Uhlelo lokuphatha ibhethri le-master-slave lungaqapha i-voltage yeseli, iphakethe lebhethri eliphelele, izinga lokushisa kweseli, ukushaja nokukhipha amapharamitha amanje kanye neminye yesistimu yebhethri ye-lithium ngesikhathi sangempela nangokunemba okuphezulu, futhi yenze ukuhlaziya okusheshayo nokucutshungulwa ukuze kunikeze ukushajwa kwebhethri ye-lithium ehambisanayo, ukukhishwa ngokweqile, okungaphezu kwamanje, izinga lokushisa elingaphezulu, i-short-circuit kanye nezinye izindlela zokuvikela ukuze kuqinisekiswe ukusebenza okuphephile nokuthembekile kwesistimu yebhethri ye-lithium nokwandisa impilo yesevisi yebhethri ye-lithium.
Isicelo: amandla okuqalisa imoto enkulu, isitoreji samandla elanga, imoto yobunjiniyela, isivinini esiphansi imoto enamasondo amane, i-RV nanoma iyiphi enye idivayisi ofuna ukuyibeka kuyo.
