What's inside x200 battery?

[mt12345]

The battery in my x200 holds just 10 minutes.

I have six Samsung 18650 3.7V rechargeable batteries lying in the drawer and I was wondering if it was possible to replace the cells in x200's battery. Anyone looked inside?

It's absolutely possible, but you have to be careful to keep battery controller powered on. If you just disconnect cells from it, if will block itself and it's tricky to return it back to life.

Are you saying the cells inside x200 battery and 18650s are the same size?
There should be reset button on the controller I guess?

There isn't one.
