We use megalugs, made by Spectro Wire and Cable.

and the "Hex Crimper Sr" from the same company to install them.

We use the anderson connectors from
http://www.powerwerx.com/
and reuse the plastic housings, buying new contacts for them.
We use the "Hex Crimper Jr" from Spectro to crimp these contacts on.
Heat shrink the battery lugs, but do not heat shrink the contacts for the anderson connectors.
Heat shrink will keep the contacts in the anderson connector from making good spring loaded contact.
If you want to get good reliability from a lesser setup you have to tin, crimp, and then solder, as mentioned by other posters.
As an added note, we replace the connector on the backup battery with the miniature power pole connectors.
The connector on the backup battery can be intermittent and this can cause problems with your robot controller.
You can keep this from happening by replacing these connectors with the miniature powerpole connectors that provide a positive spring loaded contact.

The 15 amp version of this connector is what you need for the backup battery.
Have fun,
