Overview
The Hobbywing EZRUN MAX4 HV is a high-voltage, waterproof brushless ESC for 1/5 scale RC cars and off-road trucks running 6–12S LiPo. It supports sensored or sensorless brushless motors, provides strong low-speed linearity in full-sensored mode, and includes an adjustable switch-mode BEC (6V / 7.4V / 8.4V).
Key Features
- IP67 waterproof system for all-weather track conditions (muddy, sandy, icy, snowy, and wet environments).
- Cont./peak current: 300A / 2000A.
- 6–12S LiPo input for high-voltage 1/5 setups.
- Switch-mode BEC output: 6V / 7.4V / 8.4V adjustable; 10A continuous; built-in BEC maximum output up to 25A.
- Capacitor thermal protection design.
- Built-in spark-proof circuit to help reduce arcing and connector damage when connecting high-voltage battery packs (6–12S).
- Advanced and secured electronic switch; longer life: 50000 times; waterproof/dustproof/shockproof design.
- Programming / upgrading / data reading wirelessly (with Hobbywing OTA module and smartphone with HOBBYWING HW LINK App installed).
- Real-time data & datalogging function; note: Bluetooth transmission distance is not effective within the 5m radius.
- New sensored cable interface; standard wire interfaces supported.
