Esc doesn't work with two batteries anymore.

I plug in each battery separately and it works fine, but when I connect two in series the esc doesn't turn on. It use to work. Any idea?

what esc have you checked all you series battery plugs?kinda hard to diagnose a issue without alittle more detail.,, it could be a bad plug contact or even a broken wire inside insulation..

 

[tntpoof]

do you have a vom meter?.if you do check the resistance of every plug that will tell you where things went bad or no connection.

vom=voltage ohm reader..

Bad solder joint some where.

Thanks guys, It must be the serial connector is faulty. I inspected it but it appeared fine. I'll look 8t over again.

visual inspection will not see a bad solder joint or a broken wire covered in its insulation..

Use a volt meter
