Power Supplies
Good morning all;
I'm chasing after some thoughts on power supplies. As someone who is starting out into astrophotography after years as a visual observer, I'm looking for recommendations as to the best power supply for a HEQ5 pro mount.
It's got to be reasonably portable - I have a good (Bortle 4) site a short drive away with no obstructions, so something I can pack into a car and then carry a short distance would be fantastic.
I've been looking at the BLUETTI stuff, but don't know too much about it, i.e., will it provide the right power for the mount.
Certainly no genius at this, so any advice will be welcomed.
Cheers!

There was a fairly long thread on portable power supplies recently, but I am having trouble finding it at the moment.
Can anyone else remember it?

I was in the same quandary, hence the question...
Thanks for the responses folks. The Bluetti gear is looking strong, I just want to check all of the possible options before I make the leap.
Another thought - as I type, it's about 2 degrees outside. How resilient are the Bluetti units in the cold?

I've run mine in the cold no issues.

I've just been pointed to these guys in another forum I hang out in. They look to be a bit on the pricey side, but the larger units boast some serious battery capacity.

Hi
Just wandered off to look myself. I like the look of the table as well. Seems like a good idea.

For what it's worth, Bluetti are having a sale at the moment.

Yep. I've taken advantage of that...
Folks, my thanks for the advice. I've ordered one of the smaller Bluetti units, although I have to admit I do like the look of the Gosun units that were suggested as well.
Cheers for all of the advice, it's much appreciated.

Cool! When you do have a chance to put it through it's paces, do you mind doing a review of it?

I could probably be talked into that. When it arrives, I'll charge it up, and see what it can do before I put pen to paper (or fingers to keyboard...)

Nice. I'm sure you'll love it. I got the EB70, and it's great.

The Gosun (I think) use Lithium cobalt. Not all lithiums are the same. They're not LiFePO4 though, and that's what matters.
LiFePO4 is safer, has more charge/discharge support, and keeps voltage basically until emtpy.
That's why the Bluetti's are great.
