3.8V 1200mAh LiPo Battery Pack FAQs
Why not just use a standard 1200mAh battery from the market?
Standard batteries often look similar on paper, but in real products they may not match the actual current load, charging behavior, or available space.
Customization allows the battery to be designed around how the device is really used, which usually results in better stability and longer service life.
Does increasing capacity create more thermal risk?
It can, especially if charge and discharge currents are not well controlled.
As capacity increases, heat management becomes more important.
We typically optimize internal resistance, charging current, and pouch structure to keep temperatures within a safe range during normal operation.
Can charge and discharge currents be adjusted for our device?
Yes. Both standard and maximum currents can be adjusted based on the power profile of the device and the charger design. This helps prevent unnecessary stress on the battery and improves long-term reliability.
What certifications or compliance support are available?
CMB supports battery designs aligned with UN38.3, MSDS, and relevant safety standards. Certification support can be adjusted based on project market and regulatory requirements. This helps shorten approval timelines for automotive electronics.
