does anyone know all the different flashes and what they mean?

sounds to me that battery flashing when you are not doing anything could be the cleaning cycle, especially because you get a good hit right afterwards. The cleaning cycle heats up very hot, you can read more about it on other threads.

It has no charge, it flashes when I put it in the charger

Not sure Zed, my m401 and m201 flash 5 times when I connect it to the charger, then the light turns from green to red. You mean no charge as in not activating the atomizer, or no charge when checked with a voltmeter?
