Hi all, this thread is for planning my second ebike build, my plans are still at an early stage. My first bike, which I am commuting on daily, is this:

It is still performing very well, however I have caught the ebike bug and now must satisfy my desire for more speed, comfort, range, as well as some off-road capability.
The most critical factor is frame selection. I am looking at second hand XC and enduro mountain bikes, however the market here is both more expensive and illiquid than the second hand market in the US. I am particularly looking for feedback on what battery construction and mounting options are available these days, to try to find a winning combination of frame and battery.
I am reasonably set on using an Adappto Mini-E (will the new ones rated at 4 kW be out soon?) with the BMS, as it seems like the most well-integrated system available. The choice of motor is pretty open, but I may be constrained by dropout width, and I will prefer to run the DC bus voltage close to the limits of the controller (~84V pack).
As a starting point, between combinations of 4S LiPo and a custom LiFePO4 pack, what has the best option of fitting in a frame geometry such as this?

Specialised Epic Marathon, relatively narrow triangle but with no rear shock in the way.
