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.
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.
