Charging the battery
To charge the battery, use the supplied USB-C cable and adaptors to connect your
telescope to an electrical outlet. A power bank may also be used to charge your telescope.
(We recommend a USB 5V power bank.)
For an optimal battery charge, the maximum current used by the telescope is 2.4 A. Avoid
using a fast charger, which could fail to charge the battery as the charger might not be
detected.
The battery is estimated to last 2 to 10 years, depending on how often it is charged. A full
cycle equates to 10 charges of 90% to 100%.
Increasing the battery life
We do not recommend draining the battery (<20%).
Storing your telescope with a charge of 40% to 60% is essential for maximizing your battery
life. To avoid draining your battery completely, we recommend charging your battery at
least every 3 months. Keep your telescope away from light and moisture.
To increase your battery life, avoid using your telescope at low temperatures (<32°F) or
above 104°F, as this may cause damage. Very cold environments may increase battery
consumption.
