Supplier Selection Guide

To help global purchasers select reliable power lithium battery suppliers, we provide a professional step-by-step guide:

1. Clarify Core Requirements
Define application scenarios (electric vehicles, energy storage), performance needs (cycle life, energy density), budget and target market compliance standards before selecting suppliers.

2. Verify Technical Capabilities & Compliance
Check suppliers’ independent R&D capacity, core patents and product testing systems; confirm products have international certifications such as UL, CE and FCC; request third-party test reports to validate performance.

3. Evaluate Product Reliability & Cases
Review long-term reliability data (cycle life, temperature resistance); verify reference cases in your industry; request samples for on-site testing before large-scale procurement.

4. Assess Global Support Services
Confirm localized service networks, warranty terms (1-3 years for Shenzhen Kangkedi Intelligent Technology Co., Ltd.) and after-sales technical support capabilities; check if suppliers offer customized services to meet special project needs.

5. Compare Total Cost of Ownership
Evaluate not just unit price but also product lifespan, maintenance costs and supply stability to select cost-effective partners that reduce long-term operational costs.
