DJI Matrice 400 RTK – My Honest Review
Monday, June 23rd, 2025When DJI announces a new Matrice model, I get excited. I was genuinely looking forward to seeing what the new Matrice 400 RTK (M400) would bring to the table. Unfortunately, after digging through the specs, watching detailed breakdowns, and comparing it with the M350 RTK (which I’ve used and liked), I’m left disappointed.
Let’s break down what’s new, what’s good, and what’s not.
✅ What I Like
- Longer Flight Time: DJI claims up to 59 minutes with the H30T. Realistically, 40-45 minutes seems achievable in optimal conditions.
- Improved Obstacle Avoidance: Built-in Lidar and millimeter wave radar can detect 12mm wires at 38 km/h – no need for the CSM radar add-on.
- Better Video Transmission: The new O3 Enterprise system provides up to 25 miles (40 km) range.
- Higher Payload Capacity: Supports up to 13 lbs (6 kg) and up to 7 simultaneous payloads (e.g., speakers, spotlights, payload drop kits).
- Cruise Mode + AR Map: AR overlays and automated waypoint navigation for hands-off inspections.
- Tethered Power Support: First DJI platform to support the TB100C tethered station for extended hovering.
- Manifold 3 Support: AI compute onboard for advanced mission workflows.
❌ What I Dislike
- Single Battery Design: M400 uses a top-mounted TB100 battery. It supports online swap (<45s), but I prefer dual TB65s for redundancy.
- Top Battery Mount: Like the old Mavic series. I’ve seen top batteries fall mid-flight due to swelling or poor alignment.
- No Backward Payload Compatibility: Legacy payloads like XT2, Z30, and H20 aren’t supported. That’s a big problem for existing M300/M350 owners.
- Charging Workflow Downgrade: BS100 can only charge one TB100 at a time. That’s slower than BS60’s dual TB65 charging.
- RC Plus 2 Limitation: While I do like the RC Plus 2, it doesn’t support the DJI Mavic 3 Series. That’s frustrating for mixed drone teams.

---|---|---|
Flight Time (Max) | ~55 mins (claimed), ~32-34 real | Up to 59 mins (H30T), ~40-45 real |
Battery System | Dual TB65 batteries | Single TB100 battery |
Battery Redundancy | ✅ Yes (dual) | ❌ No (single) |
Online Battery Swap | ✅ Yes | ✅ Yes (~45s window) |
Battery Mounting | Side-mounted | Top-mounted |
Charger | BS60 (8 TB65 + 2 WB37) | BS100 (3 TB100 + 2 WB37, 1-at-a-time) |
Payload Support | ✅ XT2, Z30, H20, L1 | ❌ Not compatible with older payloads |
Max Payload Capacity | ~6 lbs (2.7 kg) | 13 lbs (6 kg) |
Obstacle Avoidance | Visual + optional CSM radar | Visual + Lidar + mmWave Radar |
Remote Controller | RC Plus 2 | RC Plus 2 |
Dual Operator Support | ✅ Yes | ✅ Yes |

💰 Price (US Estimate)
- Matrice 350 RTK: $11,500-$13,000 depending on payload/bundle.
- Matrice 400 RTK: $14,900-$16,000+ depending on configuration. TB100 battery and BS100 charger sold separately.
🧊 Final Thoughts
The M400 brings serious upgrades in certain areas, especially in obstacle sensing, payload support, and range. But if you’re already using the M300 or M350, there’s not enough to justify a switch especially if you’ve invested in older payloads and ground gear.
🟦 Recommendation: Stick with the M350 RTK unless you specifically need the M400’s longer range, AI compute, or radar capabilities.
I’m sticking with the M350.
