for 12s4p is 135mm wide and 550mm long and 22mm tall from bootom pcb. is size might change bit.
Thank you friend. Please vote help choose make first. we make choose after tomorrow. PCB have 4 layer with via for good current and safe. we make good price once confirm.
635mm long, which deck are you thinking of using to fit this under?
This.
Very few decks can even accommodate 12s4p in a single stack configuration.
You can also reduce the space in plastic spacers. Are those 3D printed or do you have a mould/mold for that?
Can the cells be put in this format? Mine is 10S5P, but can easily be made 12S5P.
I think it will reduce flexibility
I honestly don’t think you can sell many 12s5p PCBs.
Even spot welded battery packs with no dead space are still too big for most decks and enclosures.
There are a few that can fit such a pack but in my opinion once you go past 4p you should look into double stacked batteries.
We fit 50 cell to evolve carbon gt with pcb. Is 10s5p.
Hello friends. Is clear 12s4p is want by people. Engineer start making layout tomorrow. We plan sell for $60 but offer to first 20 friend for $50. Is 4 layer pcb for handle lot current and come with new cell hold that make easy align nickle for assemble. Is make compact for easy fit.
If interest let know. We make price fair for what cost make. Is big pcb with 4 layer and lot copper. No cheap make.
Can be ready next week.
I’m down for 1.
12S4P
Is compact for neat fit. 4 layer 2oz copper. Can have high current. Have xt60 connect and solder for bms balance.
Start making this week.
We do final testing then start produce tomorrow. Can friend help with english word for instruction. Want make safe for friends install be sure. PCB can manage 75A current max.
I sent you a pm with some rewritten instructions.
Thanks you friend! Very much help.
Thanks for help with words. We start make PCB today with factory. Is ready 4 days. If want please let know as we make limit pieces for starting.
