View Full Version : Should we go to 6 cell voltage?
gezer2u 06-25-2007, 06:54 PM I really don't want to see posts about which one is better, but info on why you feel this would be good or bad. There are plenty of threads to discuss the upside or downside of lipo's, so please don't do it here. Remember that everyone is entitled to their opinion, so please be courteous.
One thing I see is by going to 6 cell voltage, either NiMh or lipo, we can use the same batteries to race other types of chassis and vise versa. Let's look at the bigger picture. Going to 4 cell was great at the time, but now we need to go back. To keep the speeds use BL motors. I truly believe that this would attract more racers to oval and help the other types of racing by allowing the oval racer to use the same battery. This wouldn't have to happen overnight, but should we be working towards it. I know that Offroad and dirt oval are using lipos, so you would be able to buy a car and go racing.
What do you think?

Discussing which is better and which is good or bad is pretty much exactly the same thing.
It makes no difference what voltage we run as long as we have motors that give us the right speed for each class. At the moment we don't have that yet, but I'm sure we wil if that is the direction things go.
It would be nice to be on the same page as the some of the other classes. Though keep in mind there has been talk floating around of touring switching to 4 cell for some time. Who knows now with lipo though.

What do you think?I don't know if going back to 6 cell is a good idear, the batts now are so unstable that if you were to go to 6 cell it would cost you twice the money to run and with with added voltage the cars would be out of control that is why the 4 cell racing came into play to slow down the action .Just my 2 penny's

I suggest going to Lipo (2 cell pack) which is like racing 6 cells and
raise the min weight of the pan cars. :thumbsup:
TBRC1 06-25-2007, 08:06 PM At first I did not want to go to 4 cell oval but after a while I came to like 4 cell. If we were to go back to 6 cell maybe it would be better for the more experienced racers. Thus leaving the 4 cell for the newbies so they can have more control over thier cars. If 6 cell were to come back to pan oval it would be good for me I'de just make my 4's into 6's and go for it :thumbsup:
bologna 06-25-2007, 08:38 PM i have no problems with 4 cell.. lower cost and they swap from my oval car to a 1/12th road car with no problems....
i also know i would never run 4cell oval packs in any other form of racing i would just have a 4cell box and a 6 cell box for different needs

