🔋 Standard Charging: Only use chargers specifically designed for LiFePO4/LTO chemistry. Do not exceed the maximum charge voltage and current specified in the datasheet.
🌡️ Temperature Range: Do not charge the battery in temperatures below 0°C (unless specified) or above 45°C. Discharge temperature must remain within -20°C to 60°C.
⚡ Short Circuit Prevention: Strictly avoid direct connection between the positive and negative terminals with any metal objects. Ensure terminals are insulated during assembly.
🛡️ BMS Requirement: These are raw cells. A high-quality Battery Management System (BMS) must be installed for over-charge, over-discharge, and thermal protection.
⚠️ Physical Protection: Do not puncture, crush, or drop the cells. If cells show leakage or deformation, stop using them immediately and contact DLCPO Support.
💡 A: DLCPO Power is a professional, technology-driven distributor specialized in high-grade lithium cells. We are an authorized gateway to industry-leading brands including CALB, EVE, REPT, and GOTION. Unlike standard trading firms, we provide engineering-grade quality control, ensuring every cell is 100% tested and precision-matched for voltage and internal resistance before dispatch.
💡 A: This is a deliberate strategic choice to protect your battery lifecycle. Batteries stored in overseas warehouses for months suffer from capacity degradation and voltage imbalance. At DLCPO, we operate on a “Zero Aged Stock” model. Every order is fulfilled via made-to-order production or allocated from the absolute latest factory batches. This guarantees you receive 100% fresh Grade A cells with peak chemical activity and perfectly matched performance.
💡 A: Yes, we provide full technical customization to simplify your assembly. Based on your project requirements, we can professionally process each batch by laser-welding specific terminals (such as standard M6 threaded studs) and providing perfectly matched connecting busbars. Our goal is to ensure your cells arrive “plug-and-play” ready for immediate pack integration.
💡 A: We offer a streamlined B2B purchasing experience:
Consultation: Confirming cell models and technical specs via dlcpo@dlcpo.com.
Flexible Terms: We support EXW, FOB, and DDP shipping (available for most global regions, handling all customs and import taxes).
Fresh Allocation: Arranging the latest factory batch production.
Testing & Logistics: 100% matching test followed by UN38.3 compliant dangerous goods packaging and global dispatch.
💡 A: At DLCPO, we firmly believe that receiving payment and delivering goods is not the end of a transaction, but the true beginning of our service value. Our technical team provides continuous post-delivery support, including warranty assistance and BMS configuration guidance. We don’t just sell cells; we ensure your energy systems perform optimally for their entire service life.
