Prototyping and Engineering Tips from Robogears

• Precise Charging: To maximize the lifespan of such a small cell, use a dedicated Li-Po charger. We recommend setting your charging current to no more than 100mA–150mA; charging too fast (above 1C) can cause heat buildup and reduce the battery's health.

• Mounting in Tight Spaces: Because the casing is a soft pouch, use double-sided "tissue tape" rather than thick foam tape to keep your project as thin as possible. Ensure no sharp solder points on your PCB are pressing against the battery pouch.

• Low-Power Logic: This battery is perfect for ESP32-C3 or nRF52-series "Low Power" Bluetooth projects. In deep-sleep mode, a 250mAh cell can keep a sensor alive for weeks or even months depending on the transmission interval.

• Wiring Strain Relief: The lead wires on micro batteries are delicate. Apply a tiny drop of hot glue at the wire-to-pouch junction to act as a strain relief if your project involves movement or frequent battery handling.
