Actually I am not even sure it is JST. Long story short: I have two devices that I have to connect, but they use different connectors (I am perfectly sure it is OK to connect them, one is a balancer cable for multicell LiPO battery, the other is a balancer board for a LiPO charger). There is an adapter board with male connectors, and a female plug. Unless my eye sight fails me, plugs on the board are 2 mm apart, pins in the plug are 2.5 mm apart. That suggests JST PH and JST XH connectors - but I am not sure. Can anyone comment? I can take another picture from the side if needed, just tell me. I am not convinced I will make one, could be I will just look to buy one, but I want to know the type first (to prove to some people they are idiots ;) ).
