Dayton Audio LBB-5v2 5 x 26650 Lithium Battery Charger Board / Module
Dayton Audio's LBB-5v2 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 26650 Li-Ion batteries (sold separately). It's small enough to fit inside a medium size portable speaker and has multiple 21 VDC outputs to power an amp, tone control, Bluetooth, and other preamp component boards. It also has a 12 VDC output to power lower voltage preamp/accessory boards. Enjoy the extended listening time you get from Li-Ion batteries on a single charge. 26650 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 5000mAh batteries.
There's no need to remove the batteries from the holder because the Dayton Audio LBB-5v2 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-5v2 battery board needs a 5 to 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. Another way to charge the board is with a solar panel that doesn't put out more than 19 VDC. Plug the solar panel into the WACO jack marked Solar Panel. 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 separately) to view status externally. The LBB-5CL also comes with input and output charging and power cables.A power supply must be plugged into the holder for the battery board to have power output after installing or reinstalling batteries. The polarity of the batteries must match the polarity of the battery holder to prevent damage.
Note: The Dayton Audio LBB-5 is an independent battery holder board and its design does not work with Dayton Audio KAB board's built-in charge circuit. Use Dayton Audio battery board KAB-BE with Dayton Audio KAB Bluetooth amp boards.
