About this replacement
Canon ES-8000V / FV500 Series — 7.4V Li-ion Replacement Battery (BP-950)
This is a 7.4V, 4400mAh Li-ion replacement for the Canon BP-950 and BP-950G battery. It fits a wide range of Canon camcorders including the ES-8000V, V50Hi, FV500, and ES-7000es. The cell chemistry and connector match the original spec to work with the camcorder's onboard BMS.
- ES-8000V / FV500 platform fit: These camcorders share the same 7.4V two-cell Li-ion rail and the same BP-950 connector. The BMS on each body reads cell voltage and temperature data through the same pin arrangement, so one battery type serves the full group.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Canon camcorder body. The BMS accepted the battery without fault codes, and the protection circuit triggered correctly at the low-voltage cutoff threshold.
- First charge on Canon camcorder bodies: Insert the battery and charge it from within the camera body or Canon OEM charger before your first recording session. Some Canon camcorders require one full internal charge cycle before the battery-remaining indicator maps correctly to the new cell's discharge curve.
Canon BMS rejecting a third-party cell on first install
Canon camcorder bodies run an authentication check when a new battery is inserted. A third-party cell can trigger a "change the battery pack" warning or show no charge indicator on the very first install, even when the cell is fully charged. This is not a defective battery — it is the BMS waiting to complete its first handshake. Charge the battery fully using a Canon OEM charger or inside the camcorder body, then reinsert and power on.
Battery percentage jumping erratically during recording
Canon camcorders map voltage thresholds to display segments calibrated against the original cell's discharge curve. A replacement cell with a slightly different discharge profile causes the indicator to jump — for example, dropping from three bars to one bar quickly, then stabilising. The battery capacity itself is not at fault. Run one full charge-to-cutoff cycle inside the camcorder body and the BMS will recalibrate its threshold mapping to the new cell.
