Given that I've read on here about Battery failures on the GS1250, I thought I'd see if there was anything on the market that would give me 'early warning' - and came across Gammatronix. I've just recently fitted one of these to my 2019 R1250GS Exclusive TE, and have to say it does everything it says - visible charging condition when the engine is running, battery condition when its not (and it flashes so looks like an alarm light). All I had to do was make a bracket (although you can zip tie it in place) and connect across the battery. Very impressed for the price and hopefully will give me early warning if ever I'm unfortunate to suffer battery issues.
