    Re wiring diagram for a 5 to 1 wiring harness

    Thank you! So there is an additional connector (3pin). I have no idea what it is for but in case it is not used. I will not use the display connector as it already has it's own cable that connects directly to the controller. The two two-pin e-brakes are just switches so no polarity issues...

    Re wiring diagram for a 5 to 1 wiring harness

    Sorry for the slow reply!!! I have been having a crazy month. Actually, I am referring to the headset on the front of the bike. So that is the brake levers, throttle, display etc.

    re how much to spend on a battery charger

    Ok, so it is the version which is modded for 48V, 500W (auto-ebike.com). I am not sure exactly what the kits consumption is. In terms of range about 30km (I will be taking it on steep hills). I am planning to make a 13S, 5P out of the GA cells. I will add a BMS battery system. In terms of...

    re how much to spend on a battery charger

    I am planning on using a BMS. About the balancing, does bleeding have any major disadvantages (except for charging time). Are there BMS systems which charge individually? Is it worth considering such systems?

    I am going to be using sanyo 18650GA cells. I haven't decided which BMS. The controller is included in the motor which is a tongsheng TSDZ2.

    re how much to spend on a battery charger

    Hello, I am building a custom 48V battery (13S, 5P, 17.5aH). I am considering which battery charger to buy for it. I see that it is possible to buy chargers starting at $20 and upwards. I am wondering what my considerations should be in terms of price and performance. cheers, Daniel

    New "TSDZ2 Torque Sensor Central Motor"

    The controller is in the same housing as the motor, I presume? What is the 1500W boost converter? Edit: Ok, an answer to my own question: a DC-DC converter.
