Hello everyone,
Ebike DIY enthusiast posting here, wondering if I can get some help/advise on wiring connection between -
1. hailong USB port,
2. USB step down module
3. battery
4. on/off switch
Do I just need to connect wires circled in red to the battery pack discharge wires, and the wires circled in blue to the usb port?Is there any link to any wiring diagram for this. Thanks
