Turnigy 5A SBEC is an advanced switching DC-DC regulator which will supply a constant 5A. It works with 2 - 7 Cell Lipoly pack and supplies a constant 5 or 6v to your receiver and is interference-free.
hi all, i have an old speed controller (turnigy multistar 20amp) and it has a sbec in it(5.5v 4A). could i use this as a bec to power only my reciever in a nitro car. i can solder off the motor wires. the reciever im using is the hk-gt2. i am running 2 servos. help would be greatly appreciated.
I can't be sure but from everything I've read it does not look like it has a low voltage cutoff if you are using this with an electric motor then your electronic speed control will have a low voltage cutoff that will let you know your battery is getting low if you're using this with a glider then I would also order A low voltage alarm please read the reviews as this bec might not be the one for you.
Nah I'm not using it with a ESC as such... I have it to power my arduino, sensors and servos on my robot. Using a homemade L298 driver board to control the motors. I was thinking another way to make a cutoff would to be to connect the 1st cell of my 2s lipo to a analog input of my arduino and then read it that way. Is there any reason I must monitor all cells? Or just the 1st untill it falls below the threshold. Also I could probally monitor both cells with some resistors but that would use an extra pin.
Hello ArduinoFlyer, first of all, Thank you. Once again I caution you this is a 5amp maximum ESC and it has quite a bit of voltage drop off at least this is what it says in the reviews. That being said you will always want to monitor all of the cells in any LiPo battery if the second sale drops to a dangerously low level and you're only monitoring the first cell then that will not help you
This is from 2S to 7S that you have 6V/5A for your receiver and your servos.
You wil have this at 2S also.
Hope tis help you.

I bought this back in January to use with my T-Rex 500, since I wanted more than 3 amps to use with a standard tail servo. Unfortunately, this BEC will not supply more than about 2.5 amps, not the advertised 5amps, without dropping voltage to less than 3 volts. I had several issues while flying, which I couldn't figure out until I hooked the BEC to an ampmeter and found out how few amps it actually supplies.I would give it 0 stars if I could.
The description of this switching BEC is misleading. It will supply 3A continuous, but the output voltage drops off at any current draw higher than 3 amps. The ripple voltage is also extremely high compared to others and what would be expected from a power supply of this nature. The heat created is also unacceptable. Power hungry servos like the HXT900 (at 500mA each) would stress this BEC if using 6 servos. The only good thing is the ability to handle 6 cells.

The BEC has almost 1V peak to peak switching noise at 2-3 Amps. At 5 Amps the output dropped to 3.5V. The Hextronic 3A BEC is much better. Glenn.
