Edit:
(I found two BMS would you recommend one of the for charging only)?
Hey,
i have some questions about a selfmade Liion-Pack.
I plant to do it like i draw in the Picture.
Maybe if u would say it is better i would do an 4p?
Now the Problem is, where can i buy the Batterys?
Good: In the EU / Better: In Germany …and if it would be cheap then also Asia and CO.
I would be very happy if you could share an link
And the second problem is: (Yes i read the Post about BMS )
Which BMS can you recommend to charge the pack?
Would be also very happy about a Link.
And the most probleme here is how to bypass (I read that in a nother post).
Maybe someone have a link to a tutorial. or can draw a shema?
I am an electrician technician, but i dont know how i can charge with the BMS.
Do i only put DC-12V to it and the BMS do the rest? or do i need more V then the Pack has (22,2V)
Maybe important Infos:
Planned for the board is a SK3~200kv, X-Car ESC
I linger on the endless sphere forum for information such as yours. For cells, you can message tumich on the endless sphere forum to see if he has the Samsung 18650 25R. He is in the EU. Please check to make sure supplier is giving legitimate cells and test them when you get them to confirm capacity stated. The comments for tumich can vouch to his reputation.
you will need a charger that matches the cells voltage at full charge.
Lipo and some Li-ions are 3.7v nominal and 4.2v at full charge.
So, for 6s you’ll need at least 24v to charge.
12v will not work.
tumich only has very few selected cells - I bought many sanyo ga off him - it wont get cheaper than that! he rarely had low capacity high drain types though!
