Polymer Lithium Ion batteries offer superior energy density with this 400mAh battery being only 6mm in height!

With a cell voltage of 3.7 Volts, these batteries are perfect for microcontrollers and other low power devices, especially when paired with a good DC/DC regulator for logic level output.

Built into the battery is an over-voltage, over-current, and minimum voltage protection circuit which makes them even easier to use, although care must be taken when using LiPo batteries. Incorrect charging, usage, or physical damage to the battery can result in a fire. Be sure to only use a specific LiPo charger.

Although these cells are rated for 2C continuous discharge, the wiring and connectors are only rated up to 1A, so be sure to take that into account when determining your power requirements.

Remember that like any power source, you should be extra careful not to short the power pins as doing so can damage your battery and cause it to swell/overheat, rendering it unusable and dangerous.

Tech Specs:

  • 400mAh capacity
  • 38x25x6mm
  • 11g
  • 2C continuous discharge
  • Great energy retention with low self-discharge rates (<8% per month)
  • Reliable under extreme conditions (-10 to 50C)

    This item is small and easily fitted the case I was using to house the project. The battery worked perfectly, charged ok and did what I wanted. But the processor board I chose (Adafruit HUZZAH ESP8266) consumes too much power to make this battery a real option. (USB bridge chip remains on all the time, 6.4ma). I am considering a number of different board which would make this battery an excellent choice. (Posted on 11/09/2017)

    I don't buy LiPo batteries unless I can trust the quality to be of a high standard and that's exactly what you get here from Core.

    Neat little battery with a really small footprint - perfect for small projects and works a treat when combined with Powerboost 500 charger. (Posted on 20/04/2017)
