• Energy

  1,620 Watt-hours (Wh)

• Weight

  42.92 lbs (19.47kg) so light that it floats. 1/4-1/2 the weight of a normal car battery.

• Lifecycles (battery lifespan)

  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.

• Operating temperature

  Ideal for rugged & harsh environments. Much better than SLA or other lithium batteries. -20°F min, +150°F max optimal operating temps (battery performs well down to -20°F). Internal even-heat technology allows for charging below 32°F. BMS high temp cut off at 167°F / 75°C.