This is something that I use to LAUGH at - when DIRT guys worried about making their OFFROAD packs into 4 cells..like it was going to HURT THEM.
When I wanted to run TOURING or DIRT - I'd take my WORST OVAL Packs...and make them 6 cells - and guys would accuse me of cheating cause I had rip on them...(EVEN at times my cells would be 2 generations behind them)
MOST oval racers who have been around more than 4-5 years know we went 4 cell to slow the cars and help car control. This wasn't the only thing being worked on at that time to serve this purpose, but it was the one that made the most economical sense for OVAL racing (We looked, and surveyed the numbers of CROSS over guys too...and the numbers were too small to worry about upsetting the cart.)
With the LIPO's, since you can't drop 2 cells to cut the voltage to 2/3rd of a 6 cell pack - we had to go back and look at MOTORS as the speed controlling feature.
With the NEW Slower B/L motors coming - running 2c LIPO or 6 cell NIMH could be done at similar speeds, especially at a club level..and still be able to have a controllable car.
The downside to me w/ the 6 cell is the weight of these cells - and when you put 2 more of them in the car what's a pan car going to weight? 50 - 51 oz? That starts getting even harder on tire wear, etc...and makes the battery have to work a little hard... But, again for club racing I think it could help oval a lot by not having to have the 2 different batteries for the 'weekender' OVAL racer who may want to do OVAL today - and OFFROAD next week and TOURING the following week...and I'm sure in certain markets these drivers exist.
I have told guys in my series that in the classes I'm going to allow LIPOs, I would consider letting them run 6 cell at least once to see where they power up with the LIPOS...and this would let guys try the NEW Slower motor speeds on the higher voltage to see if they would be interested in that type of class.
Joey 3 06-25-2007, 10:13 PM I 'd keep four cell packs. It helps keep the cost down and the cars are still plenty fast. Plus I think alot of the cars are set up with 4 cell battery trays anyway.
katf1sh 06-26-2007, 10:20 PM no more tha 6 volts
going to a pack that is the length of a 6 cell is not a good idea. new battery trays
if it's not lipo 6 cells cost more to buy
6 cells are heavier,tire wear
6 cells have more voltage..90% of the oval racers can't hold a line with 4 cells voltage now!
i'm very happy with 4 cells and the current crop of motors we have ow.
i would like to see the 17.5 motor become the new 4 cell stock class the 13.5 is way faster than the 27 turn brushed motors but it's a nice step up from stock.
we need a slow class for the novice racers or we will soon have none.
adding another 2 volts to our cars is not going tomake anything easier..
i could care less what the open mod guys run..let them run what is the fastest..who cares? they all get free packs and free cars and motors anyways..let them showcase all out speed..but for 90% of us we need to race door to door and have fun rubbing fenders..you just can't rub fenders with a avg joe oval racer at 70 mph...
controlable speeds...cost control......10 cars on the same lap.....that is fun.....
McLin 06-27-2007, 12:05 PM In my opinion, classes need to be structured and controlled by the motor and not the battery. With today’s batteries, they are controlled more by who has the better batteries and who can keep buying fresh ones. I would have to go back to the days of the blue Panasonic’s to remember a time when I heard so many complaints about their packs not holding up as they should. This is not “control”; this is giving the “power” to those that can continue to throw money at it.
LiPo batteries and Brushless motors are not perfect but they do seem to be more consistent with regards to voltage and performance than we have ever had available to us. Plus, we all know that the run time of a LiPo pack is just not an issue. What I think is going to happen and what is being worked with now, is converting to the LiPo’s and having Brushless motors designed for the classes.
A motor is being designed and tested as we speak to use the 7.4 volts of a LiPo pack but run at a Stock speed. There is already one that has been tested that will do the same for the Spec class. Plus the Mod guys have existing motors to choose from that will cover any speed that they can handle.
By far, this seems to me to be the most practical approach to electric racing that has ever been. For once we can plan on a “very” limited amount of batteries that we need and an exceptionally long time between the times we will need to replace them. Along with that; you can plan on what motor to run for what class and be reasonably assured that you will have equipment that is at least close to everyone else.
To me, this is a win, win situation. The electronics are in place, the batteries are in place and the motors are almost there. Again, in my opinion, to continue to work with NiMH batteries is just throwing good money after bad. It’s time to move on.
BullFrog 06-27-2007, 12:24 PM This is the same discussion everywhere.Since the 13.5 is just right for TC for On-Road and too fast for oval - Simple make yours(oval the 17.5) as the racing standard. If your waiting for ROAR to make some decisions they won't for awhile.The local clubs under a ROAR santioned event(level 1) as long as you post it in advance can run what you want.If you the oval guys want to run the 17.5 as your stock motor great -post it and run it.But waiting for the national organization to help you along good luck.Take the lead post what your club or series is running and go for it. Our on-road series is using the 13.5.Your other issue is lipos there here and coming by many other manufacturers. Unfortanutely there voltage is higher than the sub c's. You go with the 17.5 and the lipos.There is no correct way to do this just experminent and the guys out there post it(and your the same ones everywhere) come up with want you want to do.
Andy Koback 06-27-2007, 01:06 PM I agree with katf1sh!!!
brian0525 06-27-2007, 01:35 PM I agree with katf1sh!!!
6 cell voltage not actually 6 cells!!!!!
I would to if we were talking about running 6cell NiMH cells but that isn't what we are talking about really it is Lipo's. If you have slower motors to match the voltage then speed isn't an issue either.
I like what we have now just fine but it won't stay that way so I am ready for whatever comes next!
swtour 06-27-2007, 02:37 PM ...2 things that I'll quote:

I don't think MANY Oval guys wait for ROAR to do anything, nor have they for several years. We look for a direction that is good for the racers we have, and there is a group of us that also try to look for things that 'COULD BE' good to help introduce OVAL to New racers.

