Default Novak Smart Tray revisited

Now that I have had some time with my Novak Smart Tray, I seek some input from the "peanut gallery".

First...While running everyone's equipment on a generator at the track, the Novak indicates "LP" (Low power) whenever there is not enought juice available. At these times, I tend to get false peaks from my chargers. I consider the "LP" notification to be a time that I need to watch my chargers.

Second...The electrical connect plug from the included power supply is very fussy about being plugged into the tray properly. Anybody else experiencing this?

Third...Almost invariably, the right two cells (as placed on the tray) go out first. They are followed by the left cell and then the other three. Anyone else experiencing this sequence?

Fourth...When discharging to .9V per cell, I need to cycle through them 2-3 times to have the cells discharge to .9V each. The first discharge cycle never completes the job. And each subsequent cycle still takes several minutes for the last lamp to go out. Doubt that this is much to do with "cell rebound" because I immediately press the tray's start button after all lights go out.

FYI...I am discharging most of the way down with lights before traying the battery packs.

Any comments?

this is why I still love the indi/integy trays.......0v cutoff, just keep your eyes on the light bulbs, it's worth to me and the integy trays are muuuuuuuch cheaper than any other.....

I noticed the plug seems to not fit in the jack right too. As far as the other items I'll have to check out.

I don't like that it only accepts packs built one particular way. Something I didn't realize to be a problem at first but having to flip the pack over and have the tabs down can cause some problems.

Salvadori Racing,

I also have Indi/Integy trays; however, I also know when something is technologically better...And that is the Smart Tray.

I don't have to keep my eyes on the light bulbs every time I tray discharge...Which is worth the initial cost alone.

Yes, the tabs being in the wrong direction was an issue for me too. Thanks.

i have some questions:

Could someone compare the

Smart Tray vs. the Rayspeed.

How often do you use your Smart Tray on something other than 0.9V per cell?

Also, you discharge with the bulbs at 20-30A prior to hopping on the tray equalizers, right? This is just to save time?

These dischargers have previously been compared before on other strings. Use the search function to find what you want.

Otherwise, I only use .9V rate. Yes, using lights does save time.

Still looking for replies from others that actually are using the Smart Tray.

Thanks.

I haven't had any problems with my Novak Tray. I have noticed that I have more capacity and higher voltages than when I previously used a Pro-Match Tray. The Novak Tray works faster than the Pro-Match Tray(it would take most of the day with the Pro-Match). I wouldn't use anything but a Novak Tray now. I have only used the 0.9 volt setting so far.

the only help I can give you Billis when I use my Smart tray I first discharge my batteries on my 30 amp integy discharger with cut off, then my batteries equalize within about 3 minutes and the always cut out in a different order. Also if I try to retray the light turn off right away again. Hope this helps

So far from what I can remember all of my cells have discharged in different orders. I'm going to keep an eye on them from now on as I find this topic interesting. I haven't had any problems with the plug coming loose either...yet....

The lights on my tray have been going off randomly. No pattern there.

I did find that I had to flip my saddle packs to get it to match up. I solved that by resoldering the connectors.

I did have it hooked up yesterday to a power generator and noticed that LP come on at times. This is definitely annoying, however, I don't mind since this tray does allow the use of AC or DC.

I don't regret purchasing this. It is way better than the Smart Tray (which does take forever to equalize).

That is what I was wondering about. Seems as though there is something wrong with mine.

After I do retray a pack 2-3 times everything is as I would expect it to be. Otherwise, I do get far better mahrs and voltages than what I got with my previous discharge tray.

I had the same problem. After I cleaned the contacts with motor spary the problem went away. I cleaned the contacts on the pack as well as the contacts on the tray.

It's a possibility. Thanks. I will give that a shot (of spray).
