I am gearing up to making my own Beo5 replacement battery. I got the batteries and would like to solder a new (?) jst-3pin connector, rather than using the old one. Does anyone know if this is the right connector and which size it is. I have not (yet) opened the remote, but have read all the blogs/forums and ordered the batteries from Germany, as I have trouble finding those here in the US. Any info is appreciated. Thx in advance
