On all jets This size or larger I run 2 1100 A123 batteries. You probably use less than 200mah per flight, so one would be fine, but I like redundancy.

XPS used to say that 11s is best, but they said 12s can be used if using batteries with a lower C rating like 25-35C. Don't use 40C or higher cells as the wattage jumps up too high. 5000 mAa should be enough.

This fan system lasted only 19 seconds at full throttle using a 65C 12S5000mAh. It runs all day on 11S. The wire used for the windings in the Hacker motor is a little small and can t handle the higher wattage.

Which one will work best and keep me safe from damage the motor?
Can I run 65c 11s5000mAh all day and get good flight time or running 40C 11s 5000mAh would be ok to run?

You can use 65C 11S no problem. You can use the HV120, you will be pulling around 100A on 11S.
