Yes, absolutely. We can design and build battery packs tailored for challenging conditions. We offer solutions using 18650 cells rated for wide operating temperatures (e.g., discharge from -40℃ up to +85℃ discharge with specific cell types), and our pack designs can incorporate features for waterproofing, shock resistance, and intrinsic safety (explosion protection) as required by your application.

Yes, we can facilitate and provide these certification services for your battery packs. The typical estimated lead times are:

• UN38.3: Approx. 2 weeks
• CE: Approx. 1 week
• UL:  Approx. 5 weeks(Please note these are estimates and can vary based on testing queues and specific requirements.)

Yes, BMS customization is one of our key services. We can design or modify the BMS functionality, communication protocols (like SMBus, CANbus, etc.), and protection parameters to precisely match the unique requirements of your application and ensure optimal performance and safety for your custom battery pack.

An 18650 battery pack combines multiple individual 18650 lithium-ion cells (18mm x 65mm) wired together to achieve higher voltage, capacity, or both. Cells are connected in series (S) for voltage increase, parallel (P) for capacity increase, or a combination (e.g., 3S2P).

The lifespan of an 18650 battery pack depends on its quality, chemistry, usage (charge/discharge cycles, depth of discharge), and operating conditions. With a good BMS and proper care, a pack can last hundreds to over a thousand cycles, potentially 3-5 years or more, before significant capacity degradation. Avoiding full discharge and extreme temperatures extends its life.

For long-term storage, charge the 18650 battery pack to its "storage voltage" (typically 3.7V to 3.85V per cell), not full or empty. Store it in a cool, dry place, away from direct sunlight, extreme temperatures, and flammable materials. Avoid storing fully charged or fully discharged for extended periods, as this can degrade the cells.
