FAQs:
Is the MB-390 compatible with all flashes that use the VB30 battery?
Yes. The MB-390 is designed as a direct replacement for the Godox VB30 and is tested for mechanical, electronic, and software compatibility with supported flash units. It fits and operates the same as the original battery, with no setup required.
Can the battery be charged without the original charger?
Yes. The built-in USB-C port allows the battery to charge from a USB-C mains adapter, power bank, or compatible charger. It supports Power Delivery charging up to 20W, reducing charging time compared to standard USB charging.
Does the higher capacity affect flash recycle speed?
The increased capacity itself extends shooting time, but the reinforced high-current cells also allow the battery to deliver strong output during rapid firing, helping maintain fast recycle times when shooting at high flash power or during continuous bursts.
How long can the battery sit unused without losing charge?
The MB-390 has very low self-discharge, with voltage dropping only slightly over time. This feature makes it suitable for photographers who keep spare batteries stored between jobs, as the battery will still hold a usable charge after long periods.
How long is the battery expected to last?
The battery is rated for roughly 700 full charge and discharge cycles thanks to its high-current cell chemistry. It also has no memory effect, so partial charging is safe and does not reduce lifespan, which is useful in everyday professional use.
