Direct replacement for Godox VB26B

This two-pack supplies 7.2 V lithium-ion cells rated at 3500 mAh and 25.2 Wh each. They match the original VB26B form factor for Godox V1, V850III and V860III series flashes as well as the AD100PRO speedlite. Photographers who need spare power for a full day of events will find the capacity a direct drop-in.

Simple swap with protected cells

Installation is a straight battery-door exchange — no tools, no firmware and no wiring. The packs include built-in circuits for over-charge, over-discharge, over-voltage, over-current and over-heating protection and meet UL 1642 and CE safety standards. The only common issue is forgetting to charge both units before a shoot, leaving one flat when the other is needed.

25.2 Wh per cell for extended bursts

Each battery delivers 25.2 Wh, giving noticeably more full-power flashes per charge than lower-capacity alternatives. They comfortably handle repeated bursts at wedding or portrait sessions. Runtime drops when the flash is fired at maximum output continuously or in very cold conditions, so a third pack is advisable for all-day high-intensity use.

Questions about this item

How can I confirm the Kastar VB26B batteries are working correctly after inserting them into my Godox V860III?

The flash should power on immediately and recycle at its normal speed; each pack delivers 7.2 V and 3500 mAh, so you will see consistent output for the full rated capacity.

What comes in the box and do I need to buy a charger separately?

The pack contains two VB26B lithium-ion batteries only; a compatible charger such as the Godox VC-26 or Flashpoint VC-26T is sold separately.

Which capacity should I choose between the 25.2 Wh VB26B and the VB26A?

The VB26B provides 3500 mAh and 25.2 Wh, while the VB26A is a lower-capacity variant; choose the VB26B for longer flash runtime.
