I think these are a generic connector and a few companies make/made them.
Is yours 8mm pitch and the pins are 2.36mm/0.93" diameter?
If so JST do a series called [
JST LV]. The manual with part numbers is [
here].
The two pin housing is 2P-LV. I can't see them popping up at RS for example from a quick search though, maybe have a look around.
If you get really stuck I think I have some 5 pin versions of these that could be cut down to 2 pin. I would just need to see if I have contacts too.
