LiPo battery 2000mAh JST 1.25 / Lithium Ion Polymer

This lithium-polymer battery of type 503290 delivers 2000 mAh at a nominal voltage of 3.7 V and is equipped with an integrated protection circuit (PCM) against overcharge, deep discharge, overcurrent, and short circuit. It can be directly connected to development boards and charging modules via the JST 1.25 connector. This makes the battery ideal for battery-powered projects with Arduino, ESP32, LoRa, and Raspberry Pi Pico. Always compare the polarity of the connector with the target board before the first connection – the pinout is not identical for all manufacturers.

Properties:

• Integrated protection circuit (PCM) against overcharge, deep discharge, overcurrent, and short circuit
• Capacity of 2000 mAh with compact pouch design
• JST 1.25 connector for direct connection to boards and charging modules
• Slim design for space-saving installation in housings and DIY projects

Application examples:

• Power supply for LoRa and Meshtastic nodes with JST-1.25 connector
• Mobile operation of ESP32 and XIAO projects
• Power source for GPS trackers and portable measurement technology
• Buffer battery for boards with integrated charge management
