Lightweight battery - would this work?

[Helen]

I'm looking for a lightweight battery solution for travelling. This looks interesting - at the reduced price!

Do you think it would be enough to run a lightweight mount EQ3-2 type and a CCD? (maybe one battery pack for each!)

Thanks

Um, not sure it would Helen

If you are adding the EQ motors to the standard EQ3-2 mount, then this is 6v, not 12. So this pack would not do as it doesn't have a 6v output, that I can see at least.

I would think something like this: http://www.batterymasters.co.uk/Product-Ultramax-NP12-12,-12V-12Ah-Sealed-Lead-Acid-Rechargeable-Battery-(L(mm)-W(mm)-H(mm)-151-98-97.5)_1380.aspx would be better for the camera and this http://www.batterymasters.co.uk/Product-Ultramax-NP10-6,-6V-10Ah-Sealed-Lead-Acid-Battery-(L(mm)-W(mm)-H(mm)-151-50-97.5)_1378.aspx for the mount?

?

not exactly light weight but it would do away with the counterweight

Have you thought about using a small motorcycle battery, say 6volt 8 amp hour

If your travels include flights then there are restrictions on the types of battery you can take with you...

You need to be careful not to over discharge Lithium battery. They tend to explode if discharged too quickly.

That Ankier battery looks like it's designed for small gadgets with a low current draw so it may not be suitable for GOTO and CCD. External batteries designed to power laptop would be a better bet. e.g. This one is roughly equivalent to a 12V 7Ah with a 3.5A output http://www.amazon.co.uk/Energizer-XP18000-Universal-Rechargeable-External/dp/tech-data/B002K8M9HC/ref=de_a_smtd

I used one to power my laptop and QHY5v when I imaged the Venus Transit abroad last year. It lasted about 4 hours before running out and then my laptop switched to its internal battery for the remainder of the transit. (the mount was a simple single axis drive powered by 8 AAs)

The Anker battery pack is a fantastic bit of kit, I have two of them, does 5v 9v or 12v and will charge a phone or tablet (fully charges my Nexus 7 twice before needing to be recharged itself). It will certainly power your CCD but I'm not sure it would drive a mount for long and it's a bit expensive to buy on the off chance for that.

Thanks everyone :-)
