The E20 PRO is an ultra-lightweight (1.2g) RDT and timer solution, featuring both DT and brushed 60A motor outputs with an exceptionally low internal resistance of only 0.006 ohms.
Designed with large direct-soldering pads for battery input and output, it ensures high-current capacity and robust, low-resistance connections for peak performance.
It features an integrated onboard radio receiver, fully compatible with BMK RDT Transmitters. Each transmitter uses a unique security code and can be bound to an unlimited number of BMK receivers.
