As a member of JAB(Audio Amplifier Boards designed for Jukecase) series, JAB2 offers the wireless solutions with Bluetooth module integrated and can be powered by lithium batteries directly. This is the mono version, which is capable of delivering 100W @ 2Ohm with a Texas Instruments TPA3116 chip to achieve high efficiency. The module dissipates only 0.72W with no signal when in ON mode (around 0.07W when in stand-by mode). Optimized heat sink design increases its reliability. Over current protection and over temperature protection are included to extend the longevity of the amplifier board. All these features make it a good choice for portable Bluetooth speakers.

Hello, i wonder if i can use this amp with a 5S lithium protection board. My question is, do i have to buy the BCPB3 without charging or the BCPB4 with charging? Aka does this amp have charging possibilities?

Hi, Marcus. Thank you for your interest in our products. You can use BCPB3/BCPB4 to power JAB2-1100. The charging circuit employed in JAB2 only works for 3S 18650 battery board without charging function. If you want to charge BCPB3/BCPB4, please connect BCPB3/BCPB4 with a power supply whose voltage is within the recommended range. Wish this could help you.
