iOptron Lithium-Polymer Battery (3.7V, 2000 mAh)

While exact runtime depends on factors like payload balance and ambient temperature, a fully charged 2000 mAh battery will typically power an iOptron SkyGuider Pro for a full night of imaging, often lasting 6-8 hours or more under normal conditions.

Yes, but like all lithium-based batteries, performance will be reduced in cold weather. The 3.7V output is stable, but the total available capacity (runtime) will decrease as temperatures drop. For very cold nights, it is advisable to keep the battery as warm as possible or have a fully charged spare.

Yes. This battery is designed with dimensions of 51 x 34 x 8.5 mm to be a direct, drop-in replacement for the original battery in both the iOptron SkyGuider Pro and the SkyTracker Pro, requiring no modification to the mount's battery compartment.

The charging voltage should not exceed 4.2V. Most chargers designed for single-cell (1S) Li-Po batteries will correctly charge to this peak voltage. The mount's internal charging circuit is designed for this specification.

3.7V is the nominal, or average, operating voltage of the battery cell during its discharge cycle. 4.2V is the maximum voltage when the battery is 100% charged, and it will gradually drop to around 3.0V when fully discharged. The 3.7V rating represents its typical working voltage.

Lithium-Polymer batteries offer excellent power density but require care. Avoid puncturing, crushing, over-charging beyond 4.2V, or fully discharging the battery, as this can cause permanent damage and pose a safety risk. Always use a charger specifically designed for Li-Po cells, such as the one built into the iOptron mount.
