12v and 24v Onboard Chargers. Separate Cords?

[Bucks Bass and Bourbon]

For you guys running a separate plug for your 12v onboard charger and a 24 or 36v charger - how do you run your extension cords? Do you run a single extension soon plug with a splitter (or a multi plug cord) or do you run two cords and keep them separate? I would like to keep it to a single heavy duty cord with a splitter if it’s safe.

1 110 AC power chord to the onboard Noco 10X ( number of batteries). The onboard charger has a separate charging cord for each bank to each battery..

It’s safe assuming you’re not running a 200ft cord or using a 50 amp charger.  I run a single heavy cord that powers both of my chargers.   The battery chargers that most fishermen use do not use that much power.

Nope a 50 ft cord to the 12v that has three 15 amp banks (two used) but the 24v charger is a 20 amp.

Well that could pull in the neighborhood of 900 watts worse case if my math is right. Do you need a 50 foot cord?  If so make sure it can handle 1000 watts or around 10 amps AC.

The times I would need a 50 foot would be when I’m staying overnight and I need to reach to an outlet which I do frequently enough that it’s a concern. The rest of the time the boat is in the garage and I can use shorter separate cords. The heavy duty 50 foot cords I’m looking at can handle 15 amp/125v/1875 watts so sounds like that would handle it, no?

Yes I think you’re good with that.

One 12ga drop cord would run both chargers.  The main problem I see you running into is the diameter of the drop cord.  If you are RON at a dock, there should be no problem but if you are RON at a motel most of the time you have to plug in inside the room and getting the door or window you have to go through to outside closed can be a problem.   I had a flat, three conductor 12AWG drop cord I used but it always scared the hell out of me because there was no buffer/filler layer in the wire.  For a #12 wire, it was extremely thin but if you happened to get a nick in it, you were seeing exposed copper wire, so I inspected it regularly.  

 

You also have to remember, it's only in the bulk charge mode that the chargers are pulling max current, which is usually not very long.  On most good chargers, once you get to 80%, they are out of the bulk mode and are pulling much less current.

Thanks again for the input guys!

I had a single bank and 3 bank charger in my Lund. I installed a splitter under the deck so I only had to run 1 extension cord for charging
