Lithium Ion Polymer Battery- 3.7v 150mA

This ultra-thin Lithium Polymer battery packs 150mAh (0.6Wh) at 3.7V nominal (3.0–4.2V range) with pre-crimped genuine 2-pin JST PH and PCM protection—ideal for small wearables or Feather backups. Tailored for first-year engineering students powering low-drain IoT nodes safely.

PCM prevents overcharge (>4.2V cutoff), over-discharge (3.0V cutoff), and shorts; polarity matches Adafruit chargers/boards. Smooth JST mating avoids snags; requires LiPo-specific charger (not NiMH).

Safety Rules

• Charge/use supervised only.
• No bending/crushing/shorts.
• Inspect wiring regularly.
• Expert use recommended.
