I used my multimeter and checked the voltage on the 905. It seems the voltage is regulated to 3.7 volts. The 14500 battery I am using was tested at 4.1 volts
The original voltage of the KR808D-1 is 4.0 volts
The voltage on my USB with battery passthrough is 4.0volts
The 510 batteries I tested fall between 3.7 and 4.0 volts.
One thing I noticed with higher voltage seems to be better flavor. Not necessarily higher vapor. But I think the taste is better.
The 905 v2 is used with a 901-510 connector and then a 510-901/808 connector. I was not able to use the cartomizer directly as the 905 does not have holes for airflow. Has anybody modded this by drilling holes??
