BMW i3 Battery Cable Clamps: Your Complete Guide to Correct Part Numbers & Replacement
Struggling to Find the Right Cable Clamps for Your BMW i3 Battery Replacement?
If you’re a BMW i3 owner considering a battery upgrade or replacement, you’ve probably encountered the frustrating reality that finding the correct cable clamps can be as challenging as finding the right battery itself. Many DIYers and repair shops waste hours trying to match the right part numbers, only to discover they’ve purchased incompatible components that compromise safety and performance.
Understanding BMW i3 Battery Cable Clamps: More Than Just Connectors
Battery cable clamps are the critical electrical connection points between your BMW i3’s battery pack and the vehicle’s power management system. Unlike ordinary connectors, these specialized clamps must meet strict OEM specifications to ensure:
- Proper current flow without overheating
- Secure mechanical attachment that withstands vehicle vibrations
- Compatibility with the BMW i3’s battery management system (BMS)
- Long-term reliability in varying temperature conditions
The Critical Part Numbers You Need to Know
While BMW doesn’t publicly list all cable clamp part numbers for service purposes, here are the key identifiers to look for when purchasing replacement clamps for your BMW i3:
For 2014-2016 BMW i3 (Rex)
- Main Power Cable Clamps: 002 28 1 000 370 (often labeled as “Battery Positive/Negative Terminals”)
- Auxiliary Connection Clamps: 002 28 1 000 371
For 2017-2020 BMW i3 (Standard Range)
- Main Power Cable Clamps: 002 28 1 000 372
- Battery Management System (BMS) Clamps: 002 28 1 000 373
Important Note: These part numbers are for reference only. BMW frequently updates components, so always verify with your vehicle’s VIN before purchasing.
Why Using the Correct Cable Clamps Matters More Than You Think

- Voltage drops during high-power demands
