Thanks for your replies, gents.
d_t_a, you’re right as to my reason for wanting protected 14500s. As an amateur I guess I’m just a little leery of unprotected lithium ion cells and want to be extra careful. And good idea to list my 1xAA lights. Here they are (to date):
Lumintop Tool 2.0
Convoy T2 (new version)
Thrunite T10 II
Sooner or later, I’m likely to add a Manker E05.
I also have a Fenix E12 V.2.0 and an L3 Illumination L10C and a couple of L11Cs, but none of these are suitable for 14500s.
zoulas, I’m interested in your recommendation of Sofirn 14500s as I’m a fan of Sofirn. But the only Sofirn 14500s I’m aware of are these: https://www.sofirnlight.com/4pcs-14500-batteries-900mah-p0032.html I emailed Sofirn about them a while back and they told me that they are unprotected. Can you point me to the protected Sofirn 14500s you’re referencing?
