I've got a couple of 8S 100A JBD BMS's that I've been happy with (actually, three now that I think about it). The JST connectors on these boards (purchased several months ago) are 2.54mm pitch (0.1"), including the 4-pin port for the Bluetooth or USB connector. I have Bluetooth transceivers for all of my boards, and I bought a single USB transceiver a while back to allow me to calibrate the cell voltage sensors, as they seem to be always off by a bit.
Fast forward and I now have four additional JBD 4S BMS's. Two are 80A rated, and the other two are 150A rated. These are the newer ones with the M5 terminal pads vs the previous 12AWG wires coming off the B- and C- pads. Unfortunately, it appears that JBD decided to "improve" their board interfaces, so now the Bluetooth / USB TTL transceiver interface is a JST 2.0mm connector, with a specific latch mechanism that I can't identify. I'd like to use my same USB interface to calibrate these BMS's, but I can't figure out what connectors to buy. Does anyone know how to describe these connectors? Aside from the fact that the are 2.0mm pitch I don't know what to search for. I have some other JST 2.0 plugs and they won't fit because of the housing.
Any help would be much appreciated.
