@Mikev22 posted:Thank you everyone who answered my questions I’m going to go with the ERR sound board last question the 9 volt battery for the conventional use could it. Be a BCR or does it have to be a regular 9 volt battery
The commonly available BCR is not an option for these as the RS-Lite board doesn't have a charging circuit. If you want low voltage operation and sound continuity on direction changes, there is one permanent option to replace the primary battery.
The YLB - RailSounds Battery Replacement (RS-Lite) replaces the standard battery and maintains it's charge from track power as low as around 6 VAC. This unit plugs directly into the ERR RS Commander board and has one wire that connects to the center roller track power.
