They also said it is not needed but can be done every 30 discharge to make sure the cells are again full together at 100%.
Thanks alot! I hoped it was that simple. I was considering going with the scorpion but this seals it. I would rather not carry use dedicated li-poly chargers. Since we will still be running several ROAR events this year that would be more stuff to tote.

Happy to report that my first race outing with the the Platinum was a complete success. There was an obvious voltage improvement over the usual 'budget' (I guess $50-$60 packs are 'budget' to some people) packs that I usually run.

The weight loss for my TA05 was also welcomed. While running 19t sedan, I only used about 1800+ mah each outing, so theoretically, I could have run at least three times before recharging the pack....but I didn't try it.

The charger nearly charge the pack completely before my next race, but it didn't matter since the voltage was the same whether the pack was full or almost full.

This was definitely a turning point for me with R/C. Dischargers, discharge trays, matched/unmatched packs, battery of the month, battery cases filled with 6-8 batteries(with only two really race worthy), it all seems so pointless now.

I am thoroughly impressed with this battery.

Thats good to hear Darkseid! I hope more people read this thread and find out for themselves how good this battery really is. I've been ranting to everyone who will listen, these batteries will flat out put an end to the stupid battery wars! When I get asked about the high $$ of this batt, I say look at it this way, a serious racer needs to buy 3-4 good packs probably 2x a year (every 6 months) to be competitive. Thats $150-$200 for mid matched packs. So, at the end of the year you've got around $300-$400 worth of batts constantly being overturned.(again competitive racers) Spending just $280 for 2 li-po's and be done for maybe 2 seasons of racing is worth it for me. Gotta wonder what the matchers, manufacturese are thinking right now, I'd love to see them squirm around a bit, instead of us everytime a new battery comes out every month or so.......

Sold my tray, Nimh chargers and bought another Platinum and another ICE...my box is emptier and I go faster with less hassle. Gonna sell my other PS, since I can easily charge two LiPos at the same time at 4.8 with one 10a PS...

Just have a few stick packs and a 20A Integy discharger for Roto-Starts.

Life is good...Spektrum, Novak BL and Platinum.

Scorpoin does have LI-POLY for cars. Stormer sells them on line. Scorpion claims that there charger and battery combo balances the battery and charges better. the have a ton of wires and it all looks very impressive. My bet is it is all snake oil and voodoo to sell there packs. They use the same cells. I dont need to carry any more junk than I alreay do. Having 3 chargers for LI-PO and 3 for regular packs.

Yes my local track allows LI-POLY for club races. Right now we are indoor on carpet but I am looking forward to going outside in a couple of months. We have a dirt oval and an off-road course. We are running sprints open class. I have run my sprint with a GT7 and Checkpoint 9 turn and it is HATEFULL! I am looking forward to runing 3 heats and a main. If the 4800 can supply enough juice for 5 min main using a low turn brushed or a gtb/5.5 then I am all in. When your turning 4.1 second laps I am worn out! I don't need to run 15 or even 10 min. I would rather have less weight and just enough pack to run my main safely.

Yeah, why wouldn't they be? When we hold sanctioned races they aren't allowed, but I'm talking about weekend club racing.

When things get so serious around here that I have to start worrying about what will be "allowed" at weekend club races, is when the track will lose my money.

Thats easy, their thinking:

"We have to come out with a LiPo of our own" (good thoughts)

-or-

"we have to convince people these things still aren't safe and cost too much" (bad thoughts)

-or-

"we have to make sure these things never become legal for racing" (worse thoughts)

But since I've already been slapped on the wrist by a roar rep here who insist that big manufacturers have no say in what is/isn't legal, I guess we all don't have to worry about that last one huh?

It would be cool to make 20 min races with 5 min heats and 10 min semi.

Stateline R/C the dirt oval and off road are in Fremont Indiana. The property line is litterely the Michigan state line. The east property line is the right of way for I-69. We are inside for the winter at our carpet track in Angola Indiana, which is about 6 miles further south down I-69. We hosted a MARS race last year and are looking forward to hosting more events this year. Check it out at www.statelinerc.com. There are a couple of special races coming up.

Is there such thing as storing these at too low of a temp? I'd rather store these in the garage but it is unheated. Thanks.

This has got to be the sweetest most advanced competition speed control ever built to date!!!

I have one with the U-Link (PC software connection). It lets me adjust parameters that one never dreamed of on an ESC.

This includes fine tuning the voltage cut-off which comes in handy especially when running multiple or higher voltage Lithium pack formats.
