When battery space is thin, flat or tightly integrated into the product, a cylindrical cell is not always the best fit. A 3.7V LiPo pouch battery gives more freedom in thickness, footprint and wire layout while keeping the battery lightweight.
HSS Energy supplies 3.7V LiPo Battery Packs for compact electronics, handheld devices, wearable products, smart accessories and other OEM applications. Typical project capacities range from approximately 200mAh to 5000mAh. Our 3.7V Lipo Battery Packs series includes products such as 3.7V 1500mAh LiPo Battery, 3.7V 500mAh LiPo Battery, and so on.

Send Your Battery Space and Runtime Requirements for a LiPo Pack Review Capacity / Runtime • Length • Width • Thickness • Current • Connector • Wire Length • Quantity |
· thin or flat battery compartments
· low product-weight targets
· custom length, width or thickness requirements
· fixed wire-exit or connector positions
· devices where cylindrical cells use the available space inefficiently
The common capacity range for this category is about 200mAh to 5000mAh. Higher capacity normally requires more area, thickness or both, so runtime has to be balanced against the actual battery cavity and total product weight.

For LiPo projects, dimensions often come first Maximum length, width and thickness are usually more useful than an Ah target alone when the device enclosure is already fixed. |
For OEM projects, HSS Energy can review the pouch-cell size, capacity, protection circuit, connector, wire length, polarity, wire-exit direction, insulation, labeling and final pack layout around the device.
· capacity and pouch-cell dimensions
· protection circuit / PCM
· connector type and polarity
· wire length and wire-exit direction
· insulation, wrapping and label
· prototype and repeat-production requirements
A 3.7V LiPo pack should be matched to the device charging circuit and load. Depending on the project, the protection circuit can be configured for overcharge, over-discharge, over-current and short-circuit protection. Charging voltage, charge current and polarity should be confirmed before the pack specification is released.
· 3.7V 500mAh LiPo Battery
· 3.7V 1500mAh LiPo Battery
These are selected examples rather than the full range. Other configurations within approximately 200mAh to 5000mAh can be developed according to the required runtime, current, dimensions and connector layout.

Better Starting Point When |
|
3.7V LiPo Battery Packs |
Thin profile, low weight or custom pouch dimensions are important. |
|
3.7V Cylindrical Lithium Battery Packs |
The device can accept cylindrical cells and a more standardized pack structure is preferred. |
Send the required capacity or runtime, maximum battery length / width / thickness, normal and peak current, connector type or photo, wire length and polarity, charging method and expected order quantity.
|
Fastest way to start A device drawing or battery-compartment dimensions are especially useful because LiPo projects are often developed around available space. |
What capacity range is common?
Typical HSS Energy 3.7V LiPo projects range from approximately 200mAh to 5000mAh.
Can battery dimensions be customized?
Yes. Length, width and thickness can be reviewed around the device, subject to the available pouch-cell options and project requirements.
Can the connector and wire be customized?
Yes. Connector type, wire length, polarity and wire-exit direction can be matched to the device.
How is this different from 3.7V Lithium Battery Packs?
This category focuses on soft-pouch LiPo batteries for thin and space-constrained products, while the other 3.7V category is oriented more toward cylindrical-cell pack structures.
Can samples be made before production?
Yes. Prototype samples can be prepared for dimensional, charging and device-fit validation before bulk production.
