3.7V 1500mAh LiPo Battery

HSS Energy 3.7V 1500mAh LiPo Battery is for compact electronics needing more energy than smaller 500mAh cells. The sample uses a protection PCB and 2-wire connector; current, plug, polarity and finished dimensions are confirmed for the target device. This makes it suitable for portable products that need longer operating time but still require a relatively thin rechargeable pouch battery. The current sample already demonstrates a protection board, red-black leads and a 2-pin connector, while the final connector housing, polarity, lead length and current limits remain project-specific. A device drawing or original battery sample gives HSS the best basis for matching those details.

Electrical Identity, Format & Pack Envelope

803450 Format

An 803450 LiPo battery uses an approximately 8 × 34 × 50 mm nominal cell format; PCM, tape, leads and connector can extend the finished pack length. That code describes the pouch-cell body rather than the complete finished battery. PCM, tape, tabs, wires and the connector can extend the final length or thickness, which matters in tightly packaged electronics. For production release, HSS should record the final pack envelope separately from the nominal cell code so the customer can check enclosure fit and assembly clearance accurately.

Why Choose 1500mAh? Energy vs. Size Tradeoff

A 3.7V 1500mAh LiPo battery stores 5.55Wh—three times the nominal energy of a 500mAh / 1.85Wh pack—but needs a larger battery cavity. The additional energy can extend the interval between charges in suitable products, but it also requires a larger battery cavity and may change device mass or balance. customers should therefore treat the upgrade as an energy-versus-space tradeoff rather than assuming the larger capacity is always better. The real benefit depends on average load, peak current, duty cycle and how often the product is expected to recharge.

HSS size-and-energy comparison: 602535 500mAh / 1.85Wh versus 803450 1500mAh / 5.55Wh. Three times nominal energy does not guarantee three times device runtime. This comparison is useful for product planning because it shows why two batteries on the same 3.7V architecture can serve very different devices. The 500mAh format favors smaller cavities and lower mass, while the 1500mAh format provides more energy reserve when the product can accept additional thickness and footprint. HSS can use the device runtime target and cavity drawing to help determine which direction is more appropriate.

For the 803450 3.7V 1500mAh LiPo Battery, verify runtime and peak load, then confirm the 8mm-class pouch plus PCM/connector envelope fits the device. The battery should have enough continuous and peak-current margin for the real product, not only enough nominal energy. Motors, heaters, wireless transmitters and actuators can create short high-current events that must be checked against the selected cell and PCM. Once the electrical profile is acceptable, the finished 8mm-class pouch assembly, wiring and connector can be validated against the mechanical design.

Protection, Connector & OEM Integration

A 1500mAh LiPo battery with PCM adds protection, but charge, discharge and over-current limits depend on the selected cell and board. The board does not make every configuration electrically identical because charge, discharge and over-current limits depend on the selected cell and PCM design. HSS therefore needs the device's steady and peak load together with the charging profile before finalizing the protection configuration. This is especially important in portable devices that combine wireless communication with motors, heaters or displays.

An 803450 battery with connector must match housing, pitch, polarity, wire and lead length from the device drawing or original battery. Connector compatibility should be confirmed from the device PCB, connector drawing or original battery rather than from appearance alone. Wire gauge and lead length also affect routing and voltage drop, while the wire exit can change the finished pack envelope. Freezing these details in the sample drawing helps OEM customers keep the bulk-production assembly consistent with the approved prototype.

Application Fit: Where 803450 Adds Value

An 803450 lithium polymer battery fits compact devices needing more energy than smaller wearable-class cells while staying on a 1S 3.7V architecture. Its 5.55Wh energy class can be valuable in beauty devices, trackers, portable medical products, handheld terminals and monitoring equipment where longer use between charges improves the user experience. However, application fit still depends on the real load profile, heat generation, charging frequency and battery cavity. HSS therefore positions the 803450 as a higher-energy compact platform rather than a universal battery for every 3.7V device.

Application selection should start from real power pattern, peak load, charging frequency and available battery cavity. A product with long standby and short radio bursts has a different battery requirement from a device that drives a motor or heater for several minutes. By separating average energy demand from peak-current demand, customers can avoid oversizing the battery for runtime while overlooking the current capability that actually determines performance.

SEND YOUR DEVICE BATTERY REQUIREMENTS

For an 803450 3.7V 1500mAh LiPo Battery fit review, send HSS Energy the load, runtime, charging profile, cavity, connector, polarity and lead length. If possible, also send the original battery or device-side connector photo, target sample quantity and expected production volume. This gives HSS a stronger basis for matching the electrical configuration, finished pack envelope and commercial production requirements before the quotation is finalized.
