Nice

1400 watt per port (2000 watt limit)

130 watt discharge per port (200 watt limit)

Should cost a pretty penny


Cheers

Wow. A mufti-port charger that isn't wimpy. Could be interesting.

Its definitely beastly. We'll see how much it is, though. I'm betting at least $500... from Hobby King. O.o

That should be really interesting.

I like that everything plugs into the front.

I want to see more information! I was looking at possibly getting another charger and this one looks pretty amazing.

Look at the input voltage, 50 V and that means 4 * 12V battery in series to get the max power output. So lets see what it can do on 24V

Bart,

50v isn't bad... that's just 4 $10 computer power supplies in series.

My bet is that it has an ~50A input current limit similar to the 306B and 3010B. This would limit maximum charge power to ~1000 watts, perhaps slightly more.

My second prediction for the day is that this one won't be a hot seller in the US as it will have limited power on US standard 110V/15A service, and will require 220V or a massive bank of deep cycles to extract full performance. Plus, given that it has a face only a mother could love, it'll have to come in well under $400 to attract many buyers.

I personally would get two PL6's (or PL8, 306B, 3010B...) before thinking about this charger as they would be more versatile and would not require a special power supply or 220V circuit to operate at full tilt.

IMO, Junsi would be much better served increasing the output current capability of the 306B and 3010B. Introduce a 406B and customers will come running with open wallets....

Good points, Mark. We really don't even know if it will be released in the US yet or not. And possibly for that very 220v reason.

Last year at a fun fly, Dave from ProgressiveRC mentioned that it might be a good idea to get your charging area set up for 220V for the next generation of chargers. I don't know if he was thinking of this one specifically.

I e-mailed EP Buddy yesterday after I saw this thread.

Dale's reply was it has been in testing for about a year and should be available this summer.

About the 50V, it doesn't say anything like "it will require" 50V.
It only says it can take up to 50V input.

And I'm not so sure 220V is on its way in with respect to powering chargers.
If I can get 36V or 48V from multiply PS, would they require 220Vinput to get that kind of output? Or are we talking about tripping 20AMP breakers?
At twice the input voltage, isn't that half the power?

220V AC is not that big of a deal even in the US. All houses have it coming intio them. Most electric water heaters, stoves,electric central heating and air conditioning, clothes dryers,some wimdow AC units. The bigger issue would be at the field as most do not have 220 AC at the pits and most unbder 5000 or so generates do not have 220. 4 Deep cycle Pbs ,right,most complain about the weight of one.

Very true, but I would be completely shocked if it could accept more than 60 amps on the input. Even this is pushing it. At 60 amps, it would require nearly 40 volts DC input. 40 volts is not easy to come by.

A single 110V/20A circuit won't cut it.

Quicky math on the absolute maximum charge power one could squeeze out of a 110V/20A circuit:

Generously assuming 90% charger efficiency, 80% PS efficiency, unity power factor, and zero line losses, max charge power would be ~1600 watts.

Either a hokey dual 110V circuits running two separate power supplies that are then connected in series or a 220V circuit would be required. Not a single one of my friends has 220V available in their charger/hobby room. For many, 220V service in a convenient location would require a visit from an electrician. Electrician's aren't cheap.

If I needed two 40A, 1000 watt chargers, my $ would go on two PL6's. And this coming from a diehard iCharger fan who owns 4 iChargers and uses them exclusively.
