DJI Mini 4 Pro / Mini 3 Series Two‑Way Charging Hub + 2× Flight Batteries

Compatible Products

• DJI Mini 4 Pro*

• DJI Mini 3 Pro

• DJI Mini 3

In The Box

• 1 × DJI Mini 4 Pro / Mini 3 Series Two‑Way Charging Hub

• 2 × Intelligent Flight Battery

(USB‑C cable / charger NOT included — use DJI 30 W or USB‑PD source.)

Product Overview

The hub holds 3 batteries sequentially — charging the highest‑charged cell first for fastest relaunch — and doubles as a 5 V/2 A power bank to top up your phone or RC in the field. Each 2453 mAh Li‑ion 2S cell delivers 34 min (Mini 3 Pro) / 38 min (Mini 3) flight at 21.6 km/h, keeping total airborne time at ~72 min per outing with 2 spares. With a DJI 30 W USB‑C PD charger, 3 standard cells fully charge in ~3 h (≈58 min/hub slot). The <249 g class keeps you registration‑free in most regions — note: using Mini 3 batteries in Mini 4 Pro reduces performance & pushes weight >249 g.

Key Features

Sequential 3‑Slot Charging — Highest First

• 3 Independent Bays: Auto‑detects charge level — fullest cell charges first.

• PD Input: 5 V/3 A, 9 V/3 A, 12 V/3 A — optimized for DJI 30 W / any USB‑PD brick.

• Full Cycle Times (@30 W):

• 3× Standard IFB: ~3 h (≈58 min per cell in hub)

• 3× IFB Plus: ~4 h (≈78 min per cell in hub)

• Single‑Cell (Hub): Standard IFB ≈56 min / IFB Plus ≈78 min.

Two‑Way Power Bank Mode

• USB‑A Output: Max 5 V/2 A — discharge batteries to charge phone / RC / Osmo.

• Lowest‑First Discharge: Hub auto‑selects the least‑charged cell to preserve fullest packs for flight.

• Field Utility: No wall outlet? Use stored battery energy to keep mobile devices alive on location.

LED Status & Storage

• Per‑Slot 4‑LED Arrays: Show charge progress (cycling) or full (solid/off).

• Integrated Transport: Hub secures up to 3 cells — no loose batteries in bag; protects contacts for airline carry‑on.

• Compact Footprint: Lightweight shell, fold‑flat profile for sling / backpack.

️ Intelligent Flight Battery (BWX162‑2453‑7.38) — 18.1 Wh

• Capacity: 2453 mAh / 18.1 Wh (Li‑ion 2S, 7.38 V nom / 8.5 V limit).

• Weight: 80.5 g per cell — keeps drone <249 g with standard battery.

• Flight Time:

• Mini 3 Pro: up to 34 min (21.6 km/h constant)

• Mini 3: up to 38 min (21.6 km/h constant)

• Mini 4 Pro with this cell: reduced thrust & <31 min; weight >249 g

• Max Charge Power: 37 W (cell) / 30 W via hub or aircraft.

• Smart BMS: Voltage/temp monitoring, auto‑storage discharge to 72 % after 9 days.

Usage Tips

• 30 W PD Recommended: DJI 30 W or certified USB‑PD (≥30 W) — lower wattage bricks extend charge time significantly.

• Insert All 3 (drone‑mounted + 2 spares): Hub auto‑sequences — fullest cell ready first for fastest relaunch.

• Power‑Bank Wake: Unplug wall charger, connect device to USB‑A — lowest‑charge cell discharges first.

• Mini 4 Pro Warning: Using these Mini 3 batteries in Mini 4 Pro → thrust reduction + >249 g → check local regs (EU C1 → A2/A3).

• Storage Care: Batteries auto‑discharge to 72 % after 9 days idle — store hub with cells inserted for managed care.

• Airline Safe: 18.1 Wh × 2 = well under 100 Wh — carry‑on approved (terminal caps advised).

️ Important Notes

• Mini 3 Battery in Mini 4 Pro: ️ Reduced propulsion & flight time; takeoff weight exceeds 249 g — re‑classification required in most jurisdictions.

• No Cable/Charger Included: Hub ships without USB‑C cord or 30 W brick — reuse drone cable or supply PD adapter.

• USB‑A Output Only: Power‑bank port is legacy USB‑A — no USB‑C output on hub.
