I hope I've come to the right forum about this...
I'm planning on building an e-bike using RC components, except I'm not going to use a transmitter and receiver. Instead, I'll use a Servo Tester to control the speed of my brush-less DC motor. The motor is driven by an ESC (Electronic Speed Controller) which in turn is controlled by the Servo Tester.
I'm planing on using LiPo 6s(22.2V) battery.
Ive researched for several days now and came found that I need a BEC (Battery Eliminator Circuit) to lower the 22.2V to 5V so the servo tester doesn't get damaged.
Now Im just wondering about the current.
Ive seen some people have a separate battery for the servo tester which seems to be the simplest solution but I want to be effcient and use my main battery for that.
Im thinking of splitting the cables to go to both ESC and BEC -> ServoTester.
I know that the setup is going to draw a lot of current maybe up to 50A or more (not continuously) so then I'm wondering if that current is going to go through the BEC and then into the servo tester and fry it. Or will most of the current choose to go through the ESC and only what is needed goes through the BEC?
PS. Im not an electrician x)
This is how Im planning to connect everything Please dont laugh:
Will this setup work or should I stop trying before I get hurt? :)
