I has every went to your car and the battery was dead or had the car in acc and the stereo killed the battery and the jumper pack I dead. I was thinking to wire a power invertor into the trunk and so when the car is on the jumper pack keeps a charge. And to be on the safe side add a toggle switch so you can stop the jumper pack from charging. So what you all think

I'm sure some idiot has. Get an extra battery installed in your trunk (keep in mind, it may need to be vented to the outside of the vehicle unless it's sealed) and wire up an isolator to keep it separated from the main battery. So, when the front battery goes dead you can flip the switch on the isolator, start the car with the rear battery, then flip it back to the front battery to charge it up. ------------- 2013 Kia Rio -90a alternator

True that can be done and I just redid my trunk and I have a spot for my jumper pack and sometimes I forget to charge it weekly but I never get stuck cuz I'm very conscience of my charging system and don't wana be chasing people with jumper cables or pay a towing fee. But if I get bored and end up gutting my trunk again ill throw a extrax battery in it

This would maybe be a good idea in a perfect world where the inverter and the battery charger were 100% efficient. But since neither of those devices are that efficient, the current drawn to charge will outweigh the amount of current provided. And no I have not tried it JMelton.

So what you mean you saying the jumper pack isn't reliable. How is the invertor not also. Not understanding what your getting at. Explain your input thanks

Why does your battery die so easily? Maybe you should try to fix this...

I don't have a charging problem issue I have a 240a alt a 800cold cranking 1000 cranking and the big 3 the car starts with no problem I'm aying in the worse case situtation. You pull out your pack to help someone and your pack is dead.

I saw a battery advertised someplace that had a built-in backup battery. I guess it had an isolator, then there was a switch to connect the backup into the circuit. I assume it would be a) more expensive, and b) would have less normal capacity than a normal battery the same size. Still, if you spot something like that at S-Mart on sale, it's the easiest solution.
Otherwise, hardwiring in a booster pack, assuming it isn't subject to overcharging, would be a nice way to go. Even if it isn't OK to leave hooked up all the time, you could wire up a relay (or two) to put it on charge (or make it boost) with just a switch on the dash.

Is this bass really strong enough?

You can do this with an extra battery and a heavy duty relay. Very simple...catch is that you can't jump the front battery too often and not for very long or the contacts of the relay will burn up

Why can't u jump it I'm saying to have it charge when the car is on have a relay or switch wired into the invertor so when its charged turn it off and if you need to use it unplug it from the plug from the invertor use it then plug it back up

no need for the inverter...while the engine is one the alternator would charge the battery...wire an on/off switch to the remote lead of the relay.
When the engine is off the rear battery would be isolated from the front...if you want to give it a jump just flip the switch give it a second and crank it...crank it too much and the relay will get damaged.
why would you need an inverter??? What does 120volts AC have to do with a 12 volt battery??

anybody else remember when you could understand what "still_walkin" was saying without rereading his posts three times? Are you ok dude? Your typing has gone way downhill in the past year or so. I was away for a while (thanks) and remember being able to understand you much easier. I am not trying to come off like a butt or anything, I am honestly concerned. Sometimes stuff like that is an indicator of health problems, or maybe I have been watching too much "House". As far as needing the inverter goes, Maybe the jumper pack that he uses only charges through AC. ------------- all bad things come in moderation. do not shop at fry's. Get your own log in Omar.

Maybe you are watching too much tv, and no need for the insults. I don't proof read someone of my post and usually when I'm writing these post I'm in traffic and I have the keyboard on my phone memorized but I make a mistake here and there. This is what I was asking. I was wondering if anyone has wired a portable jumper pack to the cars electrical system. The layout I came up with is from the fuse box or battery wire up a power invertor to the the jumper pack and install a switch so when the jumper pack is charged you don't have to unplug it. Someone told me to go with two batteries but I just redid my trunk and I'm not going to modify it to fit another battery when I already have a spot for my jumper pack. And no I don't have any isues with my charging system. The reasoning for this post is a just incase situation. So can one help me or has it been done thanks ------------- 1993 sdv

all a jumper pack consists of is a small sealed AGM battery in a case with two wires and clamps...why don't you buy a small sealed battery and just wire it up parallel to the front battery with a 200 amp HD relay. A lot simpler than messing with a jumper pack.
FrozeNutz what you are thinking about with an inverter to charge the jumper pack is like converting 120volts AC in your house to 12volts DC and back to 120 AC again.

Well I didn't know that. It seems easier but then I like to take the hard road sometimes thanks guys

As stated, I was not trying to be insulting. Trust me. It will be much more obvious when I am insulting, which the mods can verify (and then delete my posts). I have had friends that have developed serious problems, and the first thing that I noticed was in their written communication. I respect you as a person that uses this board for what it is for, and not just one of the lazy people that come on and ask "which onez better, the audiobahn or the power coustic" and then get wized when they are told that they both are crap. You are obviously here to better yourself as an installer, and as this thread has indicated, you are willing to help others out. I wish you the best of luck on your most recent project, and please keep us posted on the final decision. ------------- all bad things come in moderation. do not shop at fry's.
