Two points:
1. See exactly what the Torqeedo operating voltage limits are, and make sure you stay within them.
2. If using LiPo or LiFePO4, select the number of cells needed to match the needed voltages, have a charger which is compatible, and have a good BMS which not only manages the individual cells but provides overvoltage and undervoltage protection.
Other than that, no problem, as the Torqeedo simply wants to suck a certain number of amps at a certain voltage and you simply want to ensure that the pack can provide that for the amount of time you'll be needing it. Don't design for the worst-case of long-term full-throttle current draw, as you will quickly find that lower-speed cruising is MUCH more efficient.
