1. Some of the VX-1 requaires grinding a weld in battery compartment to accomodate new battery. After removing old battery cover the motocontroller using plastic foil and masking tape. Remove the excess of the weld by angle grinder to be flat with frame strud. When finish vacuum the battery compartment.

3. Install front pack in the vehicle (using lift tool). Push it forward to the end of compartment

4. Install rear pack in the vehicle.

5. Connect negative power cable (oryginal) to the rear pack - pass it though the hole in the rear wall of the battery and secure with provided M6 bolt (make sure the ring of the battery harness is installed as well)



6. Install the flat cable between the battery pack front and rear using supplied M6 bolts with conical head




7. Install the battery to BMS patch (front and rear)

8. Using inrush current limiter (or 110V 35W bulb or 100kOhm 5W resistor) connected between battery positive terminal and positive cable - charge the MC capacitors - before connecting positive cable.

9. With inrush limiter still connected install positive cable. Disconnect inrush limiter. Tie the positive cable using supplied zip tie holders.



10. Place the BMS box on top of rear battery pack. There is a rivet on the lid of rear pack matching a hole in BMS housing to align. BMS box has double side adhesive tape on bottom..
