30A DYS brushless controller

Input voltage: 7.4V to 16.8V DC (2 - 4S Li - xx) BEC: 5V 2 amps
Output: 30A (output: 30A continuous 40 A max up to 10 sec.)
Size: 36mm (L) x 26mm (l) x 7mm (H).
Weight: 32g.
Programmable Items:

1 Brake Setting: Enabled / Disabled, default is Disabled

2. Battery Type: Li-xx(Li-ion or Li-poly) / nor-xx(NiMH or NiCd), default is Li - xx.

3 Low Voltage Protection (cut-off Mode) Mode: Soft cut-off (Gradually reduce the output power) Cut-Off gold (Immediately stop the output power). Default is Soft Cut-Off.                                                           

4 Low Voltage Protection Threshold (cut-off Threshold): Low / Medium / High, default is Medium.

(1) for lithium batteries, the number of battery cells is calculated automatically. Low / medium / high cutoff voltage for each cell is: 2.6V/2.85V/3.1V. For example: For a 3 cells lithium pack, when ° Medium¡± cutoff threshold is set, the cutoff voltage will be: 2.85 * 3 = 8.55V.

(2) for nickel batteries, low / medium / high cutoff voltages are 0% / 45% / 60% of the startup voltage (i.e. the initial voltage of battery pack), and 0% means the low voltage cut-off function is disabled. For example: For a 10 cells NiMH battery, fully charged voltage is 1.44 * 6 = 8.64V, ° Medium¡± when cut-off threshold is set, the cutoff voltage will be:8.64*50%=4.3V

5 Startup Mode: Normal underbody Super-Soft, default is Normal.

Normal is preferred for fixed-wing aircraft. Soft Gold Super-soft are preferred for helicopters. The initial acceleration of the Soft and Super-Soft modes are slower in comparison, usually taking 1 second for Soft startup or 2 seconds for Super-Soft startup from initial throttle advance to full throttle. If the throttle is closed (throttle stick moved to bottom) and opened again (throttle stick moved to top) within 3 seconds of the initial startup, the restart-up will be temporarily changed to normal mode to get rid of the chances of a crash caused by slow throttle response. This special design is very suitable for aerobatic flight when quick throttle response is needed.

6. timing: Low / Medium / High, default is Low.

Usually, low timing value can be used for most motors. We recommend the Low timing value for 2 poles motor and Medium timing value for motors with more than 6 pole to get a high efficiency. For higher speed, High timing value can be chosen.
