Shopgirl a HV atty on a USB Passthru wont work very well , most are designed for 6-7 volts so a 2 battery device ( 2 x 3.0 v , or 2 x 3.7v ) is where the become beneficial IMO .
Of course this is not cut and dry !! a little experimenting is in order
Benefit of a HV atty is the it makes the High Voltage devices more usable , they would POP a regular atty very easily , these HV ones have a higher resistance ( that lowers the power ) and stress on the atty.
Hope this helps ?
