Ka ho phahama ha ‘maraka oa polokelo ea matla, lik’hamphani tse ling tsa betri ea matla li sebelisitse litšebeletso tsa polokelo ea matla lilemong tsa morao tjena, li bula limmaraka tse ncha tsa lisebelisoa tsa libeteri tsa lithium iron phosphate. Ka lehlakoreng le leng, lithium phosphate e na le litšobotsi tsa bophelo bo bolelele, polokeho, bokhoni bo boholo, le ts’ireletso ea tikoloho. Ho fetisetsoa tšimong ea polokelo ea matla ho ka atolosa ketane ea boleng le ho khothalletsa ho thehoa ha mekhoa e mecha ea khoebo. Ka lehlakoreng le leng, sistimi ea polokelo ea matla e hoketsoeng betri ea lithium iron phosphate e fetohile khetho e ka sehloohong ‘marakeng. Ho latela litlaleho, libeteri tsa lithium iron phosphate li ‘nile tsa sebelisoa bakeng sa ho feto-fetoha ha maqhubu a libese tsa motlakase, literaka tsa motlakase, liteishene tsa basebelisi le liteishene tsa grid.
