It’s simple! When you invite a friend to SOK Battery Europe, they get a discount on their first premium LiFePO4 battery, and you earn a cash reward once their purchase is successfully completed.

Your Friend: Receives a €20 discount coupon for their first order. You: Receive a €20 cashback reward sent straight to your PayPal.

To ensure a fair and secure community, the following rules apply: The program is strictly for first-time customers only. The referred friend's order must meet a minimum value of €199 (excluding shipping). Self-referrals (referring yourself using different emails/addresses) are strictly prohibited.

No. The €20 friend discount coupon is valid for single use and cannot be combined with other seasonal sales, promotional codes, or B2B dealer discounts.

Your €20 reward is processed after the referred order has been successfully delivered and passes our 30-day return window without cancellation or refund. All payouts are transferred securely via PayPal to your registered email address.

Once the 30-day return window clears, our team typically verifies and processes your PayPal transfer within 7–14 business days.

Not at all! There is no limit. Whether you share it with one friend or your entire RV, marine, and solar club, you will earn €20 for every single eligible successful referral.

If an order is cancelled, fully refunded, or returned during the trial period, the corresponding referral cashback will automatically be voided.

Please double-check that your registered PayPal email is active. If you need any assistance, our support team is always here to help at eve@sokbattery.com.
