How to make 3s 14p li ion Battery Packs 4K. 18650 DIY.

[@tamersayin3638]

Etkileyici bir çalışma, kutlarım. Videonun sonunda görülen şarjlı süpürgenin pil değişimi videosunu da görmek isterdim.

DIY wykonanie i zgrzewarka sa super. Jedyne co moglbym dodac to obudowa z twardego materialu bo tasma moze sie latwo przedziurawic. Pozdrawiam

[@danielw855]

Dzięki za komentarz. W przyszłości możliwe, że dorobię jakąś obudowę. Aktualnie pakiet jest używany z panelem solarnym (bateria nie jest narażona na przemieszczanie się). Dla bezpieczeństwa gdy, nie używam ogniw to umieszczam je w skrzyni metalowej na amunicję. Pozdrawiam.

recuerden de que este es un video de como no hacer baterías los grupos de celdas se deben de aislar de alguna manera ya que si el forro de ellas se rompen entraran en corto entre si ocasionando un incendio

[@JuanPerez-jh9lj]

Muy buen video,podrías enseñar,como hicistes el soporte para sostener las baterías,por favor.

Great job with all the best information and helpful

I don’t understand why you chose to split the groups the way you did at 3:42? It looks like you’re making TWO BATTERIES. Each is a 3S7P. Then connecting those two batteries in parallel to get 3S14P. Is my summary correct? It’s hard to follow the jumpers you add later. If you are indeed making TWO 3S7P batteries, then all of your hard work to use “repacker” to obtain capacity matched 14P groups is wasted. Your 7P groups will not be capacity matched. Why not simply put all 14 cells in group 1 next to each other in a 2x7 arrangement? Then repeat for group 2, and again for group 3? It simplifies your jumpers and guarantees each group of 14 cells stays together…. Which means they will be perfectly “capacity matched.” Another note, at low currents your configuration is fine, but at high currents you’ve got ALL THE CURRENT going through one tiny piece of nickel strip. Probably should double or triple the 0 Volt and 12.6 Volt terminals. Also, for your BMS… tap into the ground and 12.6 Volt terminals at opposite ends of the battery instead of the same end.

[@danielw855]

you misunderstood, the battery is calculated correctly.

Fixing BMS is my favorite part

[@commandant30]

Hello, I have a question regarding this same BMS please, if I want to draw like 15-20Amps, should I use balance wires that can carry this current, or maybe is it possible to use small sense wires and in same time connect a thick wire from the main negative and positive of the battery to the discharge terminals??

[@keith_ferdinanduz]

Actually, if you use 3S BMS Board you don't need thick wires at 4.2V and 8.4V points. But you do need thick wires at 0V and 12V points, as well as charge/discharge terminals.

[@commandant30]

@@keith_ferdinanduz Thank you Keith, I already used thick wires on all the terminals. my question was for learning purpose. I appreciate your help

You probably shouldn't do this.

[@rasheed-ameen]

Thank you. Can you explain the charging and what is the optimal charger?

[@danielw855]

IMAX b6 mini. 12.3V - 12,6V ; 5A. My battery is being charged by a 100W solar panel.

[@dentaldirekto1433]

Shouldnt you be isolating the cell groups? if any of these individual plastic sleeves tears or wears down it will catch fire in no time....

[@danielw855]

It was a test package. I built a new one

Hi DanielW, I liked your piece and tried to copy it, but I have a couple of problems. After assembling it I recharge it at 12.5v, 2.5Amp. After 5 hours I reached 12v but the side closest the BMS heats up a little and the voltage is not ordinary, I have 3.50 7.8 11.77 instead of 4.2 8.0 12v as written in the BMS manual . I made a mistake or...?

[@danielw855]

It is possible that one of the links is damaged or poorly welded.

[@jacekpiasecki7059]

Przemyśl sposób zgrzewania ogniw. W połączeniach szeregowych między celami 1S->2S->3S płynie pełny prąd obciążenia pakietu. Tutaj taśma musi być gruba, a połączeń wiele. Wszystko dopasowane do maksymalnego obciążenia pakietu. Dałeś 3 paski taśmy na 40A (do tylu pozwoli obciążyć ten pakiet zastosowany BMS) - to zdecydowanie za mało. Połączenia równoległe między ogniwami tych samych cel są praktycznie nieobciążone prądowo, mogą tam płynąć prądy wyrównawcze poszczególnych ogniw. Można ten fakt wykorzystać i dać taśmę cieńszą lub tylko niklowaną, zamiast czystej niklowej.

[@danielw855]

Dzięki, wezmę to pod uwagę. Aktualnie pakiet pracuje z prądem do 5A max.

Hi, isn't it a problem to use different cells in one package?

You need to choose them appropriately using the 18650 calculator.

Marka baterii jest inna na filmie, czy to problem?

[@danielw855]

Firma jest bez znaczenia. Liczy się pojemność oraz, rezystancja wewnętrzna baterii. Osobiście dobieram tylko pojemność, korzystam z kalkulatora do tworzenia pakietów.

[@TF-pz9lp]

@@danielw855 Dziękuję Ci. Czy możesz udostępnić kalkulator. Tymczasem pozdrowienia z Turcji. jaki powinien być zakres pojemności baterii

[@danielw855]

@@TF-pz9lp W kalkulator wrzucasz wszystkie "akumulatorki", które posiadasz a program Ci wszystko obliczy. Pojemności akumulatorków piszesz po przecinku, tak to mniej więcej ma wyglądać: 2074, 2038, 2104, itd. Klikasz "Add Cels" w kolejnym okienku "Number of cells in series" - wpisujesz jaki to ma być pakiet dla 2s wpisujesz 2 dla 3s wpisujesz 3 itd. w okienku "Capacity" wpisujesz ile chcesz równolegle połączonych akumulatorków np.: dla pakietu 3s10p będzie to 10. Klikasz "generate pack" w prawym górnym rogu klikasz suwak "compact" (zmiana sposobu wyświetlania bardziej czytelnie). Również Cię pozdrawiam. Link: www.repackr.com/#/pack-builder
