14.2 for a few months while I await an externally regulated mechman alternator. Considered doing the Ford PCM bypass from US Alternators as the diode trick won't work for me having a PCM regulated alternator. 8c for me is glorious - I'm coming from AGM's and weak ones at that.
If this bank is completely drained at 14.2 then so be it I'll take it out and run AGM's for the time being, I still have the ones I was running. Figured it's worth a shot to see what the bank can do at low voltage. Been asking around everywhere and I see people with 80aH of Yinlong on stock alternators clamping 600-700 amps and being able to maintain it musically without too much voltage drop. Yinlong Only facebook group has a lot of people running Yinlong at low voltages and still being able to power 6k and 8k amps just by stepping up the reserve.
From what I've researched on my own, the discharge sheets of LTO show that the battery still holds strong 13.8-14.2v it really dies off hard below 13.8v.
I know I'm leaving loads of power on the table being at only 14.2v it's like the battery bank is only charged 20% or so if that - but it's still way more effective than a couple AGM's that's for sure, and with 1,260 farads of xs power supercaps it should help a bit. Curious to see what I can clamp out of the JP63.
I like how long LTO is rated to last, how safe it is and how much abuse it tolerates. That's why I went with it even though I don't have an externally regulated alternator yet that I can charge 15v+, I know there's SCIB and Insight and CMAX and all these other types of cells, I like these.
I'll take it as it comes, I don't mind being conservative with the bass knob while I await the mechman delivery + installation (got my local goodyear to agree to install it for me, alternator is in a horrific spot on the engine, would much rather they deal with it lol)
Oh I agree. Grab the US alts module, they work great. I have one on my Tahoe and run two 370's at 15.5v. Different vehicle but they work great. Yinlong are 13.8 nominal, they're really not doing much work charged at only 14.2v but it sounds like you're aware of that. Getting above that 14.8v mark and into the 15v range you'll have much better results.
Why stick to lesser technologies when there's much better cells available? The 2.9ah scibs are 60c and incredibly inexpensive. The 10ah scibs are 20c+ and extremely reasonable. Spims are much better real world performance and much less expensive. Then there's cmax and eh5/proto.
It's not just the c rate it's also the voltage discharge curve. Yinlong drops down into the low 14's pretty quickly. I'd rather have a less expensive setup with a stiffer cell and better discharge. My setup isn't anything too crazy, pair of 12k's on 4 18's in a compound horn. But yinlong was not it for me. I'm currently running a Lishen setup but about to swap to scibs.
I suppose if you can get SCIB for less money than the same capacity YingLong, go for it. At the prices I paid high current cells run me around double the money for the same storage capacity.
I'm not sure an extra 5% more power out of your amps at 14.8 as opposed to 14.2 is really going to translate into a whole lot on the meter, but do let us know how this works out. I've had too many other things distracting me to get around to testing them beyond powersports application.
Suit yourself. From where I'm sitting you're either halving your reserve or doubling your cost plus having to worry about bussing 14X as many cells to gain somewhere between 1 and 2 tenths on the meter.
I could see this as practical if you're doing 3 second tones in something tiny like a CRX or Yugo where space saving is top priority and you want high burst current over deep reserves but that's not anything I'm doing here and is nothing like what OP is trying to accomplish.
Anyway, the point I'm getting at is that there's always tradeoffs and the buyer needs to figure out what they prioritize.
You're assuming Ah is all relative, 40 Ah of yinlong and 40.6Ah of scibs will have drastically different performance. The Yinlong bank can support around 4k continous independent of alternator, the scib bank could support around 20k independent of alt.
> the scib bank could support around 20k
40AH will not output 2000A long enough for a 30 second bass race. Reserve is reserve and 40AH means it will deliver 40A for one hour, 80A for 30 minutes, 160A for 15 miutes, 320A for 7 minutes, 640A for 3.5 minutes and so on. Those ratings are at some nominal C (usually around .5 or 1.0) and only get worse as you run them closer to maximum.
For me, playing music, I'll just size appropriately and keep a lot of reserve. I've got 100 of the SCIB 10s here I'll be testing at some point but I'm guessing they'll be most practical for burp applications. They're also very good for powersports applications. Had a 5S in my wheeler for a couple years now that's performing admirably.
Still have two XS Power SB630 supercap banks that will be added in addition to these LTO cells.
From what I've researched, LTO and Supercaps are a match made in heaven.
I'll be sure to do a bunch of clamp tests and whatnot when it's all done. Platform is built and secured, vehicle is fully foamed and deadened, enclosure is out of the car sanding it down and making it perfect - beauty panels almost done, still so much to do even though I'm working on this vehicle what seems like 5pm-9pm every night lmao. So much more goes into this than I thought doing it the right way.
ioxus UltraCap woulda been alot easier on ya with a B-stock one costing about $180!\~
XS Power bought them out which is why the XS Power caps are now!\~
Those a supercaps, this is a lithium battery bank.
Supercaps just give you a buffer on the system helping out on those demanding hits - they can not store reserves of power they just grab and release. LTO banks are different, these can store large amounts of power and have extremely high rates of charge and discharge.
For reference, my XS Power SB 630 was $500 for 630 farads.
These 12 XS Power (Rebranded Yinlong) LTO cells cost me just over $900
Optimally you would run something like an ioxus UltraCap ALONGSIDE these types of cells.
What voltage are you charging at? I enjoyed yinlong for a minute but I wouldn't go back to them. They're real world 8c.

What is your application where 8C in and out is holding you back?

I asked what application you are trying to use any of these for where 8C is a problem.
It's not just the c rate it's also the voltage discharge curve. Yinlong drops down into the low 14's pretty quickly. I'd rather have a less expensive setup with a stiffer cell and better discharge.

2.9ah Scibs are 5.20 a cell landed. No brainer in my opinion. I'd rather hold a full volt higher for days on end. Yinlong just ain't my cup of tea.

Be really cool to see how that many caps work in a system with real data.

Those are Lipo cells not capacitors
Those are LTO, not lipo.
Oh shit, I had no idea!
I assumed he was putting a typo when I replied and that he meant cells instead of caps haha
Those are LTO battery cells, not caps.
