Ezviz DP1S Replacement Battery 3.85V 6800mAh Li-Polymer

Up to 20% off
New arrival
From $41.99 USD $51.99
Shipping calculated at checkout.
Fits Ezviz DP1S wireless security camera; replaces OEM part MLP416281P directly.
3.85V, 6800mAh Li-Polymer cell delivers sustained power for motion detection and night vision IR without voltage sag during high-draw events.
Connector seats into the camera's bottom battery slot with single-tab lock; orientation marked on the housing to prevent insertion errors.
We bench-tested this cell in the DP1S platform — BMS accepted the new pack on first contact cycle, no fault lockout observed during sustained IR operation.
On first install, power cycle the camera once through the app so firmware registers the new cell before motion recording logs correctly to cloud storage.

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.

Ezviz DP1S — 3.85V Li-Polymer Replacement Battery (MLP416281P)

This is a 3.85V, 6800mAh Li-Polymer battery for the Ezviz DP1S wireless indoor security camera. It replaces OEM part MLP416281P and fits the camera's original battery bay without modification. Use it when the original cell no longer holds charge and the camera begins dropping offline or failing to complete motion-triggered recordings.

  • DP1S platform fit: The DP1S uses a flat Li-Polymer cell at 3.85V nominal — a voltage rail tied directly to the camera's SoC and IR LED array. The MLP416281P form factor is specific to this chassis; the BMS must match the camera's charge management circuit to prevent false low-battery flags in the Ezviz app.
  • Bench tested on actual hardware: We cycled this cell through the DP1S charge circuit and verified the BMS correctly reported state of charge to the camera firmware. The cell held stable voltage under the combined IR LED and processor load during simulated motion-trigger events.
  • First-install power cycle: After fitting the battery, power cycle the camera once through the Ezviz app. The firmware must register the new cell before motion event logs record correctly to cloud storage — skipping this step can cause the clip counter to stay at zero despite the camera detecting movement.

DP1S going offline in the Ezviz app after a battery swap

Swapping the battery clears the camera's active session token. The DP1S does not automatically re-authenticate to the Ezviz cloud after power is restored from a cold battery install. The camera appears online on the local network but the app shows it as unreachable or offline. Open the Ezviz app, go to device settings, and trigger a manual reconnect — the camera will re-register and resume live view within 60 seconds.

App reporting 0% or wrong battery percentage after fitting a new cell

The DP1S uses a voltage-threshold indicator, not a fuel gauge IC, to estimate battery level. When a new cell is installed, the firmware's stored discharge curve doesn't match the fresh cell's resting voltage, causing it to misread state of charge — often showing 0% or a low percentage immediately after install. Run the camera through one full charge cycle to 4.35V and allow it to draw down under normal use. After one complete cycle, the threshold map resets and the app percentage tracks correctly.

Frequently Asked Questions

The DP1S stops recording mid-clip — the video cuts off before the motion event ends. What's causing this?

A WiFi reconnect during recording pulls a current spike that can trip the BMS on a weak or intermittent signal — the camera interprets this as an overload and cuts the recording to protect the cell. Check the camera's signal strength in the Ezviz app; anything below two bars is enough to cause this. Move the camera closer to the router or add a WiFi extender. Once signal is stable, the BMS won't see the reconnect surge and recordings complete in full.

Motion detection stops working overnight but the camera is still online in the app — what's happening?

The IR LED array draws sustained current during night vision mode, and if the cell voltage dips under load, the BMS can throttle power to non-essential functions — motion triggering is first to drop. This is more common with an aged original battery but can also appear on a new cell that hasn't been calibrated with a full charge cycle. Charge the replacement to 100% before the first overnight run. If motion dropout continues, check the Ezviz app sensitivity settings — they reset to default on some firmware versions after a battery swap.

The Ezviz app shows the DP1S battery jumping between charge percentages erratically — is the battery faulty?

Erratic percentage readings on the DP1S are almost always a firmware calibration issue, not a faulty cell. The camera's voltage-threshold system estimates charge by comparing resting cell voltage to fixed reference points — if those points were set against an older, degraded cell, a fresh 6800mAh cell will read inconsistently. Run one full charge-to-discharge cycle without interruption. After the cycle completes and the camera returns to full charge, the threshold references reset and the percentage stabilises.
