⚠ WARNING: lithium batteries can catch fire if they are damaged, shorted or charged incorrectly. Always protect your battery in your wearables: keep it away from sharp edges and pins, never sew through it, insulate every connection, use a protection circuit and a LiPo-compatible charger, and never leave it charging unattended.

Details

A small rechargeable 3.7V lithium polymer battery with bare black and red wires and no connector, ready to solder straight to a charging board or your circuit. At just 5.5 grams and 4 mm thin, it is light enough for wearables and has about 5 times the capacity of our 110mAh battery.

  • Voltage: 3.7V nominal (4.2V fully charged)
  • Capacity: 600mAh
  • Model: 402530
  • Size: about 30 mm long x 25 mm wide x 4 mm thick
  • Weight: 5.5 g
  • Leads: bare black (negative) and red (positive) wires, no connector

How long will it run?

As a guide, for a strip of 10 WS2812B (NeoPixel) LEDs driven by a small ESP32 dev board (roughly 80mA while running):

  • Gentle animations at low brightness: about 2.5 to 3 hours
  • Bright colour effects: about 1 to 1.5 hours
  • All 10 LEDs at full white: about 50 minutes

These are estimates. Real run time depends on your board, brightness and effects.

Charging it

Pair it with our Lithium Battery Charging Board, a tiny USB-C charger with built-in protection that is small enough to sew into a garment. Solder the battery wires to the board, red to positive and black to negative.

Safety and shipping

  • Check polarity before connecting anything. Confirm red is positive with a multimeter if you are unsure.
  • Keep the two bare wires apart so they cannot touch and short. Cover each with heat shrink or tape as soon as you cut or solder them.
  • Do not puncture, crush or short the battery.
  • Limit of 3 batteries per order in total, due to postal regulations for lithium batteries. Each is securely wrapped for shipping.
