I have had good luck with my 10kw thunderstruck kit too. First installed 4 agm batteries 12v 220 ah. Then after 2 years replaced with lifepo4. An excellent upgrade I assembled 4 battery boxes with 3.2v 90ah cylinders. Each box 4P4S Then installed an ant bms for balancing. The monitor is very good for checking your system. If you decide to assemble your own battery system invest in a Flir Heat sensor. The Flir connects to your I phone. You aim it at your wiring assembly under load. It detects hot spot areas of concern in your connections. Battery, contactor ,controller and motor connections. 48 v 360 ah gives plenty of run time at 40 to 90 amp load.
Best regards,

Go to thunderstruck-ev.com and look at their kits. I purchased 2 ea for my 12m Power cat. For your needs a 5kW to 10kW motor should do the job. Hard part is figuring out the reduction. I chose 3:1 to get a max prop RPM of 800.48Vdc woks best. If it's in your budget assemble a battery from LiFePo4 cellsFeel free to ask me about my installation.Reuben
