Overview

Parallax 28989 Li-ion Power Pack Charger Full Kit

The Li-ion Power Pack-Charger – 2 Cell is an integrated storage cell and charging system on a single 3” x 4” printed circuit board. It's compatible with most 18650-size Li-ion cells.

Features:

  • PCB-mounted cell holders with on-board charging circuitry
  • Multiple power input/output options
  • On-board output fuse protection
  • Nominal 7.4 VDC output; 8.2 VDC maximum
  • Standard 3” x 4” PCB footprint integrates well with the Board of Education® (28150), Propeller™ Proto Board (32212), or any application needing a reliable power supply with an integrated charging system
  • Automatic charge/discharge switching circuitry
  • Holds two rechargeable 3.7 volt Li-ion 18650-size cells
