BetaFPV BT2.0 Battery Charger and Voltage Tester V2

The BetaFPV BT2.0 Battery Charger and Voltage Tester V2 is an upgraded, dual-purpose maintenance accessory engineered for pilots utilizing micro FPV 1S battery systems equipped with BT2.0 connectors. This revised iteration integrates a standardized USB Type-C input terminal, removing the constraints of older proprietary charging lines and allowing power draw from standard wall adapters, power banks, or PC ports. The hardware configuration features simultaneous dual-pack charging at a continuous 1.0A output per channel alongside an integrated digital voltage telemetry display. When disconnected from an external power supply, the secondary output port functions as a standalone digital voltage checker for instant field diagnostics.

Features

Streamlined Structural Geometry: Features a refined aesthetic overhaul incorporating a low-profile, high-contrast white LCD screen and concealed status LEDs under a semi-translucent protective casing.

Dual-Channel Charging Engine: Supports concurrent charging of two independent 1S lithium packs at a steady 1.0A rate, fully replenishing a 300mAh cell in approximately 20 minutes and a 450mAh cell in 30 minutes.

Type-C Hardware Power Interface: Updated from older connection standards to a native USB Type-C receptacle, providing seamless integration with modern charging ecosystems and field power supplies.

Isolated Voltage Telemetry Routing: When the Type-C input is completely unpowered, the designated OUT1 hardware terminal routes the battery's active cell potential directly to the LCD screen, converting the unit into a highly precise field voltage checker.

Dual-Color Visual Diagnostics: Localized independent LED matrices provide immediate charging status updates, shifting between clear operational states to indicate ongoing energy transfers or full capacity cutoffs.

Operational State Matrix

Type-C Connected (Power In): Dual-charging ports are fully energized. The LCD screen illuminates to show active states, and both channel paths deliver a regulated 1.0A current. Dedicated red and green LEDs control tracking for each pack.

Type-C Disconnected (Power Out): The charging circuitry is completely deactivated. Connecting a 1S cell into the specialized OUT1 port automatically powers on the LCD screen using the battery's residual energy, immediately displaying the exact real-time voltage of the pack down to two decimal places.

Notes

Channel Parameter Separation: Do not attempt to force standard PH2.0 battery terminals into the native BT2.0 ports. Always ensure your micro lithium cells utilize matching BT2.0 factory caps to guarantee proper electrical conductivity and prevent reverse-polarity shorts.

Storage Voltage Monitoring: Use the unpowered OUT1 tester mode frequently during field sessions to ensure your packs do not discharge beneath the critical threshold of 3.0V per cell under static conditions, which can lead to rapid chemistry failure.
