i dont think u damage that cells, if u did, its very minimal. mine was worst, the solder melted and cells got seprated from the pack. u should be fine

dakrat

almost every cell manufacturer/matcher out there dont reccommend this procedure. there too many topics about dead shorting in this forum. do a search

axel

thanks , what a relief.

centax error!

it's sort of a disclaimer... you will find alot of different opinions about dead shorting. If your not sure about what your doing don't do it.

Do you guys store your packs after traying them down to .9v? And before my heat should i tray them down to .1v then charge them? How does this plan sound for stock racing?

dakrat

tray em just before charging. .1v eehhh its up to u

axel

Help !!!!! my pmr cells now charge peak at 3330mah??!! they used to charge to 3800mah?!! well this might have been do to that i trayed them down to .9v for the first time...but still 3330!!?? maybe i should've trayed down to .1v or deadshort them to get max. mah...is this permanet?!!!

centax error!

post charge settings?

dakrat

u got it the other way, dead shorting will not help gain MAH.

axel

what will then?? this really sucks if my cells stay like this

axel

ch: 5amps
disch:10amps ( i know weak)
peak sensitivty: 5mv/c
dsch. volt.: 0.9v/c

then i trayed them to .9v,

first time they chraged at 3700 range then later to 3338!!

I have a duratrax ice

axel

Help??? i think i might have permantly damaged my cells...but how this tray do that?

centax error!

Your setting seems ok basically and I assumed you trayed packs to .9v before charging and discharged them to 5.4V/pack using your charger after every run after it has cooled down .How many times do you charge pack in a day? The MAH will reduce slightly as the # of charge increases per day but will get back after you give them a rest and charge again on the next race. Also try lowering your cut off v on the smart tray and see if the MAH increase. Does this happen to all your packs? I really don't mind what the MAH #'s says on the charger but if you're really crazy about the MAH look for someone who has a T35 or GFX and give your pack one cycle and take note of the runtime ( discharge time). Your pack is not damaged if the #'s are close to the label on the cells.

axel

well i'm worried becuase this was all within 2 consecutive cycles...i worry alot about mah beacuse it shows me how much longer i can use these cells...i cycled them 2 times today and 2 times yesterday...i hope your right about having them needing rest.

centax error!

don't cycle your packs if you don't really have to. Again don't be confused with MAH and actual runtime. It's the run time that you should worry about. I charged all my packs maximum of two times per day and my good packs only ones.
