Replacement Battery for Godox Flash Units

The Kastar VB26B is a lithium-ion power pack built to replace the original Godox VB26B cell used in V1 round-head flashes, V850III and V860III speedlights and the AD100Pro speedlite. It also fits Flashpoint Zoom Li-on X, X Pro and III series units. Photographers who need a spare or replacement for these specific flash systems can use this single-pack battery.

Capacity Limits of a Single 7.2 V Cell

At 3500 mAh and 25.2 Wh the cell stores a fixed amount of energy that determines how many full-power flashes are possible before recharge. The built-in protection circuit stops charging or discharging if voltage, current or temperature exceed safe thresholds, so the practical limit is the cell’s rated capacity rather than any external controller. Users cannot exceed this energy budget without swapping to a fresh battery.

Runtime Headroom for Event and Portrait Work

A fully charged VB26B comfortably powers a Godox V1 or V860III through a typical portrait session or half-day event with normal recycle intervals. High-speed continuous firing or frequent full-power dumps will deplete the 25.2 Wh reserve faster, requiring a spare pack or recharge via the compatible VC-26 charger. The single-pack format means no redundancy unless a second unit is carried.
