Blu Battery Voltage?

[VaporPhreak]

A buddy of min picked up a Blu about a year ago and vaped fro a good 3 months and gave it up and went back to smoking. He is about to give it another shot in order to get off the nasties, but I want to give him a hand with it. I know you can use 510 attys/cartos on blu batts, but does anyone know the actual voltage output of one of those batts? Is it a true 3.7(ish) or is more of a 3.1 like a stock 510 bat? Just curious as to how well a 510 atty/carto will work on it compared to a true 3.7(ish) battery.

I'm not sure of the voltage, but it (blu) is 90mAH vs a 510 which is somewhere around 180mAH-200mAH. 510 attys/cartos will work, but the blu battery life will be strained.
