3.8V 5600mAh LiPo Battery Pack FAQs
Can the battery size be adjusted to fit a very tight enclosure?
Yes. Dimensional customization is a core part of CMB’s LiPo battery design process. Thickness, length, and tab orientation can be optimized based on the device’s internal structure.
How do you ensure stable performance under high current conditions?
We start with low internal resistance cell selection and then optimize current paths and structural design. This helps keep voltage output stable and heat generation under control during operation.
Can the battery be designed for different discharge patterns?
Yes. Some applications need continuous high current, while others only need short bursts. We can adjust discharge limits, cut-off voltage settings, and internal design so the battery matches the real load profile instead of just nominal values.
