This is the opposite form of the way this issue has come up on ES in the past, which generally tries to use a generic battery to replace the BionX branded one. I've read the hundreds of great BionX related posts on ES, and am fairly certain that what I'm attempting to do can be accomplished.
I have a 48V (Canbus) BionX battery that's only about two years old and has had mostly prototyping and light experimental use. The cells are all balanced and in good condition. I have a full assortment of BionX components, including the G2 console and dealer diagnostic tool (BiB?) I no longer wish to use the BionX proprietary system, so have started converting the BionX motor into a generic DD BLDC hub motor. I followed the wisdom of Justin and the ES BionX gurus in undertaking this task, and am well underway with that process -- with a possibility of even reusing the BionX affixed strain gauge on the axle with an instrumentation amplifier developed for another bike setup.
At any rate, I don't want to throw out the BionX battery, nor do I want to sell/pack/ship it due to the volatile nature of this type of thing. I just want to use it up on one my other ebikes, especially on one with a new Phaserunner and Grin All-axle motor. My current issue is that when I "turn on" the battery using the Power button (on/off switch) on the G2 console/display, it lights up the display and shows the battery as being fully charged, BUT it displays the "POWR PROT" (note spelling) message. The result of this is that the power output ports on the battery remain dead. That error message, per the BionX documentation, suggests a bad connection between the console/battery and the (BionX) motor. The BionX motor (and its internal controller board) is never going to be connected, of course, so I want to override/ignore the error message, not fix it.
There are some suggestions out there that a temporary short between pin 3 on the D-sub battery connector and the A1 (ground) pin on the same connector will "turn the system on". Having some bad experiences on this system with poor choices related to "shorts", I wanted to see if there's a way of turning the battery's output ON and keeping it that way that doesn't require a lot of BionX magic, or risk release of the magic smoke. Changing connectors, taking apart the battery and doing rewiring, that I can do.
