From Requirement to Delivery
-- A Clear 6-Step Process
We guide every project from initial inquiry through engineering, sample validation, and mass production to ensure a smooth, on-time delivery.
Requirement Analysis
Share your device specs: voltage, current, size, weight, environment, and application. Our engineers evaluate your requirements within 24 hours.
Solution Design
We propose a tailored battery solution: cell selection, S×P configuration, BMS spec, connector, housing, and estimated cost. You review and approve.
Sample Production
We manufacture 1-5 prototype samples following the approved design. Each sample undergoes full electrical and safety testing before shipping.
Sample Validation
You test the sample in your device. We support any required spec adjustments, connector changes, or BMS parameter tuning until the design is confirmed.
Mass Production
Once the design is approved, we schedule production on our automated or manual lines. Strict 11-step QC is applied to every batch.
Export & Delivery
We handle export packaging, UN38.3 documentation, MSDS, and coordinate international shipping to your warehouse or end customer location.
