Feem ntau, 3.7vroj teeb lithiumxav tau ib lub "board tiv thaiv" rau kev them ntau dhau thiab kev tso tawm ntau dhau. Yog tias lub roj teeb tsis muaj lub board tiv thaiv, nws tsuas yog siv tau lub zog them ntawm li 4.2v, vim tias lub zog them tag nrho zoo tagnrho ntawm lub roj teeb lithium yog 4.2v, thiab lub zog hluav taws xob tshaj 4.2v. Kev puas tsuaj rau lub roj teeb, thaum them li no, nws yog ib qho tsim nyog los saib xyuas lub xeev ntawm lub roj teeb txhua lub sijhawm.
Yog tias muaj lub rooj tsavxwm tiv thaiv, koj tuaj yeem siv 5v (4.8 txog 5.2 tuaj yeem siv), USB5v ntawm lub khoos phis tawj lossis lub charger 5v ntawm lub xov tooj ntawm tes tuaj yeem siv tau.
Rau lub roj teeb 3.7V, qhov hluav taws xob txiav tawm yog 4.2V, thiab qhov hluav taws xob txiav tawm yog 3.0V. Yog li ntawd, thaum lub roj teeb qhib hluav taws xob qis dua 3.6V, nws yuav tsum tuaj yeem them tau. Nws yog qhov zoo tshaj plaws los siv hom them hluav taws xob tas li 4.2V, yog li koj tsis tas yuav them sai sai rau lub sijhawm them. Kev them nrog 5V yooj yim rau overcharge thiab ua rau muaj kev phom sij.

1. Kev them nqi ntab. Hais txog kev them thaum ua haujlwm online. Txoj kev no feem ntau siv rau hauv cov xwm txheej fais fab thaub qab. Yog tias nws qis dua 12 volts, nws yuav tsis tuaj yeem them, thiab yog tias nws siab dhau, nws yuav cuam tshuam rau kev ua haujlwm ntawm lub voj voog. Yog li ntawd, thaum lub nqi ntab ua haujlwm, qhov hluav taws xob yog 13.8 volts.

2. Rov them dua ib zaug. Hais txog kev them lub roj teeb kom puv kom rov qab muaj peev xwm. Thaum them tag, lub charger tsis raug txiav rau kev ntsuas. Feem ntau, nws yog li ntawm 14.5 volts, thiab qhov siab tshaj plaws tsis pub tshaj 14.9 volts. Tom qab txiav lub charger rau 24 teev, nws feem ntau yog li ntawm 13 volts txog 13.5 volts. Kwv yees li 12.8 txog 12.9 volts tom qab ib lub lim tiam. Tus nqi hluav taws xob tshwj xeeb ntawm cov roj teeb sib txawv yog txawv.

Lub roj teeb lithium ib txwm muaj yog 3.7v, qhov hluav taws xob yog 4.2v thaum them tag, qhov hluav taws xob nominal tom qab kev sib txuas series tsuas yog 7.4v, 11.1v, 14.8v… qhov hluav taws xob tag nrho sib xws (uas yog, qhov hluav taws xob tso zis tsis muaj load ntawm lub charger) yog 8.4v, 12.6v, 16.8v… tsis tuaj yeem yog 12v integer, ib yam li lub sijhawm ntawm cov roj teeb cia kua qaub-acid yog 2v, tag nrho yog 2.4v, sib xws tsuas yog 6v, 12v, 24v… qhov hluav taws xob tag nrho (Tib yam yog qhov hluav taws xob tso zis ntawm lub charger) feem 7.2v, 14.4v, 28.8v… Kuv tsis paub koj yog hom roj teeb lithium dab tsi?
Feem ntau, qhov tso zis ntawm lub charger yog 5V, thiab 4.9 volts kuj yog qhov tsis yog tus qauv. Yog tias koj xav siv lub charger no los them lub roj teeb ncaj qha, nws yuav tsis ua haujlwm, tab sis tsuav yog nws raug them los ntawm lub xov tooj ntawm tes lossis lub dock, nws muaj lub voj voog tswj hwm sab hauv. Nws yuav raug txwv hauv qhov ntau ntawm lub roj teeb lithium, tshwj tsis yog tias lub voj voog puas lawm, tsis txhob txhawj txog qhov no.
Lub roj teeb lithium ib txwm muaj yog 3.7v, qhov hluav taws xob yog 4.2v thaum them tag, qhov hluav taws xob nominal tom qab kev sib txuas series tsuas yog 7.4v, 11.1v, 14.8v… qhov hluav taws xob tag nrho sib xws (uas yog, qhov hluav taws xob tso zis tsis muaj load ntawm lub charger) yog 8.4v, 12.6v, 16.8v… tsis tuaj yeem yog 12v integer, ib yam li lub sijhawm ntawm cov roj teeb cia kua qaub-acid yog 2v, tag nrho yog 2.4v, sib xws tsuas yog 6v, 12v, 24v… qhov hluav taws xob tag nrho (Tib yam yog qhov hluav taws xob tso zis ntawm lub charger) feem 7.2v, 14.4v, 28.8v… Kuv tsis paub koj yog hom roj teeb lithium dab tsi?
