Hello, my son's toy has a battery. The battery he has been using for 3 years has stopped working in the past weeks. I changed the Li-on batteries inside. I measure the output voltage of 14.5V, but the led lights on the battery do not light, the device does not work. The battery is not charging. I did some research and realized that there is a problem with the BQ20X655. I downloaded the TI bq Gas gauge software and made the necessary connections. I tried every way but it didn't work. I keep getting errors. I can't buy the battery separately, it gets expensive with the product. Can you help me?
Please see attached file and thank you in advance.
Best regards,
Jonathan
