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.

XH2.54

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.

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.

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:

• BT3.0 Connectors

BT2.0 Connector

BETAFPV exclusive designed BT2.0 connector has broken through the bottle-neck
of PH2.0 connector. BT2.0 connector decreased internal resistance of connector effectively to allow more current that is transferred, which means it supports 9A continuous current(15A burst) offers stronger power and longer flight time on 1S brushless drones while PH2.0 just supports 4.5A You can enjoy more flight time without disturb of low voltage warning through solving the problem of voltage sag. For more instruction, click here to reach.

There is a graph of comparison between BT2.0 connector and PH2.0 connector
(solid pins version) in BETAFPV 1S 300mAh battery. The discharge current
is 9A in this testing. You could see that it has double time (about
2minutes) with BT2.0 connector.

Much more choices of BT2.0 series accessories. We know some of the pilots
might have a question about how to deal with the old PH2.0 1S battery.
So we provide some accessories like BT2.0 Power whoop connectors for
those people who wanna convert the PH2.0 connector to a BT2.0 connector.
