


Built in smart BMS with WiFi Remote Monitoring and Advanced MPPT Technology for charging via solar panels. WiFi Remote Monitoring allows for integration with smart home systems. Built in solar charge controller (MPPT) increases the efficiency of solar panels.

Max Continusous Charging Current

100A. Optimized for charging by solar or grid tie power with Advanced MPPT technology.

Max Continusous Discharge Current

100A. The flat discharge voltage curve provides a 75% bigger capacity than a 100Ah lead acid 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.

LCD Screen Design

Dynamic Display of System Data and Operating Status

Weather Resistance

Designed for use inside a sheltered space like a garage, shed, cabin, or basement. Not for outside use. For a waterproof marine battery see the 48V 105Ah battery. IP20.
