      Usage Notes

      • Please note the polarity markings on the device and do not connect the charger in reverse polarity.
      • The 2S Battery Charger and Voltage Tester only supports charging for 2S batteries, not 1S batteries.
      • The charger can only charge one battery at a time and is not designed for charging two or more batteries simultaneously.


      This charger is compatible with 2S LiPo batteries(8.4V) and has an XH2.54 battery port. Please note that charging 2S LiHV batteries (8.7V) may result in undercharging. We recommend using a LiPo 2S battery with a corresponding balance connector available in the market. During the charging process, if the digital display shows a voltage exceeding 8.4V (e.g. 9V), please disconnect the power supply immediately and check if there is any issue with the battery or the charger.

      2S Battery Charger and Voltage Tester


      This charger is designed to charge 2S LiHV batteries(8.7V) with a BT3.0 battery port. Please note that attempting to charge 2S LiPo batteries(8.4V) may pose a risk of overcharging. To ensure safe and optimal charging, we recommend using it with the BETAFPV BT3.0 450mAh 2S LiHV battery. During the charging process, if the digital display shows a voltage exceeding 8.7V (e.g. 9V), please disconnect the power supply immediately and check if there is any issue with the battery or the charger.
