Ammeter on bluetooth speaker Answered
I'm building a portable bluetooth speaker and need some help. The speaker is equiped with a TPA3116 amp and is power supplied by a 3s lipo battery. On my construction I would like to attach an analog Weston 301 ammeter in order to check my battery's life. Is it possible? The ammeter can measure 0-15A and the battery is 10A. I made an effort but when I attached it on th battery there was a spark.
