You can build this bank with the xs power 45 which is rebranded yinlong but a 6 bank series is 45ah not 40h same shit Big D has here just 45. Anyways you can get a 12 cell bank of either the 40ah for 900 but the 45ah is 100$ more it's a lil over 1,000$ but that's 12 cell bank 90ah all the bus bars, bolts and balancer from Big Jeff he has both even the 35ah for a lil cheaper.

Just did 3 of these. 240ah. Replaced all my 7 titan 8 12volt. What a difference. Single 400 amp mechman alt. Ext regulator. Charge at 15.8-15.9. They will hold 15.1-15.3 for a minute with about a 1500amp current draw. So 500amp per bank. After about a minute it starts slowly dropping, but it’s rarely playing for more than 10-20 seconds at that volume. They also recharge fast. Back off the volume they are back at 15.8 very quickly. I could not more highly recommend these. I did 240ah with very nice bars. Each end accepts 10 sky high oversized 2/0. Total cost $3225. $1075 per bank. Great video big D.

@@GTILOUD I bought them in premade 80ah banks from CES. Much easier. Looks a lot nicer. Balanced and ready to go when you receive it. On any search engine type in ces 80ah. First thing that pops up.

[@evilinside5984]

@DrMichaelPetty- Im not doubting your experience with the Titan 8, but were they the PWR= power, or RSV= reserve? Also maybe something was not right in your setup, or the New Titan 8 PWR batteries are much better now? Because i just recently seen a test, where only 1- Titan 8 S6 PWR (10Ah @ 75c!) battery was used (only had a 6amp charger hooked up for the test), and it only dropped 1.8volts (16.0v to 14.2v) and powered an amp to 11,400 watts R.M.S. On the Smd amp dyno, with a 1,000 amp draw! The test bigdwiz ran in this video above, with the 2 banks of 40Ah YinLong Lto, (so 80Ah total), dropped from 15.0v to 11.0v with a 500Amp draw= 1/2 the amperage draw, and more than twice the voltage drop! And only made 5800 watts on the dyno.

[@evilinside5984]

@DrMichaelPetty- That 400 amp alt. charging @ 15.8v supplys 6,300 watts all by it self, then each bank of 80ah yinlongs support 6k, so x3 or 240ah= 18k of battery power, and 6,300 from alt. Power, for a total electrical power output, that would support 24k. The Xs power 6S Titan 8 PWR, charging @ 16.6v with a 400 amp alt., would only Require 3 of these tiny batteries ($799 x3= $2,397) to maintain 16v, with a 1500 amp draw.

[@recon440]

Also, I would like to add that for car audio applications there are effecively no BMS modules that can efficiently sustain the current draws we may see (400A+). As such, nobody really runs the BMS in the car audio world. I would like to see a retest of this battery bank without the BMS.

[@timhoover1416]

I guess as a person who does not know much about batteries, you did not see the gigantic bus bars that you connect to the amp. The BMS he was using did not control the flow of current from the battery, it only maintains the balance of the cells to each other. I work for the sister company to Yinlong that actually licenses them the LTO to make these cells. I'm an engineer, so I know what I'm talking about. There are BMS modules that will run the power through the BMS, don't buy one of those for high power applications like car audio.

[@KuntalGhosh]

No need for bms. Just use a cell balancer.

[@catch22frubert]

@@timhoover1416 There are definitely stand alone BMS units that can handle 500 amps continuous. Daly makes a 500 amp smart BMS that can do 500 amps continuous and I believe well over 1000 amps burst, and the BMS settings are accessible and adjustable. I've seen them for Lifepo4 batteries, but I haven't looked for an LTO BMS yet, but I'm sure they are out there. You are right though, the BMS would be a constant parasitic drain on the cells, and not desirable, even with the extra safety it provides. LTO Cells are already really safe and can take much higher Voltage than most car alternators provide, so I can understand why most people only run an active balancer with a 6s setup of LTO. Battery hookup has a nice little setup of LTO Cells for $200 that would be perfect for automotive duty, but I think I would probably want a 2p6s version of this setup, so at $400 plus balance board and some kind of Case, it's not so cheap anymore. It's probably still worth it though, just because they will outlast the car you put them in, but that's an argument you couldn't win with some people with a different viewpoint.

