Default Lithium Poly Batteries - The future of R/C!

Anyone get the new Xtreme RC Cars magazine? Well in it they have an article about Lithium Poly 8000mah batteries, they're definetly going to be the future of R/C. They did a head to head test with the lithium poly cells against GP3300's, here are the results...

Quote:
Li-Po weight: 287g
GP3300 weight: 366g

Li-Po run time: 20 minutes
GP3300 run time: 6 minutes

Li-Po acceleration (0-60 feet):1.67 seconds @ 39.8mph
GP3300 acceleration (0-60 feet): 1.82 seconds @ 32.8mph

Li-Po top speed: 47.2
GP3300 top speed: 41.2
What does everyone think?

FROM WHAT I HAVE HEARD IN HK SOME RACES HAVE 8 MIN MAINS.

WON'T 20 MIN TAKE TOO LONG? YOU MIGHT BURNOUT YOUR MOTORS.

I THINK YOU WOULD NEED ANOTHER CHARGER FOR THAT. I DONT THINK STANDARD CHARGERS WOULD WORK.

IT WOULD BE NICE TO HAVE LONGER RUN TIMES/RACES.

They really shouldn't cost anymore than a quality pack of matched 1.17's. The batteries they used were designed for laptops and cell phones.

That's correct, a charger specifically for NiMH or Nicad's won't work, however the article did say that the Great Planes Triton charger will infact work with these batteries. (http://www.towerhobbies.com/products.../gpmm3150.html)

Keep in mind, this article was just about the future of R/C, do not expect to see these batteries in stores for at least a few more years. By the time these batteries are released to the R/C masses, i'm sure there will be new motor and car technology or something.

I also should mention, the article stated 20-30 minute runtime, it was just the statistics part that said 20 minutes.

They also tested with a Hacker brushless system. They did mention that a standard brushed motor probably can not handle the abuse of Lithium Poly batteries. They seemed impressive...I would like to see it in person though. I know those batteries will not fit very well in my Xray. The cars will have to change as well...also you can't dump the Lithium cells as they can not handle a very low voltage...you'll destroy the cell structure.
