Your torch is dying mid-shift and the disposable AA pack is a money pit. This Jaycar 14500 Li-Ion cell gives you 800mAh at 3.7V on a nipple terminal — the size most compact LED torches were designed around. One charge, one long walk, no swapping batteries in the dark.
One thing before you plug it in: this is an unprotected cell. No built-in BMS. If your device or charger expects a protected cell, stop. Read the manual. Mismatching the two is genuinely dangerous. The right charger and the right housing make this a reliable daily driver.
