Frequently Asked Questions

The latest research says that EV production is more environmentally hostile than keeping your existing car and by converting your existing car you help the environment. But you also get a big money-saving as you can maintain your car very cheap as we have all spare parts at a much lower price than any other car manufacturer.


The electric vehicle controller is the electronics package that operates between the batteries and the motor to control the electric vehicle's speed and acceleration much like a carburetor does in a gasoline-powered vehicle.
Torque is the force you feel pushing you back in your seat on acceleration, while horsepower is the speed achieved at the end of that acceleration
In general terms Low Voltage = Poor efficiency and performance
The biggest difference is the type of current each motor turns into energy, alternating current in the case of AC motors, and direct current in the case of DC motors. AC motors are known for their increased power output and efficiency, while DC motors are prized for their speed control and output range. AC motors are available in single- or three-phase configurations, while DC motors are always single-phase.
Electric motors provide instant torque and have a very strong start but for the end speed, you also need more power measured in kW/hp.

50 km/h = 6kW
70 km/h = 10 kW
80 km/h = 13 kW
90 km/h = 16 kW
100 km/h = 20 kW
110 km/h = 24 kW
120 km/h = 29 kW

This calculation is for a 1000 kg car.
Note that like with combustion engines more kW will consume more kWh of battery.
NCM batteries are recommended only for sports cars where weight and space are a problem as they can provide more power with much lower space required and are 40% lighter. They are also known to possibly catch fire if damaged so they should be placed in a secure place. They burn fast like gasoline.

LiFePO4 batteries are recommended for all vehicle types as the safest and most long-lasting batteries with double cycles compared to ncm.
All our EV Conversion Kits can be charged at public charging stations with type 2 plug. Charging speed depends on the charger.

Example of a 10 kWh battery
2 kW charger = 5h
6 kW chargers = 2h
9.9 kW chargers = 1 h

The standard house has a total limit of 5.5 kW so that means that 2 - 4 kW chargers are the best for home usage.​
Range from 10° C to a high end of 43° C allows the battery to operate at peak performance while preserving its longevity and ability to function at the highest capacity for 6,000 cycles.

When allowing for 2,000 and 3,000 cycles, that range increases to 0° C up to 48° C.
We provide guarantees on all EV parts and since our systems are simple and separate in parts it's very easy and cheap to replace any part. It's even much cheaper than replacing parts on regular gasoline or diesel car.
You will find that having an electric car is very expensive for repairing but this is not our case as we can fix even battery issues.
All our battery packs are designed so we can have them easily repaired and to minimize the time and expenses.
Our goal is to keep in the business all local car mechanics and electricians for quick, easy, and cheap maintenance of your cars. To have that achieved we are providing the full specifications and documenting for all parts keeping it as simple as possible and educating everyone about fixing all parts to reduce waste.

We also provide installation instructions so anyone with simple tools can fix most issues.
We have several options for use with your existing car heating installations, one is electric water heating and the other is stronger webasto/diesel water heating for a longer range. Webasto diesel heating has a small tank from 3-10L which can be placed under the hood.
We recommend adding solar panels to your home (if possible) as that will drastically improve your electricity bills and you can drive your car for free or almost free.
Here is a simple example for Croatia/EU: home electricity cost per kWh is 0.12€ while industrial is 0.40€. Now let’s say that a small city EV car consumes 12kWh on 100 km.

That means that on house charing your expense will be 1.44€ for 100 km, while on the industrial it will be 4.80€.
However, taking into count that you have solar panels your cost for 100 km now becomes much lower or 0 depending on the solar system setup.

Don’t forget that you can install solar panels in many places even if you live in a building, like balconies, terraces, windows…
All you need is solar panels, a fuse box, and an on-grid inverter.

Yearly calculation for 15 000km
– House plug: 216€
– Industrial plug: 720€
You can replace or upgrade any part easily with our help and at very affordable prices. You can replace the motor with a more powerful one, you can replace the charger with a stronger one or you can even add more batteries for a longer range.

We will try to cover all these examples in our documentation so you know all possibilities and how much it would cost you.
We recommend that you convert your car when you have high mileage or you are scared when the car engine starts with strange sounds, smoke, or before a yearly oil and filter change.

You can also start even sooner if you calculate your fuel economy is better to do that now and if you want to help to save the environment.
Battery Pack charging speed depends on the chargers you select, it can be between 2 and 9.9kW.

Example of a 10 kWh battery
2 kW charger = 5h
6 kW chargers = 2h
9.9 kW chargers = 1 h

The standard house has a total limit of 5.5 kW so that means that 2 - 4 kW chargers are the best for home usage.
Our EV Conversion Kit is designed for your car gearbox and that means that the flywheel, clutch, and gearbox remain in the car.

You would drive the car in the same way as before using the gear changer.
If we have previously developed an EV kit for the same car model as you have then EV conversion can be done in a shorter time but usually, it takes 1-2 months.
