Which one, Samsung ou LiPo? The Samsung one should be good for 2C (20 Amps) and 3C Peak but I guess the BMS may limit current to 20 Amps. They say standard 5 Amps but for most 36 V controllers standard nominal is 7 amps.

At the moment my controller is set to 18 Amps and I have seen the motor drawing 15-16 Amps tops from a 10.4 Amp Samsung cell battery in that casing.

I went for a ride despite the 37°C and bright sunshine or, because I have a pedelec, I could ride and without much effort. I saw 46°C on one exposed street thermometer panel which felt about right when riding in direct sunlight on sealing which has been warming up for three whole days and at 4:30 p.m.

Not much effort and about 7 km of climbing, some at 12%, does require quite a few Wh from the battery. I would say that I am probably getting 50 km from a full battery in these conditions. That is about 70% of what I was getting with the hub motor but the controller is able to draw 16% more current. The bike is also slightly less efficient when climbing (motor more, big wheels less) so the math looks about right. That is about 12 Wh per mile which I think is right spot on @trex and @flecc's average Wh/mile estimation for ordinary riders. Do not fear! When the weather gets cooler I'll go back to being a "do you really need an e-bike?" rider at 10 Wh/mile.

Your TS motor miles may vary on the above but you will only be pulling peak 16 Amps and not 18 Amps like I am.
