bassfighter Posted June 27, 2017 Report Share Posted June 27, 2017 Can I use the wire on a Jumper Cable to hook up two 12V Deep cycle battery to create a 24V system for Trolling motor? For years , I have been using Jumper cable wire to connect the 12V Deep cycle battery to my Trolling motor. I was reading that I should use 6Awg wire for 24V system. I believe some Jumper cable wire are around 8AWG. How do I determine the gauge thickness on a Jumper Cable? Link to comment Share on other sites More sharing options...
dheitzner Posted June 27, 2017 Report Share Posted June 27, 2017 I bought an 18" battery jumper cable from a battery shop: no issues. I'd imagine you could buy a short length of 6Awg and the end pieces (to hook onto the battery) for a few bucks if you wanted to do it yourself.

aplumma Posted June 27, 2017 Report Share Posted June 27, 2017 Marine Grade: There are several types of "Marine" wire. It's usually rated for a higher temperature and "wet" (think submersed) applications. it is also has a requirement that it be "self-extinguishing". That is extremely important on a boat in the middle of nowhere. SGT-M is SGT battery cable rated for marine use and is only a little more expensive than SGT. Some marine grade wire is "tinned" (plated) to help reduce corrosion and has a high strand count like welding cable. it can get very expensive (twice as much). If your boat catches fire and you go for a insurance claim it will be denied even if you use 6 gauge wire and it does not have the (M) rating for marine on it.

BillM Posted June 28, 2017 Report Share Posted June 28, 2017 (edited) I've always used a jumper cable with some crimped ends on them in our 24V setup.. Never a problem. Edited June 28, 2017 by BillM Link to comment Share on other sites More sharing options...
dave524 Posted June 28, 2017 Report Share Posted June 28, 2017 Be careful there is a wide range of wire quality and size in jumper cables, they go anywhere from 20 bucks to over a hundred mainly because of the grade of wire used. Link to comment Share on other sites More sharing options...
NANUK Posted June 28, 2017 Report Share Posted June 28, 2017 Jumper/booster cables will do the job, but it's not the proper choice, Most jumper cables now are made out of copper clad Aluminum ( read the box ), only designed to give a momentary boost, and save money, not good for prolonged load application like trolling motor etc, I don't even trust them as booster cables, I would use a proper marine grade cable of correct gauge for the trolling motor.

Sinker Posted June 28, 2017 Report Share Posted June 28, 2017 Yup, just go get the right cable. Any automotive/battery/marine shop will have it. Probably cheaper than booster cables too. Look in the car audio section. Link to comment Share on other sites More sharing options...
Smokercrafty Posted June 29, 2017 Report Share Posted June 29, 2017 Find any heavy truck dealership, ask for battery to battery jumper cables. Pre-made and already the perfect length. Also come in black and red to easily distinguish. (I'm knowingly saying this, only cuz my dealership sells them) Link to comment Share on other sites More sharing options...
Pikeslayer Posted June 29, 2017 Report Share Posted June 29, 2017 The whole concept of using jumper cables as a permanent solution is a little too redneck for me And I've been known to incorporate some redneck temporary fixes from time to time Link to comment Share on other sites More sharing options...
kenzy31 Posted July 2, 2017 Report Share Posted July 2, 2017 Car audio 8G power wire. $2 per foot here in Barrie for the nice soft, good quality stuff. The previous post about jumper cables being copper clad aluminum is spot on. And more expensive! lol I just wired up a new Motorguide and glad I went this route. Thanks to the members here for the help in battery choice too, I'm very pleased I came here for advice Link to comment Share on other sites More sharing options...
