Yay....Nothing like having to buy more new batteries, brushless motors, etc, etc. Yuck. If this trend continues I may have to race buy some nitro powered cars

Default Brushless is so easy

Maintenance free. No comms or brushes to tweak or maintain. You will never go back.

I like maintaining my motors. Thats why I refuse to buy brushless stuff.

But back to the batteries.

What is the best type of charger to use with the Li-poly's? I'm in the market for a charger that'll do li-poly's and nihm.

The Astro Flight 109 D is one of the best LiPo charges at around $129. It seems to be sold out all the time, but I know one places that keeps lots of stock of this charger:

the 109 will not do nimh, for the price the Triton is the best lipo charger that will also do nimh, nicd, and even Pb.

i have a Triton and it works great!

I agree about brushless! I'd buy one in a heartbeat and sell my lathe if they opened up a touring class for those motors. It's just one less thing to worry about and more power too!

Default Triton a great all-around charger.

Charges anything. Temperature probe option for additional safety.

I can see people missing brushed motors if they love to tinker and feel their ability to tune a brushed motor gives them an advantage. Me....I'd rather be turning a corner with the car than turning a comm.

The only disadvantage of Li/Polys is the cost. You'll get less charge cycles out of a battery that costs two or three times as much. Having said that, they don't cost that much more than matched packs, and like brushless motors less hassle to maintain (just get a good charger.) The loss in weight is a nice plus too.

Less charge cycles?

I thought NIMH had around 50 good charge cycles while LiPo had over 300

i don't have lipoly's yet, but I love the brushless thing. I had to run a 19 turn today in my sedan because not enough people showed up for brushless... man it sucks when you haven't spent the time getting a motor ready. Lipoy's don't really charge slow... they just have over double the capacity of the GP's. The other cool thing about brushless and lipoly. long run times with loads of power. It even beats out nitro in speed, power and run time.

I have run 2-cell Li-Po packs. They make the best sub-C packs you can get fell like crap. A 6000 Mah Li-Po is about the same wieght as a 3000 NiMH 4-cell.

Default 50 cycles from NiMH!!!!

I've never heard numbers that low quoted for NiMH. The numbers I've heard quoted are 800 cycles for NiCd. 600 cycles for NiMh and 300 cycles for Li/Ion. I think those are ideal numbers based on gentle use and good maintenance. RC's are tough on rechargeables. I usually kill nicads before I get 800 cycles from them...similarly, I've killed quite a few NiMh's...many by not taking care of them well in the off season. Li/Ion is more robust to sitting around because they have much lower self drain rates.
