When using Goto Telescopes, we strongly reccomend the use of an external power supply/ jump starter, or high energy lithium batteries. Regular Heavy Duty and Alkaline Batteries often do not supply enough current to power a telescope effectively, causing star alignment problems.
This range of Lithium Iron Disulfide (LiFeS2) batteries pack 5-6 times the capacity of their alkaline equivalents in high power applications. Using these represents a 40-60% cost saving over alkaline batteries.
Max constant load: 2000mA
