MEGA SPEED High Speed Video Compatible Battery 14.8V 10400mAh

MEGA Speed High Speed Video Camera — 14.8V Li-ion Replacement Battery

This 14.8V, 10400mAh (153.92Wh) Li-ion battery replaces the original power pack for the MEGA Speed High Speed Video Camera. High-speed video capture puts sustained load on the cell — this replacement is rated to handle that draw without voltage sag killing a recording session mid-clip. Dimensions are 151.00 × 95.80 × 56.90 mm; confirm these against your current pack before ordering.

• High-speed capture platforms: High-frame-rate recording pulls significantly more current than standard video — the sensor, image processor, and buffer are all active at once. This cell's 10400mAh capacity at 14.8V provides the headroom these platforms need to sustain burst capture without the BMS tripping on a momentary load spike.
• Bench tested on actual hardware: We cycled this cell under sustained high-draw loads and monitored BMS behaviour at both full charge and low-voltage thresholds. The protection circuit held cutoff at the expected floor without nuisance trips during peak current draw.
• First-install charge cycle: Run one full charge cycle through the OEM charger before heavy shooting. Some camera BMS systems require an internal charge cycle to calibrate the battery-remaining display — skipping this step can cause the indicator to read inaccurately from the first use.

Why the camera kills power mid-clip during high-frame-rate recording

At high frame rates, the sensor readout, image buffer, and storage controller all draw current simultaneously. If the cell voltage sags below the BMS cutoff threshold during this peak load, the camera shuts down to protect the circuit — even if the battery indicator showed charge remaining. A degraded original cell will sag earlier and harder than a fresh replacement. Swapping to a new cell with full-rated capacity restores the voltage floor that keeps the system stable under burst load.

Battery percentage jumping or stuck immediately after fitting the replacement

This happens because the camera's BMS maps voltage thresholds to percentage readouts using data from its previous cell — the discharge curve of a new cell doesn't match those stored reference points exactly. The indicator can read 100%, then drop sharply, or stall at a fixed number for an extended period. Perform one full charge-discharge cycle through the OEM charger to allow the BMS to remap its thresholds against the new cell's curve. After that cycle, percentage readings should track normally across the full discharge range.
