A few years ago I was a very active amateur astronomer. I operated a somewhat elaborate CCD telescope system for astronomical imaging. The system included a go-to mount, CCD camera, and a laptop. I used batteries as the primary source of power for the system (no AC hookup in the desert).
I am now learning to become an RC pilot using an electric-powered trainer. It seems like a good time to use the great portable battery pack I originally purchased for the CCD system: I can use the pack to supply 12V DC whenever—and wherever—it is needed on the flight line.
I purchased the power pack at Kendrick Astro Instruments. Although I purchased the quad power pack, Kendrick also sells a dual pack. Here is the manufacturer's description of the packs:
“These batteries are for those who demand the most of a portable battery and want it to have high end features. The 2081 has 2 cigarette lighter jacks and the 2082 has 4, each one individually fused with a quality circuit breaker. There is an LCD display to indicate remaining voltage. Pressing the red button next to the display will give the state of charge of the battery.
The power jacks have permanently attached plastic caps that will flip closed to keep dirt out of the jacks when not in use.
The cordura carry bags have a couple of built in pockets to accommodate various battery accessories, such as cables or the charger.
These Power Packs have the muscle to meet the demands of the modern amateur astronomer / imager. They are rugged, beautifully made and dependable. With proper care they will last for 5 years or 500 charges, whichever comes first. A battery float charger is included with these batteries.
The included charger will never overcharge your battery and may be left plugged into the battery for extended periods of time without harming the battery.”
Horizon Hobby now offers a nifty 12V DC Power Adapter with Cigarette Plug that provides the perfect interface between the battery pack and my Li-Po charger.
