HAKRC 4255 120A 12S Single ESC

The HAKRC 4255 is a single ESC built for heavy-lift, X-Class and high-voltage builds that need sustained high current beyond what a 4-in-1 ESC can handle.

Key features

• 120A continuous current with a 140A peak rating for large stators and oversized propellers.
• Runs on 6S to 12S LiPo power, well beyond standard 4-in-1 ESC voltage limits.
• 8-layer, 4oz copper PCB with a resin-plugged hole process and double-pad design for heat dissipation and overcurrent handling.
• Supports PWM, Oneshot125, Oneshot42, Multishot and DShot150/300/600 protocols.
• Ships with a thermal pad set, a heat sink set, a servo lead and a 10AWG main power lead for heavy-gauge soldering.

Specifications

• Continuous current: 120 A
• Peak current: 140 A
• Input voltage: 6S–12S LiPo
• Size: 55 x 28 mm
• Weight: 21 g
• Firmware: HAKRC-AT4G (AT32F421K8)

Suited to custom heavy-lift and cinelifter builds where standard 4-in-1 ESCs cannot survive the sustained amp draw of oversized motors.
