[QUOTE="poeee, post: 57100, member: 2388"] For those using electric, have you thought about using 'hobby' LiPo batteries? I race onroad radio control cars, and am set up with chargers and gear, and after reading this thread about people lugging around car batteries, I thought this might be something to investigate. For eg, you can buy an 3 cell (11.1v, but 12.6v at full charge) 8000mAh LiPo for around $50 from a local warehouse shipped to your door. This would, in theory, power a pump drawing 4 Amps for two hours. A pack I'm using as an example weighs [b]640 grams[/b]. There are other things you have to consider, however. They need a special charger. A 10A charger I use for racing costs about $35 (you would charge at 1C - 8A for an 8000mAh battery). The charger would run off 12v, so you need some kind of beefy power supply if charging from mains power (I use an old xbox power supply). LiPo's aren't the safest battery chemistry. You have to make sure you don't over charge them (the charger takes care of that) and have to have a low voltage cutoff so you don't over discharge them. LiFe batteries are safer, but cost a little more. [/QUOTE]
