Re: A2B metro parts for gen2

Appreciate your suggestion. I don't have a wheel motor with correct size rim/dish/brake location or a controller. I asked Grin Tech to re-lace a new motor into my old wheel with the same layout as the old wheelmotor (I was going to ship my old wheelmotor to them so they knew the proper spacing and c...

Re: A2B Metro issues

Throttle is good. Display works when powered up and shows full battery. I ordered the tool that checks phases, halls but it wont be here for a while. The bike looks fantastic but the electronics underneath seem to be made out of weak-sauce. I placed an add in the items wanted section here for used A...

Re: A2B Metro issues

Appreciate the help.
The brakes are just 2 wires for the signal.

Found some info on the phase and halls. TU.
Going to buy the diagnostic device for phase and halls and see if I can discern what is going on.

A2B metro parts for gen2

Looking to resurrect my A2B metro gen 2 with external controller mounted in bottom of main tube.
Looks like I have a bad controller and possibly a bad hub motor.
Already deep into the rabbit hole and looking to buy parts to get this bike going.

Would also be interested in throttle, batteries etc.

Re: Bad BMS or bad cells or both?

Checked voltages again and all groups of cells were the same voltage this morning as they were last night. Plugged the bms in...

Re: Bad BMS or bad cells or both?

I stopped the charge cause I was getting paranoid that the parallel cell group at over 4.2 was going to get damaged. I assumed the BMS would bleed that down and when it went to 4.24/5 on the voltage meter I had enough. I am going to try to bring the low parallel group up with a hobby charger with th...

Re: A2B metro charger

Found some of the SAE flat connectors with 12 guage wire. That is the same guage wire they used on the stock battery so I am hoping that will be good.
TU for the help!
Waiting for my new battery components to get here so I can build the new battery and see if the bike will run.

My plan is to use a new 36volt nominal battery I am building now and put it in the back saddlebags that came with my bike and run a new power lead to the controller.

Everything I needed to know in less than 1 hour.
I plan on a new battery/cells as I figured these are done. Might get up the courage to do as some others here have done and stuff some lipos in there :flame:

Re: bluetooth BMS?

Appreciate your feedback. All the cells go up correctly from 1s to 10s in approx 3.8V increments from b-0 as they should up to 38V. The last cell 10 is 38V and the second wire from b+ to power the mother board is the same 38V. I think you may be talking about a different BMS board related to the led...

Also took the cover off the BMS again. The 10th jst pin location shows a red led light on the board. (Photo attached below...
