hello?
My name is Jongheon Lee and I live in South Korea.

I refilled the A2B octave electric bike battery.

However, the wiring to connect the battery is complicated.

Can you tell me how to connect the wiring?

Please. thank you

Hi.

I’m unfamiliar with this bicycle’s battery system.

You might need to provide more detailed photographs.

If it is the same as the A2B Metro, the wiring diagram here might help you:

Thank you so much.

 

[glennb]

you’re welcome.

Sorry that I could not help much.

There are people here who know about A2B bikes, who could provide more help.

More photographs are always helpful.

Good luck with it.

hello?

My name is Jongheon Lee and I live in South Korea.

I refilled the A2B octave electric bike B battery.

Then I broke the power switch.

I want to replace this power switch with something else, but I don't know what to do.

The line has four strands.

Please help me..

Thank you.

Aigoo!

It will be hard to find that exact switch. It has a LED light inside. Any switch could work, the hard part is fitting the space.

Attached is a Owner's Manual for the Octave, but it doesn't have a wiring diagram.
Also attached is the Service Manual for the Metro, which DOES have a wiring diagram. They are not the same, but very similar. The Octave has a battery meter and speedometer, but the bike can run without those.

The battery connector has two large wires and a bunch of small ones. If only the main large wires are attached, the bike can run, but no battery meter.

I don't have one of those batteries to look at, but two of the wires will be for the LED indicator light, and two wires for the actual switch. Using an ohmmeter, you should be able to trace out which wires are for the switch and which go to the light. Any switch could be used for the switch part. The indicator light may need a resistor, but maybe not if the resistor is on the BMS board. I know those have a blue LED for the light.

It's actually sort of a stupid design. You have to turn on the battery before you can use it and you have to remember to turn it off when you are done riding. There is a tendency to forget to turn it off, which causes the pack to slowly drain and will cause over discharge if left on for too long.
