Kastar VB26B 3500mAh Li-Ion battery

This Kastar VB26B is a 7.2V lithium-ion camera battery rated at 3500mAh and 25.2Wh. It serves as a direct replacement for Godox VB26, VB26A and VB26B packs used in round-head flashes such as the V1 series and AD100PRO. Photographers who need reliable spare power for on-location shoots will find it matches the original form factor and voltage.

Sustained flash recycling performance

The high-capacity cell delivers longer run time between charges than lower-rated alternatives, letting a compatible flash maintain consistent recycle speeds throughout a session. Built-in protection circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating, so the pack sustains output without tripping or degrading prematurely under repeated full-power pops.

Thermal behaviour and charging safety

Cells meet UL1642 and CE safety standards, limiting temperature rise during intensive burst shooting. The pack charges on Godox VC-26 or Flashpoint VC-26T chargers without excessive heat buildup, and the internal protection shuts down current flow if temperatures exceed safe limits. This keeps the flash unit cool and the battery stable during typical event or portrait workflows.
