BetaFPV 2S Batterieladegerät und Tester - JST-XH

The compact and simple charger and voltage meter from BetaFPV is designed for 2S LiPo batteries. It is equipped with a standard JST-XH connector for connecting the battery’s balance lead. Once a battery is connected, charging starts automatically, requiring no further setup. The charger is intended for standard LiPo batteries with a final voltage of 8.4V. In addition to charging, it also works as a tester, displaying total battery voltage and individual cell voltages on its screen, which also indicates the charging status.

The device supports the PD3.0 fast-charging protocol and uses a USB-C connector as input, allowing compatibility with a wide range of modern chargers and power banks. The input voltage range is 5–12V (max 2.5A), with a maximum output power of 15W.

Charging status is indicated by a red LED: solid red means charging is in progress, off indicates charging is complete, and flashing red signals a battery error. The charger is designed exclusively for 2S batteries and can charge only one battery at a time.
