iOptron Lithium-Poly Battery for SkyHunter 3709

Replacement Lithium-Poly (Lipo) rechargeable battery for iOptron SkyHunter mount.

If you're heading off the grid with your SkyHunter mount, the iOptron Lithium-Poly Battery (#3709) ensures your tracking session stays powered from dusk until dawn. This compact, rechargeable battery was designed specifically to fit seamlessly into the SkyHunter mount's integrated power compartment—no dangling external battery packs or cable tangles to worry about.

Field-Ready Power for Your SkyHunter

The #3709 battery is a rechargeable lithium-polymer power source engineered to deliver consistent voltage and long runtimes. When fully charged, it provides up to 10 hours of operation, depending on your tracking load and environmental conditions. That’s enough to cover a full night of astrophotography or visual observing without plugging into external power banks or AC sources.

Its slim profile and lightweight design allow it to remain installed within the mount during use and travel, keeping your gear streamlined and easy to set up. It's the ideal backup or replacement for the factory-installed battery—especially if you're planning extended sessions away from power outlets.

Safe, Reliable, and Easy to Charge

Built-in overcharge and discharge protection circuitry keeps your battery safe over repeated cycles. Charging is as easy as connecting to a standard 5V USB source using the appropriate charging cable (sold separately). A status LED on the SkyHunter mount will indicate battery level and charging state.
