Is it too late for you to cancel your order?

Normally I'd do any mods necessary to make things work, in this case I decided the RDC45 was just too much, and I decided to spend the $ I saved on a FlyCam- was hoping that and the PS would show up yesterday, looks like it'll be Monday.

I'll have a clean setup with the charger/PS..... eventually lol

unfortunately yes... it's left the shop yesterday =) The bloke answered my email at 8-9pm on a Friday night (i had sent the email some time around 6-7pm that same night), and he posted it Saturday! Very quick, great service, and at a cheap price! Everyone else i had seen selling them were up around the AUD$350-400 mark for the exact same thing... Spose i cant complain - it's more than capable, but thanks for the heads up George =)

Features :
Switchable 110/220 volt 450 watt switching 12 volt DC power supply with a ON/Off switch. It has one internal light indicating power on and is capable of putting out 30 amps max. It has thermal protection
is this one any good

Any link?

http://www.nitrorcthunder.com/Power%20supply.htm ya whoops, forgot.

Don't feel regret. Yeah, it's probably more than you'll need but at least you know it will never be overworked!

I really wish these chargers could utilize anything from 12v all the way up to something like 36v DC. That way, you could use them in a car, but then use a ~36vDC supply in the house for about 1/3 the current. High current is what makes these supplies expensive.

http://www.nitrorcthunder.com/Power%20supply.htm does any one know if these power supplys are any good?

It looks like a pre-modded computer supply. Big tip-off is the empty grommet where all the wires would normally be routed:

For another thing, most computer supplies put out exactly 12v. Once you load it down with high current, the output voltage drops, possibly below what the charger wants to see. If you mod your own, you can sometimes increase the output voltage to at least 13v. Not only does this give you a little extra cushion for voltage drop, the higher voltage also means the charger will draw less current (which reduces the voltage drop).

Are you saying that it might not work with a duo using high current?

Well, I cen't really say without testing it or even seeing the guts to see. Just don't be surprised if the voltage falls too low under heavy load.

Brian, what power supply do you recomend i should get for my duo thats no more than $150? I might be charging two a123 6s m1 packs in the future at some point. I just want to be able to charge a123s as fast as there able to be charged. Thanks for the relpies also.

I'm going to be getting one of these when I get a Hyperion DUO

here is a link to some PSs that look a little ghetto from the outside but perform well and they are half the price of a Bulldog

have you tried any of those with the duo?

jlustig, I should have my Hobby Lobby 30 amp PS tomorrow hopefully and will give some more details- hang tight ;)

Ok thanks redshift .

What charger are you gonna use with that ps and what type of batteries are you charging.

lol have you read any of your own thread?

I have a brand new Duo, will be charging 2S FP 4900 and 2S MA 6000 at 8 amps per port. which is a bit over 1.5C for the FP's and slightly under 1.5C for the MA's. Charge time is around 35-40 min.

I havent gone through the old posts for a little while lol. Any way let me know how that 30 amp power supply works cause i will probably buy that one or the 40 amp one.Thanks Redshift.

Two big thumbs up!

But wow this 30 amp is actually bigger than the Rivergate 45 amp I returned. It is 13.8V output, not just 12 like I feared, I got 13.7 on my meter. There is a 3" fan in the back, and a fuse, and the cord is nice and long, about 5 feet. The output lugs are beefy and it has a large power switch.

Mike needs to carry these so I don't have to feel bad about giving something he doesn't carry a good review...

I'm impressed- and for the money I'm really impressed!

Did you by any chance open it up? I'm curious if there's a little fine-tuning pot in there to tweak the voltage to ~14.5v.

I'll get some pics and post up a bit later Brian....

Negative on that Brian- there are tamper-proof screws in the case. 13.8 is gonna have to be good enough ;)

The fan runs all the time, but it's quiet, and there are 2 way output lugs- they'll take banana plugs in the front and there are screw-pinch terminals with large gauge holes. Looks very well made, i really do think Mike should consider stocking these!

man thats cool. im for sure gonna get the 40a one now. thanks.

Yeah I'm glad I did the swap- you can't go wrong with the 40 amp for $100- could probably buy a pack with the $ saved.....

i dont want to be off topic but i have one question,,,,ive buy this charger and its a very good charger:yes: ..so a saw when my lipo are charging that im able to see the resistence of the pack.. what tell me if my lipo are in good shape,,,if the number is hight or low???ex.my two 4800mah 11,1 zippy-r are 40mΏ


they are in good shape or not??

thanks

The lower the number the more "ideal" a battery it is. "m" is milli, so they are 0.04 ohms. Not bad. Battery resistance is not linear though, meaning the resistance will be a bit lower at the high currents. If it was a flat 0.04ohms for any current, the voltage of a 11.1v pack would drop to 7.1v @ 100A. The best way to gauge a battery's performance is to graph it real-time under the heavy load. But, at least this gives you a relative idea compared to other packs...

thanks BrianG:yes:i was scrad that my pack was a crap....
