Protection Circuit and Temperature Feedback
The PCBA parts list specifies a R5478N101CD protection IC, 8205 MOSFET, and 10K ohm +/-1%, B3435 NTC. Protection settings include over-charge, over-discharge, over-current, and short-circuit protection values in the datasheet, while the NTC gives device designers a supported path for temperature-aware pack integration.
Operating Range and Life Test
The operating temperature range is 10~45 degC for charging and -20~60 degC for discharging. Cycle life is specified as not less than 600 cycles under the defined 0.2C charge/discharge test until capacity is reduced to 80% of rated capacity. Self-discharge retention is listed as not less than 85% of initial capacity after 28 days at 20+/-5 degC.
Application Fit
This compact protected lithium polymer battery pack is suitable for small rechargeable electronics, IoT modules, smart sensors, handheld meters, wearable modules, and compact tracking equipment where a slim pack, connectorized leads, protection circuit, and NTC support are required.
