DJI PowerPro WB37: Long-Lasting Universal Battery

The DJI WB37 is the extended-runtime battery for DJI's enterprise smart controllers — the original RC Plus (used with M30T, M350 RTK, M300 RTK) and the RC Plus 2 Enterprise Enhanced (used with the M4 Series). Slots into the controller's external battery bay and roughly doubles the controller's runtime for extended-mission operations.

Quick Facts

• Compatible with: DJI RC Plus (M30T, M350 RTK, M300 RTK) and DJI RC Plus 2 Enterprise Enhanced (M4T, M4TD, M4E)
• Function: Extended controller runtime via external battery slot
• Capacity: Verify current DJI specifications for mAh and Wh rating
• Charging: Charges through the DJI BS30 / BS65 charging stations (built-in WB37 slots) or standard DJI charger
• Delivery: 5 to 7 business days

What This Battery Does

DJI's enterprise smart controllers have an internal battery for baseline operation and an external battery bay for a WB37 extension. With just the internal battery, the controller runs for the duration of one mission. With a WB37 also installed, runtime is roughly doubled.

For extended SAR operations, multi-hour incident command shifts, full-day inspection runs, or fleet operations where you don't want to stop and charge the controller mid-mission, the WB37 is what keeps the controller running across the operational day.

The WB37 is the unified extended-battery solution across DJI's RC Plus and RC Plus 2 enterprise controller line. If you run a mixed fleet (M30T plus M4 series, for example), you can use the same WB37 inventory across all of those controllers — one of the operational advantages of the unified battery design.

How to Charge the WB37

The DJI BS30 Intelligent Battery Charging Station (included with M30T kits) and the DJI BS65 Charging Station (used with M350 RTK kits) both have dedicated WB37 charging slots in addition to the flight battery slots. You can charge controller batteries simultaneously with your flight batteries from the same charging station.

WB37s can also be charged through DJI's standard charger with the appropriate adapter for operators without a station-based charger.

Who Buys This Battery

• M30T, M4 Series, and M350 RTK operators running extended-shift operations who need more than the internal controller battery provides
• Public safety agencies running multi-hour incident command sessions where the controller can't stop and recharge
• SAR teams on extended missions where downtime to charge a controller is operationally unacceptable
• Pipeline and infrastructure inspection contractors running full-day inspection runs from a single controller
• Mixed-fleet operators who want a single battery type that works across multiple aircraft platforms
• Operators replacing an aged WB37 with reduced runtime from extensive cycle use
• Anyone with a backup controller who wants a spare WB37 for redundancy

Frequently Asked Questions

Does the WB37 fit my RC Plus 2 controller for the M4 series?

Yes. The WB37 is compatible with both the original RC Plus (used with M30T, M350, M300) and the RC Plus 2 Enterprise Enhanced (used with M4T, M4TD, M4E). DJI kept the battery form factor consistent across the controller generations, so a single WB37 inventory works across mixed fleets.

How long does the WB37 extend my controller runtime?

The WB37 roughly doubles the controller's operational runtime when paired with the internal battery. Real-world runtime depends on screen brightness, transmission link load, and ambient temperature. Verify current DJI specifications for exact runtime numbers.

How do I charge the WB37?

If you have a DJI BS30 charging station (typically included with M30T kits) or a BS65 (with M350 RTK kits), both have dedicated WB37 charging slots — you can charge controller batteries simultaneously with flight batteries from the same unit. WB37s can also be charged through the standard DJI charger with the appropriate adapter.

How many WB37 batteries should I keep on hand?

For most single-pilot operations, one WB37 per controller is sufficient. For dual-pilot or extended-mission operations, two WB37s lets you swap out the spent one mid-mission without stopping. For agencies running fleet operations, plan one WB37 per controller in the active duty rotation.

Can I use one WB37 across multiple aircraft platforms?

Yes, as long as you're using the corresponding controller. If you have an M30T (RC Plus) and an M4T (RC Plus 2), the WB37 fits both controllers. This is one of the advantages of DJI standardizing the controller battery across the enterprise line.

Is the WB37 covered by warranty?

Batteries are consumable items and not covered by DJI Enterprise Care or CPS Drone Protection plans. If your battery arrives defective, contact us within 72 hours of delivery and we'll coordinate a replacement under our DOA policy. After that window, normal battery degradation through cycle use isn't covered.
