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...

It's 9 pins.

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.

Hello, Is there a standard wiring diagram for a 5 connector to 1 connector (Julet connectors) wiring harness? I am replacing the motor controller and the new controller does not have Julet connectors. cheers, Daniel

Hi, I am trying to choose an appropriate motor controller for my bike. I have a Bafang 36V rear hub. I checked the wiring to old motor controller. It has 3 phase wires and 4 other wires (hall wires?). The display panel is a "790" (see picture below). How do I choose an appropriate...

TheBestie, I was wondering, do you think it would be easy to mod this alarm to ramp the volume up from 110dB to 130 or even 140db?

Thank you guys for all your suggestions. HamsterPower, I am keen to see your project! Also, TheBestie your vibration alarm sounds like a great idea!

Hello, I was wondering if people have any suggestions about how to stop my bike battery being stolen? (when carrying with me is not an option) Perhaps some ingenious ways of locking it? n.b. I will be assembling my own battery.

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...

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.

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

Hello, I was wondering if anyone can please clarify the costs and potential pitfalls of importing a bike battery vs importing individual cells into israel. I should note that this is a one off thing. I do not intend to do it for commercial purposes. I am currently considering assembling my own...

Thank you everyone for your replies.

Thanks for the link. Unfortunately I did not see any 13S BMS board there with battery temperature monitoring. Any other ideas?
