New Barnyard Find, it's an Ohm/BionX
Appears to be well made with good (at least better than Walmart level) components. Currently inop., and I am not able to satisfactorily measure battery voltage yet.
Looks like it has some type of torque sensing control.
And regen braking.
The Previous Owner told me the battery had been upgraded (to 48V 11Ah). Also moved to a new location, locked to the rear rack instead of mounted mid-frame on the downtube.
Unfortunately she lost the key so I probably will have to resort to some destructive techniques to remove and open it up.
System is currently inop. I suspect the battery is run down. The charger she gave me I now see is rated for 26V so is probably the charger from the old battery? I have obviously not plugged it in but she likely has.
Battery sticker:
Inserting a pin into the battery charging port center conductor gets the surrounding ring to light up red and a bit of a beep so there must be some life in it:
I know BionX is a proprietary system and they have gone out of business but evidently there are some workarounds to rebuild the battery and get it back up and running.
Here are my questions:
1. What is the definitive evidence the battery is a goner? Could plugging the 26V charger into the 48V battery have killed it? ADDED: Now that I am studying the polarity diagram on the charger which shows the + pos. should be on the inner surface of the outer ring, so that transfers to the outer surface of the inner post on the battery charge port. Let's see if I can devise a way to measure that without shorting those close surfaces together. Diagram shows that pin as a NO switch so maybe that's just a simple pressure switch inside the battery charging port? Any ideas on how I can measure actual battery voltage?
2. Any ideas for unlocking/opening up the battery case for when the time comes?
3. If the PO cannot find the 48V charger does anyone know what voltage/amperage charger I need?
