LiPo Battery 402933
The HHS 402933 is a small lithium polymer cell in the HHS Energy polymer range, with a stated capacity of 320 mAh at 3.7V. Its stated size is 4.0 mm thick, 29 mm wide and 35 mm long, including the protection circuit module. It is larger than the 401030 cell and suits devices that need more runtime in a still-compact pouch: small consumer electronics, handheld devices, compact instruments and portable equipment.
The cell is supplied with a protection circuit module and can be supplied with leads or a connector to match the device. Protection boards stated for the polymer range are DW01 plus 8205 and G3J plus 8205 combinations. The stated cycle life is 600 cycles or more, and the lead time is 7 days. Custom polymer work covers custom voltages from 3.7V upward, a wide capacity range, custom sizes and shapes, and battery management systems from 10A to 100A and above, so a device that needs something between the listed sizes can be quoted as a custom cell.

Notes on This Specification
The specification above transcribes the stated figures for the 402933 cell only. The 402933 is distinct from the 401030 cell: the two differ in capacity, 320 mAh against 90 mAh, and in width and length, and they are presented as separate products with separate specifications.

Design Notes for Device Makers
Designing a device around the 402933 cell starts with the footprint: 29 mm wide and 35 mm long, with a thickness of 4.0 mm including the protection circuit module. That footprint suits handheld devices and compact instruments where a wider pouch fits better than a narrow one. The cell's 320 mAh capacity is more than three times the 401030 cell's 90 mAh, so it suits devices with higher daily energy use or longer intervals between charges. A device drawing 10 mA on average runs for well over a day on a charge, and a device with intermittent use runs for much longer.
As with other polymer cells, the device's charging circuit must match lithium polymer charging at 3.7V nominal, with the protection board as a safety backup rather than the primary control. The compartment should protect the pouch from sharp edges, pressure and bending, and the lead or connector routing should avoid strain on the cell tabs. Confirm the lead or connector type, the quantity and the 7 day lead time with the quote. If the device needs a capacity between the listed cells, custom polymer work can quote a size between them.
