Thanks Gregor, the issue happens even charging at low current and running alone in the power supply. I tested charging a single 6S battery at 10A and the issue is there.

Hi Tim, I have replaced the stock EC5 for a better 4mm bullet (4.0mm "Super Bullet" Solid Gold Connectors
). I'm electrical engineer and ran some tests to check how good this connector performs. They have a resistance of about 0.25 mOhms, I mean, a voltage drop of 15mV for 60A.
Running at full power (60A), you have less than 1W of losses per connection - they don't even get hot. All PL8 I've got for my friends (10+ units) I replaced the stock for this 4mm and all performing great. I even suggest Revolectrix to run some tests and think about this connector because almost all power supplies in the market have 4mm output.
