Creating a 15 amp circuit with Arduino, powered externally with LiPo battery and BEC. Is using regular pin connectors safe to connect the BEC to a board? Or should this be soldered instead?
Step 1. What's a BEC?
Step 2, are the "regular pin connectors" carrying the 15A? Which pins, what female are you mating the pin with?
If you're thinking the 0.1" header pins, NO. 1A max, preferably much less.

What do You mean by that?
Links to the datasheet of "BEC", LiPo, board, please.
What devices are actually in the 15 amp circuit? The minimum wire size for 15 amps is AWG 14. Stranded wire.

Yes, jumper wires is what I am referring to.
What kind of connectors should I be using to connect to the output of this BEC for example?
I am using a shield but plan on supplying the power from the BEC to the external power terminal.
I do not have specific components on hand. I am planning to buy. As for the battery I am thinking of 1.6Ah 11.1V 3S. I only need my device to run for a few minutes.
There is no one size fits all for wire size. You need to know the current, temperature, distance, how many volts you can lose for starters. This voltage loss becomes very critical with LEDs as a volt or two will make a large difference in brightness especially with the strips that have resistors on them. Here is a calculator that will help: http://wiresizecalculator.net/ Soldering would be the best but consider what happens if you must replace it and how often. Also what is your skill set in soldering, that is important. Good Luck.
Not very familiar with your application space, but for that sort of current I'd consider using a "Deans T-Plug" or something similar. Hope that helps.

Yes it definitely does! I will keep this in mind when I receive the product. Although I am not sure if it will fit the BEC output since it looks like the wire is connected to a jr socket. This makes me question how they are able to use such small gauges when the output is rated for 15 amps?
As I said, not familiar with the application. Posting a schematic of just how this six-lead device is wired into your RC system would be very helpful in eliciting the best advice. Don't just post another image of the item, or of the reseller's web page, but rather an application sketch.
