I’m building a medium/heavy lift copter (see thread here), and in noodling through some of the use cases, I’m realizing that the amount of power surging through the connectors between the dual LiPo batteries and the MK Double Quadro 2XL is potentially very high. Most people quote the current-handling capability of the EC5 connectors we’re all using as 80-100A, but even with my 4S system I routinely saw higher draws than that (although usually just in a burst). Like many, I’m running dual batteries, in part to reduce the burst draw from 1 LiPo to 1/2 the total (a deliberate simplification for the purposes of this conversation). However, like many, I was using an EC5 splitter to do the parallel connection. I realized that the EC5 connectors that form the small end of the ‘Y’ are potentially shouldering the full current draw of the copter. So in my new build, I’ve hard-wired the ‘Y’ into the main LiPo lead from the Double Quadro 2XL, and split it into two parallel EC5 connectors. I’m still concerned about the EC5 connector at each LiPo. Have any of you upgraded to something more beefy than EC5 connectors? And are there any flaws in my logic? Thanks for your thoughts!
