Re: SMC
 

I'm pretty sure Keith Mackrill was using SMC cells to win Mod Tourer class at the Qld Titles , against Abbott , Cookie etc, so they can't be too bad....:) :)

My question is also how can you get a dead cell from new? I never had that problem with cells when I was matching Nicads. Their quality control can't be real good if they send out packs with a dead cell in them. Interestingly my SMC matched packs have considerably less run time than an unmatched pack I have, but higher voltage...makes you wonder how mauch they have been zapped

Re: Re: Shorting GP3300
 

Please send me a link to this thread or just explain to me step by step on how this can be done. I currently have unmatched gp3300 and a cdc v6 charger.

With dead shorting how much voltage roughly should you expect to gain and same for mah lost?

Is it just a little or significant change? or depending on how long you dead short it for?

thanks

If you are lucky you may see a 0.01 increase in voltage with a 10% loss in run-time. If you are not you will see no increase but still a 10% loss in run-time.

There is nothing you can do to get the run-time back either, my advice don't deadshort.

The SMC forum is HERE

for information on dead shorting, and general battery care, a plethora (sp?) of information can be found in the SMC forum..

it is not that hard to find, and u would have had to go past it to get to teh australian forum.!

there is also alot of information that can be found on the SMC website.

Cell matching
 

Has anyone tried matching their own cells? Can this process be done using a CDC V6 charger?

You wont get far with a cdc. It won't charge single cells above about 3 amps.

If youre going to match, buy a Competition Electronics Turbomatcher 4/35. If you can get it sub-$1k you're doing well. And it wil stil only do 4 cells at a time.

The matchers all voltage treat their cells (zap them) and do some other cool stuff like cycle the cells several times to get a proper reading. Well, they should anyhow...

Moral of the story - just buy matched cells from a reputable matcher. I've heard good things about SMC (personal experience), Fukuyama (friends) and ZX (from message boards).

Or if all else fails, read the relevant rctech messageboard.

Yeah, ZX packs are very good.
Im running them now. John has the best customer service anywhere. and the prices are good

Is that what you think. HAHA i pitty you. And yes i do think that dead shorting is a must for any serious top level stock racer/

How many of us are really 'top level' I know you're pretty good but for most of us slapping in an extra cell wouldn't make us win at national level never mind 0.01V.

Deleted my post here becuase if I can't say something nice, I shouldn't say anything at all.

What I will say is that John, you really need to read up on a topic before spouting disinformation. SMC have their own forum on rctech which outlines in a lot of details the hazards, the benfits, and the methodology behind it.

Painy You have a PM dude!:D

All I am saying is that IMO a 0.01V/cell increase in voltage (SMC say 0.01 - 0.02) wouldn't make any difference to most stock drivers and the runtime loss could be an issue if you race mod as well.

I know I've got between 0.15 and 0.2 volts extra out of my packs (6 cell) by deadshorting. The non matched ones seem to come up by about .15, the matched smc packs seem to come up by about .2,

Makes quite a difference in stock.
