>>22725634Yeah. I'm finding a lipo battery which could fit in the section.
But the only thing holding me back is that due to being so cheap, this doesn't have any low voltage protection. The battery should cut off at 3.2 volts but the headlamp died at 2.4 volts. Even if I put in a premium battery there is no circuitry to keep it in health state.
I'll just buy another. The brightness is between 150 and 300 Lumens compared to my fenix light
Although I did the replacement in another flashlight. Replaced their fake battery with a genuine 18650. Runtime increased from 1 hour to 8-10 hours.
