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

    This direct-replacement Lithium-Polymer battery holds 2000 mAh of capacity at a nominal 3.7V output, peaking at 4.2V when fully charged. Weighing just 1.1 oz (32g) and measuring 8.5 x 34 x 51 mm, it is engineered to be a precise power source and physical fit for specific iOptron portable tracking mounts.

    2000 mAh Capacity and 3.7V Output for All-Night Tracking

    With a 2000 mAh capacity, this battery supports a full night of wide-field astrophotography, running your tracker for hours on a single charge. The regulated 3.7V output ensures consistent motor speed for reliable tracking, which is critical for avoiding star trails in long exposures. Lithium-Polymer chemistry results in a high power-to-weight ratio, keeping your portable setup light.

    A 51mm x 34mm x 8.5mm Replacement for iOptron Mounts

    This battery is the specified replacement for the internal power source of the iOptron SkyGuider Pro and SkyTracker Pro mounts. Its precise dimensions of 51 x 34 x 8.5 mm ensure it fits correctly within the tracker's internal battery compartment without modification. At only 32g (1.1 oz), it adds negligible weight to your travel imaging rig.

  • How long can I expect this 2000 mAh battery to power my iOptron SkyGuider Pro for an imaging session?

    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.

    Will this 3.7V battery provide enough power for my SkyTracker Pro when it's cold outside?

    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.

    Is this Lithium-Poly battery a direct fit for the iOptron SkyGuider Pro?

    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.

    What is the correct charging voltage for this 3.7V Lithium-Poly battery?

    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.

    Why is the peak voltage of this battery 4.2V if it's rated for 3.7V?

    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.

    What precautions should I take with this Lithium-Poly battery?

    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.
