No need to remove rechargeable "AA" cells and place them into a separate charging station, or replace non-rechargeable alkaline cells anymore. Simply plug in a 7.5 VDC, 1 A wall transformer and the charging circuitry does the rest, automatically. This pack/charging solution can replace up to several thousand "AA" alkaline batteries over the Li-ion cells' lifetime. Two Li-ion 18650-size cells and a power supply are required, not included.
Fits into the Boe-Bot's chassis, replacing the 4-cell AA battery pack
Holds two rechargeable/replaceable 3.7 volt Li-ion 18650 cells
Provides up to 6 hours of continuous motorized operation (depending on cell capacity)
Rechargeable Li-ion cells don't need to be removed from your Boe-Bot for recharging - charging circuitry is built into the board.
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.
Dedicated circuitry continuously monitors the charging process to ensure safety, efficiency, and to maximize the number of charge/discharge cycles of each cell.
