Thanks Dude, good to know.

[QUOTE=promatchrcr] I have heard they like deadshorting but when they are already 1.20+ how much higher can they go?


I wouldn't dead short these latest date codes the loss in runtime and higher IR's aren't worth the gains in the voltage, which is minimal.

Yeah, you got it...thanks man. The cool thing is on the cell master once you set the temp cutoff it really doesn't matter what peak detect you use since it will stop at the temp you set anyway. That the great thing about temp charging. Keep in mind thoguh as Arun (Nexus Racing) has stated the temp will continue to rise for a short period after the charge has stopped. I usually set it a degree or two under where I want it to be as a safe guard.

Again that's what I had heard but regardless I have no intentions to deadshort.....Like I said the numbers are already excellent why mess with a good thing?

Promatchrcr,

I agree with you I just wanted to let folks know that these new cells don't need deadshorting,seems there always comes up the discusson, deadshort or not? when new cells come out.My latest packs of 1.22's are just plain awsome,kinda like having a 5th cell.which is what we 4 cell guys needed.the snowbirds should be crazy this year,there's no telling what we will see down there,1.25's or better maybe?

Yeah no problem, I agree with the current crop of batteries and the 4 cell oval classes will be interesting. Now that IP has entered the game and hopefully GP will respond to the latest IB cells it is beyond me how they can get much better....as the saying goes : BIGGER, FASTER, STRONGER....when will they max out the voltage these things produce?

what i noticed with linear and step charging yesterday was that when using a linear charge, i can reach my temp cut-off which means my packs are hotter at the end of the charging cycle as compared with step charging, wherein my packs cut-off via "peak detect" , and the temp is only at 45deg.

any thoughts?

You are right on...I always get a lower temp when using the CTX charge. If you use the battery heatsink it will be even lower...I only use it when it is very hot outside. They need to get some heat in them just not a alot.

I know this has been asked a thousand times,why doesn't pro-match go with 35 amp matching?

i am sure promatch will go to 35A at some point. But using 30A number are probably more common right now.

i run them in 1/12 and have plenty of punch and runtime. you are getting 1.21 at a 5amp charge. so i would not even go to a 6amp. i would do as everyone says and gear one tooth lower. i have run them in stock and mod with a lrp/neo combo and neither had any problems with getting soft.
