Yunjie stereo undervoltage battery power what happened

Yunjie Audio is a portable outdoor audio system powered by a battery. Undervoltage means that the battery voltage should already be charged. Although the stereo can still work at this time, the output power becomes smaller, the distortion becomes bigger, and the battery is in overdraft status, which is very easy to cause damage.

The capacity of the built-in battery provided by the manufacturer is relatively small, and cannot satisfy the high-power situation of continuous long-duration square dancing.

Solution:

1-use the very popular 12V electric bicycle battery as the external battery;

2-use the micro-power FM transmitter to transmit signals at an effective distance of 100 meters, and the dancers will receive the signals on their FM Walkman, which will provide a much better sound quality than the Yunjie Audio products. The sound quality is much better than the products of "Yunjie Audio", and there is no worry about disturbing the public.
