Dayton Audio KAB-BE 18650 Battery Extension Board for Bluetooth Amplifier Boards
Lithium battery power is your best option when building high power portable sound projects. Connect and charge three 18650 lithium batteries to your KAB board using the Dayton Audio KAB-BE. Enjoy prolonged listening with this advanced power option. Key Features Under/over voltage protection prevents over charging the batteries Voltage balancing keeps the sound playing even if one of the batteries is weaker than the others Holds three 18650 Li-Ion batteries (sold separately) Built-in 8" 4-conductor cable plugs directly into KAB Bluetooth amp boards The Dayton Audio KAB-BE Li-Ion battery charging board holds three 18650 batteries (sold separately). This charging board has built in under/over voltage protection circuits for safe charging and battery longevity. It balances different voltages between batteries in case one battery discharges faster than the other ones. A 19 VDC, 1-5A power adapter works best for charging batteries contained in this board. Additional boards can be sequenced together to provide longer playing time. Please note: When removing batteries from the KAB-BE, the charging adapter must be plugged in momentarily after the new batteries have been inserted. Failing to do so will prevent the amp board from powering up. Specifications: • Included cable: 8" 4-conductor • Board dimensions: 2.68" H x 3.61" L x 1.15" W.
Dayton Audio KAB-FC Functional Cables Package for Bluetooth Amplifier Boards
These four 20" function cables offer additional options for customizing Dayton Audio KAB Bluetooth amp board sound projects. Key Features 3.5 mm AUX-in cable with jack provides a way to play music with non-Bluetooth devices External volume control with cable and knob to keep the sound under control Battery cable for true portable projects On/off power cable for optional power switch Use the KAB-FC cables to customize any Dayton Audio KAB project. This four-cable kit comes equipped with Molex Mini Fit Jr connectors for easy termination to the board, and each cable is 20" in length. The AUX-in cable with 3.5 mm jack feeds music from any analog source directly to the Dayton Audio KAB boards, enabling audio play from almost any non-Bluetooth source. The volume control with cable and knob lets you manually control sound levels, and mounts into a 0.3" hole. The volume control without knob is 0.24" (6 mm) in diameter. The battery cable is for portable projects where AC or 12 VDC car power are not available. Multiple types of rechargeable batteries work with this cable and the board will charge the batteries when using an adapter with 15 - 24 VDC. Output wattage of the power adapter should never exceed 30 watts, as there is no under/over charging protection built in to the KAB boards. Using the on/off power cable and SPST switch cuts power to the entire board, but still provides power to the connected batteries for charging.
