Just bought a brand new 2022 (NOS) Sector E1 with Lithium upgrade. (Single 135ah/200amp continuous). I've climbed a moderate hill in my woods probably 20 times since buying it. Today It won't climb it unless I am in Low. In High it almost makes it and then completely dies and I have to roll back down the hill. In Mid range (Max Range) I can't get 2 feet up the hill and the power output in only 100 amps, I have climbed this hill in every speed before many times. I put it on the trailer tonight and it wouldn't even get on the dang trailer in mid range. Torque is gone. That being said, when I am just cruising around in Midrange, it runs absolutely perfect with plenty of power. The only thing I did was charge it up, that is all. I charged to 100% using the charger that came with the battery. Before you think the BMS is shutting down due to overcharge protection, remember I am going UP hill so there is no regeneration AND I have done it before at 100% charge AND another big problem is that after 1 mile it is already down to 85% so it's not over charging and why is the battery draining so fast when I got 27 miles before. Battery output is fine in Low it pulls 200 amp up the hill just like normal so that doesn't point to the battery being the issue. All the individual cells on the battery are in line, so there is no dead cell either. I am tech savvy but to toward electric motors and I tried to cover all my bases. Please don't tell me basics like torque is reduced in High and Mid. The only thing I can think of is that I smelled something when I took my first drive today and I thought it was the Ebrake dragging but there was the correct amount of play in the cable and I jacked up the rear wheels and they spin freely. maybe something burned out in the motor, I do not knowm still runs great, we'll see if I have any trouble on the hills at the lake house this weekend. Maybe this is "Normal" and the settings were off before and was giving equal torque for whatever reason instead of 50% in Mid and 70% in High like the manual says....
For reference....this is it not even able to get on the trailer in mid range

I have a Coleman Outfitter 550 purchased in January 2022 that runs and operates pretty well. 65 hours on it so far. It is a work vehicle for my 10 hilly acres with two 1 acre woods and 5 acres of "lawn". The rest is under a lake.
My parking brake does not seem to have any grip. It worked when new but after a month or so, it is just almost useless. I press the parking brake pedal hard until it stops. Still, it won't hold even on slight inclines. I don't see the caliper move as I press the brake pedal down. There seems to be plenty of pad left on it and the rotor is shiny as if it is rubbing a little when applied, but not enough to stop it from rolling.
Any thoughts on possible causes?
