Kho ib qho yuav tsis tshwm sim. Kuv muaj ib tus neeg ua haujlwm uas coj kuv yam uas nws tawg thiab kho tsis tau nws tus kheej. Nws yuav lub roj teeb uas siv hluav taws xob weedwhacker thiab nplooj tshuab cua tshuab los ntawm Sam's Club txog li $ 75. Nws suav nrog 2 lub roj teeb thiab lub charger. Yog tias koj nyeem Amazon tshuaj xyuas online txog 1/2 cov neeg uas muaj cov teeb no lossis siv lub roj teeb tsis qhia nws rau leej twg lawv mob siab txog. Nws ua haujlwm ob peb zaug thiab tuag. Ntxiv rau qhov ntawd tom qab. Txawm li cas los xij, hauv kev sim kho qhov no kuv pom tias cov cell sab hauv tseem zoo thiab yog $ 10 txhua lub khw muag khoom vim tias lawv yog cov kab saum toj kawg nkaus Samsung 18650 lithium ion tsis muaj kev tiv thaiv kab mob.

Cov xov tooj ntawm tes tau tshaj tawm ntawm no los ntawm Samsung. 22 amp max tso tawm tsis tu ncua thiab 2 amp teev ntawm kev cia.

Kev hloov roj teeb pob yog kwv yees li $ 75/pob. Qhov ntawd yog tus nqi ncaj ncees vim tias tus nqi thiab qhov zoo ntawm cov cell sab hauv, tab sis kuv tsis xav kom hloov pauv lawv. Cov kev hloov pauv yuav tsis nyob ntev dua qhov qub. Ntxiv rau qhov ntawd tom qab ib yam.

Kauj Ruam 1: Disassembly ntawm Pob

Cov neeg tsim khoom ntawm cov pob no ua rau nws tsis yooj yim sua kom tshem tawm cov pob yam tsis tau paub. Yog tias koj saib ntawm daim duab saum toj no koj yuav pom cov kua muag zoo li cov ntsaws. Muaj 2 ntawm txhua sab npog 2 ntawm 4 tus ntsia hlau tuav txhua sab hauv qhov chaw. Ob sab ib sab thiab sab saum toj thiab hauv qab sib sau ua ib pawg thiab koj tsis tuaj yeem tshem cov plugs yam tsis tau xaiv lawv lossis rub lawv tawm. Thaum koj hloov pauv lawv nws pom tseeb tias koj tau sim lossis ua tiav hauv kev qhib pob. Tsis tas li, pob siv #10 tamper pov thawj torx screws. Lub roj teeb muaj 2 qhov rov ua dua tamper pov thawj torx screws uas me ntsis yuav tsis ncav cuag yog tias koj xav qhib lub plhaub them nyiaj koj xav tau #10 tamper pov thawj torx ntswj ntswj.

Tsis muaj cov ntsia hlau nyob hauv daim ntawv lo ntawv nyab xeeb rau hauv qab ntawm pob, yog li nws tsis tas yuav tsum nqa daim ntawv lo. Tus lej ntawm daim ntawv lo yog E206252. Tus lej no tsis yog pob ntawv tus lej ID nws yog daim ntawv lo tus lej ID. Lub pob yog S12020a 20v Scotts sync roj teeb.

Lub 18650 plug -in phab ntsa roj teeb them nyob rau sab saud sab saud thiab cov liab thiab ntsuab dhia tau siv los them tus kheej ntawm txhua lub cell thiab kuaj lub pob. Them tag nrho, tsis muaj dab tsi ua haujlwm. Lub charger kom raug tsis kam lees lub pob thiab cov khoom siv yuav tsis ua haujlwm. Ntxiv rau qhov ntawd tom qab.

Kauj Ruam 2: Daim Duab Circuit Board

Muaj qhov txiav tawm me me uas pom hauv daim duab yav dhau los. Kuv sim hla qhov kev txiav tawm nrog xaim thiab tsis muaj dab tsi hloov. Tom qab ntawd kuv hloov lub xaim nrog 68 ohm 1/8 watt resistor thiab lub roj teeb them nyiaj yuav mus rau hauv "kuaj lub roj teeb" hom, tab sis tsis kam ua ntxiv mus ntxiv. Lub pob tseem yuav tsis siv lub cuab yeej siv. Kuv siv tus tiv thaiv vim tias kuv raug liam ua ntej tshem lub rooj tsavxwm uas lub cell tsis ncaj qha tsav lub cuab yeej. Ib tus tiv thaiv me me thiab lub diode xav tau txhawm rau txhawm rau cuam tshuam cov transistor Circuit Court uas tig lub roj teeb.

