This chargeris designed to charge 2S LiHV batteries(8.7V)with a BT3.0 battery port. Please note that attempting to charge 2SLiPobatteries(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.
The BETAFPV BT3.0 series accessories represent a line of products tailored exclusively for 2S whoop drones, comprising three categories of items, connectors, battery, and charger, forming an integrated set of accessories capable of working in perfect harmony. The BT3.0 connectors obviate the need for balance connectors while streamlining the BT3.0 450mAh 2S Battery (2PCS) and enabling greater convenience and higher performance of the 2S drones. When used in conjunction with the 2S Battery Charger and Voltage Tester, a more efficient and stable charging experience can be realized.
We highly recommend combining the following products to upgrade your 2S whoop drone with a set of efficient and user-friendly accessories:
