See, I would normally be like, "how do you have an old Inspire 1 case?",
My business partner purchased aftermarket cases for both his Inspires, so he actually had 2 OEM cases laying around doing nothing.
but considering the fact *I* actually have an extra Inspire 1 case (part of the zipper is jack at the back on the bottom right corner), I can see how these things happen...
Well that's just funny, because Derek (my business partner) brought one of his cases and the zipper was jacked in exactly the same manner! - which is odd, because the zipper on my OEM case works perfectly. So he brought his OTHER OEM case over a couple nights later, and that one seems okay.
I will have to hit you up when I am ready to build an "on-the-go" charger setup here this spring. I figure just the OEM car charger will be fine to start,
It's not. A cigarette lighter is a horrible source of power. Back in the day, when cigarette lighters were actually lighting cigarettes, they were fairly robust - 10 amps I believe was standard. Now they've become "power supplies," and don't seem to be as robust. Dollars to doughnuts there's a 5 amp fuse behind it. The power supply I built is near perfect. Once I get it in the case it will be sweet.
Not sure how electrically savvy you are, but usually batteries require a battery charger, which is different circuitry from a pedestrian power supply. However, the DJI smart batteries are sort of "self managing." So one doesn't need actual battery charger circuitry.
Also...worth noting, the step-up power supplies are more efficient than power supplies that can also be stepped down. So I purchased step-up power supplies.
Interesting side note; The Mavic battery is a 11.4, 3S battery (Normally 3s is 11.1v, but not for the Mavic battery according to spec). But it takes a charging voltage of 13.05v. So, in theory, I BELIEVE one can charge the Mavic batteries directly off a car battery. I believe my step-up converters can be lowered to input voltage. When the car is running, voltage is 14v. When it's not, the battery nominally starts around 12.6v. So...I may be able to step up the voltage to 13.05v if the car is NOT running. Since my car battery is a 70Ah AGM battery, I should be able to charge at least five 4Ah Mavic batteries before making an appreciable dent in my car battery's voltage. It's all theory at this point, as I have never needed more than 3 Mavic batteries at any Mavic shoot. Because if its diminutive size and "good enough" camera, I use the Mavic for any real estate gigs that pop up. This has always consisted of only one battery. But I digress....
but if I need to charge multiple batteries I can most certainly see the advantage to a dynamic setup like you have.
Absolutely. And remember, the best part is that you can quick charge your batteries. I limit my quick charges to 6 Amps, which is only 160 watts, which *under* the charge rating of the DJI 180 watt "quick charger." I have tons of head room to boost the charge to 7 or 8 amps if I wish. But what I'm discovering is that charging 3 Inspire 1 batteries at 6 Amps heats up the alligator clips pretty good. I THOUGHT the alligator clips are rated @ 50 Amps, but apparently I screwed up and they're only rated for 20 amps. ARGH! So I have to order some new, more robust clips.
For me it is all about the options... Gotta have the options... No need for limited designs...
Oh yeah...because I can set voltage and amperage and have set them up to receive banana plugs, the sky is the limit. I can charge or power anything over 14 volts. I may make a laptop charger cable next.
