The difference with the Vado is that the button/LED are on the battery.
It may confirm this:
So 3 separate parts, motor and battery, which are generic, and the controller which is developed by Specialized.
Specialized already uses an interface plate to mount the motor, so it may be as easy as changing this plate.
The new motor will be priced higher, for a while at least. And if the battery is bigger it will have a direct influence.
Sure... A T6 output something like 1'000 lm... So yes, with 50 LEDs and 500W you may theoretically have something like 50'000 lm! :)
I have a BL70s light with a DC/DC converter on my Brose motor. It's an XHP70.2 LED which in perfect conditions can output more than 4'000 lm. In this light, it's...
The issue is that it's not "just" a cable.
Maybe it's a DC/DC converter from the 36V of the battery to 6V...
The real question would be what is the output on the motor connector?

The limit is 160 Wh, with a maximum of 2. In a future with smaller stackable batteries, better to go with 100 Wh as the limit is...
