GEPRC GEP-C1 Charger

The GEPRC GEP-C1 is a second-generation, high-performance dual-channel power management accessory engineered for micro FPV drone pilots utilizing 1S lithium power cells. Featuring a native USB Type-C input terminal, this highly portable station supports simultaneous dual-pack charging at a continuous 1.0A output per channel alongside an integrated multi-stage trickle charge protocol. The hardware configuration integrates custom GNB27 and PH2.0 connection interfaces, an on-board digital voltage telemetry display, and an audible buzzer alert system to deliver quick field diagnostics and safe battery cell conditioning without requiring complex bench equipment.

Features

Dual-Interface Terminal Grid: Each of the two independent charging lanes integrates physical GNB27 and PH2.0 hardware receptors, facilitating native plug-and-play maintenance without external adapter leads.

Isolated Dual-Channel Current: Supports concurrent charging of two independent 1S lithium packs at a steady 1.0A rate per channel, maximizing charging velocities via an optimized 2A total throughput ceiling.

Multi-Source Field Portability: Utilizes a native USB Type-C power input mainline that seamlessly pairs with external power banks, smartphone adapters, or laptop charging blocks for all-day field operation.

Automated Trickle Charge Protocol: Integrated smart software monitors real-time battery saturation curves, shifting automatically to a low-amperage trickle charge state near completion to ensure safe cell optimization.

Audible Status Telemetry: Equipped with an on-board acoustic buzzer that emits a clear three-tone audio notification sequence upon full charge completion, alerting pilots to swap packs safely.

Real-Time Power Indicator: Functions as a standalone voltage checking tool, immediately registering and displaying individual cell potentials down to decimal increments upon battery insertion.

Tri-Color Visual Matrix: Features independent LED diagnostic indicators that alternate through designated color states to reveal standby readiness, active current transfers, or finished cycles.

Solid Red (Active Charging Mode): High-amperage charging cycle currently in active progress.

Solid Green (Cycle Complete Mode): Recharging lifecycle finalized; target voltage cutoff achieved.

Operational Instructions

Interface the USB Type-C hardware power line with your chosen external power source to energize the board.

Connect a single 1S battery into the designated channel terminal receptor. The localized status LED will shift from green to solid red, and the LCD telemetry display will immediately showcase real-time voltage tracking to signify the start of the charging loop.

Upon full capacity cutoff resolution, the indicator light will transition back from red to green, and the integrated acoustic buzzer will emit a distinct three-tone notification sequence.

Safely disconnect the optimized battery pack from the hardware interface.

Notes

Hardware Constraint Policy: Each of the two charging zones houses one PH2.0 and one GNB27 port linked to a shared circuit. Never connect two batteries into the exact same numerical port channel simultaneously. Doing so will cause severe cross-cell discharge anomalies, structural battery expansion, permanent lifespan degradation, or localized thermal fire hazards.

Voltage Check Sequence: The digital screen provides real-time voltage monitoring immediately upon cell insertion. Use this feature frequently on the bench or in the field to check state-of-charge parameters before storing or flying packs.
