As I commented 4 months ago, this is a WAY stronger battery. But Id like to see you running THREE of those 370 amp alts, a single, cheapie AGM from Costco, and 4 super capacitor banks making 2000 farads. My goal would be to not have ANY voltage drop whatsoever ! Make more juice right from the start, than your setup uses at full tilt ;)

That would be nice

This dude is AWESOME!

[@KurtisPape]

Great video! You amplifier will thank you for being able to sit at 13.5v at full tilt. A volt doesn't sound like much, especially when at work im dealing with 415v on the daily and it ranges from 400 - 420 volts but is acceptable but 1 single volt at huge current levels if you do the math gives you hundreds of more watts and in this case probably 1000 watts and the main benefit is less overheat. I do believe with this technology you don't need to rely on alternators as much. Im in Australia only running a beginner 800w system. Plan is to 1 day run a 3k system, problem is my alternator is difficult 1 to change and its proprietary and the only option I have is to swap from a 70amp to a 110amp. This isnt enough power to push 3k, then the other problem is batteries. Here in Australia we don't have epic products like the US market. But I think my only option would be to get a 'cranking' lithium battery made to start sport cars replacing a lead acid.

Is there something on the bottom of the battery to mount it that way? I'm going to have a similar build. Ordered the battery a month ago from limitless lithium. Still waiting for it to ship. But I'm waiting to build my amp rack with the battery because of the battery mounting

[@NextLevelCarAudio]

So I don’t have anything mounting it down, but because of how I have the wires connected to it, the thing does not budge a millimeter. The sloth of wires in front keep it from moving back and forth and the connections on the side keep it from moving left and right. If you are on the limitless lithium user and dealer page on FB look at my post that was posted on September 24th. Go to the comments and look how it is set up and wired now.

Though you would get simmilar results from both I would get the xp3000..... For one, it was made to be an "auxiliary" or secondary battery. and 2, if you ever get rid of it for whatever reason, it would be easier to sell as the xp3000 is a universal battery while the D3400 is application specific and could limit your buyers.

I have never isolated my setups that run like batteries. ie: AGM with AGM. If you play your music with your car off a lot then it would be beneficial. But if you only play when car is running i would not. as they typically give you a slight voltage drop too.

[@GeneG69]

Why did you have to charge the battery in the beginning? The alternator wouldn’t have done it? Also do you always have to charge it? And where did you get the charger

[@NextLevelCarAudio]

Limitless recommends charging upon first use so that when you connect to car the first time it does not put such a huge load on your alt and potentially burn it up. Plus, it’s good every once in a while to hook up to a charger to top off. Especially on a car like mines that is not a daily driver and sits for long periods of time. I got it on the limitless lithium website. Can also find at D4S.

[@user-jl8rm9kh3i]

So would this work with a 270a alternator??

[@Partyfreaker]

Holy shit! I wonder if i just can use it as a single battery in the front of my car. Can it handle the start engine?

[@NextLevelCarAudio]

For sure! Plenty of people do.

[@josephswift7622]

I just had my 12k pop. Not sure what happened. Had it wired to 2 3.5k skar skv amps to power my zv5s. Wasnt under a load, heard a pop and tons of smoke filled my truck on the freeway, i had to cut the wires from it and chuck it out. Trunk has fluid everywhere, burn mark on the box where it was close too. Havent fully accessed the damage yet. Pretty sad I had to leave it behind

[@NextLevelCarAudio]

😯 holy crap!!! I would definitely let limitless know about that!!!! That’s terrible! Let me know if you find out what happened to it!

[@moneymac5214]

What watts Nd amp you running

[@JevaughnGraham123]

Can you plug in the charger and use it for long periods like playing at an event ?

[@NextLevelCarAudio]

You can but it’s not what it was designed for. It was meant to slow charge over an extended period.

[@passportgang8189]

Can you run these with your normal car battery thats under the hood? Or does all batteries need to be lithium?

