[QUOTE="Virtual1, post: 21327, member: 4084"] >> the Charging Station charges up to three Spark batteries in 2.5 hours when fully charged. 2.5 hours to charge three batteries? pass. But when I go to the park I bring all my batteries (6) and the full sled charger, along with an 18AH 12v SLA battery and a 200w AC inverter. I've found I can't charge them fast enough to "fly nonstop" but it's close enough for me to not waste the daylight. If I can just sit and take a break for 5 minutes between flights (including those first few when I [I]have[/I] batteries charged and ready to go!) I can fly basically nonstop all afternoon. (gives me a little time to top off the phone/pad/controller too) Being an electrical engineer of sorts though it irks me a bit to take a 12v pack, invert it up to 120vac, and then step it [I]back down[/I] to 12v or so to run the sled. DJI needs to make something that runs directly off 12v and can charge [I]at least[/I] three batteries as fast as the sled for those of us that want or need high duty cycle. It needs to at least come close to 100% uptime by charge speed and number of batteries on charge at a time. 12v batteries aren't that hard to come by, and if nothing else you can just use the cig lighter in your car. There are several aftermarket models of charger that are intended on running off the cig lighter jack, but they all only support 1, 2, or 3 batteries so I may just get a couple of those. I'm also working on getting my cables in order so I can put a 10AH power bank in my pocket and keep my kindle charged while flying. (I don't think I can do that with the remote... it seems to [I]shut off[/I] when charging?! I can't even name another usb-charged accessory I have that refuses to run while charging or running off USB power) [/QUOTE]