Los ntawm hauv qab koj tuaj yeem pom tias lub roj teeb zoo tang muaj kev sib txuas ncaj qha rau qhov kawg ntawm cov xov tooj ntawm tes. Qhov tsis zoo kawg dhau los ntawm kev tswj hwm los ntawm ib khub ntawm dc-dc mosfet hloov pauv MXP 4002AT TO263 2L.

Cov no yog cov tswj hwm qhov ntws ntawm pob. Lawv kib. Kuv hla cov mosfets thiab kub xaim cov pawg thiab sib npaug ntawm cov cell ib tus zuj zus, tom qab ntawd khiav lub pob hauv lub tshuab cua tshuab rau li 1 feeb. Cov hlwb mus deb ntawm qhov sib npaug sai.

Kuv txiav cov hlua txuas nrog cov cuab yeej siv lub tshuab txiav tawm ntawm tes (Dremel yog tias koj nyiam lub npe ntawd) tsis txhob siv cov ntsiab lus tsis ntxaws 6 ntawm lub rooj tsavxwm. Koj yuav xav tau rab phom siv lub tshuab ua kom siab thiab lub lauj kaub laug yog tias koj xav tshem lub rooj tsavxwm kom zoo. Txiav lub rooj tsavxwm tsis txiav cov cell sib nrug.

Kev hla dhau lub rooj tsav xwm hauv Circuit tshwm sim ntawm cov cell mus los ntawm 4.05v thiab 4.09v rau

3.75, 3.88, 3.90, 3.91 thiab 3.94 hauv li 1 feeb ntawm lub sijhawm ua haujlwm. Qhov kev txiav tawm hluav taws xob tsawg Samsung pom zoo yog 2.5v, uas yog qhov zoo nkauj heev. Feem ntau cov hlwb ntawm hom no yuav tsum tsis txhob ua haujlwm qis dua 3v Siv lub Turnigy watt meter, Kuv ntsuas qhov kos ntawm 320 watts ncov/25 amps ncov thiab 260 watts/15 amps khiav nrog pob poob los ntawm 20.75v txog 15v thiab tuav rau ntawd. Lub pob hluav taws xob tau rov zoo li yuav luag 20v tom qab tso nws so ob peb feeb. Qhov ntawd txhais tau tias cov hlwb raug thawb hnyav dhau thaum tso tawm ncaj qha.

Kuv tau sim them lub pob raws li txoj hlua thiab 3 lub zog muaj zog tshaj plaws ntawm tes tau nce ntau dua 4.5v, thaum ib tus tsis kam nce siab dua 3.6. Mus dhau 4.2v tsis muaj kev nyab xeeb thiab yuav phaj tawm cov hlau lithium hauv xovtooj ntawm tes thiab ua kom puas sai heev.

Kauj Ruam 4: Tsis Muaj Chaw Rau Kev nthuav tawm ntawm tes

Nco ntsoov tias txhua lub xovtooj ntawm tes tau kaw nruj nreem rau hauv lub plhaub yas. Qhov no ua txhaum Samsung txoj kev tshaj tawm kev tshaj tawm tias muaj chav rau 10% nthuav dav rau tus lej rau hnub nyoog thiab cua sov. Cov pob ntawv qub tej zaum yuav ua haujlwm zoo rau cov khoom siv uas xav tau 5 lossis 10 amps. Lub roj teeb uas siv hluav taws xob tua hluav taws los yog lub tshuab cua tshuab nplooj yuav tsum muaj pob ob zaug qhov loj me, tab sis qhov ntawd yuav raug nqi ntau heev nws yuav tsis muag.

Ob sab ntawm lub roj teeb yog ob npaug pluaj pluaj txuas nrog 4 qhov chaw. Koj tsis tuaj yeem txuas cov cell nrog kev tiv thaiv sab hauv ntawm qhov anode, yog li txawm tias cov xov tooj tshwj xeeb tsis tau paub, koj yuav paub tias cov xov tooj tshwj xeeb no tsis muaj nqi sab hauv lossis tiv thaiv kev tso tawm. Yog tias koj khawb cov pob rau cov cell, koj yuav tsum tau ua pov thawj tias cov cell no muaj ob qho kev tiv thaiv thiab tiv thaiv kev tso tawm.

Lub tsheb loj loj pib dhia pib siv cov cell zoo li no. 6 ntawm lawv, peb ntu los ntawm 2 qhov sib npaug yuav yooj yim muab qhov hluav taws xob thiab amps xav tau los txhawb lub tsheb nrog roj teeb tuag. Nws yog yam txaus ntshai xav tias koj tuaj yeem dhia pib lub tsheb nrog qee yam uas haum rau hauv koj lub hnab tsho. Kuv pib xav kom nicads tsis ploj mus. Cov no tuaj yeem yooj yim daws qhov tuag luv thiab them ntau dua yam tsis muaj kev pheej hmoo ntawm hluav taws cov roj teeb lithium no muaj.
