SkyRC e680 8A/80W universal charger with power supply

The SkyRC e680 is a highly versatile, single-channel universal AC/DC smart balance charger and power supply station engineered to deliver comprehensive battery management for a wide matrix of hobby, industrial, and consumer cells. Positioned as an advanced, feature-rich upgrade to the classic e660 model, this unit features an integrated AC power transformer alongside wide-range DC input capability. Tailored to meet the needs of modern RC pilots, it incorporates dedicated charging profiles for High-Voltage Lithium (LiHV) chemistry and specialized DJI Mavic smart batteries, alongside deep diagnostic capabilities such as internal resistance analysis, cold-weather lead-acid cell reconditioning, and a regulated 13.8V DC power output loop.

Features

Integrated Dual-Input AC/DC Topography: Outfitted with a built-in 80W AC power transformer for clean bench deployment directly from wall outlets, while natively supporting an 11V to 18V DC input rail for field usage.

Specialized DJI Mavic Integration: Incorporates dedicated firmware sub-routines tailored to service smart DJI Mavic flight batteries at a continuous current up to 4.0A, replenishing intelligent packs faster than standard stock alternatives.

Regulated DC Power Supply Mode: Bypasses standard balancing loops to transform the device into a stable, 13.8V DC power source, reliably driving low-voltage bench gear like LED pit lights or field equipment built for 12V automotive accessory rails.

Advanced Lead-Acid "Cold-Charge" Reconditioning: Features an optimized winterization routine specifically designed to safely warm, condition, and efficiently recharge frozen or heavily chilled Lead-Acid (Pb) utility batteries in low ambient temperatures.

Internal Resistance Cell Diagnostics: Onboard processor tracking measures individual lithium cell internal resistance steps, providing real-time evaluation of pack state-of-health, capacity stability, and matched cell performance.

High-Conductivity Banana Port Outputs: Features heavy-duty, standard 4mm bullet/banana physical terminal sockets, facilitating stable electrical transfers, minimized resistance paths, and universal lead compatibility.

Operational Instructions

Interface Setup: Connect the heavy-duty AC power line to a wall outlet or bridge the DC input terminals to a stable field battery. Power on the charger module to illuminate the text-based 1602 LCD terminal.

Battery Orientation: Hook up the flight battery pack to the primary 4mm banana output terminal sockets, observing strict color-coded polarity. Concurrently plug the white multi-pin JST-XH lead into the dedicated side balance port block.

Configuration Profile Selection: Navigate the scOS system menus to set the battery chemistry, matching cell count, target cutoff threshold, and appropriate current limits.

Execution & Disconnection: Initialize the charge cycle. The 1602 text display will showcase real-time telemetry variables. Once capacity target triggers terminate the pipeline, promptly disconnect the battery from the output grid.

Notes

Balance Lead Mandatory Policy: When charging any multi-cell lithium pack (2S through 6S), you must connect both the primary high-current lead via the 4mm banana adapter and the corresponding JST-XH balance board socket simultaneously. Attempting to charge multi-cell series lines without individual channel balance telemetry bypasses critical safety overrides and can cause severe cell over-voltage, localized battery expansion, or thermal hazards.

Proper Chemistry Selection Target: Always verify that the selected chemistry profile on the digital menu strictly matches the physical battery type connected. Charging a standard 4.20V LiPo pack under the elevated 4.35V LiHV profile will cause immediate cell degradation and poses a severe fire hazard.

Storage Safety Practices: Store the system completely powered down and disconnected from batteries in an isolated environment away from direct exposure to moisture, excessive heat sources, volatile materials, or explosive vapors. The recommended ambient thermal window for long-term standby storage is -10°C to +30°C.
