21V Portable Output Power/18650 Battery Charger BundleDayton 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. 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
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 the 19.5 V power supply and the over/under charge circuit prevents correctly installed batteries from overcharging and fully discharging, shortening their life. This LBB-5S battery kit includes a power supply 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 the included Dayton Audio LBB-5CL push button and LED kit to view status externally. 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.
Note: The Dayton Audio LBB-5S is an independent battery holder board and it's design is not for Dayton Audio KAB boards. Use Dayton Audio battery board KAB-BE with Dayton Audio KAB Bluetooth amp boards.
