SPIDER Automation | 3.7V 35mAh Micro Li-Po Battery | PCM Protected Ultra-Compact Power Source
The 3.7V 35mAh Micro Li-Po Battery is an ultra-compact rechargeable power source designed for miniature electronic devices, portable products and embedded systems. Its small pouch construction allows integration into assemblies where available space and battery weight are critical 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 compact form factor and low discharge-rate specification make it suitable for miniature electronic systems requiring a small rechargeable energy source.
Technical Features & Functional Characteristics
- Ultra-Compact Battery Format: Small pouch construction supports integration into miniature 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.
- Low Discharge-Rate Specification: The stated 0.2C discharge rate corresponds to approximately 7mA at the specified capacity.
- Lightweight Construction: Its low mass helps minimise the battery’s contribution to the overall weight of miniature electronic products.
- Small Physical Profile: The compact pouch format supports installation in products with very limited internal space.
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.
Applications
