 2.928,00 inc.VAT |  2.400,00 ex.VAT

The MAHLE Letrika AC conversion kit ASV 7102  is designed for those who want to build their own electric car and collect experiences with electric power driven vehicles. The kit enables self-builders to convert a car with an internal combustion engine to a purely electric car. The kit is suitable for low power applications such as quadricycles in the L6e and L7e categories and small cars in the M1 category.

After conversion, the vehicle should be homologated to meet the specific country’s legislation if the vehicle is intended to be used on public roads. It is the responsibility of the self-builder to be understand what actions are required before commencing work.

Conversion kit includes:

  • Controller unit 11. 258.460 AEK1350 H48V 400A T5
  • AC induction motor 11.217.136 AMV7122 20V 15kW
  • Harness
