Fahimtar Iyakoki: Haƙuri na Wutar Lantarki na Kariya
Fakitin baturi na lithium galibi ana sanye su da Hukumar Kula da Kariya (PCB) don hana wuce gona da iri, firgita, da gajerun kewayawa. Maɓalli mai mahimmanci na wannan PCB shineƙarfin lantarki jure ƙimar MOSFETs(na'urorin lantarki masu sarrafa wutar lantarki).
Misali Yanayi:
Ɗauki fakitin baturi LiFePO4 mai cell guda biyu a matsayin misali. Kowane fakiti yana da cikakken cajin ƙarfin lantarki na 14.6V (3.65V kowace tantanin halitta). Idan an haɗa su a jeri, haɗin ƙarfin ƙarfin su ya zama29.2V. PCB daidaitaccen kariyar baturi 12V yawanci ana tsara shi tare da MOSFETs da aka ƙididdige su35-40V. A wannan yanayin, jimlar ƙarfin lantarki (29.2V) ya faɗi cikin kewayon aminci, yana barin batura suyi aiki yadda yakamata a jeri.
