Idea: instead of soldering the ESCs to the PDB and the FC, I want to use battgo plugs between them. Those have the usual 2 power cables, and a smaller one for data. However, I have only found battgo connectors in xt60 size, which would be too big. Does anybody know where I could buy some xt30 connectors with battgo?

I ordered some from Ebay.  I am in the US, so that is where the following post is from...but they are available from Europe as well.

Not seen any BattGo batteries in smaller sizes (<1300mAh) as yet and doubt they'll bring it out when the XT60 version is still rare?

If you're after just current sensing, then you can always use one of these:

Thanks for that jimbo, good idea. But no, my idea was that the ESC signal could go through that connector, so I could easily swap ESCs

kaitylynn, I was looking for ones that have one extra wire
