Is there a Garmin filter to eliminate trolling motor interference on my display. I previously used a 1.5ah power tool battery to power the Garmin in my kayak, but I recently added a trolling motor and big 100ah lifepo4 battery so I switched the Garmin over to the big battery. Now i’m getting the interference. I’m hoping there is an easy solution so I can keep using the 100ah battery and stop bringing a 2nd smaller battery for the Garmin.
