Our lithium-ion batteries are made of high-quality Samsung cells. Maintain at least 25% of the battery's capacity when not in use. If left uncharged the battery will go into the deep discharge and won’t turn on.
NOTE: Our single and dual temperature controllers are not compatible with these portable batteries because they already have a built-in temperature controller.
