EBikes now being legal in NY will likely keep eBike kit prices up, for awhile anyhow.

Look at the colour of the wires and where they connect.
Sometimes I feel like those motors are cursed. I am afraid to hook up the controller that did not work to the rear motor as it might start working out of the blue.
Sensor-less BLDC operation have a nature disadvantage which is the rotor position cannot be obtain easily and correctly, especially in the low RPM range (0~100RPM). This disadvantage usually causes knocking, over current and decreased controller life. The drawback may be minimized with fast back-EMF sampling / calculating but the controller cost will rocket high since DSP is usually involved signal processing. IMO low cost sensor-less BLDC controller should never be used to drive high power motor since a single mistaken phase could destroy the controller itself.

Typical infancy failure rates for electronic components is around 25 per million. So the odds of you repeatedly getting DOA parts like you have is so low, you must be the unluckiest man on earth, or PEBKAC...

Hmm ... I would just worry about finding an LTO capable charger, not to even mention the availability of any LTO balance charger?
Those high power brushless chain drives are like bucking broncos unless I get a really expensive programable controller.
Even with a cheap generic controller the big power motors are pretty good, so not sure where you get the bucking bronco idea from. Its better to have a single powerful hub motor then a two wimpier motors, even if you find cheap motors to use for 2wd. The only way I'd go 2wd is if I was riding a lot of loose sand or mud, maybe river rocks. All those cases would also need fat tires.
12 x 2.8V = 33.6V
same as
8 x 4.2V =33.6V
I need to look for high quality BMSs
I neeed a lot of amps both charge and discharge as my LiPo chargers will work perfect for over night or 6 to 8 hour charging but out on the road when I am going hundreds of miles I will want a 15 to 20 minute charge every 40 to 50 miles. Not sure but 18 Ah should go 40 miles right ?
Of course on a trip like that I will hit a motel at least one night so can charge every battery I got but when they all discharge then the 18 AH LTOs will need a 15 to 20 min charge and EV charging stations are 240V so will need a AC outlet and 500 amp charger then I guess.
I do know however to get 500 amps @ 60V DC then 250 amps is required at 120V AC right ? I am just looking at charging options out on the road. At home I am fine with my LiPo chargers as long as I can get the 9S and 6S LTO BMSs.
My wife don't know I spent $800 on batteries yet. If she finds out shit will defiantly hit the fan.
Please let me know.
Definitely and defiantly are both adverbs, but trust us: the similarities end there. You use definitely when you want to describe something clearly, unequivocally, or without a doubt. You use defiantly to describe something or someone that's challenging or brazenly resistant to something."
