New arrival
From $37.99 USD $46.99
Shipping calculated at checkout.
Fits DJI Osmo Mobile 2, Mobile 3, Mobile 4, and Osmo Mobile 3 SE; replaces OEM part 2ICR18650-2S1P.
Delivers 7.4V at 2600mAh capacity; sustains the three-axis gimbal motor load across full stabilization cycles.
Connector seats into the battery slot with a spring-loaded contact pair; locking tab engages flush with housing.
Bench testing showed the BMS accepted voltage handshake within 90 seconds of first insertion; no fault codes on load.
On first use, charge fully in the DJI charging dock before mounting to the gimbal — the firmware needs a complete BMS cycle to register remaining capacity on the display.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,
Michael

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

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.

Frequently Asked Questions

My Osmo Mobile 2 shows a low battery warning immediately after fitting the new cell, even though it just came off the charger — what's happening?

The gimbal's BMS bases its state-of-charge reading on resting voltage, and a new cell's resting voltage after its first charge can sit outside the curve the firmware expects. Power the gimbal off, leave it for 10 minutes to let the cell voltage settle, then power back on. If the warning clears, run one full discharge and recharge cycle — that resets the BMS reference point and the indicator reads correctly from that point forward.

The Osmo Mobile 3 gimbal arm feels sluggish and drift-correction is slow after fitting the replacement battery — is the cell causing this?

Axis response speed depends partly on how much current the motors can draw without the BMS throttling output. If the replacement cell's contacts aren't fully clean and seated, contact resistance creates a voltage drop that the BMS interprets as a weak cell and limits motor current accordingly. Clean the gold contact pads on both the cell and the gimbal body with a dry cloth, reseat the battery, and run the motor calibration step in the Mimo app. Motor response should return to normal after calibration with a fully charged cell reading above 7.2V at rest.

The Osmo Mobile 4 drains much faster in cold weather with the new cell compared to the original — is that normal?

Li-ion cells lose available capacity in cold — typically 15–25% below 10°C — because lithium-ion mobility through the electrolyte slows with temperature. That's a chemistry limitation, not a cell defect. Keep the gimbal in an inside pocket between shots to hold the cell closer to ambient body temperature. Once the cell warms above 15°C, capacity and stabilization performance return to the rated level.
