BBSHD and BBS02 wiring pinout

[paxtana]

Same pinout for both BBSHD and BBS02

[M 2.0]

Would this be the same for all BBSxx? If so I can correct the title.

[muttleytm]

What are these various color wires for? I can't tell from the abbreviations;

1 Brown P+ ???
2 Orange PL ???
3 Green Rxd ???
5 Yellow TxD ???

[max_volt]

Connect P+ and PL together to power the system up. serial data rx/receive/in and tx/transmit/out . Derived from Latin.

[muttleytm]

Does is P+ just split of from the blue wire #6 on the main harness and 5V+?

I guess I'm trying to figure out what buttons the different wires correspond to. I have a Luna DPC 18 display and the control for it has three buttons in a triangle and two more on top as a - and a +.

One of them looks sort of like a headlight symbol you might see on a car. In reading the manual I see it sounds like this is the one that turns the display on or switches it to night mode, which maybe is actually off. One of the other switches is a power symbol so I imagine that powers the whole system. The other button is an "i". I assume this is for programming or navigating screens.

It the one that looks like a light symbol is just a switch I'm wondering if I may tap into this for controlling something else. I'm sort of switching gears by using this kit for a bike I was starting to build. The one I was building had an "ignition switch" which would turn a different controller on and a central light switch. They both mount on the handlebar and take up space. I assume the switch with the power indicator would be the "ignition switch".

note there are 2 different versions

I’m looking to go stealth by removing my display/paddle assist/on-off switch and would like to add a key voltage throttle like this https://m.snapdeal.com/product/ebike...h/644503289733.
I know the red black & blue wires from the 3pin hardness connection are the throttle signaI wires, I believe I need to connect P+ brown wire & Pl orange wire from the 5pin display hardness connection to the on/off switch (not sure) . but I don’t know which wire to get a voltage signal from. Is it the yellow wire?? Not even sure if one of these types throttles can be used on a bbshd 1000w Bafang mid drive?? If anyone ever tried please let me know. Any advice is greatly appreciated.

@Albeegood,

Voltage signal as in for the battery LED display indicator input?

As the P+ (Brown) pin/wire is full battery voltage. That is where you can get the input for the battery voltage indicator. To be more accurate... P+ would go to the input side of the key switch, the side that's not powering the LED. With the other side of the switch connected to PL (Orange) and the input to the LED display.

The Bafang uses a hall sensor type throttle. The link for your throttle doesn't specifically say. But typically most Ebike throttles are, especially the lower cost ones. Try to find out from the manufacturer.

Just enquiringly about the wiring out from the BBSHD. I understand the gear sensor, the speed sensor and main battery connection, but what is the 4th connector (small pos+ and neg-) for?? It does not appear on the diagram above.

[paxtana]

Probably a light.

[MadDias]

I´ve got the same question. What are these red and black wires for? They aren´t mentioned in any wiring diagram I´ve seen.
There must be someone on the internet who speaks chinese and can ask Bafang what this wires are good for...

[paxtana]

There are multiple controller versions and some have a output for light which puts out either 6 volt or 12 volt

[simon.magrini@gmail.com]

I have a e-bike modded by bafang kit.
I bought a bike light without internal battery powered by usb cable.

https://it.gearbest.com/bike-lights/pp_602417.html?wid=1433363

I think to use the 5v alimentation of the brake cable .
What do you think about?
Thanks

[kerrylaw]

I would not do it. You have no idea of the current capacity of the brake circuit and could burn it out if the light you want to connect overloads it by drawing too much current. Why not just tap the volage, ( 36v/48v/52v ), that is available from the battery cradle? Buy a "Buck Step Down Converter Regulator Module" , also known as a " Step Down Buck Power Supply" from Ebay. Find one that will accept your battery voltage and knock it down to the voltage you need ( +5vdc? ) Just make certian it will provide enough current. ( 3amps or so )

Something like this....

[Albeegood]

Tommycat thank you for your reply. Yes as in battery indicator. I won’t miss the paddle assist when going stealth but I want to know my battery voltage as it drops. Again thank you so much. This is very important to me.

[Tommycat]

Your welcome! Glad I could help. Ran across this thread that may offer more tips on going "No Display"

Best regards,

[Albeegood]

Thanks for your help Tommycat . Today the voltage throttle worked without any problems but decided to leave it as it was because the new throttle had some lag to it. It maybe was my settings, current or speed throttle response but didn’t want to go no further. The good thing is now I know I where to get voltage from if needed. Thx.

Hi. Trying to fit Bafang DPC-18 to 350W mid drive. Bike came with King Meter display and had male green connector.
New display came with female connector.. Motor has female connector! Can anyone suggest how to adapt??

[AZguy]

Bafang mid-drive?

[Black86Panther]

Hello everyone, I bought an ASI Bac 800 controller for my Bafang BBSHD. Unfortunately, the Plug and Play cable is nowhere to be found. Has one of you happened to have the pin assignment of the controller of the BBSHD Pas and Hall sensor so that I can build a cable myself. In the original cable, the wires from the Pas and Hall are put together. Which are they?

greetings from Germany

Hi,
I have a 250v/30a fuse between the motor and the battery. Need to know if it's a slow blow or fast blow fuse. Thanks

Mark

[MadDias]

Don't know if that's international, but there are at least three types of those fuses. There is F (flink) for fast, FF for very fast and T (träge) for slow.
Hope that helps.

[fournival@gmail.com]

[AZguy]

What are the numbers stamped on the fuse?

FWIW there's not just fast and slow, but all sorts of fuses. Fuses usually have two primary ratings - the current which is the continuous current it's designed to trip at when at room temperature (it's really more complicated than that though) and you should not run more than 2/3 the rating continuously since this will age the fuse - and the I^2·T rating which has to do with how fast it blows among other things like aging and surge/in-rush current

[FIDIG]

I pulled the wires out my thumb throttle anyone know where they get sodered to on the throttle. Is there a diagram showing where the wires are attached to the throttle?

[AZguy]

Throttles are silly inexpensive - why not just replace?

[Tommycat]

Hi FIDIG,

Here is a pin-out diagram for a typical hall sensored throttle.






If the wire colors hold true from the harness to the throttle's wiring cable according to the wiring diagram above, the output wire would be BLUE. If unsure, verify the pin-out locations on the connector to the correct wire color using the pin-outs shown in the OP's diagram. Remembering to reverse, or mirror the pins, for the 5vdc and ground pins. As you will be on the opposite side of the diagram's shown connector. (male side instead of female...)
