FAQs About 7S 21700 Li-ion Battery Packs
Can I use a 7s BMS that is intended for 18650 batteries with 21700 batteries instead?
Yes, electrically it works, but make sure the BMS current rate is right for the job and that it doesn’t physically have to fit 18650 holders. Always check the BMS document or the specs from the manufacturer before you use it.
For long range battery packs, do you prefer using 18650 or 21700 li-ion cells?
For long-range battery packs, 21700 is the better choice due to:
- Higher energy per cell
- Better performance
- Improved efficiency
- Easier pack optimization
My device needs to operate in high or low temperatures, can you customize it?
Of course, we can customize the battery pack based on your device’s specific requirements, including temperature tolerance, size, discharge rate, and more.
Do you offer 7S battery pack certification services?
CM Batteries can help with certifications like UN38.3, IEC62133, and others, and offer testing reports and MSDS.
