Anderson Plug

You can get them alot cheaper than $30. The 50A is a one piece connector with 2 contacts. From RS components in Sydney the housing is $4.71 and the contacts are $2.10 each, total price $8.91. The 75A connectors are very similar to the 50A except they are a 2 piece and you can slide them apart, when together they are a slightly different size to the 50A and won't fit as the 50A has it's contacts wider apart, but if you slide the 2 apart, each 75A connector will plug into the 50A. These are $3.32 for each connector and use the same contacts as the 50A at $2.10, total price $10.84.

Web site is www.rs-components.com.au
part numbers are:

50A housing 290-6124
75A contacts 290-6118 use these in 50A housing as well
75A housing black 290-6152
75A housing red 290-6168

The 50A housings come in grey and red, they are very similar but they won't connect together, the grey one seems to be what most people use.Just put the part numbers in the search field to find them.
I really don't understand how places charge $30 for these. It's not like they're different quality, they all come from the Anderson connector company in the USA.
