Application for 3.7V 300mAh lithium polymer battery pack
This 3.7V 300mAh lithium polymer battery pack is suitable for low-power IoT sensor modules, wireless meter devices, compact data loggers, handheld monitoring instruments, smart lock backup modules, small security electronics and custom control assemblies where a thin rechargeable pack with wires, NTC and a connector is required. The LP592131P format gives designers a compact pouch-cell footprint while the integrated protection circuit and specified charging, discharging and temperature limits help simplify pack integration. VTCBATT can adapt the battery for different applications by matching connector type, adjusting wire length, configuring NTC requirements, designing the protection circuit, adding customer labels, supporting sample testing and arranging factory-direct battery wholesale or batch production for distributors, brand owners and OEM device manufacturers.
80°C High Temperature Cycle Test Report Summary
A concise article based on the Excel report 80 celsius degree test report.xls.
This high temperature cycle test evaluates the stability of a 300mAh lithium polymer battery sample under an 80°C operating environment. According to the Excel report, the recorded model is LP502035P-300mAh, the test quantity is four pieces, and the test period is seven days. The procedure was designed to simulate repeated
exposure to elevated temperature while monitoring discharge time and thickness change, two practical indicators for battery endurance and dimensional stability.
During each cycle, the battery was charged at 0.2C to 4.2V, then held at constant voltage until the current decreased to 0.01C. After a 10-minute rest, resistance, voltage, and thickness were recorded. The samples were then placed in a high temperature cabinet. Temperature increased from room temperature to 80°C at a rate of
5°C ±2°C per minute. After reaching 80°C, the samples were held for two hours and discharged at 0.2C for six hours. This process was repeated for seven cycles.
The available data for samples 6 and 7 shows stable discharge performance across the test. Sample 6 recorded an average discharge time of about 379.2 minutes, while sample 7 averaged about 377.7 minutes. Final cycle discharge times remained close to six hours, at 373.3 minutes and 369.7 minutes respectively. Thickness
increased moderately after repeated heat exposure, with sample 6 rising from 5.41mm to 5.87mm and sample 7 rising from 5.49mm to 5.894mm. Overall, the results indicate that the tested cells maintained usable discharge duration after seven cycles at 80°C, while showing measurable but controlled swelling under high temperature stress. For customers selecting compact rechargeable cells for warm environments, this type of report provides useful evidence beyond standard room-temperature capacity data. It helps engineers compare thermal endurance, packaging tolerance, and long-duration discharge consistency before moving into device-level validation.
