BetaFPV 2S Battery Charger and Tester

The BetaFPV 2S LiHV Battery Charger and Voltage Tester is an ultra-compact, dual-purpose power management tool explicitly engineered for Whoop and micro FPV drone pilots utilizing 2S high-voltage lithium cells, such as those found in the Aquila20 FPV Kit. Combining the capabilities of a dedicated field charger and a precise digital voltage diagnostic check block into a highly portable pocket-sized chassis, this device leverages a modern universal USB Type-C input architecture. Outfitted with an integrated clear LCD telemetry screen and native BT3.0 battery connector sockets, it offers seamless plug-and-play performance when powered by standard portable power banks, wall adapters, or electronic gear pipelines.

Features

Dual-Purpose 2-in-1 Architecture: Integrates two core utility pathways into a single micro-frame, serving as an automated fast-charging station and an instant diagnostic voltage checking terminal.

Universal USB-C Field Mobility: Powered via a standard USB Type-C input line, allowing pilots to reliably replenish flight packs anywhere by drawing power from portable power banks, vehicle ports, or laptop pipelines.

Dedicated Telemetry Feedback Display: Features a crisp internal LCD screen module that provides immediate visual readouts of real-time cell voltages and capacity progression states during charging loops.

Native BT3.0 Interface Integration: Engineered with specialized high-conductivity BT3.0 physical terminal sockets to ensure solid electrical transfer paths, minimized internal resistance drop-offs, and secure connection stability.

Micro-Sized Minimalist Engineering: Condenses comprehensive 2S LiHV battery maintenance functions into an incredibly small footprint, making it an ideal weight-saving accessory for tactical drone field packs and travel kits.

Operational Instructions

Input Power Interface Connection: Insert a high-quality USB Type-C cable into the device's input port and link the opposite side to a live 5V power supply or power bank. The LCD module will initialize to confirm standby readiness.

Voltage Verification Mode (Standby): To use the device strictly as a standalone telemetry tester, simply plug a 2S flight pack into the BT3.0 connector socket without attaching an external USB power input. The LCD will read out the current residual voltage of the pack.

Charging Cycle Execution: Connect the flight battery's BT3.0 lead firmly into the designated output socket after linking the charger to a live USB power source. The internal charge profile will deploy automatically, and the LCD will track the real-time voltage ascension.

Cycle Termination: Monitor the digital telemetry reading on the screen. Once the integrated cutoff safety software senses maximum capacity saturation at the high-voltage threshold, carefully disconnect the replenished 2S pack from the hardware grid.

Notes

Strict Chemistry Compatibility Constraints: This device is exclusively hard-wired and programmed to service 2S High-Voltage Lithium (LiHV) battery lines outfitted with native BT3.0 connectors. Never attempt to force normal-voltage 2S LiPo packs, 1S lines, or alternative battery chemistries into the port, as doing so will cause severe over-voltage cell destruction and presents an immediate fire hazard.

Continuous Supervision Policy: Never leave the charging hardware completely unattended during an active power loop. Always operate the station on a flat, solid, non-flammable, and well-insulated surface far away from carpets, wood, paper, or volatile materials. Protect the internal core from high-moisture exposure and severe mechanical shock.
