The GTB will work, i called novak and they said no problem. I have a GTB with 5.5 velocity motor, i am running Kokam 3200 mah scorpion pack, the ones u can charge in 20 mins. The car has more munch than i any NiMh pack i have ever run, and it never even got hot.
I hope that since Kokam is making them there will be a version that has the balancing charge port so i can charge them fast on the kokam scorpoin charger.

As much as I like new products coming out, this kind of products are going to start taking away from a lot of factors that make racing fun, like actually being able to "mess with" your equipment. Seriously, what is there in battery maintenance if you can't zap them, dead-short them, etc?

Umm...

Chassis setup
Driving
Tire choice
etc.

Even if we ran zero maintenance motors with onboard nuclear reactors, we'd still have plently of things to do.

The main folks resisting change are the matchers, who have been bilking customers for years into thinking that they need the latest and greatest cell matched with _________ matching process. Orion sees the writing on the wall and is doing this to make sure that they are in one of the top positions once Cars go Lipoly.

Brushed motor companies hate brushless and battery companies are scared to death of Lipolys. No more matching, no more turbo-matchers, no more zapping, etc.

No battery bars, no matching dischargers, etc.

The glorified 1970's tech we've been kicking around with for the last 30 years is finally in it's death throes. Bring in change, bring on the technology.

Watching companies squirm during the transition will be interesting to say the least. Just think of Kodak and it's near demise with the advent of digital imaging.

Yes LiPo can be fun for RC bashing but they will not make into RC racing for awhile. The only reason why they run as fast if not faster is because they have higher voltage. 7.4 vs 7.2 volts.


For those of you who think that all Lipos are equal your wrong. As more companies get involved in this new technology there will be improvements made just like nicads and Nimh improved over time. I have never tested Lipos buut I find it hard to believe that all packs perform the same.

How long until someone wants to make Li-Po mandatory because it's the only way to last the main without dumping. I just wish this was funny.

This seems a fairly irresponsible post coming from a company representative of a battery matcher, IMHO. If you haven't tested the batteries at all to get solid numbers, why speculate about a competitor's product? I'm honestly not trying to start anything but just don't see the point of posting what you did.

On performance. If you have a pack that can handle the amp load of the motor system you are running it will be way faster then sub-c cells. The IR's of complete LiPo packs are lower than a single sub-c cell, they have flatter discharge curves, they can have way more run time, they are way lighter...etc.

The main problem with LiPo is safety. NiMh cells are pretty idiot proof. LiPo cell are not. If you overcharge, over discharge, draw too many amps or short the pack out you can have a pretty serious fire on your hands.

The plane guys tend to have more attention to detail than car guys. They read instructions and learn to use products more throughly because planes can kill people and their personal liability can cost them big $$.

Car guys are a lot more lax in learning to use their stuff. Before you run LiPo's you have to educate yourself so you don't burn your new Lexus or home down to the ground.

I don;t think we will see LiPo's in TC for a while...
Car Manufacturers will have to design, test , redesign, test some more, cry a bunch and then test some more before a chassis design will even allow them to be run. How much added lead will have to be added just to make weight...LOL
With the advent of 3700 and 3800mah packs the runtime issue is almost mute.
Unless you are running a 4 turn and have it geared to space launching most 3800 packs can make 5 min.
Just my two pennies...
LiPo's will be great for 2wd buggies but for the rest of us....it will be a few more years till even a chassis is out there ready to use these cells.

I have used Lipos for a while now, but this in a model helicopter, 2 x 8000mah 30volts.

You have to treat the batteries with respect, as in the wrong hands and abuse they can be very dangerous and start a fire, they bulge and go bang. I have never seen this but I have heard of reports.

Because model car racing can be a rush, and model helicopter flying is more relaxed. At the current(No pun) time I think, normal SC cells are best for car racing.

Just my opinion

For a buck-twenty and change i think there should be something besides bullet connectors. Gold plated or not. A Tamiya style plug? Puh-leeze. I also agree on a built-in cut off to protect your investment. Am i the only one that is having serious throwback of Tamiya packs for the Frog and Falcon?? I actually dig the case... protected cells that dont overheat during use. Sweet.

The Tamiya plug is optional - many top racers use Team Orion or Corally connectors (they aren't plain steel bullet connectors!) and it's a clean look too. I don't think I'd want to be hardwiring Li-Po cells!

Yep...need to upgrade to a Li-Po charger, I can definitely see myself using these for a couple of heats, then charging up, then racing again...

Well I converted to the dark side of Lipo. I currently race at a track in Dallas setup for 1/8th scale Nitro but they allow us electric guys to race in our own heat too. There is a couple of guys there that run Lipo's in their XXX-4 and they are fast and they do not have to do the battery maintance I was doing. I purchased the Scorpion 6400 packs because on Saturday they run 15min mains.. YES 15 min mains in electric. Technology is changing and with us running brushless motors and better batteries I am ready to run 7min qual and 10 min mains. We were running 10 min mains with 3300 anyway.
