Ibhetri yeLithium esemgangathweni 3.7V okanye 4.2V iyafana. Kuphela nje ukuba ileyibhile yomenzi yahlukile. I-3.7V ibhekisa kumbane weqonga (oko kukuthi amandla ombane aqhelekileyo) akhutshwa ngexesha lokusetyenziswa kwebhetri, ngelixa i-4.2V ibhekisa kumbane xa ibhetri itshajwe ngokupheleleyo. Iibhetri ze-lithium eziqhelekileyo ezitshajwayo 18650, i-voltage isemgangathweni 3.6 okanye 3.7v, xa ihlawulwe ngokupheleleyo yi-4.2v, oku kunento encinci yokwenza amandla (umthamo), umthamo oqhelekileyo weebhetri ze-18650 ukusuka kwi-1800mAh ukuya kwi-2600mAh, (18650 amandla ebhetri amandla Ikakhulu i-2200 ~ 2600mAh), umthamo oqhelekileyo ude ube nomgangatho we-3500 okanye i-4000mAh okanye ngaphezulu.

Ngokuqhelekileyo kukholelwa ukuba ukuba i-voltage engekho yomthwalo webhetri ye-lithium ingaphantsi kwe-3.0V, ithathwa njengento ephelile (ixabiso elithile lixhomekeke kumda webhodi yokukhusela ibhetri, njengephantsi njenge-2.8V kunye ne-3.2 V). Uninzi lweebhetri ze-lithium azikwazi ukukhutshwa nge-voltage engekho ngaphantsi kwe-3.2V, ngaphandle koko ukukhutshwa ngokugqithiseleyo kuya kulimaza ibhetri (ngokubanzi, iibhetri ze-lithium kwimarike zisetyenziswa ngokusisiseko kunye nebhodi ekhuselayo, ngoko ke ukukhutshwa ngokugqithiseleyo kuya kubangela ukuba ibhodi yokukhusela ingaphumeleli. Ukuqaphela Ibhetri, ngoko ke ayikwazi ukutshaja ibhetri). I-4.2V ngowona mlinganiselo uphezulu wombane wokutshaja ibhetri. Ngokuqhelekileyo kuqwalaselwa ukuba ibhetri ihlawuliswe ngokupheleleyo xa i-voltage engekho yomthwalo webhetri ye-lithium ihlawuliswa kwi-4.2V. Ngethuba lenkqubo yokutshaja ibhetri, i-voltage yebhetri inyuka ngokuthe ngcembe ukusuka kwi-3.7V ukuya kwi-4.2V, kwaye ibhetri ye-lithium ayinakuhlawuliswa. Ukuhlawula i-voltage engekho mthwalo ngaphezu kwe-4.2V, ngaphandle koko iya kulimaza ibhetri. Olu luphawu olukhethekileyo lweebhetri ze-lithium.
