Since there is a large size difference between the 2 chains, would the 25H be any weaker considering how much smaller it is

The strength of the metal also plays a big part. It is possible to find high-quality and strong 8mm chain, and of course you can find weak #25. That being said, the #25H (H = heavy duty), should be very strong and when used in the high-RPM half of the reduction (high speed / low torque), each link is less loaded than in the secondary (lower speed / higher torque).
a 25h chain on the primary should be strong on the primary more than a 25h chain on the secondary right side?

I asked the same question of Ed Lyen, the controller wizard, and here is his response: "From what I have learned, the BMC controller is designed to work with motors that is equipped with 60 degree hall sensor spacing angle, including the BMC V1, V2-S, V2-T, V3, V4-T, and V4-S. Whereas the Lightning Rod mid-drive motor utilize the 120 degree hall sensor spacing angle. The BMC controller's spacing angle is fixed. Therefore, it is considered incompatible." Sorry, I was hoping to use my BMC controller on the mid-drive kit, also.

I'm wondering about this also as I don't get the same acceleration on my LR kit using a EM3EV controller than I used to on my Mac motor with the same wattage drawn. I thought the GNG and LR motor are the same motor.

If the LR kit uses the same motor, then Lyen says it is a 120 degree motor which means the BMC (and likely the Mac motor as I think these are very similar motors) are 60 degree motors. Perhaps this means that EM3EV controllers are not compatible either and thus my slower acceleration??
