Petrol Bolan Electric Bolan

Breakeven: 23.3 months. Petrol starts low but grows every month. Electric starts with the conversion kit cost, then rises slowly because charging is cheaper.

EV Engineer's Note

This is our strongest commercial business case — the Bolan's high daily mileage in delivery and school-van use means the conversion typically pays for itself faster than any private car in our lineup. We reinforce the rear leaf spring mounts to handle the added battery mass under full payload. One honest limitation: payload capacity drops by roughly 80kg versus stock, which matters if you're routinely running at maximum load. — EV Square Conversion Team

Installation timeline

7–9 working days from drop-off to delivery, Long Range kit with commercial reinforcement.

Day 1–2

Strip-down & load-bay assessment

Engine, fuel tank, exhaust removed. Cargo/load floor inspected for battery mounting and reinforcement points.

Day 3–4

Motor & controller fitting

PMSM motor mounted to existing gearbox interface. Controller wired in, IP67 connectors sealed and vibration-tested.

Day 5–6

Battery pack & reinforcement

LiFePO₄ pack secured under load floor with reinforced mounts. Smart BMS wired with active cell balancing leads.

Day 7

Calibration & loaded bench test

Drive modes calibrated under simulated payload. Regenerative braking tuned. Full diagnostic run on stand.

Day 8–9

Loaded road test & handover

Road test under typical commercial load, suspension re-verified, handover with warranty documentation.
