Replacement battery for Xiaomi 2S series

This Cameron Sino BM20 battery replaces the original cell in Xiaomi 2S, M2, MI2 and MI2s handsets. It uses a 2050mAh lithium-ion pack rated at 7.59Wh. Integrated protection circuits guard against overcharging and short circuits. The unit is sold new and ready to restore daily runtime.

Sustained daily performance

High-quality cells deliver consistent voltage across a full discharge cycle rather than only in short bursts. Protection circuitry maintains safe limits during continuous use such as navigation or video playback. Stable output prevents unexpected shutdowns when the charge runs low. The pack meets OEM specifications for reliable everyday operation.

Straightforward installation

Precision engineering ensures the battery seats correctly in the phone chassis without forcing connectors. No soldering or specialised tools are required beyond a standard opening pick. The main risk is damaging the fragile ribbon cable if the back cover is pried too aggressively. Builders who need a higher-capacity pack will not find that option here.
