You kber 2 pcs. 60-80 AH marine batteries or deep cycle batteries. General car batteries can not tle fairly large discharge fr they take damage, therefore cigarette lighter fan marine or deep cycle batteries that can tle something hend of 30-50% discharge without taking too much damage. Deep / Marine batteries cost a lot more than normal. car batteries, but a good rule is, use the right TOOL for the job! The nvnte power-tank is fine enough for an evening of visual cigarette lighter fan astronomy, but when you also need voltage selection cigarette lighter fan for laptop, kamerare, dew-heater, etc. can not do the job. My setup as example 0.5 A to mount, 3.5 A for camera, 0.5 A to guide, 7.5A laptop additionally cigarette lighter fan div. filter wheel, red lighting, cigarette lighter fan heater, cigarette lighter fan etc. As you can see, a 17Ah power tank does not do the job, it will be totally drained in less than 2 hours and it can not withstand that kind of deep discharge cycles. If you use dew-heater will typpisk use between 1-3 A depending on how many varmebnd you use. Therefore, my worth, as mentioned at the beginning, a few good deep-cycle/marine batteries p 60-80 AH (ampere-hours) Edited by Tommy Andersen - April 17, 2012 at. 13:07
