does a Kinetik battery really make that much of a difference?

[NightScreams 10+ year member]

Although I've done the big 3...etc, never put much thought into what type of battery I used until I saw this video: https://www.youtube.com/watch?v=HVYU_xb8l4Q

I usually buy fairly cheap batteries, right now my car is still pretty new and has the stock battery. Would replacing it with a Kinetic really make that kind of difference? I never had issues, no drops or dimming so figured my battery put out enough juice. I'm only using maybe 1150 watts worth of amps between the 2..rated that is. Have no clue what I'm actually getting output wise but I thought it sounded fine. Would a Kinetic be worth it for me?

Not always with that set up it have no clue just guessing, his battery was on it's last leg and he got a brand new battery so his amp had better current draw and most likely a higher voltage. If you see that your battery starts to die then I would however upgrade to an agm battery.

If you have no major voltage drops, dont switch it out unless your current battery's dead. Its only needed when you're dipping down to the low 12s and under. Besides, after going ham for a few minutes, your car is going start falling back to alternator supplied power anyways. If your alt's not up to snuff, your battery wont like it.

I am not OP but I'm askin a question

I have my HC2000 and I'm about to hook it up as a second battery but I have a stock alt and I am wondering if this will hurt either my alt or my battery. I don't have any voltage drop right now because I'm only running 1kw but I am putting it in there now so I don't have to later when I get my new amp.

normal wet cell starting car batterys will generaly rest at a lower voltage than a good agm battery will want to rest at. if you directly hook them together the battery with higher voltage will always keep trying to charge the battery with a lower voltage - and in turn the better of the 2 batterys will always remain at a semi state of discharge.

it is not the ideal way to hook it up - but people do it all the time - it will work - its not the verry best way to do it. ive done it in the past

the best way to add that battery to your car right now

is to install something called a relay

it can be wired to ignition hot. so when the key is off - the relay will "un hook" the agm extra battery from the front battery

but when the ignition key is on and the car is running - and alternator producing 14v then both batterys are hooked up together to power the car and system.

the other acceptable way is to remove the regular wet cell car battery from underhood - and replace with the same type of agm battery.

I am running the agm 65 under the hood so is that ok?

Here is what he is talking about. NVX BIR200 200 Amp Relay Isolator (BIR200) - Sonic Electronix

Personally I would use one if I were to use 2 batteries. I might do a second, very small one sometime in the future but really don't have the room. The real issue for me is they don't make H/O alts for Honda Fits, you have to get them rewound or whatever. But luckily it puts out pretty good amperage and so far no issues other than I listen to my music for 20 minutes at lunch hour on just the battery which gradually kills the battery after a year or two, So i'm gonna use a trickle charger every night to keep the battery fully charged since I don't drive enough to keep it completely full.

That would be a battery isolator, not a relay. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Looks like a relay switch to me. I think they are called both because a relay also isolates?
