SPIDER Automation | 3.7V 165mAh Micro Li-Po Battery | PCM Protected
The 3.7V 165mAh Micro Lithium Polymer Battery is a compact rechargeable battery designed for small electronic devices, portable gadgets and embedded systems. Its slim form factor makes it suitable for applications where available installation space and overall device weight are important design considerations.
The battery features an integrated Protection Circuit Module (PCM) and is intended for compatible 3.7V rechargeable battery applications. With its low-capacity format and lightweight construction, it can be incorporated into compact electronics, IoT devices and other low-power systems.
Product Overview & Battery Design
Lithium Polymer batteries use a lithium-ion-based rechargeable cell design with a polymer-based electrolyte system. Their pouch-style construction allows manufacturers to produce compact battery formats suitable for space-constrained electronic products.
This micro battery is designed for applications requiring a 3.7V nominal supply. Its PCM protection circuit provides an additional battery-management layer, while the compact dimensions support integration into small electronic enclosures.
Technical Features & Functional Characteristics
- Compact Li-Po Construction: Slim battery format suitable for small electronic products and embedded designs.
- Rechargeable Battery: Designed for repeated charging and discharging using a compatible single-cell Li-Po charging system.
- PCM Protection: Includes a Protection Circuit Module as specified in the product description.
- Low-Capacity Power Supply: Suitable for low-power applications requiring a compact rechargeable energy source.
- Lightweight Design: Supports portable electronics where battery weight is a significant design consideration.
- Low Self-Discharge Characteristics: The supplier describes a low self-discharge design for reduced charge loss during storage.
- No Memory Effect: Does not require routine full discharge before recharging, unlike certain older rechargeable battery technologies.
Electrical Configuration & Discharge Characteristics
The battery is designed around a single-cell 3.7V nominal Li-Po configuration. Its stated 1C discharge rate corresponds to a nominal current calculation of 165mA based on the rated capacity. Actual permitted continuous and peak current should be considered according to the battery manufacturer’s detailed specifications.
For conventional single-cell Li-Po charging, use a dedicated lithium-ion/Li-Po CC/CV charging circuit with a maximum charge voltage of 4.2V. The PCM is a protection circuit and should not be treated as a substitute for a suitable charging controller.
Applications
The compact dimensions and rechargeable design make this battery suitable for compatible low-power electronic products and embedded applications.
- Electronics Gadgets: Provides rechargeable power for compact electronic gadgets designed for a 3.7V Li-Po supply.
- IoT Sensor Nodes: Suitable for low-power sensing devices that require a small rechargeable energy source.
- Portable Devices: Supports compact portable electronics where battery size and weight are important design factors.
- Wireless Electronics: Can power compatible wireless modules and small communication devices within the battery’s discharge limits.
- Electronic Toys: Suitable for small electronic toys designed around a single-cell Li-Po battery system.
- Embedded Electronics: Can be integrated into compact embedded projects with suitable charging and power-management circuitry.

Connection & Operating Recommendations
Lithium Polymer batteries require suitable charging, electrical connections and handling practices. Use the battery only with equipment designed for a single-cell 3.7V Li-Po power source.
- Use a Compatible Charger: Charge with a dedicated single-cell Li-Po CC/CV charging circuit designed for a 4.2V maximum charge voltage.
- Respect the Discharge Rating: Keep the load within the specified discharge capability and account for any startup or transient current demand.
- Observe Polarity: Connect the battery positive and negative terminals according to the equipment’s input requirements.
- Avoid Physical Damage: Do not puncture, crush, bend sharply or damage the battery pouch.
- Control Operating Temperature: Keep operation within the stated temperature range and protect the battery from direct sunlight and excessive heat.
- Allow Cooling Before Charging: Do not charge the battery while it is still warm after use. Allow it to return to a suitable temperature first.
- Disconnect During Storage: Disconnect the battery from equipment when it is not in use and store it in a suitable non-conductive, fire-resistant location.
- Prevent Short Circuits: Keep the terminals insulated from conductive objects and avoid incorrect wiring.
