Calling all battery builders
You simply add the cells to those single rows however if you donât u derstamd how to add parallel cells I wouldnât advise to go out and build a battery, have someone do it for you or read some more
You connect the 20 batteries into parallel and then you will have 10x 2p packs once that is done you connect the 2p packs into series to give 10s2p. The balance leads go onto all of the series connections I believe
youâre going to need blood. A lot of blood. And a transmutation circle.

haha thanks for the input guys 
i understand how to wire cells in series or parallel, no problem. what i dont understand is
-
in a 1p obviously each cell can be measured individually through the balance leads. but in a 2, 3 ⌠550p
how does that work? i join two cells in parallel an just have them use the balance leads together? -
if i wanna make a really flat pack, so lets say 10 x 2 next to each other (not stacked on top), how do i go about seperating them, so they dont short on the poles when the two rows are lying ânext to each otherâ? just a bunch of isolating tape?
hope you understand what i am asking here hahah cheers guys
-
Yes the two cells just use the one balance lead
-
You can use whatever you like eg. cardboard, tape, rubber or foam. Anything that is nonconductive
Maybe some battery builders can let you know what they use

Hey so i was thinking ⌠a 7S3P would still be better than a 10S2P?
1000W / 25.9V (7S) = 38.61A 38.61A / 3 (3P) = 12.87A per cell
Is this thinking correct? The 10S BMS on alien systems is sold out for a while, thats why i am looking into other options. Are there reasons why a 10s2p would still be preferred over a 7s3p? The cell count only differs by 1 cell âŚ
I have this small BMS but i donât have tested yet http://e-greenmotion.com/index.php?route=product/product&path=111_128&product_id=288
Interesting! Cause that one also has a switch and a cable for LED indicators ⌠Do you think they are shipping from within Europe?

Yeah its a very small bms included the switch and led indicators cable . Iâam from belgium but i have orderd from them with ebay but they have stopped selling on ebay. You can send them a mail, they answer very fast
You could get these, they look good! https://eskating.eu/product/10s2p-eskating-electric-skateboard-battery/ https://eskating.eu/product/7s3p-eskating-electric-skateboard-battery/
its true thats a pretty cool offer. only thing is that id prefer 30q cells over 25r and i kind of wanna take the challenge and build my own battery pack
Itâd honestly be cool if you make it yourself! Iâm just scared since I think itâs the most important/dangerous part and I just donât trust my hands(( Do you have any tools? Spot welder, soldering iron?
Yes i have a 100w soldering iron
