Two-Pack Li-Ion Replacement for GODOX V1 Flash

The Kastar VB26B pack supplies two 7.2 V lithium-ion cells rated at 3500 mAh and 25.2 Wh each. They replace the original VB26, VB26A and VB26B packs used in GODOX V1 series round-head flashes and compatible Flashpoint Zoom Li-on units. Photographers who need spare power for long shoots can carry both cells without changing charger or flash.

Built-In Protection Circuits Limit Heat

Each cell integrates over-charge, over-discharge, over-voltage, over-current and over-heating safeguards that meet UL 1642 and CE requirements. The protection logic keeps temperature rise modest during repeated full-power flashes and prevents damage if a cell is left on the charger or discharged deeply. Normal use stays within the design envelope without extra cooling.

Direct Fit for GODOX VC-26

The batteries slot into the original VC-26 and Flashpoint Zoom VC-26T chargers, so no new charging hardware is required. Compatibility extends to V850III, V860III and AD100PRO speedlights as well as the full V1C, V1F, V1N, V1O, V1P and V1S flash range. Users who rely on other flash systems or need higher capacity than 3500 mAh will not be served by this pack.

Questions about this item

How do I install the VB26B batteries into my GODOX V1 flash, and what step do people often miss?

Slide each battery into the flash compartment until the latch clicks; the step many miss is confirming the 7.2 V label faces outward so the contacts align with the flash terminals.

What maintenance or replacement will the VB26B pack need later?

Expect gradual capacity fade after several hundred charge cycles; replace both cells together when a full charge no longer powers the flash for a typical session.

What limit appears first during sustained full-power flashes with the VB26B?

The built-in over-heating protection circuit will pause output before the 25.2 Wh capacity is fully drained, letting the cells cool before firing resumes.
