I have a NW2 with a Sierra sound board in it. I have been using a rechargeable 9volt battery to power it on my track powered RR but it does not always work. I thought about putting in a bank of super capacitors to give it constant power with no drops over sketchy track. I have a GP with a Phoenix that I bought used and it performs nicely. I don’t know what type of battery is in it but it recharges from the track.
I bought a super cap setup for the Sierra that is used by the Revolution system. Did I make a mistake here? The caps are rated for 25v 3300uF. The plug is the same on the super cap setup and fits the Sierra battery input plug but I think they are too powerful?
The bigger question is if not super caps then what type of battery for the Sierra board?
My understanding of electronics is amateur. I can install things but I can’t build boards and circuits etc…
Any ideas? Thanks.
