Oddly enough that's his nickname down at the Fire Station.

At the airfield? Not so much.

Pulling your leg. Nice work on the charging box.

For several years I've been considering a similar design which would include a 15~20aH gel cell batt (not too heavy), plus inputs on the back (like yours) for high capacity 12v batts + 110vAC & 220vAC -- and for solar panels for trickle charging the onboard gel cell. The ideal design would allow multiple source simultaneous inputting of current, and switchable distribution of the sources.

Gotcha

I like the idea of a small gel cell and solar panels. I need a bigger case

like the box, but what are you gonna do if one blows? i have long enough wire to have the batt out side the box, so i can pitch the batt out the window. If one of ur batts goes its gonna take out ur whold set up.

well 1c, prob not. but u never know when one is gonna go. I prefer to be prepared. i mean i still have my charger and pwer supply on the desk but the batt is in a pelican box. When it goes, i plan to flip the lid and then grab a handle and open window and pitch it, 2 stories down to the ground.

OK mine's almost done. Need a manner to secure the panel up, and to hardwire the chargers with switches.

2 33AH gel-cells may be overkill, and its certainly heavy, but I fly wherever and its a wheeled Pelican-type case.

The chargers are minimal 5S 5A, but two of them are just enough for my 10S setup. I had one for years, and scored the second NIB on Ebay for $30.

Too bad the new one has a green backlight instead of blue..

Here's my charge box; 2 Hyperion Duo's each with its own 430w PS. I built my own switch box to distribute power, the red switches are for when charging at the field off a car battery. The clearish box in the middle under the chargers is a voltage and wattage meter that keeps an eye on my car battery when I use it to charge at the field. I've also added 4 glass containers that the batteries are changed in, might not be 100% fire resistant but would definitely reduce damage if a batter decided to go off.

I need someone with an electrical background to answer a question for me.

I like the setup by OICU812, a lot. I have two 1010C chargers now and I plan on scooping up 2 more. Or buying the new TP chargers that aren't out yet that can charge 2 at once. I know that I am going to need a power supply and a generator if I want to run all these at once.

1st question:

Would I need the 2000W or 1000W Honda to achieve this. I don't have the best "technical" understanding of electricity. I know the EU1000 can handle 1000W and 120V AC @ 8.3A and the EU2000 can handle 2000W and 120V AC @ 16.7A. How does that translate to DC conversion. This is what I don't understand. Is there some math to back up the explanation? In other words, what is the maximum DC amperage that I can convert and draw (for the EU1000 and EU2000) before the honda takes a dump and quits? And how did you figure that number out?

2nd question:

The max output of a 1010C is 10A. Is that also the max amperage that it draws as well? I assume that the LCD screen/fan/internal electronics drawn some amperage as well. So if I was running 4 of them, then I would only need a 40A power supply, right? Probably not. But, I assume it would be less of a load if I ran a power supply that was capable of higher amperage. Also is it better to run 2 40A power supplies or 1 80A?

In closing, I'd like to know the theory behind all the flow of electricity in my scenario and the math so that I can figure this stuff out myself for future projects. Thanks. C.J.

Thanks big fil. That summed up the link between the power supply and the lipo. Now, I just need to figure out the conversion from the generator to the power supply. I think there is a loss in wattage during conversion that involves some math.

But if all things were equal, 1000W / 13V = 76.9A DC? So, in OICU812's case, that 75A power supply in right in line with the math.

A thousand watt generator would be capable to run 4 tp charges at max output but it would be a load. i would go with a 1500 watt rating gen. Just make sure that the gen is rated for 1000 watts continuous. My honda 2000 watt is actually over rated it only provides 1600 continues. You want some room. I always go 80 percent just to be safe so a 1000 watt gen would be the minuim just make sure it is rated for that.watts= volts x amps I would get a the 90 amp power supply that iota provides the 70 amp will do but it is just enough when chargers are charging at max. Some math for you 12 volt power supply that supplies 70 amps is 840 watts power supply. 1 charger charging a 10S pack 42 volts x 5 amps = 210 x four charges is exactly 840 watts. Give alittle for efficenty. Like i said it litterly takes all of what the power supply can handle. hope this helps

Sounds like the EU2000 is the way to go. That's the one I wanted anyways, but at least I know why now.

This (see YT video below) might throw a wrench in the gears though. 400W per side, means you could only run two chargers on that bad boy. Ouch!! But, 20A x 2 ports isn't anything to shake a stick at. TP 820CD, here I come!! Make it a double please.

Honda generators
They only output 8 Amps@12V = 96 Watts.
You would have to use an external converter(power supply) to convert
120AC to 12DC. Here is where im not too sure, but if its EU2000iA, then it has 1600 watts continuos and 2000watts peak, but for our continuos charging purposes you can count on 1500 watts. In the case of the EOS dual chargers it has to have available at least 720 Watts.
So in theory it will work.

Power supply
MTB:

Are you using 12v power supplies or 24 Volt????
Im using 24V@15amp units which are 360 watts.

The power supplies are running at 12v and 430 watts. I can charge my 10s packs at about 7amps. each charger running a 5s on each side which are synced together... makes getting ready for a day of flying go much faster.

MTB, how did you end up hanging your DUOs? With the DUOs I wish they had a larger flat contact spot on the bottoms.

I've found going with 24V i'm able to get 8.4A out of the duos with 5s packs. But in all honesty with two running at 7A each it's still plenty fast.
