I will recalculate and post prices as soon as i will get the invoice, prob. mid week. Connectors i got looks good, they are clip on so should stay connected, big enough to solder BMS wires to and small enough to fit I have ordered extra sets just in case someone wants them. Was going through layout, found an error, opening for cell tabs was .2mm wider than it should be, all fixed now. Had time to lay 16S board as well. All checked and sent out for manufacturer.
I will have 4 extra sets of 6S, 2 sets of 4S, 1 set of 24S and 2 sets of 16S (*NEW*) and 1 or 2 sets of 12S.

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.

Kin wrote:I'm not sure about pulling 100A, but one of the ways people pull higher loads without a bigass resistor is with banks of halogen lights. The halogen lights act as resistors, but also are heat sinking themselves by putting out some of that energy as visible light and projected heat.
I don't know how precisely to go about it, though, because the resistance isn't as constant as a resistor within parameters. Alternatively, for ~$15 you can buy (6) 100 watt resistors from ebay.
