Lithium Ion Polymer Battery with Short Cable - 3.7V 350mAh
100 units available with a short lead time.
A compact 3.7 V 350 mAh lithium-ion polymer (LiPo) battery with a short cable and genuine 2-pin JST-PH connector. The slim, lightweight form factor makes it ideal for wearables, IoT devices, and portable electronics projects.
The battery includes built-in protection circuitry that guards against overcharging (above 4.2 V), over-discharge (below 3.0 V), and output short circuits. The genuine JST connector clicks smoothly in and out of matching jacks without snagging.

Safety Warning: Only use a LiIon/LiPo constant-voltage/constant-current charger at 350 mA or less (100–350 mA recommended). Do not use NiMH, NiCad, or lead-acid chargers. Do not short, bend, crush, or puncture the battery. Never charge or use unattended. Always check that your charger's JST polarity matches before connecting — reversed polarity can destroy the battery.
