The capacity of the battery is about 55AH, which means that it can be discharged for 55 hours at a current of 1A. An ordinary small audio speaker is about 40W, 160W with four speakers, and the battery voltage is 12V. Then the discharge current is 13.3A, which can be used for 4.1 hours. Of course, this is just a simple calculation based on the rated power, and it will not always be at the rated power during use. The number and power of the speakers are different, the value is also different. It should be noted that after 4.1 hours, there will be no electricity and no fire, so if you want to be able to start a fire, it is best to listen to music for no more than 1 hour after turning off the fire.

Charging the battery is a long process. If you want to charge it fully, it is best to remove it and charge it with a battery charger, which takes more than ten hours. If you use a generator to charge the car during normal driving, you don't need to charge it once, because the charging speed is faster in the early stage, and it is very slow in the later stage. It is very difficult to charge, unless the engine is maintained at two or three thousand revolutions for a few hours. Therefore, as long as the fire can be ignited the next day, you can charge it little by little as you use the car every day. Generally, keep the engine at about 1500 rpm and charge for half an hour, and leave it overnight to ignite the next day.