[@NextLevelCarAudio]

They should be isolated according to the manufacturer. But some people don’t. I have mines isolated on complete separate electrical systems.

[@subterfuge194]

How would i use an XS power d3400 and a cyber 12K on the same system with a 370 alt? Isolator or no iso? No one gives a definitive answer

[@NextLevelCarAudio]

I don’t like isolators as they tend to fail over time, add another moving part to the setup, and they rob you of voltage. If you daily drive it, you are fine to run them together (though not recommended by manufacturer, more so for liability reasons) but on that note, I would definitely not let them sit together for extended periods. If that’s the case, then better to just install a manual battery cut off for extended store, or remove fuse, etc. to keep them isolated for extended periods. The absolute best way to do it, is to run them on separate electrical systems like in my setup. One alt for under hood AGM, and one alt for car audio lithium. Completely isolated. If that is even an option for you.

[@paulwst6111]

I can use 1 alt 150a to agm and ad DC-DC charger by victron energy (Bluetooth) to charge at 30amp lifepo4 and connect amp?

[@landon0823]

It’s a brand new battery, of course it’s going to do better than them old ones.

Not always the case. If I had this cyber lithium and replaced It with new AGM’s it would not be better

Hey bro I have a question about the charger. I'm about to purchase that exact one from D4sound. How long you say it was before it became fully charged. I appreciate your uploads, very Knowledgeable.

About 3-4 hours I think it took

[@Rumpss]

Hi there love the video.I want to order the 12k Limitless but a bit confused.I am running 2 100amh agms in the trunk and a 60amh in the front.Can i remove the 2 in the rear and keep my front starting battery.Then install the limitless in the trunk.Can i mix them or no.I have a 320 amp ces alternator.Running a crescendo 4k but upgrading to the 6k.My alternator charges at 14.3.Not sure if i can mix the lithium with the agm.Also not sure if 14.4 is enough.Thanks in advance.

[@NextLevelCarAudio]

Your setup is just fine. The manufacturer does recommend running an isolator if you will be mixing their lithium with agm tho

[@Rumpss]

@@NextLevelCarAudio Thanks for the reply. Appreciated

[@NextLevelCarAudio]

You bet. I currently have 2 12k’s for sale. $850 each and that comes with buss bars. Just pay for shipping. Like new condition. Let me know. Later man.

[@Rumpss]

@@NextLevelCarAudio I will think about that thanks.So could I eliminate all my agms and just use the limitless?I mean to start the car and run everything else.Thats the part I'm unsure of.

Of course. That’s how my last setup was. 2 cyber 12k’s and a super cap. That’s it. No starting battery and everything was perfect

what is use alternator?? what Is Amp?? its possible mixed battery? use front AGM battery with ralay/isolator and back lithium secondary battery?

The XS power HF1215 for sure. Made specifically for these batteries and best one for the job for sure. they are $215 new. I am selling one on FB marketplace for $150 slightly used in great condition, original packaging, etc. Since you are a subscriber i'll send it to you anywhere in the USA free shipping w/ tracking. let me know if interested. link to item is below, you can contact me through there if you want it: facebook.com/marketplace/item/655327865172789 Thanks

[@Joe_1776]

Any smart charger with an AGM function will work. (Besides the china knock offs) just make sure to disconnect the battery from your car/system when you charge it and have it at room temp. Not talking down on the charger this man has, it does a great job, but you can get the same charge with a 40 dollar smart charger. But if you have the extra $$ to spend then I'd go for the xs power charger.

i have a dual alternator setup. stock alt charginng underhood AGM battery and running truck electrical. Mechman 370 dedicated to the cyber 12k. i am actually going to upload a video this coming week of my dual alt setup i did just before getting this cyber 12k installed. stay tuned ;)

[@NextLevelCarAudio]

I get it, i have seen lots of people do that.... the reason for me doing it this way is I wanted to keep my stock electrical in tact and also I wanted every amp of my Mechman alternator to go to my stereo and not have to waste any output from it going to power my trucks electrical.
