Actually, if I was going to charge at rates higher than one 120V/20A circuit could provide I'd do like Tyler did and run the circuit to an exterior wall and charge outside. I do have two 20A circuits in my garage I could use or run to an exterior wall. I don't want to take any chances charging lipos at max power indoors.

I take every opportunity available to be a poster boy for safety, especially after I suffered through the hard knocks lesson myself.

Guys!!

Don't charge hard and fast in our house or your garage!![size=large]

I had a house fire from a battery just over a year ago. I don't want to repeat that. Fortunately I was able to cover all the repairs, expenses, and labor myself without an insurance claim or displacing my family (happened on Christmas Eve).

I charge outside, PERIOD!!

Having said that, I do enjoy high power charging and the safe peace of mind with my set up.

Enjoy things that money can buy IF you don't lose the things money can't buy.

BradNewman,

consider using a single 3000 watt power supply on 240v. Under $50 if you find a good deal. Simple, easy, and all the protection you need.

There is no floating the grounds or other debatable concerns. No worries about one power supply dying and causing havoc on the charger when it drops out. No shock hazards.

Good safety points, Tyler!

I really don't plan on doing any highpower charging at home because I'm not in a hurry then. I have 2 circuits only to make sure nothing is stressed at all. I will now be doing the large majority of my charging at the field.

One PSU dropping out is a concern with the 4010, but the DPL8 will shut itself down if that happens.

I bought 4 of the DPS 1200 FB's for $80 shipped, if you float the grounds properly they are safe, and unless you are charging over 6S you'll never get any advantage out of 48v...infact it could cost you, as power supplies operate more efficiently when loaded up.

Many choices, and no single one will be right for everybody.

Good luck with what you decide...I'm just glad my search is over...now I can get back to deciding which heli is next!

Some corrections and clarifications.

The Dual Powerlab has two separate screens and controls. Both channels can be set and monitored separately. Or you can link the two channels together and control both channels from one set of controls.

The Dual Powerlab has two separate channels cable of up to 40 amps and 8s, or 2688 watts total (1344 per channel). The 4010 is cable of up to 2000 watts total. One channel can reach 1400 watts but the other channel will be limited to 600 watts.

The internal discharge power of the Dual Powerlab is 95 watts per channel, or 190 watts total. The discharge capabilities of the charger has been extensively tested and using to it fullest will not put the charger at risk.

The 4010 has 200 watts of discharge capability. Or a max of 130 watts on one channel, but the other channel will be limited. However, many knowledgeable experts have recommended against using the discharge feature due to the risk to the charger.

Who makes 3kW power supplies? I'm using a single 48V 1500W which is the largest 48V supply Cosel makes as far as I know. Mean Well does have a 2kW 48 supply.

I went with the single supply issue to avoid the size, weight, and risk of multiple 12V supplies. They are also specifically designed to run in parallel/series. They are also available as surplus so you can find them at reasonable price too. Not a cheap as server supplies, but significantly less than purchasing new.

Unfortunately, my field does not have AC and using two EU2000i generators doesn't seem very practical for me.
Well I guess I am silly lol because at our one field where we have size limits, I will only bring one generator, but I am looking at our other flying site (where anything goes essentially) and at larger events like IRCHA, I plan on bringing two and running one to each power supply

Okay, I have seen that one before. From the input requirements it doesn't look like it will even run on 120V AC. Is that correct? Would be nice for a permanent installation, but if it can't run off of 120V AC it doesn't seem very portable for use here in the US.

I was thinking more or less of everyday use. Yes, IRCHA is a special event. It wouldn't want to have to haul two generators ever time I went to the field.

If you have two EU2000is why not just run them in parallel?

What's the voltage output range on the ESP120? The DPL8 has a max input voltage of just over 48V. Looking at the label for the ESP120 I see it's 51.4V so it would need to be dropped to 48V for use with the DPL8.

Output is as specked, 51.4 volts.

The iCharger 3010b could handle more voltage than a PL8, which allowed it to run on three in series server supplies at 37.5v.

The iCharger 4010duo can handle more than the DPL8, which allows the power supply and a fully charged golf cart to be used.

The voltage can be dropped slightly if you operate internally. Not needed though. The iCharger does trip a warning, but then goes to the home screen.

With a Honda, carrying more than 1,600 watts in power supplies is a waste because the generator can feed any more. I use smaller units for my mobile system.

220v only.

And it is big and heavy.

One large fan is quiter than three small high speed fans, or four.

Agreed. My goal is a single solution, so I'm using a single 1500W 48V power supply.

The biggest problem I see with the ESP120 is the size, other than that it looks great.
Do I understand this correctly...If I run PS's in series and one goes out it will mess up the 4010, but not the DPL8?

Remember to keep everything balanced!

Not always will there be damage.

The size of the power supply is not a problem for stationary charging stations.

However, I have seen guys strap four smaller power supplies together and overall have more weight, larger footprint, and additional A/C wires.

Don't forget the noise of 4 to 8 smaller high speed fans screaming away. This larger unit has bigger and slower fans. My experience has been that it is much quieter.

I read that on another site, but someone here said it wouldn't.
I would do some more research from the guys that really know.
They are who I learned what little I know from.

There are also some supplies that have variable speed fans.
