Four-pack Li-ion replacement for Godox flash units

This four-pack supplies 7.2 V 3500 mAh 25.2 Wh lithium-ion cells that fit Godox V850III, V860III series and AD100PRO speedlights as well as compatible Flashpoint Zoom models. Each cell carries built-in protection against over-charge, over-discharge, over-voltage, over-current and over-heating. The pack is designed for photographers who need reliable spare power for extended shoots.

Replaces Godox VB26, VB26A.

Swapping to this pack is worthwhile when original batteries no longer hold a full charge or when a session demands more cycles than a single cell can deliver. The integrated safety circuits meet UL 1642 and CE standards, reducing the risk of unexpected shutdowns. Users who already own a Godox VC-26 or Flashpoint VC-26T charger can continue using it without change.

Delivers 25.2 Wh per cell for longer flash sequences

At 3500 mAh each battery comfortably powers multiple full-power pops and recycling intervals during events or portrait sessions. Capacity drops off when continuous high-drain bursts exceed the cell's thermal limits, so very rapid-fire shooting may require rotation between spares. The four-pack format provides enough headroom for a full day of typical on-camera flash work.

Questions about this item

What battery compartment size fits the 4 × 3 × 2 inch VB26B pack?

The pack measures four by three by two inches, matching the GODOX VB26B slot used in V850III, V860III and AD100PRO flashes.

How do I install the VB26B and what step is often missed?

Slide each 7.2 V 3500 mAh cell into the flash until the latch clicks, then charge fully on a VC-26 charger before first use — skipping that initial charge is the common error.

When will the VB26B need replacement and how do I tell?

After several hundred cycles the 25.2 Wh capacity drops noticeably; replace the pack when flash recycle time lengthens or the charger shows a full charge that drains quickly.
