Q2: What customization services do you offer?
A: We provide one-stop customization services for polymer lithium-ion batteries, including:
• Size & Shape (custom length, width, thickness, irregular/curved/ultra-thin designs);
• Performance (nominal voltage, capacity, discharge rate, high/low temperature adaptation);
• Integration (PCB/BMS protection board, NTC thermistor, wires & connectors);
• OEM/ODM services (custom logo, packaging, battery packs).
Q3: What information do I need to provide for custom batteries?
A: To provide you with accurate design solutions and quotes, please inform us of: the nominal voltage and capacity; size (L*W*T) or installation space; application scenario (e.g., smart wearables, IoT, medical devices); special requirements (e.g., fast charge, high discharge rate, low temperature resistance); and expected order quantity.
Q4: What is the lead time for samples and bulk orders?
A: For standard samples, it takes 3-5 working days; customized samples take 7-10 working days. For bulk orders, small orders (1000-5000 pieces) take 10-15 working days; medium orders (5000-20000 pieces) take 15-25 working days; and large orders (20000+ pieces) take 25-35 working days.
Q5: How do you ensure product quality?
A: We have a strict quality control system in place: raw material inspection (positive/negative electrode, electrolyte, diaphragm); production process monitoring (injection, encapsulation, formation); finished product testing (capacity, cycle life, safety, temperature performance); and 100% inspection before shipment.
