If you do not already have provisions in the boat for a battery selector switch, this needs updating.
BEST BATTERY JUMP STARTER FOR BOAT FULL
This is perfect for a full day out, listening to tunes and running any DC circuits. They have the best survival in the area of draining and recharging over time. I would suggest adding that 2nd battery with a true deep cycle. Jump boxes are really considered an emergency and not part of the normal week out process.

You are asking a good question and this is an important area, especially when the normal plan is to put a load on the battery for the day. I can't imagine this being a regular thing, particularly as we figure things out like "we should idle the engine for 10 minutes every hour" or something.ĭoes picking one of these up seem like a good idea, or should I just do my ACR and second battery plans? What's a good best practice for how often to run the engine to keep enough charge to start it while letting your stereo play while beached? Is there any reason to think that this wouldn't be just as good of an "oh shit" backup plan as installing a secondary battery system? My primary concern is not being stuck out on the lake if we accidentally run our battery all the way down, which could just happen on accident as I have no idea if we can run the electronics for without the engine running before getting into the danger zone. We were wandering around Costco today and saw this portable power bank that is also made to jump start most cars and trucks for $70. I'm thinking that an ACR and the second battery is probably going to easily run me around $300 (or more) to add.

BEST BATTERY JUMP STARTER FOR BOAT INSTALL
I've been doing a lot of reading, and it seems like a common thing that people do is install a second battery with either a manual switch or an ACR to not need to micromanage which battery is connected when to always be sure you've got enough juice left to start the engine. Right now I don't have any concept as to how long we can run the house electronics (stereo, Humminbird Helix 5, and potentially navigation lights) while still having enough juice in the battery left to start our engine (Mercury 150 Pro XS).

We're new pontoon boat owners and I'm still figuring out a lot of stuff, so apologies in advance if this is a stupid question.
