These are premium UBSC 18650 batteries
There’s no noticeable voltage sag even under heavy load - it easily powers my Acebeam M2, which according to my measurements draws around 9.4 A in Turbo mode. The cell stays stable and delivers full output without dipping or overheating, which is rare for a protected 18650.
It’s hard to find protected cells capable of this kind of performance. Acebeam clearly uses high‑grade cells and integrates solid protection circuits without sacrificing discharge capability.
