Product Tech Spec

STARTRC Charging Hub for DJI Mini Series Batteries

1. Universal Compatibility

  • Supported Models:
    Works seamlessly with DJI Mini 4 Pro, Mini 3, Mini 3 Pro, and their Intelligent Flight Batteries (e.g., 2453mAh, 3850mAh).
    • Charges all compatible batteries in one hub, eliminating the need for multiple chargers.
    • Note: Not compatible with older models like the DJI Mini 2 or Mavic Mini.
  • Smart Recognition:
    Automatically detects battery type and capacity, ensuring stable charging even at high altitudes.

2. Smart Storage Mode for Battery Health

  • 60% Storage Charge:
    Long-press the power button to activate Storage Mode, which charges batteries to 60%—ideal for long-term storage (e.g., seasonal use).
    • Prevents damage from over-discharging or overcharging.
    • Aligns with DJI’s recommendations for optimal battery lifespan.
  • Auto-Stop Function:
    Stops charging automatically at 60%, avoiding unnecessary energy waste.

3. Full-Charge Mode with Auto-Stop Protection

  • Optimized Full Charging:
    Charges batteries to 98–99% (not 100%) to extend battery lifespan, then cuts off power.
    • Indicated by a green light when near-fully charged.
    • Reduces strain on battery cells compared to traditional 100% charging.
  • Fast Charging Compatibility:
    Requires a DJI 30W USB-C or PD fast charger (not included) for maximum efficiency.

4. Rapid & Efficient Charging

  • Speed Performance:
    • 3× 2453mAh Batteries: ~135 minutes (~45 minutes per battery).
    • 3× 3850mAh Batteries: ~195 minutes (~65 minutes per battery).
    • Charges in descending order by battery level (highest first) to prioritize readiness.
  • Stable Output:
    Upgraded circuitry ensures consistent charging voltage, even in extreme conditions (e.g., high altitude).

5. Comprehensive Safety & Monitoring

  • 8-Layer Protection:
    Guards against over-current, over-voltage, over-temperature, short-circuit, over-charge, reverse polarity, electromagnetic interference, and over-discharge.
    • Built-in smart chip technology prevents damage to batteries and devices.
  • Real-Time LCD Display:
    Shows voltage, current, battery level, and charging temperature for each slot.
    • Prioritizes charging higher-capacity batteries first.
