11.1 Volt 3.000 mA 3 hücreli li-po pilim için cut-off devresi lazım, minimum 9 voltta gerilimi kesmesi gerekiyor. Uygulama FM telsiz amplifikatörde kullanılacak, şu anda çalışan 741 ve röleli devre 30-35 mA boşta harcadığından hoşuma gitmiyor. 3.7 voltluk Li-po'ya sahip her cihazda bu özelliik var, fakat 11.1 voltta örneğini bulamadım. Malum, hücre başına 3 voltun altı bu piller için ölüm demek.
