ridgid 24 volt tools are no longer being produced by ridgid, so your expensive tools are going to be worthless, as home depot quit buying them from ridgid, so ridgid quit producing them for this reason, you can not even buy this saw from ridgid to expand your set if you do not already have one, try and buy a 24 volt ridgid circular saw or even the max select 18/24 circular saw, so i guess your set, like mine will never be expandable, your stuck with what you have unless you buy a used one or new discontinued one from ebay or a site like that, but remember you can never register it for there great life time warranty.

below is the reply directly from ridgid tools

The line was discontinued. When Home Depot does not order the tools, they are taken out of production as the Ridgid tools are sold only at Home Depot. ALl items are sold direct to Home Depot, we do not have any stock of the tools.
