He makes a lot of good points. Essentially, if you have a charger that can balance all the cells, you don’t need to use a BMS for that purpose.

Obviously that’s on a sweat-soaked multi-hour fitness ride, but you get the point. By adding more of your own pedal power and using lower pedal-assist modes, the range of an e-bike can be drastically increased, which is where manufacturers often get these lofty range figures. Connect up the controller directly to the LCD, battery, motor and pedal sensor. There is no cable loom.

If the location of your cage bolts do not fit the slots on the mounting rail, you may need to install one or two rivnuts (usually M5 rivnuts) on the downtube.

The main role of the BMS in a e-bike’s battery is to make sure all the cells of the battery are in balance during charging and discharging. After you measure the output voltage, you do what’s called the “light bulb test” — where you use an incandescent bulb hooked up to the outlet. This is easier in America (or Japan I guess) where the voltage supply is 110V, but it still works with 220V bulbs. Ultimately, most people aren’t going to ever hit efficiencies below 5 Wh/mi, unless they are really pushing it hard and getting a serious workout. For daily riding, 25 Wh/mi on throttle-only riding and 15 Wh/mi on modest pedal assist riding are both good figures for real world range estimates. An LCD control unit relays rider information including the five different levels of power assist, trip computer, speed, journey time and battery voltageStrict and Outstanding Front Details】Electric bicycles are equipped with ergonomic handlebars and brake levers,(electromagnetic induction) will automatically cut off the power when braking, which has a good guarantee in terms of safety and durability.LCD display (digital control) (display function) (setting function),can display battery status,time,mileage,gears,faults,etc. SWX02 48V 250W rear hub kit Hubkit with Bafang SWX02 26" or 700C Wheel and 48V 12AH HL Battery Very high performance conversion kit, high torque winding, low noise motor, plug and play easy wiring.
