About this replacement
Canon ES-8000V / FV500 Series — 7.4V Li-ion Replacement Battery (BP-970)
This is a 7.4V, 6600mAh Li-ion replacement for Canon's BP-970 battery pack. It fits the ES-8000V, V50Hi, FV500, ES-7000es, and over 90 additional Canon camcorder and camera bodies that share the same BP-970 footprint and connector. Swap it in when the original cell no longer holds a usable charge.
- BP-970 platform compatibility: Canon built a wide range of camcorders and cameras around the same 7.4V dual-cell Li-ion rail, unified connector, and BMS handshake. Every body on the fit list draws from the same voltage spec, which is why one cell covers such a broad model range.
- Bench tested on actual hardware: We cycled this cell through a Canon camcorder body and monitored BMS communication. The protection circuit handled charge termination correctly and flagged cell status accurately on the body's display throughout the test cycle.
- First-use charge cycle for accurate indicator readings: On first install, run a full charge from within the Canon OEM charger or camera body before any recording session. Some Canon BMS implementations need one complete charge cycle to calibrate the remaining-battery display to the new cell's discharge curve.
Canon BMS rejecting a third-party BP-970 cell on first install
Some Canon bodies — particularly older ES and FV series — run an authentication check when a new cell is seated. If the body shows a blinking battery icon or powers off immediately, it has not yet accepted the cell's BMS handshake. Remove the battery, reinsert it firmly, then place it in the OEM charger for a full charge before returning it to the body. One complete charge-in-charger cycle is usually enough to clear the rejection state and allow normal operation.
Battery percentage jumping erratically during recording
This happens when the camera body's indicator is still mapping voltage thresholds from the old cell's worn discharge curve onto a new, full-capacity cell. The replacement discharges at a shallower slope than a degraded original, so the body misreads the mid-range voltage band and skips percentage steps. Run two full charge-discharge cycles through the body to let the BMS re-map thresholds against the new curve. After conditioning, the display should track steadily from 100% down to the low-voltage cutoff at approximately 6.0V.
