Celestron Power tank 12V 3AH Li-Iron

Lithium-phosphate battery. The power tank supplies your telescope with power in the field. It is smaller, lighter and safer than lead or lithium batteries. You can also charge tablets or smartphones via the USB outputs; red and white LEDs help when setting up and dismantling. Up to 20000 charging cycles - four times more than lithium-ion batteries and seven times more than lead-acid batteries - always ready for use. Environmentally friendly - without toxic heavy metals. This model does not work with the Sky-Watcher EQ6 telescopes. A safety circuit is built into the Powertank Lithium, which automatically switches off the battery after approx. one hour if the battery does not detect a current consumption of at least 250mA.
