Using a detachable battery for shutter motor?

I don't have power to my Nexdome, everything is battery powered. Can the shutter be powered by a detachable lithium battery such as https://www.celestron.com/products/powertank-lithium-lt?_pos=4&_sid=9348f72ea&_ss=r . My dome is in my garden but 40m from any electric supply.

Actually I was more interested in whether the battery can be removed easily and recharged elsewhere, or a different battery used. I don't have electricity in my Nexdome and use Celestron Lithium batteries to power everything except my laptop (on its own battery).

Yes the battery can be removed, it's a PIA. After you remove the cover, 4-#4x1.5" SS screws, you can dismount the 12V7AH battery with a sharp putty knife to pry off the double-sided tape. After I cleaned my first battery, I applied industrial branded Velcro. I also purchased extra batteries to have as backup, there are other posts about dead batteries elsewhere, to make swapping/replacing them easier. One point I learned is Velcro is thicker than double-sided tape, so reattaching the cover is made a little more difficult.

Hope this helps.
