Question about battery connections!!
The ebike has a Bafag M300 Mid-motor.
I want to change my battery to another one that has more capacity. But the batteries that i found in the market have only two cabels (red and black) to connect the power. While my old battery has 4 extra cables in the middle (see photo).
Are they to turn on/off the back and front lights?
Hello.
I think it is the connection cables to the motor controller, through these the controller checks the state of the battery; I think you have to get a compatible battery, alternatively you could recell (sorry for my english) the battery by replacing the cells with more powerful cells.

@Laudix Thanks for answering
I found batteries that also have 6 Pins but I don't know how they will be connected.
(I mean the four wires in the middle)

No need for the other wires. Just for a more accurate battery status and range on display. Without the connection the bike stil functions fine. Range on display may be a little less reliable as before.

Sorry ... some things are not clear to me:
- what are the changes to be made?
- Which FW should be installed, that of the M500 or that of the M600?
- What are the benefits of this update?

The changes to be made are interchange two cables in the connection to the motor.
The firmware to be installed are the M600 with your voltage. (I can do this with the BESST Tool).
The benefits are having more power (around 900W)

Or someone know where to buy the M500 controller at a good price?
Thanks

Hello guys.

Here you can easily set speed limits and parameters of your Bafang CAN controller (all possible parameters supported only by latest M510 FC2.0)

Just cable in front of display and press magic combination on your display/buttons. Then you can unplug device.

Here is a link with more info, pictures, videos, tips and order form:
