Did you find any good Ideas? I have an EchoMap Plus 93sv and a Panoptix transducer for my boat already. I want to put an ice bundle together with a lithium battery. I was thinking of using the 12V output from my lithium car booster. It is a 20Ah pack and should work well.

Just hoping to see more ideas here. I don’t want to spend $399 for a Garmin ice bundle
