The KABD-250 is also CE and FCC ready for certification purposes.
Portable Power Paths
For portable applications, there are three battery holder/charging boards which permit the connection of li-Ion rechargeable batteries to power the board. First is the Dayton Audio LBB-3v2 3-cell 18650 battery holder/charger board that is the same size as the KABD-250 which makes it easy to stack the boards with standoffs. This battery board must use a 5 to 24 VDC power supply. If you desire more wattage output, use the 5-cell 21 VDC Dayton Audio LBB-5Sv2 or LBB-5v2 board. They work with 5 to 24 VDC power supplies. The LBB-5S uses 18650 Li-Ion batteries, and the LBB-5 uses 26650 Li-Ion batteries which delivers more play time. These portable power sources are highly recommended since all three provide under/over voltage protection.
