Lawrence, Go to LunaCycle.com and look at the Bafang BBS02 mid drive. These are far more versatile than a hub motor because you can use the trike's gearing, making real-life hills MUCH easier. The BBS01 is officially a 750W system, but LunaCycle hotrods it (reliably) to like 1300W. Not sure what the BBS02 tops out at - it's officially a 1000W system.
It's possible hub motors get better peak efficiency, but mid drive e-bikes have shown their superiority in real world use. LunaCycle also makes battery packs with various 18650 cells with built-in BMS. Spend some time on their site.
