Re: powertank/battery to travel - mach1GTO

Do you also want to power other equipment (filter wheel, focuser, guider...) from this battery? Or is it just the mount?

Although Lithium batteries are light weight and powerful, they have some disadvantages. Most are not allowed on airplanes. They all require special chargers that are very expensive. A small sealed lead-acid battery for powering wheelchairs is really ideal and can be charged with inexpensive chargers which are available almost anywhere. The 18 amp hour Duracell measures 3" x 6" x7", weighs 12.5 lb and could even be used as a counterweight.

If this is too large, they make smaller ones of around 9 - 10 amp hours capacity which will run a mount for 18 - 20 hours.

You probably could, but thats really expensive for an 8.8Ah battery.  Look at Bioenno instead.  These have been great for me.  For under $200 you can get a 20Ah LiFePo battery that will last 2000 charge/discharge cycles, and it will literally put out about 90% or more of its rated capacity.

Plus these already are wired with a Powerpole connection that can be hooked directly to AP’s new Powerpole power cables.  This would probably easily last a couple nights out powering a Mach1.
Traveling by plane…100 watt/hour batteries are the limit I believe, and only in carry on luggage.  Probably not a good idea to try and travel by plane with these.

 Hi guys,
We are going to buy a Mach1GTO and we would like to get help with some topics:
. Do you think this Goal Zero battery SHERPA 100 POWER PACK handles the mach1cto for a night of work? If not, which suggestions do you have?

. Do you know if we could travel by airplane with batteries? (the technical support from Astro-physics said that could be a problem)
