oldfruit Posted February 24, 2014 Share Posted February 24, 2014 I have this http://www.maplin.co.uk/p/maplin-jump-starter-digital-500a-150psi-compressor-n63nk that I use to power my NEQ6. If I were to run my mount, laptop with guide camera attached, plus I would have my DSLR connected as I have a 12 v dc adapter coming. I realise that I will need to double up on one of the sockets. Will the above power supply be good enough for a decent imaging session or do I need to look at something a bit more substantial? I only ask as I know some of you guys are able to estimate power usage for certain items and I have seen that you tend to recommend something with 17ah or more. The above power source is only 12 ah but it is all I have at the moment. Thanks, Mark. Link to comment Share on other sites More sharing options...
red dwalf Posted February 24, 2014 Share Posted February 24, 2014 (edited) i had a 17ah one and they dont last i`m affraid, don`t like the cold never seem to fully charge, and as soon as they go below 12v the mount plays up, i would go for a much better proper leisure battery and atach a 4 port cigar adapter to it for starters, some of the guys have all there rig including laptops running off these all night with no problems Edited February 24, 2014 by red dwalf Link to comment Share on other sites More sharing options...
Sheila Posted February 24, 2014 Share Posted February 24, 2014 nope no good at all, you would just about get set up I have 110 ah leisure battery and that is fine. I think some folks use slightly smaller but I like to be safe Sheila Link to comment Share on other sites More sharing options...
Guest Kheldar Posted February 24, 2014 Share Posted February 24, 2014 As above, that won't do diddly You need to be at 85Ah minimum IMHO Read the amp output on each of your power cables - that's the worst case (max) draw. Link to comment Share on other sites More sharing options...
glider Posted February 24, 2014 Share Posted February 24, 2014 I can just get away with a 40Ah Powering Power Pack from Halfords. I'd get the next size up 80Ah next time though. Link to comment Share on other sites More sharing options...
catman161 Posted February 24, 2014 Share Posted February 24, 2014 I use a 65ah Baz battery running 3 dew bands, mount and laptop. All housed in a fused battery box and it runs fine for a whole session. I have it on a constant trickle charge/discharge cycle when not in use. It's worth mentioning I only do simple planetary Astrophotography so it's not very intensive and tends to not be running continuously, more stop/starting when the patches of better seeing arise Link to comment Share on other sites More sharing options...
oldfruit Posted February 24, 2014 Author Share Posted February 24, 2014 It would seem that I have a jump starter for my car/van then. So I need to look into a leisure battery and doing some modifications myself. I have seen one or two useful threads on here where some of you guys and gals. Does Baz still do Baz`s batteries?
