But if you end up getting a decent price on the PCBs, don't mind me! Just a side thought...It's less integrated/automatic, but it's hardly more difficult to lay down wires in a groove and maybe add a drop or two of superglue. And 2D lasercutting for certain materials can be much cheaper.
Agreed, I can make as you suggested, but my intention it to make something that lasts, and is user friendly, with minimal effort to assemble battery pack. I'm not looking customers who are looking for a dirt cheap solution, rather customers who like/need clean and easy install.
Second point, i am making bulks, so getting better price on PCB, and if you would do it yourself, you'd end up paying slightly more and wasting your time on designing PCB etc. There are junkyard projects here on forum and I admire them for what they are and creativity people put in to them, but this is not it, and i pay extra for stainless bolts, brass and rose coating just to make it better. I did mine as you suggested with wires no connectors but its a pain, and a lot of time spent assembling the pack + more if one cell goes bad. This is eliminated on this kit and should make pack building a breeze.
Last point, if there were single configuration, say 12S, and 1000 kits ordered and paid the price would drop significally and there fore i cant buy stuff in large quantities and then make it if there is no interest, will end up bone deep broke and with kits to build electric jumbo jet
Short version - custom always cost a little extra!
Prices were above my last post, will repeat myself:
4S - 59.41USD
6S - 65.90USD
12S - 90.21USD
16S - 105.25USD
18S - 113.37USD
24S - 136.85USD
30S - 160.01USD
Cheers for suggestions thou.
