Ensure the security, stability, and reliable power connection of your Wallke eBike with our replacement battery head. This component is specifically engineered for Wallke eBike models only and plays a critical role in locking the battery securely to the frame while maintaining stable electrical contact during riding, even on rough terrain.

Wallke eBikes come in multiple versions, and battery heads are categorized based on different structural and electrical configurations:

• Large head / Small head — matched according to frame size and battery housing design
• Up discharge / Down discharge — defined by cable outlet direction for proper wiring alignment

Because different model years and configurations may use different battery head designs, it is essential to provide your frame serial number and battery type when placing an order. This ensures accurate verification and guarantees you receive a fully compatible replacement that fits and functions correctly with your eBike system.

When should you replace the battery head?

• Lost Keys: For security reasons, duplicate keys are not available. If your keys are lost, replacing the entire battery head is required to restore access and secure battery locking.
• Damaged Lock or Mechanism: If the locking system is worn, broken, or no longer secures the battery properly, a replacement is necessary to ensure safe riding and prevent battery instability.
• Poor Electrical Contact: If you experience intermittent power loss or unstable connection, replacing the battery head may help restore reliable performance.

What’s included:

• 1 × Battery head unit (with integrated lock system)
• 2 × Matching keys for secure operation

Installation & Usage Notes:

• Ensure correct alignment during installation to avoid connector damage
• Do not force the battery into the mount if resistance is felt
• Regularly check the locking mechanism to ensure safe battery retention

Important Notice: To ensure accurate matching and prevent incorrect orders, please provide your order number, frame serial number, and battery type when purchasing. This helps us verify compatibility and ensures you receive the correct battery head for your specific Wallke eBike model.

If you are unsure which version you need, feel free to contact our support team before ordering. We will help you confirm compatibility and ensure a safe, secure, and perfect fit for your eBike.
