on Vapage hybrid BF 2.0 and poor ultrafilre brc 3000mah:XL - unloaded - 3.82 volts
- loaded - 3.41 volts
SB - unloaded - 3.82
- loaded - 3.70
It appears there is a fair amount of additional resistance in the mod itself....thus requiring the need for the lower 1.5 attys.
3,91v/3,46V
4,01v/3,66V
I'll check tomorrow for better batteries
as you like (I have at hand leads) to connect directly to the battery atty and then measure - this will give the final answer
