Hi i am just getting into the oval scene was wondering what 3200 lipos are people running and why you recommend it thanks guys

looks like alot are going to the the smc right now. orion discontinued there 3200 or i would say to run theirs.

How long does it take to charge these 3200 and how many battery do you half to have to make a race day?

stesh,

our series has been running lipo since February in All of our classes, and we started with them the last couple months of last year.( around Oct.)

Most of our racers only have ONE or TWO packs total.

Depending on the racing program time schedule, charging and re-charging has not been an issue between rounds (We run an hour to an hour and a half per round)

Personally, I charge my 3200s at what's known as a 2c Charge rate (3200 mAh x 2 = 6400 mAh or 6.4 amps) At this rate, the battery will charge to 90% in about 15-18 minutes (running 21.5 class) and get it's full charge in less than 30 minutes.

My son and I run 2 cars each, so I'm bouncing between 4 cars and 3 chargers..so I also have 2 extra packs incase I screw one up, or forget to charge one (Pre-Charged in a box...just waiting)

I have been running 21.5 lipo since late last year, up until next week I have been running the one pack of the orion 3200, Like SWtour I have been charging @ 6.4 amps and have had no problems getting them charged and running the speeds of the fast guys. I just got a SMC3200 because they are available, not that I need it, guess I got more money than brains.

smc 3200 charge at 10-12 amps takes about 16 minutes to charge them up!

And you guys wonder why the're are expolsions and fires!!! :rolleyes:

Been charging at 12 amps since I started running lipo and have yet to have one go up in flames or any other crazy things that lipos do and yes I have played with my lipos getting them up to 9 volts.

I guess you dont mind spending money on batteries, although the lipos cost a few dollars more then nimh. Oh and if you keep charging them that hard you will most like set one off so keep a pail of sand ready to slow down the fire. Personally I like to keep my lipo's usable for at least a year. Of coarse you might be telling use a big story.

You can ask anyone I race with I can get my batteries over voltage whenever I want to. No I don't mind spending money on batteries, i'm very fortunate to have a job that pays me very well and I can afford to do it. If I was racing on a shoe string budget I probably wouldn't charge them like that. I have been running the same battery for 4 months now and it style cycles with great numbers. The smc pack I have doesn't get charged that hard on the advice from danny that they don't need to be charged that hard.

Hi i am just getting into the oval scene was wondering what 3200 lipos are people running and why you recommend it thanks guys

To actually answer your question you should run whatever is legal at the track or races you plan to be at. Some tracks will be SMC only, some any roar legal 3200 and others may do something totally different. If it is any ROAR legal pack then it's toss up between the SMC pack and the Trakpower 30C pack. Personally, I'd go with the SMC pack because many tracks are specing that as the only pack allowed. Then you know you have what you need to race at most places.

Thanks everyone for the help.

I just have one more question. I am a fix income racer and I have a victor charger and Integy charger, will these charge the lipo?

What kind of integy charger? If you are looking to get a gfx with lipo I have 3 for sale now.

The integy 16X512 not a lipo charger. how much?

Well... if you show up at the starting line with more than 8.44 volts, you'll be shown the door at any of the BRL series races.

Well I don't plan on running any BRL races cause I don't live in the midwest. And would you look at that we have the same rule here in florida. 8.44 volts but most of us in florida also realize that 1 or 2 tenths of a volt doesn't make a difference. :wave:

If thats true Why are you Overcharging your packs???

Because I like to overcharge them and bring them down to 8.44. Not have it cut off at 8.44

Guess you missed the sarcasm in my post.

I know why your doing it and the word circumventing comes to mind.

By the way " 1 or 2 tenths of a volt " makes a legal 8.44 volt Battery into a 8.54 or 8.65 volt battery.

That's right Lee but some people just can't play by the rules.

If my battery is at 8.44 volts when I go through tech and put it on the track it doesn't matter.

I guess the "Letter verses the Intent" of a rule would fall on deft ears.

Getting around a rule is more important than meeting the intent of the rule.

