Hello,
Great review, thanks. I buy one on BG.
Can you help me to understand why the turbo doesn’t work with protected 18650?
My S43 works fine except turbo mode with full charged protected battery Sanyo NCR18650BF. i double click to enter turbo mode , the light blink once and stop working. i have to unscrew the tail cap to reset the problem. With samsung INR 30Q the turbo mode works.
Is there a protection in the S43 that detect the battery can not supply enough power? but why to stop the light? it should works at lower level.

Sounds like the protection circuit on the battery is sensing the huge current draw and, thinking it’s a dead short, shutting down the output.

Yeah, that would be my guess too. The S43 on turbo draws a large amount of current. Around 10 amps or more? You really need an unprotected high-drain cell for proper performance.
