Fats Flyer Posted November 3, 2008 Share Posted November 3, 2008 Hi All,Can anyone please tell me , what is the receiver voltage through a speed controller and using a 3 cell lipo please.And , is the receiver voltage the same regardless of what size battery is used.thanksvince Quote Link to comment Share on other sites More sharing options...
Michael Dearden Posted November 3, 2008 Share Posted November 3, 2008 As far as I am aware there is a "built in" voltage regulator (can't think of the correct name for it right now) in the ESC to ensure the receiver gets its right voltage so no need to worry about that as long as the ESC is rated for your battery.

Fats Flyer Posted November 3, 2008 Author Share Posted November 3, 2008 Hi Michael,Thanks mate, but i need to know because i want to make my own led light circuit for my eurocopter ec-135 helicopter and before i order the bits and peices , i need to know because they have different values.vince Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted November 3, 2008 Share Posted November 3, 2008 Most speed controller BEC circuits will supply 5V constant to the receiver, and yes this voltage will be the same irregardless of the battery supply. If you wanted to double check....stick a meter across the wires of the plug from the ESC which goes into the Rx. As stated...ensure the ESC can handle the number of cells you plan to use in the main battery. Quote Link to comment Share on other sites More sharing options...
Michael Dearden Posted November 3, 2008 Share Posted November 3, 2008 BEC! That's the thing Timbo. One thing you'll find on this forum vinnie is that you can rely on Timbo to sort most things out for you! Mind you, I got this one right!

Fats Flyer Posted November 3, 2008 Author Share Posted November 3, 2008 Cheers Timbo,Thats great , now i can make up my led light setup based on getting 5v leds and also the resistors to go with them.much cheaper to make my own.cheers guys vince Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted November 3, 2008 Share Posted November 3, 2008 I doubt you will find 5v LEDS - they usually come in lower voltage flavours than that around 2V is quite normal - its the current that will kill 'em, so you need to insert a suitable resistor in line with them to drop the current to a safe level. Many LEDS start at around 20 -30ma current draw, but several are quite a lot higher. generally speaking, the higher current ones will be brighter. Heres a chart for you.

Fats Flyer Posted November 4, 2008 Author Share Posted November 4, 2008 Hi Timbo,Thanks for the link. Yes, maplins and rapid do 5v led's.Ive spoken to one of the guy's at rapid's and worked out which led's and resistors to use.When i get them and make a circuit ,i'll let you know how it went.Timbo, you are a mind full of information, many thanks.vince Quote Link to comment Share on other sites More sharing options...

Tim Mackey Posted November 4, 2008 Share Posted November 4, 2008 Yes thats quite right - any LED of any "voltage" can be run from any supply - its just a question of ensuring the current limiting resistor is of the correct value, and as you say sometimes these are fitted within the led itself - as are sometimes microsized flashing circuits to produce an off the shelf solution for a flashing LED Quote Link to comment Share on other sites More sharing options...
