I just measured it, they seem to be 2.5 mm. I measured across 10 pins for accuracy. It looks like a JST connector. It even has the small retaining tabs like the XH series. I am looking in a DigiKey catalog and comparing the pictures of the connectors.
The lower first 14 cells is a 15 pin. The upper one is an 11 pin.
So it looks like we need an XHP-11 and an XHP-15 housings. The temp sensors are on a 4 pin. I think it is the same series.
Then we need the pins. I am only using 16, but I will order at least 30 to have a few spares. They normally come on a reel but they will sell small quantity. There are 3 possible pins. Standard ones are Phosphor Bronze with tin plating. Gold plated has to be special ordered. I think the pin we want is part number SXH-001 T-P0.6 which is the standard tension for 22-28 awg wire.
I can find pins on Amazon, but not the 11 and 15 pin housings. I think I want to get name brand quality, and not the cheap copies. The pins in the BMS do not look like gold plating, so the tin plated is probably the right way to go.
