Hey Dan - thanks for checking in.
Those 12 motors really wake up when you hit them with 100V. In a 20" tire you can produce phenomenal torque. Even paired with a tiny 6 fet controller you can rip them hard... and Justin's 6 fet controllers come off the line with 100V fets. You can crank them up to 40A or even more... and given the match of Voltage to KV to wheel diameter... the controller can take the hard off the line punches and settle into a cool running temp. It all adds up to an ebike that is not "coggy" off the line, has tons of stall torque, can reach speeds in excess of 35mph, run reasonably efficiently, and you dont need a giant 24 fet controller or huge 30Ah battery to make it happen. Some low cost high rate cells... mmmm....
As to BMS... I was lucky to be contacted by a recruiter just today who is looking to fill a BMS R&D position here in the valley. Distributed high reliability low cost systems that can help us settle on a standard sooner rather than later. Tesla has been rocking it... and their Palo Alto facility advertises (in a double life size poster) that any and all are welcome to step on their patents... but... its still a bit of a closed protocol that I am not seeing in too many other places. We need to get the show on the road and get everybody using the same "legos" so that we can get some interoperability between manufactures.
For this technological revolution... Ford can work with Chevy, Toyota can work with Honda, China can work with the US, -> We can all work together and the end result will be good, cheap, sustainable power.
As to divorce court... yea - uh - I have had to learn a whole new level of patience and mindfulness. Family court is unlike criminal court. If one co-parent wants to come out swinging with bad-ass lawyers then you are basically guilty until proven innocent and no amount of logical arguing can undo the mess. The take home from family court is this:
* They are not there to solve family problems. They are basically there to mediate, enforce, and hit the brakes when requested.
* Lawyers come in 3 flavors: Skilled negotiators, Paid fighters, and straight up disruptive blood sucking psychos.
* The name of the game is staying cool, jumping through hoops, following direction, co-parenting, being patient, and playing the game.
* Even the lawyers will tell you... there is no solution to family issues in court. It will empty your retirement accounts, drag everyone through the gutter, and it disrupts childhoods.
* The only resolution comes when both parents agree to drop the bullshit, accept reality, co-parent, and move on.
In my case... its been in excess of $100,000... 24" of paperwork... endless court appearances... the worst kind of money grubbing...
I just focus on my son. We video every day since my ex absconded with him to her parents 400 miles away. He and I maintain our connection while his mother comes to terms with the new reality. My lawyer is ready to retire. Fighting my ex wife is like trying to tear a T-Bone steak out of the mouth of a pit bull. Sometimes I just have to walk away for a while and let her have her gnaw on the bone.
In the end the only thing that matters to me is how well adjusted and capable my son is when he starts integrating with society... and that he is not an emotional wreck that requires big pharma medication just to cope.
K... off to my next meeting for the day.
Increasing battery voltage and controller current limit will result in a non linear experience
