I have several 8s RC's that have EC5 connectors. Xmaxx, XRT, and Super Baja Rey. These all have the stock electronics in them. I am about to start building an HPI Baja 5b that I am pairing with a Castle XLX2 and 800KV motor. I have mainly used EC5 on all my 8s setups, but according to castle, I need better connectors for the XLX2. I am wondering if I should just go QS8 and then get these batteries. Any thoughts or experience?
