SPIDER Automation | 3.7V 450mAh Micro Li-Po Battery | PCM Protected Rechargeable Power Source
The 3.7V 450mAh Micro Li-Po Battery is a compact rechargeable power source designed for portable electronic products, IoT devices and embedded systems. Its slim pouch construction allows integration into assemblies where available space and battery weight are important design considerations.
Featuring a nominal voltage of 3.7V and an integrated Protection Circuit Module (PCM), this battery is intended for compatible single-cell lithium-polymer applications. Its 450mAh capacity and 1C discharge-rate specification make it suitable for compact electronic systems requiring a rechargeable power source.
Technical Features & Functional Characteristics
- Micro-Size Battery Format: Compact pouch construction supports integration into portable electronic enclosures and space-limited assemblies.
- Rechargeable Li-Po Chemistry: Designed for repeated charging and discharging using a compatible single-cell lithium-polymer charging system.
- Integrated PCM: Includes a battery protection circuit. Specific protection functions and voltage thresholds are not stated in the supplied specifications.
- 1C Discharge Rate: The stated discharge rate corresponds to a nominal current of 450mA based on the rated capacity.
- Lightweight Construction: Its 10g weight helps minimise the battery’s contribution to the overall weight of compact electronic products.
- Slim Physical Profile: The flat pouch format supports installation in products with limited enclosure depth.
Electrical Configuration & Charging Requirements
This is a single-cell 3.7V nominal lithium-polymer battery. Use a compatible single-cell Li-Po charging circuit with a regulated 4.2V CC/CV charging profile. The nominal voltage is not the battery’s full-charge voltage.
- Charging Voltage: Use a dedicated 4.2V single-cell Li-Po charging circuit.
- Charging Current: Select a charging current appropriate for the battery capacity and manufacturer’s charging specifications.
- Protection Circuit: The integrated PCM is part of the battery assembly; it does not replace a suitable charging circuit.
- Load Compatibility: Ensure the connected device operates within the battery’s voltage and discharge capabilities.
- Connection: Confirm connector type, wire polarity and terminal arrangement before integration.
