Default Dead Shorting?

I recently started dead shorting my packs when I started racing stock, because i figured I wouldn't need the run time as much in stock, and i also like the extra punch that it gives. But what do you guys think about dead shorting packs, and it's side effects?

If you mess up once, you ruin a pack....I don't do it, I race stock and have shorted my batteries before and havn't noticed enough of an increase in preformance to require me to continue to do it. I havn't shorted for years. Also, its not good to do on NiMH cells, only NiCd.

I've done it a lot and stopped because it wasn't a noticeable gain. I did notice that it became an extra step and a pain. Don't dead short for more than 24 hours, do it right and watch for false peaks.

Try a search.......this topic has been fully discussed just recently ...........by the way, dead shorting works just fine on all of the versions of NIMH GP3300's.........just make sure that you have the pack at 0 before shorting them and you won't have any problems.........

Some of my best charges come after the pack was deadshorted for a couple weeks..........the thing about dead shorting (like maintenence zapping packs)is that the gains are fairly small...and very hard to gauge on the track, because of the almost endless variables that can change from run to run......but they can easily be seen on a GFX or similar device.....

MafiaRacers-Sorry but your knowledge and statement is UNTRUE.
It does not hurt ALL NIMH.
I wouldnt do it to ANY brand Panasonic
The Sanyo 3000H's didnt like it
The Sanyo 3000HV's LOVED it.
1st generation GP3300's didnt work well with it.
2nd,zebra and SP GP's all LOVE being DeadShorted.

In offroad guys I cant say you will notice a difference unless your THAT good.
In 1/12th scale I can really tell a difference and in sedan.

It's all about how serious you are and if you have the experience racing to even tell the difference.
My stock packs are KNOWN for having tons of punch and work great.I lost about 17-23 seconds of runtime and I could afford to do that in Stock.
I wouldnt advise it for Mod sedan or 1/12th scale.

Hey Guys.

I have been dead-shorting for about 6 months have not noticed a great loss in runtime, maybe 15-30 seconds like texracer said.

I run 2wd mod and 4wd mod offroad and i am still having HUGE runtimes left after races anyway.

i think dead shorting gives more punch for the 1st minute but then drops off alot plus it is bad for the cells

I notice my batteries last longer and stay more consisant from dead shorting. Of course you have to do it right. Plus you need to do this when the batteries are new and keep doin it from then on. I race Stock and 19t Touring. And it works great. I wouldn't do it for 12th scale or Mod Touring.

Anyways, you get different answers from different people. I started it because I know this one oval racer and he told me to do it. So I started doin this. I trusted him because he's one of the best in the country. And his battery packs were just awesome. And we all should know how much oval racers are chasing down every little bit of speed they can get. And how hard they are on batteries...

Default Dead Shorting

I would say yes, only if used on the GP3300s.

Everybody has different equipment and their own system for doing things. I have been happy with my results to keep doing it.
