Look what I have here my friends!
Now it is just a usual gasoline motorized sled.
But now we are going to make it much more interesting, lets go!
Hi guys as usually its me just a voice over and you are watching review machines!
Today we’ll make quite an exciting experiment!
So we’ve got pretty standard gasoline motorized sled.
It is simple but durable machine, we chose it as a base for our project for its reliability.
By the way thanx our friend Ilya who gave us this new motordog!
As you may guess we are going to convert this gasoline machine into electric drive!
So its no matter what the engine is here, more important that there is a good reliable
frame and chAssis.
You may ask for what purpose we are going to convert it?
Actually we expect from this project quite an impressive practical results.
Well we have a lot of things to do now, so lets begin!
Now we are in the E-Max company.
These guys are ones of the best in the field of electric transport!
Thanx the founder of the company Maxim for great help in this project!
By the way you may have seen already some machines made by these guys.
Their job actually is to convert usual machines into electric drive.
As we can see our sled is being modified already!
The work is in the full swing!
First of all we removed the engine and CVT, we don’t need them anymore.
All we need its such a platform.
We installed a proper electric motor here.
Then there is a controller next to it.
And now we are assembling the battery.
An important feature – the battery will be equipped with heating system for efficient
work in frost.
We use one of the best lithium elements for the battery so we expect an impressive performance
from our sled.
And now it is actually the very first test of the machine with installed electric drive.
It works!
We see our sled transforming into a real electric beast now!
And finally it is time for the first field tests!
We’ve done so many things that were left behind the camera.
And now our project is ready to show us its performance after the conversion.
Also we’ve got one more gasoline sled of the same model to compare them with each other.
And now lets look in details what we finally made here.
Firstly we see here quite a big electric motor with maximum power up to 20 kwt.
Then there is a huge lithium battery 72 volts power and 120 Ah capacity and certainly a
proper controller.
All the components, the engine, the battery and the controller are absolutely waterproof.
Take a notice how much free space we have in comparison with the gasoline version.
Now it can be used for additional boxes for cargos for example.
Also we installed the inverter to 220 volts so we can plug in any electric device we want.
The steering is the simplest.
There is a throttle at the right.
Then the power button, and reverse mode button.
And this is a charger, it takes about 5 hours to charge it from zero to 100%.
In fact the result should be quite powerful.
That is why we took a special version of the motorsled for the comparison.
It is also modified gasoline machine with the most powerful engine this transmission
can sustain.
Its power is 25 hp!
It is really too much for the motorsled!
But in this way we’ll get a more exciting comparison.
And I think it is high time to start it.
But before that I should mention that we have only 80% of battery now, unfortunaly we didn’t
have enough time today to charge it completely.
First of all we start our machines.
And the difference is obvious even now.
Usually it takes some efforts to start the gasoline machine, thanks that we have an electric
starter here.
And all we need to start the electric one is just to press the button and its ready
to go!
Now I’d like to mention about the reverse mode.
Sometimes it is also available on gasoline models, but it is quite an expensive feature,
cause it requires to install a gearbox.
And all we need to do on the electric model it is again just to press the button!
One of the most significant differences between two models it is a noise.
Its common knowledge how irritating the petrol engine noise can be.
And undoubtedly the electric sled its much more better.
Its almost noiseless!
All we can hear it is just a sound of the transmission.
Well and now lets have a ride in the field to find out how it actually goes.
In fact these machines are designed to be used in winter most of all.
But unfortunately we still don’t have any snow.
Besides our model actually is able to move on the ground cause it has all seasonal chassis.
As to the first impressions…well it is an awesome machine!
If you tried once to ride a powerful electric vehicle you know how it feels!
Smooth and so impressive power in all the modes.
Instantaneous reaction on the throttle!
It provides so much emotions when riding it!
Especially this thing impresses when you push a throttle a little bit more!
It accelerates like hell, tearing the ground under its track!
Lets do the drug racing now!
We are going to find out who accelerates faster!
Lets go!
Despite the gasoline opponent it is also a very powerful model, our electric beast overtakes
it!
But then we found out that was not full throttle on the electric machine.
So lets try it again!
Well the difference is significant now!
We can see the electric sled accelerates much faster!
Now we will try to check the maximum speed with gps tracker mounted on the frame.
And the result is almost 50 km.h!
And as a matter of fact its pretty fast for this kind of machines!
And we should take into account that the speed will be even more on snow.
In fact the speed is not the most important feature here.
More relevant characteristic it’s torque.
And as we can see the torque is perfect even with the minimal speed.
And its high time for tug of war.
It is a perfect test to compare the torque of the both versions.
Well this time its an obvious victory of the gasoline sled!
The matter is the electric model has a special overload defense that switches off the motor
if the load is too much.
After such an intensive ride we got quite hungry.
It is time to have a snack!
Huge thanx we installed an inverter here and now we can heat our sandwiches in the microwave
oven!
Well it works!
Just few minutes and we are enjoying our hot sandwiches on the fresh air in a beautiful
place with our good friends.
What can be better guys?
Except the oven we can use any devices like electric tools for example that can be very
useful in the long trip.
Well what conclusion can we make out of these results?
To my mind the idea of the project is brilliant!
Electric sled is much more simple and comfortable for use.
Its much more silent, faster, simple for handling, needs no fuel and oil, no any exhaust, so
little maintenance required, waterproof.
The flip side is only one to my mind – it is the limited range.
As to the price.
We used in out conversion hi end elements, so they are quite expensive.
This very model with all the same elements and specs will cost about 4500 thousand dollars.
As to the range we are going to make a single test for it.
Today we consumed only about half of the battery for all day of active riding.
Guys if you want us to make a range test please post your comments, so we would know that
this project is interesting for you.
Thanks for watching guys, please consider subscribing the channel if you liked this

Stay with us, it will be many more interesting materials here, good bye!
