Good question. I have looked at the website and read the User Manual. Here's my thoughts. The Engine Gateway will give voltage readings. The Battery Monitor shows voltage, amperes and temperature (with an additional external temperature probe). I don't think the amperes is going to give me any real additional information. If I look at voltage, before starting, it needs to be 12+v. While cranking, it should not drop below 9.6v. If it does, it's a bad battery. When charging, it should read 13.5+v. For normal operation, that's all I really need to know. If I suspect a bad battery, I'd go for the battery tester anyway. It will fit into the NMEA 2000 backbone, but I don't know whether or how it would display on the Garmin EchoNap. And finally, at a cost of $189, I'll pass on it due to the limited information it gives. The battery tester at under $100 is my preferred route.
As a Switch owner, we never hit the water without our mini-jump pack! It’s unfortunate that Sea Doo sells our boats with a sub-par battery set up.
Frank, would the battery monitor from Yacht Devices be something compatible with the Switch Garmin and your NMEA backbone?