What happens if there is an incident with your battery, say inside a building that a race is being held in. And the race director knows you are violating the intent of the rule and the owners of the building investigate and finds out that the race director knowing allow a practice that violates a know industry standand. Do you think the owner would allow racing to continue at that faciltiy. What would happen to the race director if the Fire Marshall got involved at say a county owned faciltiy and it was discovered that the industry standard was allowed to be ignored.

For the good for our hobby, it would be a good thing to not be too proud and vocal that you bypass the intent of saftey rules.

If I where running a race program and I was made aware of someone working around this rule, I would ban them from any event that I was running period. just my .02

Sort of like putting drunken party photo's on facebook and trying to get a job representing a company.

Well Ron I hate to disapoint you but the tricks I learned with these batteries were taught to me by the same people you and I race with and against. I just happen to be the one that will admit to doing this so I guess I am the bad guy but the guy next to you doing the same thing that doesen't say it out loud is OK. HAHA what a joke.

And we wonder why it is so hard to get new oval racers... or why some start and then quit right away....

Keep it up 18TLateModel... you'll be racing by yourself at some point.

actullay if i found a person doing this at a race i was running i would ban that person. they may sound harsh but someone has to be the example for the good of the sport.

Exactly - out the door and don't bother coming back.

Well thats good also because I have been racing pan cars for about 6 months now and I am the new guy that you are talking about but i'm not going anywhere so love me or hate I don't care. I'm still gonna be here. Now before this discussion goes any further. DID I SAY THAT I RACED MY LIPOS OR OVERCHARGED THEM TO 9 VOLTS WHEN I AM AT THE TRACK. NO I DID NOT. I STATED THAT I PLAYED WITH THEM TO SEE WHAT I COULD GET THEM UP TO. I will get them to about 8.5 to 8.55 and drop them down at the races. If you think that is giving me an advantage your wrong. I just like watching people freak out over nothing. Cause the more your worried about what i'm doing the less you are working on your ride to make it faster. That is my advantage and the end of me rambling on with this topic.

Thanks Matt:woohoo:

I ran 21.5 last week with a fellow racer charging the pack for me. I went up to race with 8.40 every round and went a full lap faster then anyone has gone there in 21.5, I ran the Orion 3200

All over-charging does is make up for a bad set up.

Yeah -- but it's "monkey see, monkey do" ya know... guys seeing another guy doing that crap that goes fast and then everybody's doing it...

Best to shut it down right away.

That's why I'm glad the BRL has the rules they have -- 8.44 volts at tech, AND the battery cannot be any warmer than the control pack at the room temperature.

So in short why dont they set a more strict rule about batteries/voltage to stick to and if your caught then your done racing at that paticular track/event

Well... I'm sure part of the problem is most tracks don't tech cars every round. When I start racing in the late 80's, the tracks teched every car, every round. I haven't seen that done in the past 10 years.

So even if you make a rule, if you don't tech cars regularly then it's not much good. It ends up being a "gentlemens agreement" and those that are not gentlemen won't follow it.

So in reality same style driver same experience level driver same equipment a rule bender/breaker is always gonna win thats just BS IMO if ya cant win by racing the with the rules provided i would think you need a place where cheaters/rule breakers are accepted

lol Yup Preston even on carpet with all the voodoo Matt is still 2 laps off Tom

Hey focker there was no voodoo at the carpet I put my car on the tech table 3 heats before my heat and left it there. You can't out run Tom either whats your excuse.

closer than you are. 1/2 a 10th off

Lets see... 3 heats.... maybe dropped .000000001 Volt in that time. ;-)

:freak:

To answer your question newrcguy2008, I run an Orion 3200 pack and a Peak 3200 pack. I charge at 3 amps and have lots of juice at the end of my runs. Buy the pack/s that you can afford or that are a good deal. They are all good and you'll love the convenience of the LiPo era.

Forget about the extreme charging procedures that you may observe other doing, and use the manufacturers recommendations.

