7S2P 25.9V 5800mAh 18650 Battery Pack FAQs
Does the battery pack include over-temperature protection?
Yes. The integrated PCB/BMS provides comprehensive temperature protection. Charging and discharging automatically stop when temperatures exceed safe thresholds to prevent thermal risks and extend battery life.
Can the battery size or configuration be customized for my device's limited space?
Absolutely. CM Batteries can redesign the internal layout (e.g., 7S1P, 6S2P) and adjust cell orientation, wiring, or housing structure to ensure an optimal fit within your device’s mechanical constraints.
How does this 18650 battery pack perform under rigid conditions?
The pack is engineered with a robust internal structure, reinforced cell holders, and a securely mounted PCB. It maintains stable output even under continuous vibration, impact shock, and sudden directional changes.
Is the battery certified for international transportation?
As a custom-built solution, this battery pack is designed and tested to be compliant with UN38.3 safety requirements. However, formal certification is not included by default. Should your logistics require official UN38.3 documentation, we can facilitate the certification process. Please note that the related testing fees and administrative charges will be incurred separately.
