Jika di atas adalah Power bank yang digunakan untuk menampilkan indikator berbasis Digital, di bawah ini adalah Power Bank yang akan menampilkan Indikator berbasis Analog. Dalam hal ini indikator yang di maksud adalah berupa LED.
Cara kerja singkat dari rangkaian ini didasarkan pada switching dari dua transistor BC547 sekaligus sebagai driver untuk LED indikator. Dioda zener yang terhubung dengan transistor T1 berfungsi sebagai penstabil tegangan yang disesuaikan dengan baterai yang akan digunakan. LED hijau akan menyala apabila tegangan baterai normal atau pengisian baterai telah penuh. Resistor R1 dan VR 5K disetting untuk menyesuaikan bias dari transistor T1 secara perlahan. Ketika transistor dalam keadaan bekerja, maka T2 akan tertarik ke ground sehingga LED merah akan padam.
Sebenarnya ini hanyalah segelintir rangkaian dari sekian banyak rangkaian Kontrol Level Baterai yang ada. Baik yang bentuknya Analog ataupun Digital yang berbasis Mikrokontroler.
