CoCo,
I can see them just fine.

All images came out ok here before and after and quoted. But loading to HF will ensure longevity and most likely get consistent viewing for everyone

Ok, sorry then, I checked better and I can see that I get a DNS error for u.cubeupload.com.

I am currently in South Korea, that's probably something related to that.

Default My Ultimate Charger/Discharger Case

After almost 4 years planning and 18 months' work, we finally finished the built of a new version of our charge case. It was accomplished as collaboration between myself and my friend Pedro Simoes. We're really happy with the outcome.

This project expanded further into complete charger and discharger case solution that includes a tablet PC receiving and streaming information wirelessly to my handheld device like a tablet or my phone; data is displayed in real time.

Having a Windows 10 computer connected to the chargers all the time, is super convenient and allows me to use the same setup to configure all the gadgets like ESCs, FBLs, FCs, BECs installed in my models, download the telemetry and setup files from my Spektrum radio and even have access to the Internet in case that I need to research something while at the flying field.

This unit incorporates a custom designed protection circuit which is designed to safe guard the chargers and the PSU against damage when any of the following events happens:

(a) High amp spike
(b) High inrush current
(c) Power outage causing unexpected PSU shut down
(d) Under voltage protection
(e) Over voltage protection
(f) Over temp shut down gauged by 7 probes

Basically you turn the power switch on and the protection circuit takes charge powering the fans; after 5 seconds the PSU is powered and then a few seconds later it powers both chargers.

The beauty part is that if the power goes off or any of the above mentioned incidents happens, the relays resets so when the power comes back on the PSU and charger don't automatically turn on which means I can disconnect the batteries if any are on, turn off the charger and restart everything afresh so I can make sure everything is ok first. The fans, however, are kept turned on so you still maintain cooling.

The discharger is capable of discharging current up to 40A although I usually discharge no more than 20A. The process is controlled by iCharger's internal function which is connected to a 1000W 1ohm resistor, conveniently sited under the hood of the charge case.

Efficient heat dissipation is taken care by external very powerful cooling fans controlled based on temperature, the cooling fans in my case can be programmed to turn on when internal temperatures rise, so they are not running at all times.

This is what is inside:

1 x Charge Case: metal and wood
1 x Protection Circuit
1 x iCharger 4010Duo
1 x iCharger 208B (external)
1 x Mean Well SE-600-24 600W main supply running at 27V
1 x 12V PSU dedicated for the protection and cooling systems
1 x USB 5v 2.1A socket.
4 x External power outlets
8 x 12v Cooler Fan San Ace 40
2 x 12V PC fans
1 x 24V outlet for an external charger
1 x 1000w 1ohm resistor for the discharger
1 x Touch screen tablet PC Samsung with external USB ports

WOW! And I thought I had a cluster f#ck of a wiring mess in my case!

Beautiful job by the way!

Here's two I built, the ISDT is mine and the other is for a friend. Both 25V 50amps, one has an aux connection for a car.

Nice job! That's some serious horsepower there with two RSP-2000-48 power supplies!

Thanks, yeah I kind of went a bit crazy! I power them with a Honda EM5000SX genset bolted in my truck at 240V.

80 amps total charging current! I wanted to charge four 5000mah batteries at 4C!

I installed a raspberry pi 3 and connected it to my 406 duo and can now manage my charger from my phone or tablet. It's pretty cool.

240V is nice, you'll actually be able to get 2000W out of those supplies rather than 1600W with 120V AC.

I do nearly all my charging at the field and my limiting factor is my Honda EU2000i.

You could always get another 2000i and connect them. I don't think you can get 240v, but you can get alot more amps for one of those power supplies. The PS can pull up to 16 amps at 120v

I have an EU2000 as well. Nice and light when I need portable power.

Most people don't realize that those PS's are rated at 220-240v!

I field charge as well. Been using the EU2000/24v server supply and PL8 for years now. Great combination, but now that I've been flying my 700's more I needed a quicker charging solution.

Even the EU3000(inverter) doesn't offer 240V. Need to go with the bigger gensets for the higher voltage. I "needed" the EM5000 genset for work, so it worked out great for powering my hobby needs as well.

Unfortunately, you don't get 240v when running in parallel. Having one eu2000i hasn't been a bottle neck for me at this point in time. I'm using 6s 4400mAh packs and can charge two of them simultaneously (not in parallel) at 3C which and I'm pulling just under 800W from the generator which is half its continuous power rating so I have some room to spare. Having multiple sets of packs per heli I don't have much waiting time.

I thought about picking up an eu1000i for those lighter days at the field since it's half the weight.

Now, if I had a trailer, an eu3000i one wheels would be very nice.
