Jackery is also slightly expensive, and you can do the same thing (I've also got this) with a LiFe Po4 battery, and adapters to your mount. I bought the adapters from Jaycar for cheap. The battery cost $110.
LiFe Po4 is also a lithium battery (not the same as the Jackery) and will give you more recharge cycles than marine batterys, is MUCH lighter, easier to carry, smaller, and can discharge to a smaller capacity.
If you're new to this, I recommend staying away from the old tech, and embrace the new 
PM me if you want pictures of the battery setup, happy to show more if you want.
edit: forgot to add, Jackery is a regulated 12V lithium power bank. That means you will get 12V minimum (usually circa 13v) no matter the capacity. Other lithium batteries will drop voltage as you use the battery. For my mount (EQ6-R) a stable power supply is a must.
There is another power bank coming called the Bluetti AC50S (not to be confused with the older AC50) that is also regulated. It's out in the UK and US and Japan, but no local adapters yet. It will also charge faster than the Jackery, which is the Jackery's only main problem (mains charging peaks at 48W). I've been chasing the company to release an Aussie version, which they will do but they are slow. |
I’m also in the market for a good power solution for astronomy. I do have the celestron lithium 158Wh LifePro but I haven’t yet used it in anger but not convinced it will power everything. I have a Prima Luce Lab Eagle4S computer and the focuser, mount, dew straps and cooled camera will all plug in to that whilst the Eagle needs a good power source. I could use the Celestron just for the mount and the Jackery for everything else. Would it be sufficient?
I’m used to older deep cycle batteries telling me how many amp hours they provide but the Jackery doesn’t seem to say what it provides. What is it?
For a more powerful Australian option what do you think of this (except the price)?