[@neildeatherage2269]

@@201231 I recently purchased that Ioxus cap opting for B-stock for 200 vs 400 (a couple days just about every vendor reduced regular price of 400 to 300) which only had some scratches and a little chip on the plastic seem. Purely cosmetic and honestly can't believe that cut the price in half. At any rate I am literally obsessed the cap it is unreal. I can't believe they don't seem to be gaining the traction they deserve. Running 2, 1k monoblock amps with factory premium amp (650ish watts) while charging my phone on a AC/DC converter with Heater/AC full tilt, windshield wipers on, and no perceivable voltage drops, lights dimming, and subs hitting so much harder maintaining consistent power with hungry continues trap bass lines. I literally almost want to purchase another one just in case mine gets stolen or breaks for some reason and they sell out (noticed some websites B-stock is getting low). But I figure with a 10 year or whatever it is warranty by the time the thing goes out whatever is available will be better or perhaps smaller which would be welcome. I still might buy another one while I can get one for 200 bucks for a christmas present or something. Father has a diesel truck that needs 2 batteries and a ton of juice to start so while not a basshead like me could use one of these and only 1 battery and not get stuck somewhere like we did the other day. Have a 5k amp on the way thats happy at mid 12 volts (sure you can guess which one that is) and just going to use my current 120 amp alternator (big 4 of course) and one XS AGM battery sitting next to the cap (have new LA battery under the hood, no isolator no issues) with 100% confidence. Just get one but please leave one B-stock left me me haha

If they don’t want to be paired with agm batteries is that for an extra battery or for the main battery too?

Main battery but not under the hood you would do a battery delete and place the yinlong away from heat

[@phillipbainbridge9107]

Discharge and recharge the bank a couple times. It will improve.

[@lorcro2000]

LTO batteries don't have very good discharge efficiency so the capacity isn't quite going to match 40 Ah. They do have some other benefits, though, but LiFePo4 is probably still the best way to go.

[@iamjackalope]

This battery pack needs a bank of super caps to allow it to charge and discharge with out over heating. Draining those batteries like that dyno run did they won't last very long.

[@lorcro2000]

@@iamjackalope LTO cells are fine with being charged and discarged at 10C. That translates to 400 amps of current going in and out of them - per cell. Once you add six of these cells in series, you're looking at a battery pack that you can push 2400 amperes into/out of. Not that that is possible, there are too many other limiting factors, like the fact that 2400 amps at 12 volts would melt cables.

[@lorcro2000]

@Dave Micolichek Huh, yeah, you're right, I wasn't thinking that through. But still, you'd need one hell of a system to draw more than 400 amperes (and at 10C they can deliver that).

[@samohraje2433]

LTO batteries are quite odd for music aplications.. they can be used as a off grid solar system battery pack due to the cycle ratings ( Propperly charged and not full discharged etc. up to 25 000 maybe even more ) so they are worth it against Lead Acid but they are much mooooore expensive and BMS board is expensive too aspecially the more than 6S BMS for some type of aplications like power inverters from 24 to 230 Or 110 50/60Hz with huge ammount of power. And yes they are quite a bit expensive than LiFePO4 batteries but they have a highest longevity from all batteries. And also they could have 100Ah per one cell and they are i think 3.2V maybe idk 🤷‍♂️

[@mitchellroberts7954]

With 6 cells pulling 250a per bank at 40ah, you're putting a ~6c load on the cells and getting about .67vDC of drop per cell. Not surprised at all you dropped to 11vDC. Lithiums are great but they aren't magic. I've been asking for months for someone to get C rating charts for the cells because that's what's going to actually tell you how these cells handle load. The sweet spot is generally between 2-4C (80-160a per 40ah bank), so in a vehicle with an alternator you can expect significantly less voltage drop, about an entire volt or two less, but you really do need a decent sized bank and alternator to back it up (or time to recharge). 250a per bank is a lot.

