THese things are HUGE and of no use to me whatsoever for my RC planes (even the biggest ones). The end of metal connector is covered so you can't even solder inside of it from that way. I will keep them in case I have a use for the house but that's it.
I should have researched better...oh well.I gave it 4 crowns because it doesn't come with the little metal plugs you push through the middle to hold the two sides together. This means sometimes when you plug it in it pushes apart. Better than 45 amp anderson power poles because whenever you plug your battery in it always makes a little spark. After repeatedly doing this andersons deteriorate and go bad. This one doesn't seem to suffer from this problem as much.This connectors are huge. They are triple size of standard Andersson connectors. Not for use in a Skywalker FPV, more like a car or something very big like 2AWG. I dont know where i can use this so they are already in the garbage bin.These are identical to OEM Anderson Powerpole conectors, if not actual OEM connectors. They work as advertised - a high strength, low resistance connection. Don't be fooled by the fact that they are not gold contacts, as even the OEM units do not use gold. The contacts self-clean when connected together.
