switching from molex to JST battery connector on quadcopter

       Remove this ad - become a site supporter!
Hi there,

I'm new to the RC quadcopter hobby, I was just wondering if there are any issues with switching the battery connector on my quad that accepts a molex connector right now (for a Syma X5c-1 copter) to a JST connector (with some simple soldering)? I mean, it's just the connector, right? I don't have to worry about frying the circuit board or anything?

Any input is appreciated...

This forum is for RC Electric Helicopters. Your question may be better placed in the mult-rotor forum here on RC Canada.

Re: switching from molex to JST battery connector on quadcopter

There are no issues with changing the connector to JST as long as you maintain polarity. Mixing the positive and negative leads is what can fry boards.

The standard JST connector requires crimping. You could crimp and solder the pins, but there are mixed reviews on this method. Some feel that solder prevents the wire from slipping, some feel it creates a hard break point when stressed.
