Thread: Battery Jump Question

I've got a 24 volt trolling system. If I ever need to jump my cranking battery off should I decouple the two trolling batteries so I'm only jumping with 12v.

Yes you should, you dont want to send 24v to a 12v starter

You wont send 24 to starter if you connect jumper cables to one battery.....so no...you do not have to remove the connector cable between the two batteries.

Wrong, if they are coupled together + hooked to - any place you hook to is going to produce 24v you will have to uncouple them to get 12v

12-volt and 24-volt systems

So your telling me that I spent all that money on 24v lights when all I had to do was buy regular 12volt lights and only hook to one battery

That would be correct.

You only get 24 volts when you connect to the negative on one battery and the positive on the second battery on two batteries connected in series.
