if you don't have a UBEC, then yes. though the voltage might be a tad too high.

I have tried this as a receiver pack before and it does work. It does tend to speed up the servo's though. Which may or may not be a good thing, depending on the setup.

These are 18650 cells. Most are rated at a max. amp drain of 5 amps, but that's the absolute max. They don't live very long when drained at 5 amps even.

The built in protection for a laptop battery, is in the form of a circuit board along side the cells in the pack. This protection is removed, unless you install the board with them. I'm sure that's it, on the end by the contacts.

I have used them to build flashlights, fans, and various battery powered thingies. If you want to put pcb protection on them, you can. But you have to purchase the pcb's for the voltage of the application. batteryspace.com has those in different Series setups.
