Yongnuo YN-600 RGB LED Replacement Battery 7.4V 2600mAh

Yongnuo LED YN-600 RGB 3200-5500K CRI 95+ — 7.4V Li-ion Replacement Battery

This 7.4V 2600mAh (19.24Wh) lithium-ion cell replaces the battery used in the Yongnuo LED YN-600 RGB and a broad range of compatible Yongnuo LED panel models including the YN-216 and YN-300 AIR PRO series. It slots into the battery compartment at the rear of the panel and powers the RGB LED array, driver board, and control electronics. Voltage and capacity match the original specification.

• YN-600 RGB and YN-216 platform compatibility: These panels share a common NP-F style battery slot, 7.4V nominal voltage rail, and draw profile. The LED driver and colour-temperature control circuit both pull from the same cell, so voltage tolerance across the battery's discharge curve matters — this cell holds above the 6.8V cutoff that keeps the panel stable through a full colour temperature sweep from 3200K to 5500K.
• Bench tested on actual hardware: We ran this cell on the YN-600 RGB panel at full CRI 95+ output across both colour temperature extremes. The BMS held stable across the draw cycle, with no mid-session voltage collapse or thermal trip. Output stayed consistent from full charge down to the protection cutoff.
• First-use conditioning on LED panels: Yongnuo LED panels with a battery indicator display may show inaccurate charge percentage on the first cycle with a new cell. Run the battery from full charge to full depletion once — let the panel shut itself off naturally — then recharge completely. This calibrates the indicator to the new cell's discharge curve.

Why the YN-600 RGB dims or shifts colour at the low end of the charge cycle

The YN-600 RGB's LED driver is not fully regulated at all power levels. As cell voltage drops below roughly 7.0V during discharge, the driver board begins to lose headroom, and both brightness and colour accuracy can shift slightly — this is most visible at 3200K where the warm LED array draws more current. It is not a fault with the cell. Keeping a second charged battery on hand and swapping before the indicator reaches the final bar eliminates colour drift in critical shots.

Battery percentage jumping erratically on the YN panel display

Yongnuo's panel indicator maps battery percentage to fixed voltage thresholds tuned for the original cell's discharge curve. A replacement cell with a slightly different internal resistance will hit those thresholds at different points in its cycle, causing the display to jump — for example, skipping from 75% to 40% without warning. This is a display calibration issue, not a capacity fault. Run one full discharge cycle as described above and the display will settle to more consistent readings across subsequent charges.
