Kuchengeta lithium iron phosphate mabhatiri mukati meiyo yakakwana 20-35 dhigirii renji inogona kaviri kana katatu kutenderera hupenyu kana uchienzaniswa nekushanda patembiricha yakakwira. Zvidzidzo zvinotaridza mabhatiri ane inoshanda yekudziya kwekutonga inogara 3,000+ macycles maringe ne1,000-1,500 macycle pasina kutonhodza.
Kutonhora kwemvura kuri nani pane kutonhora kwemhepo here?
Liquid kutonhora inobata 5-10x yakakwirira kupisa inoyerera pane kutonhora kwemhepo uye inochengetedza zvirinani tembiricha yakafanana, asi inodhura 3-5x yakawanda uye inowedzera kuoma. Pakupisa mitoro iri pasi pe200W, kutonhora kwemhepo kunokwana. Pamusoro pe500W, kutonhora kwemvura kunove kwakakosha pakuita kunoshanda.
Active kutonhora inoshandura kudziya kwekutonga kubva kune inomisa chinhu kuita inogonesa tekinoroji. Nekushandisa simba rine mwero kutyaira nzira dzekufambisa kupisa, masisitimu aya anobvumira zvikamu kuti zvishande pamazinga epamusoro ekuita, munzvimbo dzakaoma, uye kwenguva yakareba yehupenyu. Sezvo kupisa kwakanyanya kuri kuramba kuchiwedzera pamagetsi, mabhatiri, nemidziyo yekombuyuta, kutonhora kunoshanda kunobva pakuvandudzwa kwesarudzo kuenda kune zvakakosha-kunyanya mu lithium iron phosphate bhatiri rekushandisa uko kutonga tembiricha kunotara zvakananga kuchengetedzeka, kuita, uye kugona kwehupfumi.
