PatrolEyes SC-DV5 Replacement Battery 3.7V 1250mAh Li-Polymer

PatrolEyes SC-DV5 / SC-DV5-2 — 3.7V Li-Polymer Replacement Battery (SC-DV5-RB)

This is a 3.7V, 1250mAh (4.63Wh) lithium-polymer replacement battery for the PatrolEyes SC-DV5 and SC-DV5-2 body cameras. It physically fits the same slot as the original SC-DV5-RB cell and connects to the same BMS circuit. Capacity and voltage match the factory spec exactly.

• SC-DV5 and SC-DV5-2 compatibility: Both models use the same battery bay dimensions and the same 3.7V single-cell BMS handshake. The connector orientation and cell footprint — 52 x 34 x 10.60mm — are identical across both variants, so one replacement covers both units.
• Bench tested on actual hardware: We cycled this cell through the SC-DV5 BMS at full charge and discharge. The protection circuit responded correctly to end-of-charge cutoff and low-voltage cutoff without tripping false flags or locking the camera out of record mode.
• First-install charge cycle on the SC-DV5: Run the first full charge inside the camera body using the OEM cable before heavy field use. The SC-DV5 BMS maps the battery-remaining indicator to the discharge curve during this first cycle — skipping it causes the indicator to read inaccurately from the start.

Why the SC-DV5 locks to standby mode before the battery reads empty

The SC-DV5 uses a voltage-threshold system to protect the LiPo cell from deep discharge. When the cell drops below roughly 3.4V under load, the camera exits record mode and forces standby even though the indicator may still show one bar. This is the BMS cutoff working as intended, not a fault with the replacement cell. A fresh charge cycle resets the threshold, and the camera returns to normal operation immediately after recharging.

Battery percentage jumping erratically on the SC-DV5 display

This happens when the camera's internal indicator table is calibrated to the original cell's discharge curve and the new cell discharges along a slightly different voltage slope. The display reads voltage and maps it to a percentage — if the mapping table doesn't match the new cell, the readout skips between values. Run two or three full charge-discharge cycles through the camera body to let the BMS recalibrate. After conditioning, the indicator should track steadily down from 4.2V at full charge.
