The Torchy battery, if OK with that 'roughing up' is a good enough battery. I suspect it has two wraps. vaping it at 55 watts isn't going to last long. It won't be 'empty' but eventually the mod will say no.
I use those on a 2 x 18650 mod (Fuchai or Smoant) by the way. Twice as many batteries at half the power.... so mine last days not hours.
You could consider an inbuilt battery mod but beware because usb ports do break/mess up... and then you can't charge it. Actually, my smartphone usb is also now broken... which means new smartphone. Darn it.
I would consider ordering some wraps for those unless they are really old anyway.
PS Last year I was saying how great it was to be able to charge via usb at my holiday home. Now that home has my old charger as my beaten up mods all need me to take the batteries out because of failed usbs. Grim...
