Product details
Dayton Audio LBB-5S 18650 21V Lithium Battery Board with Balance & Charge Protection
Dayton Audio's LBB-5S battery holder board delivers high current portable power to small amplifiers, 200W amp boards, or other 21 VDC projects by combining the voltage from five 18650 Li-Ion batteries (sold separately). It has the same footprint as compact Sure/Wondom boards and is small enough to fit inside a portable speaker. The LBB-5S has multiple 21 VDC outputs to power an amp, tone control, Bluetooth, and other preamp component boards. Enjoy the extended listening time you get from Li-Ion batteries on a single charge. 18650 Li-Ion batteries come in a variety of amperages, and to get the longest playtime from a 200W amplifier or amp board use at least 2600mAh batteries.
There's no need to remove the batteries from the holder because the Dayton Audio LBB-5S has a built-in charge circuit. Just plug in a power supply and the over/under charge circuit prevents correctly installed batteries from overcharging and fully discharging, shortening their life. The LBB-5S battery board needs a 24 VDC power supply (sold separately) to start the charging process and to start its output power. This enables you to listen to music while the batteries are charging with this amazing battery holder. To view charging and battery status press the push button on the battery board, or use Dayton Audio's LBB-5CL push button and LED kit (sold seperately) to view status externally. The LBB-5CL also comes with input and output charging and power cables.
If you remove a battery, the power supply must be plugged into the holder for the battery board to start working again when the battery or batteries are reinstalled. The polarity of the batteries must match the polarity of the battery holder to prevent damage.
To charge and power 5VDC devices, and recharge the LBB-5S battery board outside your project use Dayton Audio's LBB-5EB. It has two USB ports that put out 2A of current for smart phones, tablets, and other 5 VDC devices. The board also has a 2.1 x 5.5 tip positive DC coax power jack so you don't have to solder in an external charging jack. To make it even easier the LBB-5EB includes a 6-pin 8" wiring harness that plugs directly into the battery board J9 socket.
Note: The Dayton Audio LBB-5S is an independent battery holder board and it's design does not work with Dayton Audio KAB board's built-in charge circuit. Plug the LBB-5S into the two wire DC input on the KAB boards or use Dayton Audio battery board KAB-BE with Dayton Audio KAB Bluetooth amp boards.
