Battery pack advice.

[prasadka]

Hello,

I've rung up Maplins and Halfords, they dont seem to do a 12v/cigarette lighter type of battery pack- they do one that powers of the mains though. May I have some suggestions for a battery pack please, that I can use to power a sync scan goto. I know that a celestron battery pack is available at about 80 quid- I am looking at cheaper options.

Cheers,

Prasad

Hi Karlo,

The first link was what I was after. The last one was the one that i'd found, but was not sure if that would indeed suit my current requirement. I was after something that I can carry after charging it for some time at home.

Regards,

Prasad

This one should do. It works with both my 102 SLT and CG5-GT anyway.

7Ah is a little small to run a a mount and dew heaters all night (and lets be honest the first clear dark dry night we get, we will be out all night now its winter )

I have two of the 17Ah battery packs from Maplins (one for mount, one for dew heaters) and a 7Ah Celestron one.... the only one that ever ran out of power was the 7Ah one at Kelling, Spring, 2007... anyone remember how bad the dew was on the Saturday? I killed the 7Ah in 3 hours...

I think I severely dented my 17Ah using a hairdryer so much that night!

I second Steve's comments re the 7Ah - its not really enough especially if you remember that most batteries don't appreciate being drained below 50% and if its cold the batteries performance will be hit...
