Celestron PowerTank Lithium Pro

LiFePO4 Chemistry: 158.72 Wh Capacity and a 2000-Cycle Lifespan

At the core of the PowerTank Pro is a Lithium Iron Phosphate (LiFePO4) battery, a significant upgrade over older lead-acid and lithium-ion technologies. This chemistry provides a lifespan of up to 2000 charge cycles and can hold a charge for up to 10 years, eliminating the need for constant maintenance. Unlike sealed lead-acid batteries that degrade if not regularly topped off, the PowerTank Pro is ready when you are, whether it's for an impromptu observing session or as part of an emergency preparedness kit.

Quad-Output Connectivity: 5A Telescope Port, 10A Accessory Port, and Dual USB

The PowerTank Lithium Pro is built to run an entire imaging setup. The connection panel provides four distinct outputs to accommodate all your field equipment without compromise.

• 12V 5A Telescope Port: A dedicated, regulated output designed to power any Celestron computerized telescope via the included 6.5-foot power cord.
• 12V 10A Car Battery Port: This high-amperage output is essential for running power-intensive accessories like large dew heater strips, multiple cameras, or electronic filter wheels.
• Dual USB Ports: Keep your accessories charged with a standard 2100mA USB port and a second Quick Charge port for rapidly powering up modern smartphones or tablets.

All-Weather Reliability: IP-65 Rating and -4°F Operating Temperature

Designed for real-world observing conditions, the PowerTank Lithium Pro is sealed against the elements. Its IP-65 rating certifies it as completely dust-proof and resistant to water jets, so you can operate with confidence through falling dew or unexpected light showers. The LiFePO4 battery chemistry also maintains its output in extreme temperatures, with a certified operating range down to -4°F (-20°C), making it a reliable power source for winter deep-sky imaging.

FAA-Compliant Power: Under the 160Wh Carry-On Limit

Take your astronomy setup on the road. With a capacity of 158.72 Wh, the PowerTank Lithium Pro falls just under the 160 Wh limit set by the FAA for lithium batteries in carry-on luggage. This allows you to fly to remote dark-sky sites or eclipse destinations with a serious power source. An integrated dual-color LED panel with red and white light settings also serves as a convenient setup light or emergency flashlight.

PowerTank Lithium Pro vs. PowerTank Lithium: Double the Capacity for Demanding Setups

The PowerTank Lithium Pro directly addresses the needs of advanced users who found the original PowerTank Lithium insufficient for a full night of imaging.

• Capacity: The Pro model offers 158.72 Wh, more than double the capacity of the original PowerTank Lithium (84 Wh). This extra energy is critical for running dew heaters, cooled cameras, and other accessories alongside your mount.
• High-Current Output: While the original is perfect for powering a mount and charging a phone, the Pro's addition of a 10A high-current port is the key differentiator. It's designed specifically for the power draw of a complete astrophotography rig.
