Ibhethri kweyakhoibhayisikili likagesiyakhiwe ngamaseli amaningana.Iseli ngalinye line-voltage ephumayo engashintshi.Kumabhethri e-Lithium lokhu kungu-3.6 volts ngeseli.Akunandaba ukuthi iseli likhulu kangakanani.Isakhipha amandla angu-3.6 volts.Amanye amakhemistri webhethri anamavolthi ahlukene ngeseli ngayinye.Kumaseli e-Nickel Cadium noma e-Nickel Metal Hydride i-voltage ibingu-1.2 volts iseli ngalinye.

Ama-volts okukhiphayo kusuka kuseli ayahluka njengoba ephuma.Iseli ye-lithium egcwele ikhipha okusondele ku-4.2 volts ngeseli uma ishajwe ngo-100%.Njengoba ingqamuzana likhipha, lehla ngokushesha libe ngu-3.6 volts lapho lizohlala khona ku-80% womthamo walo.Uma isisondele ekufeni yehla ibe ngu-3.4 volts.Uma iphuma ibe ngaphansi kokungu-3.0 okukhiphayo iseli izolimala futhi ingase ingakwazi ukushajwa kabusha.

Uma uphoqa iseli ukuthi likhiphe umsinga ophakeme kakhulu, i-voltage izokwehla.Uma ufaka umgibeli osindayo ku-e-ibhayisikili, kuzodala ukuthi injini isebenze kanzima futhi idwebe ama-amps aphezulu.Lokhu kuzodala i-voltage yebhethri yehle ukwenza isikuta sihambe kancane.Ukukhuphuka imimango kunomphumela ofanayo.Uma uphakeme umthamo wamaseli ebhethri, uzoncipha ngaphansi kwamanje.Amabhethri omthamo ophakeme azokunikeza i-voltage encane kanye nokusebenza okungcono.
