@red5
I followed your advice mate and used a new mollicell p42 21700 battery to test it. The display showed 4.2 volts to start and when i fired it it rose to a maximum of 4.9 volts. This was with a 0.70 ohm coil at 35 watts.
On my jellybox and aspire mods, the voltage rose to 5.25 volts and the hit was much more instant.
I agree with your findings about it feeling very underpowered, and that is with a brand new fully charged battery) I do think that it will work better with different builds ,and maybe someone else will find it better suited for their own style of vaping.
I will be closing this sale as it doesn't feel right to charge someone if they have the same results as me.
With that said
@StrawberryRipple and
@Crispycritters I would like to post one each out to you both free of charge, and hope that it suits you both better than me. If you would like one, just Pm me your address and I will get them sent out on Monday as I am working all weekend.
Thank you all for the good advice
Cheers
