Ib qho ntawm cov tshuaj lom neeg yooj yim tshaj plaws ntawmCov roj teeb lithiumyog hom Lithium Iron Phosphate (LiFePO4). Qhov no yog vim lawv tau lees paub tias yog qhov muaj kev nyab xeeb tshaj plaws ntawm cov hom Lithium thiab lawv me me thiab sib dua thaum piv rau cov roj teeb lead acid uas muaj peev xwm sib piv.

Niaj hnub nim no, ib qho kev xav tau ntau yog hloov lub roj teeb ua kua qaub nrogLiFePO4nyob rau hauv ib lub tshuab uas twb muaj lub tshuab them fais fab lawm. Ib qho piv txwv ntawm ib qho yog lub tshuab roj teeb thaub qab. Vim tias cov roj teeb rau kev siv zoo li no yuav siv ntau qhov chaw hauv qhov chaw nqaim, feem ntau yog nrhiav lub txhab roj teeb me dua.

Nov yog yam yuav tsum paub txog:

★12 V cov roj teeb lead acid muaj 6 lub cell. Yuav kom lawv them tau zoo, cov cell no yuav tsum muaj 2.35 volts kom them tau tag nrho. Qhov no ua rau qhov voltage tag nrho rau lub charger yuav tsum yog 2.35 x 6 = 14.1V

★12V LiFePO4 roj teeb tsuas muaj 4 lub cell xwb. Yuav kom them tau tag nrho, nws cov cell yuav tsum tau siv 3.65V volts kom them tau tag nrho. Qhov no ua rau lub charger tag nrho xav tau 3.65 x 4 = 14.6V

Pom tau tias yuav tsum muaj hluav taws xob siab dua me ntsis kom them tau lub roj teeb Lithium kom tag. Yog li ntawd, yog tias ib tug neeg tsuas yog hloov lub roj teeb lead acid nrog lithium, tawm txhua yam li qub, kev them tsis tiav rau lub roj teeb Lithium tuaj yeem xav tau - qhov twg ntawm 70% -80% ntawm kev them tag nrho. Rau qee qhov kev siv qhov no yuav txaus, tshwj xeeb tshaj yog tias cov roj teeb hloov pauv muaj peev xwm hluav taws xob ntau dua li lub roj teeb lead acid qub. Kev txo qhov ntim roj teeb yuav ua rau txuag tau qhov chaw loj thiab kev ua haujlwm ntawm tsawg dua 80% qhov muaj peev xwm siab tshaj plaws yuav ua rau lub roj teeb lub neej ntev dua.
