Questions about inner controller of BMSBATTERY

[Iberian]

Hello, I introduce everyone to endless-sphere, this is my first post.
I have a aluminum road bike, 28" wheels with steel fork. BMSBATTERY components.16A 36V battery, Bafang front engine BPM2 328 RPM 350W 36V KU93 controller with which I am very happy to travel with it. It runs at 45 KM / H in flat. I present it to you:

Now I introduce you to my new acquisition.A Berg Trailrock aluminum MTB bike, 27.5" wheels,hydraulic brake discs,cassette 9s. I will turn it into an electric one, my intention is to use it to climb hills and a basically use of road. I want a light bicycle that climbs the hills well helping her with pedaling. I am a trained 80 Kg cyclist. 1.80 m:

My intention is to place a Bmsbattery Q100C CST 36v 201 RPM 32 Holes rear engine:

And this 48V battery 2.9AH SAMSUNG Cells 48V 14.5AH with internal controller.Includes PAS, display, throttle and brake levers:

I have made a sketch with GIMP of the project

I know that there are people here with experience in rolling Q100 36v to 48V motors.
Do you think the combination I want to make a good idea?
The main question is what features does the internal controller of that BMS battery have?
Does anyone know?

On some batteries with internal Bmsbattery controller, they specify the following: "If you choose inner controller, will have a 18A sine wave controller."
Going for a while I have located this:
http://www.topbikekit.com/10s13s14s-36v48v-6mosfets-sine-wave-controller-for-hailong2-case-40pcs-cells-p-759.html
I think the internal Bmsbattery driver must be the same or similar.

Please if anyone has more information about this inner controller, it would be appreciated

Sorry for my English, I am Spanish.

I use the Q100 on my low powered bikes. I'd suggest the extra power of the larger Q128 for a nice bike like yours.

Hello docw009, I'm going to make the wheel. My bike has 27.5 "32 holes wheels, in bmsbattery the q100c cst is the only engine they sell with 32 holes.
That is why I have thought about installing the q100c 36v and boosting it with 48v. I prefer the one of 201 rpm because I give priority to the power and torque for this bike.
My main interest is to know the characteristics of the inner controller that I indicated above

 

[knutselmaaster]

I use the so called inner controller for the 50 cell hailong cases quite often, it is the same as the s06s controller in both power and behaviour.
This hailong2 case controller seems to be similar.

Thanks knutselmaaster, I think with that 42v inner controller I will not toast the Q100cst

 

[knutselmaaster]

The best thing to do is to use your display to set max power, according to the motor.
The (135mm wide) q100cst is only a 250w rated motor so you'd better not give it 100% of a 6 MOSFET controller (under heavy load)
The 142mm version of the q100cst (which is in fact a q100h-cst) is a 350w rated motor and a lot tougher.

The bike will be slow w/ the low-speed rated (201) CST on 48 Volts, even with the 27.5" whl.s. Maybe 20 mph. all out, flat ground, no pedal. 52 Volts would add about 2 mph.
The problem with the CST is that it is only available in low-speed (201) or high-speed (328) and the "best compromise" mid-speed (260) is not offered. Some very fit cyclists have used the 328C, but there are problems, more as the whl.s get bigger. It for sure would be a poor climber compared to a 201, 52V 20A controller, 26" whl.s combo.
A higher Top speed may be a moot point with that bike. It appears to have a typically sm. mountain bike chain ring and from the pic, it appears there is not much room to fit a larger one without installing a crank with a wider bottom bracket.

 

[knutselmaaster]

The 201rpm 36v does about 20mph @ full 36v battery already (42v) on that wheel size. (No load)

Thank you all for the help, I have finally ordered Bmsbattery from Q100cst 350W 201 rpm and 14.5A 48V battery with inner controller.

My bike has a 135mm space to place the engine.
I'm not looking for speed for this bike, I want torque and power to climb hills. 20mph seems enough to me.
I haven't asked for a Q128cst because Bmsbattery doesn't sell it with 32 holes. I think that with 48V and 201 rpm I will have enough power and torque to climb.
When the order arrives I will send here some photos of the assembly and final result.