[@mitchellroberts7954]

Keep in mind that this is still far superior to lead acid or even AGM. You see people with hundreds of AH of batteries not 80ah. 400ah of batteries with a 500a load is what, 1.25c vs this bank at 6c?

I've been run an 80ah bank of lto with two 400amp mechman alts (15.5-15.8) clamping 11k-12k of amplifier and the bank has been loving it.

Power wire basically 1/0 from the lithium + all the way to the battery isolator + into the front of a battery front main battery + So once we cranked the vehicle over (depending on what you're charging voltage is) Will it put for example 14.8v to both battery and lithium cells.

Damn. Lithium is Starting to get a little cheaper. My 2 50AH Lithium Batteries Were 740 Each. And They Can Only Dump Maybe 600Amps Total (Limited By battery Protection Built In) I got them for Capacity. My 8 Banks Of 6 Ultra Caps Do The Heavy Lifting As Well As My 2 320 Amp Mechman Alternators.

Really clean setup but seems like a huge investment and allot of custom fabrication gotta order this gotta get these made even order hard to find nuts For the average guy jus stick with a AGM or any of the other quality car audio batteries unless you've got money to burn Just doesn't seem to make sense for the everyday average guy or stereo Still good info love your channel

[@mitchellroberts7954]

80ah of raw cells is only about ~300. Big mark up when you add custom bussing, casing, and balancing boards.

[@wal]

It is a big investment and a lot of SPL guys are using these. The Headway LiFePO4 cells are better for the average car audio DIY guy

I believe up to -20c.

[@Mr2SMOOTH24]

@@TechieTard thanks bruh

[@recon440]

In regards to the poor performance on the amp dyno, the reason is due to the BMS which limits discharge/charge current. You can effectively think of the BMS as the gatekeeper for any current flow. As such, you will see drastic losses in comparison the when it is not used.

[@IGMWN]

I know this is an old comment, but no. In this case, this BMS, is only used to discharge cells that are higher than the lowest voltage of any other cell in the bank. For a BMS to work the way you are describing, it would have to have the main power of the entire bank routed through it, which his BMS does not.

[@murder5000]

Great video. This helped me alot.

[@wal]

😬👍

[@303nitzubishi4]

So if they rest above 14 volts then I'm guessing you will need a standalone 16 volt alternator to charge them in an automotive application? The oem 14.4-15v isn't going to be high enough potential to push current into these once they are near full charge

[@darrellw22]

Great video great info.. im thinking about getting some Yinlong lithium but i keep hearing if u drain lithium off all the power they are trash after that and they can't be recharged after all the power has been drained. Dont know how tru that is? 🤷‍♂️ i appreciate u Old school keep them car audio test coming in .👍🏾 oh and can u pls see if u can do a test on the new Taramps MD 12k .5 ohm version thanks.

do you use stainless nuts? I think it's important. magnetic metal also on the battery. Do you not reduce capacity when you series connect?

[@willieurus]

I’m confused what is this for Is this replacing car battery for car stereo or is this for home use

[@cfmechanic]

I hear the noise sounds like alternator noise. Were u saying with a bank of these that I can delete my factory battery. Right now I use agm under hood and optima bluetop in the trunk. I would be looking to build a bank a bit bigger than yours. Maybe 6 more cells

[@jamest.5001]

I have been thinking about getting a few of these to power my home, since they have basically have the life span of a capacitor, I wouldn't need to buy batteries for 20+ years, I need 2k ah, at 24v!

[@wal]

LiFePO4 is closer to 12V (per bank) and those may work better for home solar system (in series for 24-26 volts)

[@image91]

Hm. Looking at switching over to these but so far all the claims of 5000w & 4000w per 40ah bank seem to be false. Also seeing that you mention that they are optimal when charged to around 15.6v. Considering I charge at 14.2v , would you recommend these? Looking to run around 10,000w on bass & 5,000w on mids/highs with a 250A alt. Will either be running 120ah lto & a 1260f super cap bank or 160ah lto. Not sure which is better. From your experience, any advice? Thanks & keep up the great work bro.

psychiatric treatment?

