Since the bottom of the CH is exposed, it won't work with the chi-you clone. At least not the kind I have. The button housing is all metal. Better to use AW IMR, Sony 30 amp, Samsung 20r, r the Panasonic NCR18650PF or PD. Do not use protected batteries. Rtdvapor.com has the AW and Panasonic batteries. Illuminationsupply.com has the Sony , Samsung, and Panasonic batteries. Again, say no to protected batteries. Only high drain IMR or IMR hybrids.
