Dayton Audio LBB-3v2 Quick Start Wiring Guide

The LBB-3 compact battery holder board delivers high current portable power to small amplifiers, 50W amp boards, or other 12 VDC projects by combining the voltage from three 18650 Li-Ion batteries (sold separately). It's small enough to fit inside a portable speaker and has multiple 12 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 50W amplifier or amp board use at least 2600mAh batteries.

There's no need to remove the batteries from the holder because the LBB-3 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-3 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. To view charging and battery status press the push button on the battery board, or use the LBB-5CL push button and LED kit (sold separately) to view status externally and also adds extra DC input/output options. 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-3v2 battery board outside your project use the 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 J5 socket. Make sure you plug into the expansion socket and not the external LED socket.

Note: The LBB-3 is an independent battery holder board and it's design is not for KAB boards. Use the battery board KAB-BE with the KAB Bluetooth amp boards.
