Here's a cut&paste info from Novak website about the discharger:::

The Smart Tray Discharger is the ultimate battery maintenance equalizing system. The key to its simple yet accurate performance is its Individual Cell Monitoring Circuitry (ICM), which provides the highest degree of care and accuracy for all batteries, including Novak's new Orange Power GP3300VE cells.

The Smart Tray features a digital microprocessor-controlled battery discharge circuit that utilizes ICM Circuitry. This Novak-exclusive Individual Cell Monitoring circuitry accurately discharges and monitors each individual cellís voltage, and has an LED at each cell that indicates its discharge status. A user-programmable cut-off voltage is constantly displayed on a large easy-to-read 2-digit LED. Once the cut-off voltage of the individual cell is reached, the Smart Tray automatically stops discharging that cell, eliminating the need to monitor the pack. One by one each cell is discharged, indicated by its LED going out. When all the LEDs are out, the pack is discharged and equalized.

With each cell receiving individual care and attention, you'll never have to worry about damaging your batteries because you've left them in the discharge tray too long. Because the Smart Tray stops discharging once the cut-off voltage is reached, your cells can stay in the tray without getting damaged. Simply set it, and forget it. A large heatsink provides ample cooling for discharge components, while a lexan cover protects the electronics.

The Smart Tray has a "Dead Short" mode which does the same thing as the deep discharge trays... to enter the dead short mode remove the power supply from the tray, press the button and then while holding the button down, reapply power to the unit. Next, release the button and the display should read "ds"... signifiying that you are now in dead short mode..

Now when you place your pack in the tray and press the start button, it will continually discharge each cell... once the cells have gone below 0.1V the LED's will start to flash letting you know that the cells are for all intents and purposes discharged to zero... you can leave your cells in the tray as long as you would like.

DISCLAIMER: Novak Electronics does not recommend dead shorting or "deep discharging" your cells.

Hey Evicerator-why no dead shorting? I know this is a strong belief of Novak and its Orange Power cells-but I would like to know why, please.Thanks,
Ray

Erik-- Thanks for the "video" of sorts... will you be getting the lemon and wire brush out for the next version?



Ray,

Because every time we've dead shorted batteries we see little(experimental error?) or no improvement in IR and average voltages and significant loss in run time.

To expound upon the experimental error that I touched upon above: I've seen just as many cells have LOWER voltage than have had higher voltage after being dead shorted...
Which leads me to believe that there is no significant voltage gained by dead shorting...

This being the case, the total power that the cells provide will be less due to the significant loss in run time that occurs every time you dead-short your cells. Also, this significant loss in run time will mean that the discharge voltage curve will not be as consistant over five minutes.


That, in a nut-shell, is our view

We shipped out more packs last week I think?

Which means they should be getting to hobby shops soon...?

When is the new top-o-the line speedo coming out?

Sank-u very, very much!!! I have some fresh sticks with only two runs on them and have NOT been Dead Shorted. I will cycle them in a month or two and see how they are compared to my last packs that were DS since NOvember. It should be very interesting.

Thanks this does help me out alot. WHY does it says on the Smart tray-- equalizing DISCHARGER . Discharger here i come

i already have a rayspeed discharge tray. does the novak tray offer any advantage or disadvantage over the rayspeed?

i heard that the rayspeed dischages at 5 amps, while the novak at 2.5 amps... wouldn't 5 amps be better than 2.5? just thought.
