I’m hoping this is a simple one but I’m having an issue connecting my electronics. I used an almost identical setup to Guldsteen except that I’m using 2x6S 20,000mah lipos. For the BEC I’m using a castle creations 2.0 waterproof. The other difference would be that I soldered the BEC to one of the batteries and not after the series connection.
I tested the setup with just 1 battery and it works well. However when I connect both batteries in series and bring it up to 12S, I have fried the receiver. I tested the output voltage out of the receiver at both 6S and 12S and it is a solid 5.2V, so I believe the the BEC is working properly. I believe that I’m connecting the terminals correctly and it works at 6S so at a bit of a loss what to do next.
@michion I gave that a try and I’m still getting sparking when the circuit is in 12s. The output from the BEC is 5.2V but between the receiver and the input to the ESC something is happening because they both are sparking.
Did you know sparking when you connect your batteries is normal? You need to use antispark connectors to eliminate this. AS150 or XT90S are good options.
Maybe load a photo of your setup so people here can try and help.
Connect the power from your BEC to CH1 and also just the signal wire from the esc into CH1. You will need to rearrange the pins if you only have 3 pin connector.
I believe thats how I had them connected when I was using that type of receiver.
