I’ve been using these https://www.amazon.ca/gp/product/B01LCV8LVK/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
Seems to work well.
I originally installed with the standard jst connectors, but outside in the garden, the connectors corrode badly (although they do last a couple of years). I have used dielectric grease, but they still corrode.
Right now I still have a lot of the original jst connectors in place, they are greased, and covered in a 3D printed ABS shroud, but I’m gradually replacing them with waterproof connectors - it’s slow going.
I would say the “automotive” connectors are not really waterproof - often they are waterproof at the front, but not the back. I have used them for power with silicone in the back, plus heat shrink over the wire entry, but I still have had pins disintegrate - outdoors is hard on high current connectors (outdoors in Canada anyway).
