Lead-acid chargers have higher float voltages (13.6V – 14.4V), which will overcharge a 3S Li-ion pack (12.6V max). Use a dedicated Li-ion charger.
Because these are generic modules, the tolerances vary, but the standard specifications are as follows: xh-m567 datasheet
The XH-M567 datasheet provides detailed information about the module's specifications, features, and operating conditions. The datasheet typically includes the following sections: Lead-acid chargers have higher float voltages (13
Connect your lower voltage supply to and IN- . Measure the output at OUT+ and OUT- . Turn the blue potentiometer clockwise to increase voltage, counter-clockwise to decrease it. The is a high-efficiency Class D digital power
The is a high-efficiency Class D digital power amplifier board designed for dual-channel stereo applications . Built around the popular TPA3116D2 chipset, it delivers a powerful 80W per channel while maintaining a compact footprint, making it a staple for DIY audio enthusiasts and home theater projects. XH-M567 Key Specifications
If your board uses the MC34063 chip, the efficiency is poor (under 70%). If you find a version using the XL6009, the efficiency improves to ~85%.
Never connect a charger to B+/B- terminals – always use P+/P- for charging. Connecting backward will destroy the module.
