Molding Connector For Battery Management System

02 There are many types of connectors that have been used in electric bicycle systems, but no real standardization on connector type or pinout. Choose the right connectors for convenience, safety and longevity for e-bikes systems is an important role for connecting your wires. After our first few years dealing with ebike kits and the myriad of plug types we made a decision in 2008 to standardize all of our systems to use just two connector series, Anderson Powerpoles for the high current connections (battery and motor phase leads) and JST-SM connectors for any small signal wires.

04 The connector has the further advantage that you can probe the voltage on the pins while the connectors is plugged in, making it invaluable during troubleshooting . On the downsides, this connector is not waterproof, and extensive exposure to water can cause the pins to corrode somewhat, especially any pin with a positive DC voltage on it. Our experience is that even after years of use riding in rainy Vancouver, the connection still remains largely reliable even if the metal pins may look a little weathered.
