H01N2-D is the standard for motorsport battery and high-current power wiring — Class 6 extra-flexible stranded copper with a chloroprene (neoprene) rubber sheath. The fine copper stranding gives it a suppleness that rigid PVC battery cable cannot match, which matters when routing through firewalls, around roll cage tubes, and through tight conduit. The neoprene sheath resists oil, petrol, hydraulic fluid, battery acid, and ozone, and remains flexible at low temperatures.

Sizing Guide
| Cross-section | Typical application |
|---|---|
| 16 mm² | Battery to cut-off relay or kill switch; chassis ground strap up to ~150 A peak |
| 25 mm² | Battery to PDM main feed; high-power builds; longer runs where voltage drop must be minimised |
As a general rule: for cable runs up to approximately 1.5 m, 16 mm² is sufficient for most single-ECU club race cars. Use 25 mm² for runs longer than 1.5 m, cars with multiple ECUs or EPS, or any installation where sustained current exceeds 120 A.
Typical Motorsport Applications
- Battery positive lead to main cut-off relay or kill switch
- Main relay output to PDM or fuse box
- Chassis ground strap — battery negative to bodywork or roll cage
- Supplementary earth returns from engine block or gearbox
- Power supply to auxiliary battery or capacitor bank
