High Temperature Tolerance Test:
The battery cells in the Spartan Power SP-JS20K JumpStarter are manufactured by a factory with over 13 years experience producing LiPo batteries, and the only supplier whose battery cells go through 149F high temperature test in a vacuum environment a week before assembling. Those battery cells from manufacturers that do not go through high temperature tolerance testing will have a high rate of swelling and burning.
