I have this same problem but only when i charge my battery because i charge it with alligator clips and the clips are connected to the charger with a tamiya plug. I use duratrax powerpole connector on all my stuff, motor battery etc..
they are made out of silver and it like having everything hardwired. they're the best. here is the link.