On this issue, as I've tried addressing it to several different people - this is something I've proposed for 'CLUB LEVEL ONLY' type events where there could/would be a decent chance of drawing NEW interest.
ALLOW 6 cell batteries to run (Emphasizing, that they are NOT the Preferred battery of choice) and let them run WITH a LIPO 3200 based Motor combination. ie: If a guy wants to run...and only had 6 cell STICK packs - and he wanted to run the equivilant class to 4 cell STOCK - right now, I don't believe there is really any combination he would be able to run and have close or similar speed (MAYBE an old 5d motor - IF you could find one)
But with the structure coming forward with Brushless Motors and varying the speeds of them...the motor desiged to run equal to 4 cell STOCK speeds on LIPO, whether it be a 25.5 or what ever that motor ends up being...there should be virtually NO advantage to a NEWBIE racer using a NIMH battery vs a LIPO battery to introduce him to the racing.
Hopefully from getting him to set his FIRST CAR on the track - a 'local director' would be able to either work with the new racer or put him in contact with knowledgeable racers who would be able to then point them in the right direction (WITHOUT SCARING THEM INTO BUYING Super HIGH END, TOP LEVEL, NATIONAL WINNING Equipment)

I was pointing out where Katfish was saying they are heavier as a reason not to go to 6cell voltage. For someone to try it out with 6cells to see if they like the voltage difference would be no big deal in my eyes.
The Jet 06-27-2007, 04:26 PM 6 Cell VOLTAGE??? In a nutshell, HELL YES!!!
1 battery to power all forms of racing equals more racers.
Use MOTORS to regulate speed.
Lipo's are way lighter, so you can throw the weight argument out the window.
Cost is just something to bitch about...We'll all do what it takes anyway.
Let's see...Buy 1 pack that will run your...
1; Stock car,
2; Mod car,
3; 19 turn,
4; Brushless...
5; Touring mod,
6; Touring stock,
Hell, even mini T's run 6 cell voltage.
IT's A NO BRAINER!!!!!!!!!!!!!
gezer2u 06-27-2007, 05:44 PM Do any of you think it would bring in racers from off road, dirt oval... etc? No one has posted about this aspect.
McLin 06-27-2007, 07:21 PM I think that is a real "iffy" "Maybe". I look at that in the same way I would look at.....would it cause any of us to run off road or TC?
swtour 06-27-2007, 07:38 PM I think that is a real "iffy" "Maybe". I look at that in the same way I would look at.....would it cause any of us to run off road or TC?
EXACTLY - if you are NOT an R/C OVAL Racer - will you become a R/C OVAL Racer?
I use to say NO! But when the METRO track in Bakersfield reopened this year and some of the regular OFFROAD guys who had NEVER seen, or touched OVAL cars were given a chance to come run 4 cell STOCK on the high banked CONCRETE OVAL - some said they had NEVER HAD SO MUCH FUN IN THEIR LIVES with a R/C CAR.
Now, we put most of these guys in USED L4's and L3's with USED MOTORS, and USED BATTERIES to get them on the track. The ones with the budget started upgrading right away - the others are doing just fine w/ their entry level rides and having a BLAST.
By doing it with USED stuff - they didn't try to convert old OFFROAD STUFF over - who really does that anyway? And - Ok, so I have a couple 6 cell packs for my buggy or truck and I want to TRY oval with a USED or BORROWED car this weekend...
So I RE-LAYOUT my 6 cell packs into 3 4 cell packs (Marking which pack I split in 1/2 so I can reassemble them later back the way I took them apart. To turn these 2 - 6 cell packs into 3 - 4 cell packs would take what...5 - 7 minutes? Then at the end of the day - to turn them back into 6 cell packs...another 5 - 7 minutes (OK, I'll even give you a full 10 minutes)
DID THE OVAL RACING HURT the OFFROAD PACKS? heck no.
WERE the OFFROAD PACKS 'good enough' for the OVAL? Probably if this was a NEW to OVAL guy - there were probably JUST FINE~
