Replacement battery for DJI Smart Controller

This 5000mAh 7.4V lithium pack replaces the WB4-5000 cell inside the RM500 Smart Controller. It matches the original voltage and capacity so the controller runs for the same duration. Safety circuits guard against over-charge, over-discharge, over-voltage and short circuits. The pack measures 66.7 x 37.0 x 20.0mm and weighs 179.0g.

Who should buy this and who should not

Pilots who need a fresh power source for the RM500 Smart Controller will find the correct fit and connector here. Buyers who want more storage, a different voltage or a pack for another controller model should look elsewhere. The battery is certified to ISO9001, RoHS, CE, UN38.3 and MSDS for regulated transport. It is sold as a single unit.

Capacity and voltage that decide compatibility

The decisive figures are 5000mAh capacity and 7.4V nominal voltage; the controller only accepts a pack with those exact ratings. A 5200mAh / 38.48Wh label on the cell confirms the same energy envelope. If your device requires a different capacity or voltage this battery will not work.
