Wow, didn't realize how much they Jacked prices by house branding. $25.00 for a 650mah
I pay $7(ish)
Anyway, yes they are standard 510/ego connection batteries. They will attach to almost any 510 or Ego threaded device.
Basic - Ce5 or T2 - Top wick clearomizer
Upgrade - T3s, Evod, Vision Vivi Tanks
Performance/Durability - Protank/ Protank mini, Most Pyres/Glass Clearomizers
If/When the batteries Fail shop for more Main stream supplies. Variable Voltage for about the same price with higher Mah reserve.
For low maintenance, T2's and a few spare heads with medium ot light colored e-liquids will give longest vape time between servicing.
Every 5 to ? tanks, as performance falls, rinse and dry, swap wick head, fill and Vape.
Soak removed head in PGA(grain alcohol) Rinse and let dry.
I have T2's and original heads 1+yr old and still working, used in rotation.
