Lipo Battery Cell Capacity Fast Calculator
Enter basic cell dimensions to estimate Capacity (mAh) and Energy (Wh). Results are approximate.
Assumptions (editable in code): volumetric energy density (approx.) — LCO(3.7V)≈600 Wh/L, LMO(3.7V)≈500 Wh/L, NCM(3.6V)≈620 Wh/L, LFP(3.2V)≈350 Wh/L, LCO(3.8V)≈650 Wh/L, LCO(3.85V)≈680 Wh/L. C-rate derating (usable energy): 1C=0.98, 3C=0.94, 5C=0.92, 10C=0.88, 20C=0.82. For accurate design, please validate with cell vendor datasheets and lab tests.
1. Can Jetray customize lithium battery packs for my specific application?
Yes. We tailor battery packs to your voltage, capacity, size, shape, discharge rate, and communication needs (CAN, SMBus, etc.), for sectors like EVs, ESS, medical, and more.
2. What is the typical MOQ for custom lithium battery packs?
Our minimum order quantity is 100 pcs for prototypes. For mass production, MOQ starts at 500–3000 units, depending on your requirements.
3. How long does it take to develop a custom battery pack?
Prototyping usually takes 4–6 weeks. We offer expedited services for urgent projects.
4. What certifications do Jetray’s batteries support?
We provide batteries compliant with UN38.3, IEC62133, CE, RoHS, and MSDS. Additional certifications can be arranged upon request.
5. Can Jetray integrate a smart BMS into my battery pack?
Absolutely. We design and embed BMS with functions like overcharge protection, temperature monitoring, and real-time communication (CAN/RS485).
