1. Either or is ok. 2. Either or is ok. :welcome:Awaiting delivery of my X45 and would like to purchase a spare set of (4) 18650's for it. I'm not sure what type to get, button top? Flat top? Protected or unprotected? I need help!
You're welcome. I use flat top unprotected in my X45, and button top VTC6 in my GT94, and in other lights where they are required, due to mechanical reverse polarity protection. The X45 does not have mechanical reverse polarity protection, so either or is ok.I ended up getting a set of button top VTC6. Thanks.
