Lokhu kubuka okuphelele kubonisa ukuthi ubuchwepheshe besimanje bebhethri lamandla, kusukela kumakhemikhali ayisisekelo kuya ekuhlanganisweni kwesistimu, buvumela kanjani izinhlelo zokusebenza ezihlukahlukene. Ukuthi ukhetha ibhethri le-lithium elingu-48v elingcono kakhulu ukuze usebenzise ikalishi legalofu noma ukuklama{2}}isitoreji samandla esikhulu, ukuqonda lezi zimiso zobuchwepheshe kuqinisekisa ukukhethwa nokusebenza kwesistimu okuphelele.
