Mobile phone lipo cells...

[tymill]

Like many people, I've accumulated quite a few Sony Ericsson phone batteries like these.

They weigh close to nothing, but are rated at 950mAh.

Surely two could just be wired up in series and run in a car for a super-lightweight, hard-cased battery setup...

I six were used (three sets in parallel) that'd be a decent 2850mAh battery that weighs close to nothing and is more or less free.

Would there be big issues with regards to the current draw and/or overheating? (I'd be surprised if there would not be!) After all mobiles are designed to run for hours, where they'd be sucked dry in a matter of 2-3 minutes in an rc application.

Very curious...

Maybe they'd be great in mini-rc applications?

Any thoughts are appreciated!
