Hi.

Base for my build is ATV Adly SuperSonic 50

The previous owner hasn't used it for the last few years, so there will be a lot of work to refresh some key elements
It is factory fitted with 50 cc engine, but frame is identical to all chinese constructions with motors from 50 to 300cc
Dry weight 155 Kg looks promising.


The vehicle has to be as light as possible, I don't need range. 1 hour of fun is enough for me
Since this is my first build, I have limited my budget to around $2,000.

After disassembling the machine and measuring the available space for the components, I started looking for a suitable battery.

The choice fell on NCM cells from LG, model P41 (used in VW qroup electric cars)
Below is the single cell spec.


Battery will consist of 20 cells in a 20S1P system
These cells have aluminum and copper connectors, so connecting them in series requires specific connection methods.
I chose the method, using FR-4 laminate sheets, rivet nuts and aluminum flat bars that press the cell joints together.
All cells, after assembly are glued together using Super RTV silicone from Wurth





For BMS – ANT 400A (1000A)
Battery is enclosed in an aluminum casing.
200A rated, 8mm bolt battery ports



Battery is tightly fitted inside using Armacell elastomeric foam, wires inside are 25 mm2 (AWG4)

​

Battery and Driver connection cables are 35 mm2 (AWG2)

I bought a relay (SW181 72V 200A DC switch ZJWH200A) but I was surprised by its weight, size and the fact that it heats up so much during operation that you can get burned.
I don't install it.

Currently I have everything wired up and I am starting to have fun with programming the controller.
I bought the whole set from SIAECOSYS.
I am not convinced that the controller is pre-programmed to work with the QS138 engine.
Below are screenshots with the initial settings that I made while studying other threads and guides on YouTube.
I would be grateful if you could find the parameter that I have set incorrectly
I don't know why the program doesn't read the driver version and its software.



For now I tested the work on the stand without load and the drive works smoothly.
I think that next week, I will put it together enough to do some test drives.

How it looks now:

Really clean job on the battery, congratulations. As for settings, I'm pretty sure you'll want more than 10A of busbar current for the main three modes, unless it will only ride in sport

 

[John555]

True. More sound better.
I'm start with 10, because in previous software (i suppose so) i exact that place were "Regenerative Current A".
Now they replace it with "Busbar Current"
This confused me a bit, because in the case of both of these variables, extreme values can either damage the bms,
Or, as you mentioned, the controller will only reach maximum in sport mode.

That thing was a dog with the 50cc at 155kg, it’ll be better electric for sure but still too heavy. Those cells are rated 5c continuous and nearly 10c peak for 10s at 50% soc; I’m sure you could push far more for less time. Thing is with only 40ah and the juice to make that boat fun, you won’t be seeing an hour runtime. More like 15-20 minutes until lvc.

Slowly moving forward.
I put the vehicle together enough to be able to do some test drives

In the meantime I fixed some mounting points and lifted the engine slightly due to the chain tension caused by the suspension work
Chain sprockets: Front - 14T, Rear - 38T
Tires 22x7 R10 (520 mm diameter)
Motor is factory set to 7000 RPM

Max reached speed 83 km/h - 51 Mph
There is enough torque to burn tires on dry asphalt.
Honestly, the rear tires can't handle all the power - I will change them to something wider and more off-road in the future

I am also thinking about changing the rear sprocket to 45T to slow the vehicle down to 60 km/h
It's a fairly simple machine with not very advanced suspension
driving at speeds of around 80 km/h on unpaved roads is bit risky

I have one small problem with the controller.
When I move slowly
This problem occurs mostly when I am going downhill, when the motor is pushed
Driver gets an error and doesn't let you continue driving
Restarting solves the problem

Your work is very nice sir, thank you for sharing it. That looks so fun to roast your your tires off with! I use that same throttle/switch setup on my big scooters and really like it. Would love to see some action video of what kind of acceleration you are getting. Also what kind of run time and and charging times you end up with. I keep dreaming of trying this type vehicle with two hub motors in the front wheels for 4wd. I think that could be very powerful and an awesome climbing machine. Just sayin. Thanks again.

Nice E-ATV!
Have fun with it when it is riding the way you want.
