Attaching battery clips for a small accessory

Factual Questions
1

I have a tiny row boat that fills up with rain water more quickly than my arm recovers from bailing it. I purchased a little submersible bilge pump that connects to my marine battery and empties the water at tremendous speed (600 gph). It is a joy to behold.

Unfortunately the gizmo comes only with tinned wire ends - so I’ve had to strip a little extra to form a loop to put over the battery terminals. The little gizmo is so enthusiastic that it pulls itself off the terminals at regular intervals.

I got some small battery clamps to attach to the wire ends, but I don’t remember enough science to know if I’m making a mistake trying them. The bilge pump has an operating current of 3 amps. I bought 10A alligator clips.

Am I going to break my gizmo? Will anything blow up? Is it safe to use?

Thank you for your wisdom and knowledge.

Sure, it’s safe.
But, the should be NO strain on the leads - if there is, the wire will eventually fatigue and break. Try to restrain your little-pump-that-could so that it doesn’t tug on the power leads.

Will do - thank you so much. It’s such a happy little thing :slight_smile:

Pictures!

Could you beach it and repair the hull? I don’t doubt you’ve thought of that and perhaps it’s more than you can do. But… You did say tiny row boat.

Use zip ties to hold the leads on the terminals? Wire fatigue is probably an issue still though, maybe get creative and use some PVC pipe and mending plates to fashing some sort of stabilizer (only cost a couple bucks and 20 minutes) That being said, my mother’s basement keeps getting flooded, maybe I’ll pick up one of those instead of slow sump pumps. Where did you get yours? What brand? Thanks!

Soldering them would be a good idea. And don’t forget the heat-shrink!

It’s the Shoreline Marine Bilge Pump - good for fresh or saltwater. I believe the model is SL52256.

It’s tiny but mighty and costs very little. It’s my favourite thing as we’re getting more rainy days than sunny in Ontario.

There is a way to anchor it so that it won’t bounce around and compromise the connection. I’ll get the water out one more time and secure it in place.

I have a couple pieces of equipment that bounce around a bit and use battery clamps for the connection. I just make a loop from the clamps and put a piece of duck tape over them on the body of the device. All the strain is at the duck tape. I have to peel it off when I remove them, but that’s trivial. I can still disconnect a clamp to power the unit down without removing the duck tape.
