With the PowerTank Lithium LT, Celestron is introducing a particularly light battery, which is especially suitable for smaller telescopes.
Modern telescope electronics react very sensitively to an incorrect voltage. Operating a telescope at too low a voltage can cause the motors to suffer at higher loads and even cause the electronics to fail. The PowerTank Lithium LT uses a built-in voltage regulator to ensure that it continually delivers at least 11.8 volts, until the battery is almost empty and shuts itself down.
Compared to a classic lead-acid battery, the PowerTank Lithium LT is smaller, lighter, more efficient and better for the environment. It offers better performance, a longer life and safer operation than other, cheaper lithium-ion batteries. It also offers automatic shutdown, reverse polarity protection and charge/discharge protection, as well as protection against overvoltage and short circuits.
We recommend the PowerTank Lithium LT for telescopes from the following series:
By the way: the battery also meets the current FAA regulations for hand luggage – ideal for travelling!
