Holybro's current official listing identifies this Mini 50A version as 4S, while some older/third-party listings describe it as 4–6S. For a design or product datasheet, I would use the current manufacturer's specification (4S) unless you can identify the exact hardware revision.
Key Feature:
- All new High-quality MOSFETs with low internal resistance & heat generation, and individual metal heatsink
- New and faster F4 MCU @ 150Mhz (compared to F3 @108Mhz & F0 @48Mhz)
