Some of you guys are really missing the benefit of deadshorting. When you DS, you are starting your batteries from zero, and as you know the first third of the discharge is the strongest, then the next, etc. By bringing the cells down farther you are increasing the time of the initial punch since you are charging more up. You won't lose much run time, and especially in stock where you don't have to worry about dumping. You aree charging the cells up from a dead/zero state. DS and zero are the same, ds is a way to keep them there at zero since as soon as you pull them out of the tray they will naturally build up some voltage. If you keep them in the tray, you don't have to solder a wire.

Sorry to rob this thread a bit-but a guy asked me how to DS a pack with solder and a few other questions. It became apparent pics were required so I dont get accused of burning down his house when a batery goes pop.

Here is a battery that was discharged fully on a Indi Octane 2 or a Novak Smart tray in DS mode. After the pack was at zero-I attached the DS wire while still in the tray and then removed the pack from the tray.

Any other questions-better ask them before attempting to DS your first time.

btw-the advantage of solder is if there is some residual charge left in them-it will melt the solder and not heat up the DS bar or worse-the whole pack. Thanks to Rob for the 411 on that.

And I guess alll this DS bar BS all goes away when you use the Novak Flatliner So there you go-heres a great reason to use the flatliner-safety for your packs and your body.

Also, if you don't beleive in the Deadshorting technique to New Packs, I'll help liven up old packs or abused practice packs too.

Thanks Ray, You make a very good point.

so do you guys know if this thing ds each cell or the pack?

Sorry to go a little off thread but how do you dead short with a Smart Tray. I have one and have used it for more than a year do discharge but not yet to DS. How do you do it. I see it has a DS mode but I can't figure how to get it to work. I can't seem to find my manual or even an online manual from www.teamnovak.com. Also how long in the tray does it take for a pack to benifit that has been charged like 100 times and never DS. Thanks

I am running 8min 23T stock and start deadshorting my cells a year ago. I have stop using DS anymore since I found that it is not a really good idea.
Yes, rayhuang is right, the pack will stabalize after losing the first 20-30s runtime and voltage will increase abit and gives more punch. I have taking over 300 times experiment to find out the difference. What I can conclude is by DS your pack, you can get more punch and top speed for the first few minutes (around 3-4min) only. After the first 4 minutes, all the voltage and punch feeling will gone resulting a pack worse than non-DS pack.
The result is proved by looking at the discharge curve of the DS/non-DS pack.
Another interesting thing is that by DS your pack, you can easily charge a GP3300 to 4000mah but the actual runtime is less than a non-DS GP3300 charged to 3300mah!

For your interest, a discharge tray with individual cell cutoff, individual cell voltage display is coming......

Dustin,
Hold the button down, while pluging the power in... it'll say "ds" where the voltage should be.

Seems abit late for this product as IB cells are not recommended to be DS.

Ok now I see how to DS. I should discharge to .1 per cell and then DS? Can someone confirm. Thanks

You can or just go straight to DS rather than 0.1 volt.

No pack is recommended to be deadshorted, but it definately helps the power output of the pack. I've run deadshorted 3300's with a 6 turn motor for 5 minutes without dumping, and now with the 3800 cells we have avalible, dumping shouldnt be much of a concern for anyone.

Randy. What is your experience with DS a 3800 pack? Since it isn't GP, does it afffect them differently? I would assume the GP3700s would be similar to GP3300s, but 3800s?

Randy Caster

I havent tried a DS 3800 yet, but I'll give you guys the results when I do.

centax error!

I found that if I ran a DS pack for the second or third time I felt a decrease in performance especially punch.... do you guys only ran DS pack once and keep it DS until the next use(week)? btw, I'm using GP3300.
