Also I’m using throttle only, no pedal assist.

Can cause problems because of the old adage, the more wires and stuff you have the more that can go wrong. Then for a person like you, new, first ebike build, troubleshooting could be a challenge so good on you for going throttle only :thumb:
So ya just imagine if you went with a display kit like a KT, even more wires and even more stuff
Countless people coming into ES with an error code on their display.
Bafang G310 (250w nominal) rear hub from Grin. I paired it with a Grin C-4820-GR_Higo 36v-52v sine wave controller. Then I purchased a 52v 13.6ah battery from EM3EV. Did I buy too large of a battery?
I believe that controller is 25A, I remember looking at it or something similar yesterday browsing for a Sinewave, FOC with regen. Your battery is probably 40A so your good there.
52Vx13.6Ah=708watt-hours so depending on how much you pedal, hills, terrain, wind, your body weight, cargo, you'll probably be doing all right with range. 30wh/mile (20wh/km) will net you 23 miles or 35 km.

Minimal Assist (using motor only on hills, slower ~30kph setup) 6-8 Wh/km
Typical Assist (~40 kph with pedaling, motor on all the time) 9-12 Wh/km
Power Hungry (either no pedaling, or hauling a load, or going really fast) 14-20 Wh/km
