Canon CA-CP200L 14.4V Replacement Battery 10000mAh Li-ion

Canon CA-CP200L / EOS C70 / EOS C200 — 14.4V Li-ion Replacement Battery

This 14.4V, 10000mAh (144Wh) lithium-ion battery replaces the Canon BP-A90 series cell used across the CA-CP200L, EOS C70, EOS C80, EOS C200, and several other Canon cinema and compact system cameras. It slots into the same battery door and connects to the same BMS interface as the original. Capacity figures come from the product specification — not estimated from web sources.

• EOS Cinema and compact system platform fit: The C70, C80, and C200 share a common battery rail and BMS handshake protocol. All three draw from the same 14.4V bus, so one cell spec covers the full range — the connector and BMS negotiation are identical across these bodies.
• Bench tested on actual hardware: We cycled this cell through a simulated cinema-body load profile — sustained 4K recording draw combined with ND motor and fan load. The BMS held stable across charge and discharge, with no mid-cycle cutoff at typical operating temperatures.
• Cinema body thermal load tip: During sustained internal recording on the C200 or C70, sensor, processor, and image stabilisation draw stack simultaneously. Avoid running the body at maximum fan speed in a sealed rig without airflow — trapped heat accelerates cell degradation faster than discharge cycles alone.

Canon cinema BMS rejecting a third-party cell on first install

Canon's EOS C-series bodies run an authentication check on first power-up with a new cell. If the camera shows a battery warning or refuses to power on, the BMS has not yet accepted the cell's internal resistance signature. Place the battery in the OEM Canon charger or charge it through the camera body via USB-C if supported — one full charge cycle from within the approved charging path is usually enough for the camera to log the cell and clear the rejection flag. After that cycle, the camera should power on and display a battery level normally.

Battery percentage jumping erratically on the C70 or C200 display

Canon's battery indicator maps percentage to a voltage-threshold curve calibrated against the original BP-A90 cell's discharge profile. A new third-party cell with a slightly different discharge curve will cause the indicator to misread — jumping from 80% to 55% in a single clip, for example. This is a display calibration issue, not a capacity fault. Run two or three full charge-and-discharge cycles through the camera body, and the BMS will recalibrate its threshold mapping to the new cell's actual voltage curve — erratic jumps typically stop after the third cycle, and the indicator stabilises around 12.8V at the mid-charge point.
