He becomes the National League newcomers’ second signing of the close season.
The former Wimbledon and Forest Green striker has been backed to have another highly-productive season in front of goals.
New manager Darren Sarll has given the 28-year-old a two-year deal and
Sarll told the club’s website: "Rhys had a very successful season last season and arrives with that hunger to do the same again.
“He's a fantastic finisher and will add that out-and-out goal threat to our squad and I’m looking forward to working with him.
“This club hasn’t had a 20 or 30 goal striker since the days of Paddy Madden, so I’m delighted to bring Rhys in as our new number nine."
