About this product

Model:  cel_pwrtnk_lithium_18771
Part Number:  18771-CGL

New Lithium Phosphate (LiFePO4) portable power pack from Celestron designed to keep your telescopes, smartphones, tablets, GPS systems, cameras and other USB-powered devices powered and charged. The ideal outdoor portable-charging solution for your electronic gear.

FEATURES

  • Portable power pack for your computerised Celestron telescope using Lithium Iron Phosphate (LiFePO4) chemistry
  • Smaller, lighter, safer, and easier to maintain than lithium-ion and sealed lead acid designs
  • Up to 2000 charge cycles – four times more than lithium-ion & 7 times more than sealed lead-acid designs.
  • Un-recharged shelf life of up to 10 years – 3 times better than lithium-ion and 10 times better than sealed lead-acid designs
  • Environmentally friendly – Does not use toxic heavy metals
  • 86.4 Wh equivalent to approximately 7.2 Ah when running at 12v

The Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries.

  • The LiFePO4 has an un-recharged shelf life of 10 years compared to 3 years for the Lithium Ion and 6-9 months for a Sealed Lead-Acid battery.
  • The battery performance of the PowerTank Lithium degrades at a much slower pace than other chemistries.
  • The LiFePO4 can be charged and discharged 2000 times compared to only 500 for a Lithium Ion battery and 300 for sealed lead-acid designs.  
  • The batteries will last as long as the telescope you use it with!
  • The LiFePO4 uses phosphates instead of environmentally hazardous elements like cobalt or lead commonly found in other rechargeable batteries.
  • Can withstand higher temperatures than lithium-ion designs and will not be a fire danger if accidentally punctured.

This combined with it’s rugged design make it the perfect outdoor power supply.

Celestron Lithium 7.2 Ah LiFePO4 Powertank
14 December 2023  | 

Great battery. I'd been using an old motorcycle lead/acid battery that's been progressively loosing more and more of it's charging capacity. So this has been a revelation. I've used it a few times now powering an AZ-GTi mount, ASIAIR Plus, ASI2600 Duo and EAF. While these sessions have been limited to around three hours and the camera not cooled below -5° C (ambient wasn't far away from that anyway) it still had plenty of juice left even if I didn't!
Would recommend.

Power at your fingertips

As it says on the tin. With USB connections can charge or power other devices. The red and white lights have two brightness settings each. The lowest red setting could be a little dimmer though.

At 86WH it is any Airline hand luggage compliant.
18 October 2022  | 

Already have a couple of Tracers rated at 125WH, but certain airlines such as Air Mauritius don't automatically grant above 100WH. Bought 2 of these to avoid any risk from vexatious staff at Airline check-in. They performed flawlessly driving my trusty AZ-EQ5 GT mount. Havng 2 meant I could Park, Swap and Start from Park pretty seamlessly and carry on observing while recharging. Once again a flawless service performance from FLO. Spent a whole month on the Tropic of Capricorn with the VMC200L observing effectively overhead oppositions of the gas giants wearing shorts all night.

Celestron Lithium 7.2 Ah LiFePO4 Powertank
13 September 2022  | 

After investigating options for powering my HEQ5-Pro mount when observing away from home, I decided on this Celestron Powertank. Chris at First Light Optics responded very quickly to my questions, to confirm that it was compatible with the mount, and estimated it would give me 3 to 4 hours of operation. It arrived, well-packed, two days after I placed the order. The unit is slightly bigger than a pint glass, not very heavy and seems quite ruggedly built. I charged it and connected it to the mount, and initially thought it wasn't working. On reading the manual more closely, I saw that to start the device I had to press the power button twice in succession, not just once! Everything then worked perfectly, and I did a couple of tests to see how long the drive would operate before the battery discharged. Using only the RA motor, without any rapid slewing, the mount ran for over 9 hours. Obviously, if I did a lot of fast slewing between targets, the run time would be less, but I'm very happy with this performance. The red or white LED light panel on the side of the unit is a useful feature. The fixings for suspending the tank or attaching it to a tripod leg are usable but could be better. The USB charging ports can't be used while driving the mount, which may be an issue for some, and the remaining battery charge can't be tested while driving the mount, which is annoying. I haven't yet used the unit in the field, but based on my tests I think it will do everything I require. The lithium-iron-phosphate battery technology in the device is apparently capable of 2000 charge cycles, but mine won't reach that number for many years so I can't confirm it.

FLO yet again, speedy in response to questions on order, processed the order fast with efficient delivery. Looking forward to using this with new scope when it arrives. Thus far looks durable, sturdy, charged fine and all excellent as expected.

Fantastic powerpack
09 January 2021  | 

I absolutely love this powerpack- it straps to the tripod leg of my scope and the choice of red or white light in two brightness settings is very useful. It’s fantastic to be able to take my telescope anywhere without having to use batteries or plug it in. The powerpack is sturdy and not too heavy - just what I wanted. It arrived very quickly and well packaged - thank you FLO!

A weight off the mind...
28 September 2020  | 

This powertank was recommended by FLO for my Skywatcher 150i mount and scope. The mount will eat through 8 AA batteries quite quickly on a decent nights observing. However, this little beauty will power the thing for 10 hours from a charge. It's easy to use, attaches easily to the tripod leg or has a handy hanging capability. You can't go wrong with this, with it's built in LED lights (white and red) and bonus 2 USB ports to charge your devices. Spot on in every way.