Happy RC'ing

18t i was not directing this at just you thats why i said any person caught. all that i'm saying is should there be a fire and the fire dept. found out what was going on they could rule this as a suspicious fire and could end up with 1. eviction from the building 2. a possible fine 3. insurance co. not paying for damage. now i no this sounds drastic but it is possible that this could happen and be very damaging to the sport especially in the area it happened. thats why i say the race director/owner should not allow it if they see it.

Its all good.

For what it is worth... the annual 'IIC' Vegas race a couple weekends did this for tech, and seemed to work out good for them:

http://www.rctech.net/forum/4759034-post1427.html

No matter what, we have to all be concerned with safety, and I am sure we all can agree to that. So from now on Matt I will have a webcam in your pit area. :wave:

I'd have simplified it farther than Scotty did and say if you fail temp or voltage you can go back to your pit and wait for the next round.

I believe more and more races will be starting to follow that rule... Roar did it at the Paved Nats with zero tolerance.

How do tracks set the max allowable temp?

And here is a little information I have been seeing:

Some chargers seem to push the 8.44 voltage setting. Last race we had, Sam Ledford had a machine he sent back to have converted - pitted right next to me. He took his car up for the 1st heat and the battery read 8.46. We had to change the calibration to 'trick' the machine to not go over. We also had a well known racer at the carpet Nats (Hopeton Williams) have three machines all stop at various voltages: 8.38, 8.42, and 8.46. In cases like this it makes for tough calls. Some chargers are spot on 8.40 each and every time... Racers in practice should check with the track meter each time they go out to be safe - so when the first heat rolls around there are no issues. Then you can be safe to say no grace, etc. Everyone is learning in the positive direction.

And we did have a LIPO fire not long ago at MTR. It was not from someone purposely overcharging, but from a mistake on the charger. Granted it was not in a LIPO sack but still scary. One of these will change eveything. I am not sure if anyone has seen a LIPO fire in a sack but I hope they work.

Sonny I believe (I might be wrong) is having a pack in tech and setting a max temp above that, that is allowed. Batteries will be checked with a temp gun. Vegas was 110 degrees max allowed before racing...

I'd have simplified it farther than Scotty did and say if you fail temp or voltage you can go back to your pit and wait for the next round.

Thats a tough way to go though. I know that the meter was avaialbe all week during practice and guys were teching them selves to make sure their chargers were OK. Some found out that those small voltage leads on the GFX mean it goes to 8.50 and not 8.40...they found out quickly to use them! Also there was NO 1 minute grace for anyone that was over temp or over charged (which we never needed anyway). If you failed on one of those there was no holding up the race...period.

There were very very few people that had to blip the throttle in tech to pass. Chargers do weird things sometimes. I had my packs at 8.42 all week on the tech meter using the same charger. Go up for the main and it is bouncing between 8.44 and 8.45....I changed NOTHING from what I had been doing all week. Should I have been sent packing for that? No way was it my fault. I could see maybe after the 2-3 time sitting someone down for a round.

I think all in all 99% of guys out there are NOT going to take a chance on it. And the 1% that does someone in the pits will know about it and let someone in charge know. We need to police each other as much as Tech does.

110 is a good temp as if the case is at 110 then the actual cells inside are 10-15 degrees cooler usually. I know in Vegas I had mine at 110 when I taped them in the car and within 3-5 minutes when I got to tech they were down to 90-95 degrees. Thats the general drop I have seen as they will be close to that when they come off the track after running too.

Sorry... wrong thread

Thunder, the call is easy, from a tech stand point, it does not matter why, only that it is. period, it can be that simple. rules are rules. It is not techs, race director or race promoter function to figure out why. It is the racers responsibility to meet the rule. I was .1 oz under the weight at the Nats a couple years ago, DQ'ed, my fault.

We saw the same thing at our track -- a couple of guys were charging with the updated GFX without the voltage sensor leads connected -- the pack would come of at 8.54 volts, even though the display was reading 8.40.

Took the same pack and charged it on a Checkpoint 1030, and it came off at 8.40.
