DAKEFPV BX 8S 70A 4-in-1 ESC

The DAKEFPV BX is a 4-in-1 electronic speed controller built for high-voltage, high-current power trains, accepting 3S to 8S LiPo input on a standard 30.5x30.5mm mounting pattern. It suits 7-inch to 10-inch long-range machines, heavy-payload cinelifters and X-Class builds that outgrow a typical 6S-rated ESC.

Key features

• 70A continuous current per channel with 75A peak headroom for large-stator cinematic and macro-quad motors.
• Wide 3S-8S input voltage range keeps current draw manageable on heavy, high-cell-count platforms.
• Onboard TVS protection plus a 35V 1000uF low-ESR capacitor suppress voltage spikes for stable power delivery.
• Compact 43 x 37 x 7mm footprint and 12g weight add minimal mass to the finished build.
• Rated to tolerate a wide range of temperature and humidity conditions for reliable field performance.

Pair it with a receiver and flight controller stack sharing the 30.5x30.5mm pattern; the wide input range makes this ESC usable across mixed fleets running different cell counts without swapping hardware.
