The Lumenier 25A 4 in 1 BLHeli_S ESC features the powerful
BusyBee2 (EFM8BB21F16) chip that runs at at 48MHz 2x the speed of
prevoius BLHeli_S ESCs. This BB2 processor allows the ESC to perform
with incredible precision (up to 500kv eRPM support), resulting in
smooth and responsive power and taking full advantage of the BLHeli_S
firmware. This 4 in 1 ESC is mini is size with a 20x20mm mounting holes,
and it is low profile and compact in size, saving weight and making
builds easy. These ESCs are OPTO (no BEC) and come with motor, signal
and power wires for your convenience. The set also includes plastic
standoffs and plastic screws with nuts for mounting the ESC. The ESC
features new BLHeli_S firmware pre-installed on them. They are
compatible with PWM, Oneshot125, Oneshot42, and Multishot protocols.
Simply enable the feature in the flight controller software and the ESC
will automatically match it. This ESC also supports DSHOT protocol.
These BLHeli_S ESCs feature hardware PWM controllers running at
36KHz, which is more than double of previous software PWM ESCs at 16KHz.
This results in ultra smooth throttle response and near silent motor
This tiny 4-in-1 ESC is perfect for mini 3" and 4" brushless quads, and even ultra-light 5" low amp draw racing builds.
With all ESC's that have active braking we recommend you isolate
or filter all sensitive electronics to prevent feedback / spikes.
