Turnkey Solution for Portable PowerThe Dayton Audio LBB-5v2 makes harnessing the power of rechargeable lithium-ion batteries an easy endeavor. Simply install five 26650 lithium-ion batteries into the LBB-5v2 to get solid 21V performance. At a total current draw of 10 amps, this battery board produces 210 watts of power.
Sometimes soldering to a circuit board can be intimidating. That's why the LBB-5v2 bypasses the need for any board soldering by providing JST sockets for reliable and convenient connections that allow you to take advantage of all the capabilities that this rechargeable battery board provides.
The Dayton Audio LBB-5v2 is so easy to use, affordable and dependable, it opens the up possibilities for portable electronics projects and products that otherwise may not have been possible. Use the LBB-5v2 to create portable speaker systems, drive motors in robotics projects, power an array of LED's or make life simpler by employing creative iOT (internet of things) solutions. The sky is the limit when portable power is needed.
This board offers six 21V DC output connectors to supply power to various items in your project or product. Remember, all connected devices will share 10 amps of current. Be sure that what you are connecting the LBB-5v2 does not draw more than 10 amps. By having multiple output connectors, it eliminates the need for a power distribution circuit, thus simplifying most designs.
A remarkable point of versatility is that the Dayton Audio LBB-5v2 can recharge on a very wide range of voltages; from a convenient 5V source all the way up to a fast-charging 24V power adapter. You can even plug a solar array into the LBB-5v2 to keep a constant charge in sunny conditions. The recommended average output from the solar array is 19V, charging times will vary depending on the voltage and amperage provided to the LBB-5v2.
Operate the Dayton Audio LBB-5v2 rechargeable battery board with confidence knowing that it provides robust overcharge and undercharge protection. This protection circuitry built into the board maintains safe operation and optimizes the lifespan of the five 26650 lithium-ion battery cells that are housed securely on the underside of the board.

Another great feature of the LBB-5v2 is their array of LED status indicators. Directly on the board you will find a tactile push button that will tell you the battery charge level, indicated by four on-board LED's. In addition, you'll also find a power input LED that shows that the board is connected to a power source and a charging LED that lets you know the board is actively charging; it turns off when charging is complete.
However, once you mount this rechargeable battery board inside an enclosure, the board and its indicators are no longer visible. That's why this board also comes equipped with JST connectors to bring all those status indicators to the outside of your project. By purchasing the (sold separately), you can bring all those important statuses to the outside of your enclosure. With easy to connect pre-terminated LED's, just plug the wires into their correct JST sockets and mount the LED's so they are visible. It's that easy.
Note: Dayton Audio LBB boards are designed to be used and recharged frequently. Balancing technology does use a little current so keep charging the board even when not in use for multiple days. Pull the batteries out when not in use for long periods of time. Charge the board immediately after reinstalling the batteries.
