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. We recommend our High Capacity Li-ion Cell and 7.5 VDC, 1 Amp Power Supply.
Features:
- 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.