[@Swenser]

Are these cells really explosionless/fireless? Please test and short one out for us.

[@DaaaveO1971]

That's a scary amount of lithium cell power there. They usually behave and don't burst into flames...so that's good, but can they stand up to the thermal extremes, vibrations, dirt, water and grime that a normal lead acid battery can under the hood of a vehicle? Unlike these, you can leave AGM batteries to charge unattended. If you get in an accident, do you need to tell first responders (especially firefighters) that you have these in your vehicle? Will you car insurance cover you if you drive around with these?

[@wal]

I can’t answer the insurance question, sorry. Good points and I’ll make sure I mention these in future lithium vids

[@311kam]

You don't want to put lithium under the hood, no.

[@DanBowkley]

7n-m works out to just about 62 in-lbs, for those of us using imperial measurements. I'm pretty sure Harbor Freight has a 1/4" drive clicky torque wrench that'll take care of that for maybe $30.

[@Jpilgrim30]

You can find 12mm x 1.75 nuts at the auto parts store. A lot of ford trucks and SUVs used open face nuts that size for lug nuts. They even have serrated washers built on to them as well.

[@wal]

They were MUCH cheaper at BoltDepot, even after shipping

Let’s go off grid with this , get the 1200 a2 and run a blender at 60hz with your cap system charged by the sun. 😂

[@SlamryCamry19]

Hey can you please tell me if there's a way to use just this in your car as your power supply/ starter battery I'm trying to get rid of the lead/acid battery and go straight LTO for the best possible performance from the front of the car to the back I'm limited to the stock alternator because of my car 2019 Toyota Camry ( ONBUS LINBUS electronics build) but every dealer I talk to about these or the xs power cells all want to upsale me to 2-4 titan 8's that's 1500$-3000$ a lot more money than I have to spend and I'll only get the same 30-40 AH of LTO that a cell bank like this has for half the price

[@TheTimshady337]

Nice setup. I have some prismatic LTO's 20ah though

[@rourkebuys1791]

Big d wiz nice. Only q is .is that aluminium links isolated between the 2 banks? Or is each bank in series? And the links connect the 2 banks in parallel?

[@magicmikebangin15s64]

Basically series Parallel Series as in to get 13.8 v final Parallel as in , in series side by side parallel. If that makes sense or I may not be explaining it correctly. As you see 1 side of the bank the other side is exactly the same way. Pos-neg-pos-neg ect...

Hey Derrick do you dalethe LTO 660 batteries

[@neptunevibe]

Big D you should pay attention with that charging protection. I don't think is working anymore in this setup. To charge all the same you need to connect each element to the + of it. You made pairs but not necessary they have the same voltage in them. Is like putting all in parallel with no protection and charge them directly on the network and thinking: "man they must be the same cuz I charge them all at once". I don't think this works on elements as you did. Don't know. Worth investigating with a multimeter.

[@blackflworer]

Im new with the lto, so i got my self 45ah yinlong bank. Is it safe to use it with stock 90a alternator ? I manage to charge it up to 14.6. I use 5k amp on it and i never drop under 13.7...13.8. Is it safe for the alternator to charge the bank and not overheat or burn since i heart lithium haves lower resistance ? I use only balancer for the bank, my car is old and haves no bms i think.

[@theodoresignal]

The 6s charger has been sold out for a while. Any other options

[@jamest.5001]

I'd still run a capacitor! They give up the current soo fast, a small bank of super caps, maybe 6 600f caps, that would be 100 farad, along with the lto, charge to 15v should do great, and possibly not drop a volt on music, great video!!!

James, I really feel that it's a misconception. I've done testing myself and input voltage didn't matter like that. I have asked multiple people to provide video proof that lower input voltage magically makes them more efficient but I have yet to see it.
