Bull Crap Dave
I ask Danny ...
Why use C-Rating on SMC products if C-Rating`s are not use full or accurate for rating a pack ?
You can`t have it both ways Dave, condeem another company for using C-rating and then use it yourself ?
All I got back was "I miss the point"....
That`s not a answer Dave , its a dodge ......
Just so everyone knows ...
The "point" of this thread is to condemn that other company for doing just the same as SMC has been doing all along ....
O-Lookie !
here come some more insults...

Reading comprehension is truly not your friend.
Danny NEVER attacked other companies for using C rating, he was just warning people that some companies are using FASLE number and telling us HOW SMC gets their numbers.
So consumers are paying more for 35C packs that are actually 20C packs.
I don't know about you, bu I want to get what I'm paying for.

Danny NEVER said or gave the impression/implication that rating lipos for their C-rates is bogus. He simply and to the point I might add, said that SOME COMPANIES ARE BOASTING BOGUS C-RATINGS. Stop smoking pot brah while you still have a few brain cells left......GEESH!!

This is why I only buy SMC lipos for my TC5

when I came back to RC after 5years of abscent I was confused with Lipo, BL and all that but this is how I understood the Lipo and I am sticking with it.
C rating w/Mah = as same as Mah w/ 1.2V advertised by Battery manufactures (Sanyo, Panasonic, GP..etc)
then Pack should be indivisually tested and labled by RC companies (SMC, Orion, Trinity etc..)to show true racers freindly numbers. (SEC, AVE V, MAh, int)
in NIMH days I wouldnt buy a pack that only show 3300GP 1.2V sub-C.
then why would you buy a Lipo that way? cause it show 5500/55c ! ?? from non RC manufacture?
the only RC company did show the meaningful numbers was SMC and I bought a pack and very happy with it.
here is the nembers on my pack in case you never seen them.

Danny i am very curious on how you have your gfx setup when you cycle out the packs.
I have 2 5200 35c batterys and here are the numbers from them
i charged them at 2c which on the gfx
discharged at 35 amps down to 6.0 amps
here are the numbers from my packs
#1 561s avg voltage is 7.30 IR is 8
Mah is 5454
#2 563s avg voltage is 7.28 IR 7.8 Mah is 5473
I just want to know if you have anything different setup on your gfx so i can correct it to check the numbers again.

Danny, can you comment on a rumor I've heard. Some of the LiPo cells include "preservative" chemicals that are there to help store the battery. During first few cycles the chemicals go out or react with something. That's why it is advised to make few first cycles with small currents.
Is this just a rumor or is there some truth in it? Should we cycle LiPos the first few times with small current? Of course if the pack-maker does it then there's no point but I don't think most of them (cheaper ones) cycle packs.

the pack is at room temperature.... house thermostat is set to 65 degrees
i have a deans plug , a wire coming off each side of the plug one for red and one for black. i have the big clips on the gfx on the wire and i also have the little clips on the wire as well... not touching the big clips.

Never heard of this. We typically use our packs at high discharge rates right out of the box. I know some of the flight people do some breaking in cycles but Lipos have evolved and I don't think this is needed.

To get readings like we get you need to have your voltage sensing leads on the packs power leads. You could remove the shrink on the female connector and clip your voltage sensing leads on the connector. If your using big clips make sure that your GFX is pulling 35 amps throughout the discharge as there might be resistance that will keep it from discharging at 35 amps.
