Yongnuo YN-600 RGB Compatible Battery 7.4V 2000mAh

Yongnuo LED YN-600 RGB / YN-216 / YN-300 AIR PRO Series — 7.4V Li-ion Replacement Battery

This 7.4V 2000mAh (14.8Wh) Li-ion cell replaces the battery used in the Yongnuo LED YN-600 RGB 3200-5500K CRI 95+, YN-216, YN-300 AIR PRO, and 27+ additional Yongnuo LED panel models. It slots into the same battery bay and connects to the panel's onboard BMS through the same contact arrangement as the original cell. Voltage and physical dimensions match the OEM specification exactly.

• YN-600 RGB, YN-216, and YN-300 AIR PRO compatibility: These panels share a common 7.4V two-cell Li-ion battery platform with the same connector footprint and BMS communication protocol. A single replacement cell works across the range because the protection circuit interface and contact pinout are identical across the lineup.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the YN-600 RGB platform. The BMS accepted the cell without error, and the protection circuit triggered cleanly at the low-voltage cutoff threshold — no false trips during sustained high-output operation at full RGB saturation.
• First-cycle conditioning on variable-colour panels: The YN-600 RGB draws uneven current across its colour channels when mixing warm and cool LEDs simultaneously. Run one complete charge cycle at that mixed output before a critical shoot — this lets the BMS map the cell's discharge curve accurately under the panel's actual variable-draw pattern.

Colour output shifting on the YN-600 RGB as the battery drains

The YN-600 RGB manages warm and cool LED channels through separate current drivers, both fed from the same 7.4V cell. As cell voltage sags under load, the two drivers can lose regulation at slightly different thresholds, causing the mixed colour temperature to drift before the panel shuts off. This is not a fault with the replacement cell — it is a voltage-sensitivity characteristic of the panel's driver circuit. Keeping cell voltage above 7.0V during critical colour-matched shots avoids the drift window entirely.

Panel powers on but output brightness drops sharply within seconds

This happens when the BMS reads an initial voltage that satisfies the power-on threshold but the cell has not been fully charged before use. The YN-600 RGB's driver circuit pulls a sustained high current at full output, and if the cell is below roughly 7.2V at rest, the BMS trips the overcurrent protection within the first draw cycle. The fix is straightforward: charge the replacement cell to full before first use in the panel. If the drop still occurs after a full charge, verify the charger output is hitting 8.4V at termination.
