12 volt lithium 100ah battery charging from cigarette lighter. Can i do it?
It all depends on the voltages on the cigarette receptacle and the Lithium battery voltage. Different Lithium batteries have different voltages, so you need to measure some voltages or you might charge the wrong battery. Also if the voltages are a lot different the Amps flowing may be too much for the fuse on the receptacle and blow the fuse.12 volt lithium 100ah battery charging from cigarette lighter. Can i do it?
I will post a picture of my equipment. Maybe that will helpRemember, i am writing in the Beginners Forum! I dont want to reduce the car to ashes. Anyway, i am not using the battery to run a fridge or anything like that. I just want to take advantage of charging it while I am driving. It is for a trolling motor. I will look at what the charger and battery say and see if it will work. The cigarette lighter, i think, in my situation might be the best choice.
Thanks joe
What easy options might I have?You have a 100 Ah battery and a 5A charger. One hour of driving will charge battery be 5 Ah. That's not much.
100Ah battery, Cig outlet may need 20 hours operation to supply 100Ah = too slow, unless your favourite fishing spot is very far...It’s all a little bit of Greek to me. But, i gather that the cigarette lighter is not a good option and that i should look for something else.

There’s a wealth of information and experience shared here on this forum thanks to the community!Thanks for the excellent advice and explanations. For the moment I can charge from the grid and will probably just do that. I just thought that this might be an option. It is also nice to understand what is happening there and to be able to try one of those other options mentioned should the need arise. Thanks for all the input

Just like I said earlier, Cig lighters are undesirable for multiple reasons. You need a hard wired DC-DC charger or accept the fact that charging will be really slowIt’s all a little bit of Greek to me. But, i gather that the cigarette lighter is not a good option and that i should look for something else.
