Headway cell help please! Need HUGE bank!


Recommended Posts

I didn’t post the body of text correctly apparently….I’ll try again! I’ve been doing the Audio thing since I had the XXX 18” in the downfire in the SRT….Quite a few builds since then….my current build….I’m struggling with this headway cell thing! Pushing 3 custom 12”s  4” dual 1ohm. Wanting to run the Taramps MD12000.1 @.5… For the doors I’m running a 3 Hifonics Gemini Elite 1400.4s…..I’ve got a good amount of amperage draw going on. The MD takes 1200 amps and my other amps are under 300 total. Quite the draw for an Infiniti Sedan. For juice there’s a 350 amp alt on there…..under the hood there is an XS D3400. 
I was running 6 D3400s but it was waaaaaay to heavy causing the need of coil overs and some toner stuff, so delete. Now I was onto the Cyber 12k….but am also aware of people building their own banks. One Cyber 12k wouldnt give me enough power for my set up….not to mention I rather have some good reserve on deck….So that leads to 2 12k batteries…..kinda spendy!!!! We gotta pay to play I guess but I’ve already got 10 gallons of resin into the box! Cut me a break!  Headway cells are now around 5$ each!!!! Wow! So, there’s the answer right there, for me anyways! I need some help though. I’m far from pro so I was hoping you guys could help me to build a big bank. With there being a 1200 amp draw from the one amp, how do you manage that? Is that in the bud bars ability or the terminal? Also to what is it, BMS….battery management systems???? Is that what that is? What are they used for? To balance the cells and help ensure charging and drawing is balanced? I don’t know why the importance of balance either……I’m kinda wet behind the ears with all this power stuff…..so I have a lot of questions. Temp sensors, are they an option? Monitoring individual banks, is that an option,voltage wise……fans, needed or not? I’m intending on buying the Headway monster battery packs that come with 48 cells running at 24v. I can break that down and turn it into 12v correct?…..I intend on purchasing 2-3 of the monster packs depending on how many cells is advised I use. As soon as I can get some feedback the sooner I can start this with more confidence. With the draw in my system built the way it is, would it be better to have separate banks? One for the bass and one for the other amps?  I’m ran Kolossus Flex 4/0 for pos and neg from front to rear says it does 600 amps. Little overkill there, I’m just trying to help with the drops. Notes about build for those interested, removed the back seat metal from my Infiniti G sedan. Triple Baltic baffle front facing sealed in the trunk with double layer birch and boat fiberglass. Box measures 10 cubic feet. Ported, interchangeable ports thru the top parcel shelf. Yeahhhhh, bassheads wet dream. Custom carbon fiber XXX subs doin’ 4500 each by Mr.MusicMan. Doors housing 14 6.5” dc audio pro mids & 8 skar audio 300 watt bullet teeets. Kenwood DDX runs to SSL 3 way cross to the amps. Using all SHCA connections and shrink wrap. Ferrules not lug style. Cleeeeean! I can’t wait to get it into some lanes. I just need some seasoned help! How do I build an atomic bank of headway cells!!!????  Thanks everyone. Thanks too to Steve Meade for creating a place for us to get it off our chest! I need help! MaydayMayday!  Another note, Headways are the choice when you don’t want to or can’t raise your vehicles voltage? I have to run at 14.4. Anything over 15v and I can fry some of the wiring ….closer to 15.5 or something but I don’t get much before I fry boards……with all the power upgrades I run at 14.4 always, unless there’s a lead on the ac then I run at 14.2. Thanks again!

Got some questions mate. 

 

 

"Pushing 3 custom 12”s  4” dual 1ohm. Wanting to run the Taramps MD12000.1 @.5"  - Wut? Youll be closer to .7, more most likely.

"The MD takes 1200 amps" - Are you burping ONLY? Then, no, it doesnt, you should know, if your running one. Music, even heavy demos, usually pull around half of MAX draw/capable.  

" For juice there’s a 350 amp alt on there" - I got to know, who makes a 350amp alt, for a nissan/infinity. 

"already got 10 gallons of resin into the box" - Bummer,.. that was a waste. 

"Kolossus Flex 4/0 for pos and neg from front to rear says it does 600 amps. Little overkill there" - I thought one of your amps pulls 1200?

"Ported, interchangeable ports thru the top parcel shelf. " - Can i see that? Id think to be able to swap, they would all be hella short, to even get by the rear window, and in the enclosure. So are you tuned to 8hz or something? Serious question. 

"Using all SHCA connections and shrink wrap" -I only see 3 SHCA shrink wrap, zero of Jon's connections, and i thought it was Kolossus 4/0 ?

"Doors housing 14 6.5” dc audio pro mids & 8 skar audio 300 watt bullet teeets." - Please post a picture of this, i have GOT to see this. Awesome. 

" Box measures 10 cubic feet"  Biggest trunk for a Nissan/infinity is around 12, for the sedan, and about half that for the coupe. But ive only worked on a couple Nissans.

 

This is a bit over 6 cubes (with vent) in a trunk with 14cf. (2 12's, ampere audio 9k tfe)

3 D7500s, 1 D3100, singer 240 hairpin alt, just fyi

 

 

 

Also, when using a fuse block, the one,...please use BOTH ends of the block please, hell, a fuse even.

Would you like to try again, with actually what the hell you got going on, right now, and not a pipe dream, skip the bullshit, and ask questions that are in fact in your wheel house? We would love to help. And can. You (even in dream land) are NO where CLOSE to needing your 1500 amp (the 1200, and 300 you mentioned, even though those gemini's say 60 amps total for for 1400 watts, which is,..... silly). Wanna try again? 

 

Cheers.

Thanks anyway for all of that. I wasn’t able to find anything useful in any of that. My radar was pickin up all types of h8h8h8.  Maybe it was that they’re dual 1 ohm subs with 4” vc or maybe it was the money I put into resin, some can’t afford it…..maybe it was the research involved with finding a 350 amp alt…..maybe it was the 20$ a foot wire to help prevent any unibody glued together spot welded like crap drops…..I don’t know…..really I think it must be getting rid of the 6 d3400 XS and building a bank……I think most of all though it had to have been you h8n because the best you

could come up with was a Buncha Rawrawraw and a unimaginative build. I bet you would love to see how I accomplished it.   
Thanks to the guy above for the advice. I don’t know anything about power really……the electrical

side of a bank build….so, any help is great.

I picked up a couple superbeast headway banks to break down and mount to some bars. I do need sensors and BMS though. I’m still

figuring it out. 
and that other guy again, you really didn’t say anything. You just attacked me like a cheeseball, without any substance behind what you’re sayin’. Not to mention, you’re garbage was full grammatical errors. Where they do that at?
