It does. It also looks like a piece of medical equipment. It's unfortunate they didn't pick another color for the case. But, I'm sure someone will make a wrap so people can cover it in vinyl blue flames easily enough.
So far, though, I'm super impressed. It's the only dual charger I've used that isn't just two chargers in one case. It's got a shared brain, so to speak, so all profiles you create are accessible via either side. It's also capable of slinging more power than just about anything else out there.
The 40A discharge is a bit misleading. It needs to be powered off a lead acid battery for this to work. It will use that as the dummy load by putting the discharged juice back into the lead acid rather than dissipating the energy as heat. It also has the ability to discharge channel A into a dummy load on channel B, like a bunch of auto lights, for example.
The Junsi guys are active on the forums and have been taking feedback for bugs and feature updates. We could probably convince them to duplicate (and expand upon?) the discharge functionality of the GFX.

Also, the end voltage is adjustable. It can write logs to a microSD card that can be viewed with logviewer. The screen can tilt fully vertical. And it's actually not that big. Here's a picture with some perspective on its size. It is rather heavy though. Also, here's a video someone made showing what the display looks like during charging.

Hi Guys,
I also recommend the Revolectrix chargers, 10XP, PowerLab 6 / 8. The PowerLab series is completely programmable and can probably charge all your packs at 2C simultaneously. (Up to 40A charge rate on the PL6 and parallel charging)
You can also hook it up via USB to your laptop to graph various parameters.

Well you guys just made talking about my LRP PULSAR TOUCH in to a lame statement.

GT power. multi mode memory, full graph of charging cycle, 7amp charge rate. $50. Perfect unless you need a higher amp charge rate. You can then spend the other $300 on high discharge 100c batteries! I know plenty of people that spend hundreds on charger then run cheap 50c lipos

Powerlab 8 all the way. The computer linked software is very easy to use. Cutoff voltage can be set to virtually whatever you want. Sky's the limit! LOL
I keep the old trusty GFX handy for bench racing batteries.

Power lab people,
The 6 and 8 are similar except for out put charge and discharge?
Using the daisy chain idea means charging two batteries at once through one out put wire?
Can you change your peak volt cut off?
Charging above 3A you need to have a discharge wire coming from the battery?
You have to use a lead battery for full 40A discharge of what size?

The 8 has slightly higher output and a few more unbalanced charge options. For car racers there really isn't much difference.

THe PL8 will parallel charge with the appropriate board. It's effectively connecting two to four identical batteries of similar discharge to a board and charging them at the same time.
That's where the 40A charge come in to play. To parallel charge 3 batteries at 5A actual amps, your charger will have to output at 15A. The load is balanced across the 3 batteries. Cell count adds into the wattage too. 10A at 2s is half the watts as 10A at 4s.

Can you change your peak volt cut off?
Yes, very easily with the computer link. You can set it low like 4.1v or way too high 4.28+
Charging above 3A you need to have a discharge wire coming from the battery?
To charge at high amps you have to have a balance connector connected. The charger needs to accurately see the voltage of all the cells. There are good instructions on making your own connections with bullets style batteries. I can show you pictures of how I made mine.
You have to use a lead battery for full 40A discharge of what size?
It would be any large deep cycle boat battery or something you have in your car or truck. I have a T35 that I use for cycling packs.

While I consider the PL8 the best, it did take some research to get the cables made up how I needed them. The above thread or PMing me will help someone avoid some of the growing pains.
