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
• Multiple LED indicators provide charge readiness information for each individual cell; status key for the LED indicators is printed on the board.
• Aggressive holders retain cells in any board orientation and in moderate shock environments, such as mobile robotic applications. Cells are not permanent, and are easily replaced.
• Dedicated circuitry continuously monitors the charging process to ensure safety, efficiency, and to maximize the number of charge/discharge cycles of each cell.
