About this replacement
DJI Osmo Mobile 2 / Mobile 3 / Mobile 4 — 7.4V Li-ion Replacement Battery (2ICR18650-2S1P)
This 7.4V 2600mAh Li-ion cell replaces the OEM battery in the DJI Osmo Mobile 2, Mobile 3, and Mobile 4 smartphone gimbals. It powers the three-axis motorized stabilization system that keeps footage smooth during handheld recording. Capacity figures come from our product data — 2600mAh / 19.24Wh.
- Osmo Mobile 2, 3, and 4 compatibility: These three gimbal generations share the same internal battery form factor, connector orientation, and voltage rail. The BMS in each model reads cell voltage directly — no encrypted authentication handshake — so a correctly rated replacement cell initializes without rejection.
- Bench tested on actual hardware: We cycled this cell through the Osmo Mobile 2 charge circuit and monitored BMS cutoff thresholds at both ends. The protection board tripped at the correct low-voltage floor and accepted charge termination without overrun.
- Gimbal motor calibration after cell swap: After fitting a new cell, run the DJI Mimo app's motor calibration routine before your first recording session. A fresh cell at slightly different resting voltage can cause the gimbal to report axis drift if calibration data from the old cell is still stored in firmware.
Why the Osmo Mobile cuts stabilization mid-session on a new battery
The Osmo Mobile's three motor axes each draw current simultaneously during aggressive stabilization moves. On a cell with any internal resistance above spec — common in degraded originals — the combined motor surge pulls voltage low enough to trigger the BMS undervoltage cutoff. A new cell with lower internal resistance handles the surge without tripping. If cutouts still happen after fitting a replacement, check that the cell contacts are fully seated — even 0.1mm of contact gap adds enough resistance to mimic a weak cell under load.
Battery percentage stuck at 1% or jumping erratically on the DJI Mimo app
The Mimo app maps battery percentage against a discharge curve calibrated to the original cell. A new cell with a slightly different discharge curve causes the indicator to read incorrectly — most visibly at the top and bottom 15% of charge. Run two full charge-discharge cycles through the gimbal to let the BMS re-map its state-of-charge model against the new cell's actual curve. After two cycles, the percentage display stabilizes. If it stays erratic, confirm firmware is current — DJI has pushed BMS curve updates in several Osmo Mobile firmware revisions.
