Field power

My new camera is completely dependent on computer and as it is cooled it draws more current than DSLR. My previous solution was a 18Ah jump start battery, which is already a in a bad shape. Computer alone eats the battery in half an hour. My goal is I give up before my battery does, so I had to do something. I decided to build a transportable battery using a quality 45Ah AGM battery, which has 45Ah capacity. This battery has enough capacity to power my equipment for 7-9 hours. Only downside is the weight: 14kg.
