The BLSMAX 30A is a high-efficiency ESC with optimised BLHeli firmware, sold with a Deans connector. The page describes a design for brushless DC motors with compact, lightweight construction, a smooth start-up, fast throttle response and reliable motor control.
It offers 30A continuous and 40A burst current, a low-resistance design for power efficiency, a built-in 5V/2A BEC and multiple protection features. The page says it suits drones, RC planes and multirotors and does not list a cell range. It showed 17 units at Rs 609 (SKU TIFQC0203).
30A continuous, 40A burst: as listed.
BLHeli firmware: smooth and responsive control.
Low-resistance design: for better power efficiency.
Built-in BEC (5V/2A): for stable output.
Deans connector: named in the title.
Multiple protections: for safe operation.
An electronic speed controller (ESC) converts the throttle signal from the flight controller into the three-phase power that a brushless motor needs. It switches battery current through MOSFETs at high speed, so the motor turns at the speed that the pilot or autopilot asks for. The continuous current rating shows how much current the ESC can carry all the time, and the burst rating shows what it can survive for a few seconds.
Match the ESC to the rest of the power system. The battery cell count must fall inside the listed range, the continuous current must be higher than what your motor and propeller draw at full throttle, and the signal protocol (for example PWM, Oneshot, Multishot or DShot) must be supported by your flight controller. An ESC marked OPTO has no built-in BEC, so the receiver and flight controller need power from another source. An ESC with a BEC can supply a regulated voltage, usually 5V, to small electronics.
Install and test carefully. Solder joints must be clean and strong, the motor wires should be kept short and tidy, and the ESC needs airflow because current makes heat. Calibrate the throttle range if the ESC needs it, check the motor direction with the propellers removed, and never connect a battery with the propellers fitted while you are working on the wiring. Use a battery with a cell count and connector that suit the ESC, and check for a heat problem after a short test hover.
