Most folks buy 4S packs to save a few $0.01/wh at the cost of lots of build labor wiring it all together. Although one could use our boards with 4S packs it would be an inefficient use and the added cost would offset the savings you made buying 4S packs.
3 x 6S = 18S and needs three $50 parallel boards
4 x 4S = 16S and needs four $50 parallel boards
Just not a good match.....
Alternately if ones labor was not worth anything they could build a parallel/series harness to convert the (4*4)S2P into (6+6+4)S2P to use three boards instead of two....
Anyway -> I have 13 or 14 5S boards in stock, 3 6S boards in stock, and although I thought we had some 4S on the production line I think those got converted to 5S and sent off last week.
Parts have been ordered and we have enough PCB's to make about 50 more parallel boards. Once those are gone there will be a dry spell until I get the next version of PCB's finished and tested. This next version wont be much different from the users perspective - just more efficient from the production perspective.
