Universal discharger from Perfect Regulators

There is a cheaper device but rather less sophisticated.

Does anyone have one of these?
It seems from the video that the package includes the connectors and bulbs but from the description on the vendor's website this is not too clear.

Hey Buddy.

Yep, I've got 3 of them :-)
Only used one briefly, but they work very well and light your room nicely. You can parallel a couple of these and this is what I was going to recommend to RichardV, one guy over on RCGroups used a parallel charge board to link 3x of these dischargers together to give a 450 watt discharge. Seem to work well.

I've also built one on this type of design;

I've tried them all.

That's great Ian. The PR one is out of stock so I've ordered 2 of these and EC5/Deans converters. I'm not sure of the maths, so how long would a 150w discharger take to bring a fully charged 6s 5000 down to storage?

They are dam good for their price, you can't even make something like this for less.

I'm still picking up all this ohms law malarky and working the maths out with electrons, but according to what I've punched into online calculators I think it will discharge at 6 amps. 150 watts @ 25 volts comes out at 6 amps.
So a full 6s pack I'd say will be done within an hour. I think, probably have to try to find out :-)

Roughly, it should take about 25 mins to get from full to storage voltage with a 150W discharge, depending on your definition of 'storage voltage'.

Ditto. I used to stand and watch the voltmeter.

I used to tell my Dad I needed more, as these ones were not performing so well :-)

I finished the discharger and I like it.
It takes about 25 minutes to storage charge a full pack.
Cheap and easy to build.
Completely quiet.
Stops on its own and no buzzers. The lights just turn off.
Storage voltage is configurable.
Standalone, doesn't use a PSU or other power source.
Just plug the batteries in and hit the discharge button.

No need to unpack the chargers to discharge. This stays at home

Awesome, well done.
Must do something with mine, it's still in the box :-)

Do you have a url link to them ?
Are the lamps and interface board included ?

[Bob Cole]

Try a 24 volt 70W commercial vehicle bulb and one of these,

I have just ordered the Bangood version.

[Mike Sanders]

I have received mine and tested it. A small buzzer came in the package with a cable with bare ends. I presume it sounds when the target voltage is reached.
Does anyone know where to connect it?

Interesting, got a photo? I'm wondering if you can wire it in parallel with the switching pins to sound when the balance box flicks the swithcing pins?

I didn't get no buzzer, I just shout "DONE!" when mine's finished lol
