anyone ever try lithium ion cells?

i used to fiddle with 1/64 zipzaps and modify the hell out of those before i had my tmaxx. i know we did stuff like taking out the stock battery and stuffing a 3.7v li-ion battery in that would give crazy speed and like 45min of runtime. as opposed to a cheap 1.2v battery that when peak charged only lasted about 30-35min and was horribly slow. is this possible on a micro? i have a feeling the current drain could be too much for it though

Possible, but have a fire extinguisher on hand.

put the charger and batteries in a blast and fire proof glass case, with a smoke detector right above it, along with a speed-dial-under-fire button to your local fire department on the phone you will keep next to you at all times when charging li-ons. Then you'll have all the endless runtimes, lightweight and small power you shall ever need.

There was one case of a plane with a Li-ion battery (which wasn't connected by the way) that was sitting in a guy's car while he was flying his other plane. He turned around and saw his whole car engulfed in flames. Even if you charge it up without incident, that doesn't seem to guarentee safe usage afterward.

They can be dangerous....but.....to be devils advocate, Many of you out there with cell phones have LI-ion batteries inside. How many have caught on fire. I think the batts that catch on fire are most likely from improper charging or care (if a pack takes a serious jolt it may short internally). They are great cells for their size, just use extreme care, if they get banged up especially.

cell phone / laptop batteries dont explode because they have a safety circuit built in which limits discharge rate, and overvoltage protection when it is being charged.

I've seen lithiums pop when being used with extreme care, the technology is promising, but its still a couple years off from being safe for the majority to use.
