No more need to remove rechargeable "AA" cells and place them into a separate charging station, or replace non-rechargeable alkaline cells. 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. We recommend our High Capacity Li-in cell and 7.5 VDC 1 A POWER SUPPLY

Key Features:    

• Fits into the Boe-Bot robot’s chassis, replacing the 4-cell AA battery pack
• Holds two rechargeable/replaceable 3.7 V 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.
• Comes with all hardware and cables necessary for installation into your existing Boe-Bot           
• Automatic charge/discharge switching circuitry

Application Ideas:

• Portable power for data-logging applications
• Mobile Robots - especially the Boe-Bot
• Stingray Robot (#28980)
