Components overview
We offer components for self-assembly of light electric vehicles. If you are an electric vehicle development company, we can become your OEM partner, which will save a lot of time and effort, thanks to a reduction in the cost of research, development, testing, and support of your own components. Using our line of solutions you get constant technical support and software updates.
Controllers
6F | 12F | 24F
A powerful ARM microprocessor provides precise and smooth control of the BLDC motor. The controller settings are widely configured — you can set parameters, power strokes of the gas throttle, fully customized to your needs. The controller achieves an efficiency of 98% due to the powerful MOS transistors and special PWM algorithms. Compact size allows you to install it in any suitable place on vehicles with different dimensions — from scooters to ATVs or golf carts.

Battery Management System (BMS) 16S | 24S
Battery Management System is a system for controlling the energy consumption of a battery. BMS protects each element in the batteries from discharging and recharging. An adaptive battery balancing algorithm accelerates the time of voltage equalization between its elements. For cold weather, the BMS provides for heating the battery. The wattmeter calculates how much energy was used and shows the statistics of energy consumption. The user is able to see the state of charge of the battery and the error diagnosis on the information screen.

In developing. Preorder available.
