Wow! Just got the new version of the VX231 (VX231-G7UNEP) and I love it!! Upgraded battery was totally worth it. I also have some other Vertex radio models and now the charger works with the other Vertex radios I have which is a big plus. Unfortunately, the new charger doesn't work with my older VX-231 radios but I had to order new batteries for those anyway so the new battery versions I got will soon work with the new chargers too. Gigidy!
