Well that's pretty much what I thought, the batteries all form one circuit, so no matter which cell is worse and where it is located, it will still bring the rest down with it.

I asked one of my customers to supply me a list of voltages/runtimes out of a randonm case of his shorty cells bought from me. These are not HV or handpicked or anything else-just a case charged at 6.0/discharged at 30 to 0.9 per cell and 5000 runoout-all STANDARD STUFF.

The results are quite good if you ask me-assuming you have finally come to the realization that the average cell is now a 1.157++ and really good packs are now 1.165 to 1.17++. Notice how good the runtimes are now too!! I cannot post all the results-but heres a cut of the top of the list.


432 1.171
432 1.170
427 1.170
426 1.174
413 1.171
413 1.171
418 1.174
432 1.167
425 1.164
425 1.165
423 1.62
421 1.162
422 1.166
424 1.168
428 1.161
429 1.161
417 1.167
415 1.165
419 1.166

and theres at least 26 more cells in the 410 1.160 range and thren a whole slew of 420+ 1.15++ too.

I hope this helps to point out that these new Shorty cells arent bad at all. IN fact for Mod and 19t ansd especially 12th scale these appear to be dream cells. Just dont expect the 1.179 to 1.185's too mcuh for now.

They look like pretty good numbers for loose cells!

I did a little research and this is what I found:

"Current is the flow of electrical charges (usually electrons) in an electrical circuit. When you hook a lightbulb to a flashlight battery, the current flows from the negative terminal to the positive terminal, always in the same direction. This is called DIRECT CURRENT. Electrical current from a standard household outlet changes direction 60 times each second (50 times per second in Europe). Because the current flows first in one direction and then the other, this is called ALTERNATING CURRENT."

Our RC CARS use DC. Thats why I think we should have our best battery in the negative to sustain the pack and lessen premature dumping. Because if it is the other way, if the worst battery is in the negative and it dumps, no matter how much is left on the other cells, you race is over, but if the best battery is in the negative, it will keep sending "electrons" over the cells that is low or have dump. And hopefully prevent DNF....ouch!!!! But , then from what I have heard, this is also the cause of "reverse polarity". That is why, it is absolutely important to have a truly "MATCHED" pack.This is my suggestion to folks like me who got just a few packs to race with, unlike Factory Guys who have almost perfect "matched" pack.

Maybe if you can get one of the electrical engineers to shed some light to this, will be greatly appreciated. Thanx

Hey Ray !!!!! You said in your post you "asked" one of "your" customers.......are you a dealer or store owner. If that is the case, can we get these "fabulously" looking shorty cells from you ???
