Are lithium car batteries worth it yet?
Had my first OEM battery last 5 years when i got the car, second one is like 3 years i think or just under which feels shit. Already at 250/550 CCA
These lithiums seems dank, 7KG, 1300CCA and has a reserve button that you press and it can do 300CCA with reserved cells for when it's flat
a 40Ah battery isn't much of a fire hazard
lifepo is not a fire hazard
Aren't they still useless if it is too cold? Having a superlight battery seems nice for a track or weekend toy, but utterly pointless for anything that you want to use regularly if you live anywhere it gets cold
>Aren't they still useless if it is too cold?
>Operating Temperature: -40degC to +75degC
Oh they've improved that? I remember reading a while back about how these things would crystalize and pierce their compartments if ran in very cold conditions.
No, they just heat the batteries when it gets too cold.
Wait for 48volts.
They are coming very soon.
doesn't help in anyway when my car is 12v everything just fires it
I agree cars should be 36-48V so we don't need stupidly large cable
>wires touches your skin
>dies shocked to death
48 volts isn’t high enough to kill you.
It might make you twitch but that’s about it.
Just get a cheap battery charger that does 20+ amps and tbhlfication and your battery will never die
can you imagine having a 60pound lead weight at the front of your car on 1 side affecting your steering lol
Why would it be 60 pounds?
I bought one like this. I’ve been running chink lifepo4 batteries for about 8 years. The a123 cells were great. I had a tiny 4 cell battery about 1/8th the size of an OEM battery that ran my 240sx fine. Later I started using a smaller odyssey size lifepo4 for awhile. It died after 2-3 years and now I’m using one like in your pic. Cost about $300 (costs haven’t changed much). Internal BMC seems better. That’s the only way you really kill these, is with improper charging. Keep it topped up with a trickle charger so you aren’t tempted to use a lead acid charger or something stupid to recharge a dead one. Engine startup is much better than lead acid, weight is much better, but they only make sense if you’re trying to drop weight from the car.
are you competing and need the weight reduction and have already done all the cheap/free weight reduction or are you a larper?
The only application I've seen them be worth triple the cost of an AGM lead acid battery is on motorcycles. Some of the AGM's that I've had, have failed within one year on my bike, even after being hooked to a trickle charger in a heated room during winter.
The current LiPo I have had a 1/2 more cranking amps and you can leave it sitting for months and it'll crank right up.
yeah ignore more cranking amps, lighter, longer life span yep only applies to bikes
AGMs on my cars work perfectly fine for what they're asked of, I don't need to spend 600$ on a battery if its going into a 95 f150 or 04 Mazda 3.
I've only had problems with the tiny AGMs on my bikes so that's the only place I've seen a benefit for litihium instead.
No. For combustion engine cars AGM battery is better choice than lithium.
agm batteries should only be used for start stop cars
I didnt say anything against the regular "maintenance free" lead acid batteries.
And those you don't want to the off gassing of a regular lead acid to destroy.
Lithium is only good for hardcore cranking amps, which is why it's banned on airplanes and catches fire and all that. It's not your main solid and steady battery. Motorcycles you plow snow with maybe, or maybe get it topped up through the winter. But for cars just stick to lead acid. AGM is gay and a profit tool. You're not on a boat or something lol.
Absorbant Glass Mats are Lead acid, and typically the same price as your traditional glass-less Lead Acids. Are you talking about Gel batteries?
Yeah but they suck dick more than your mother. Go ahead an ovepay for them if you really want to shop at the wally world or whatever. Normal lead acids are better at everything. This is beyond dispute and you'll have to start citing datasheets before I shame you with mulitpicity.
>SLA is better
>AGM can do higher amps and is more stable and higher charging currents
yes surely many downsides kek
Which doesn't matter unless you ought a battery made for a trycicle instead of a car. Buy a jump pack like I said if you're way too stupid to manage a fucking dead simple battery. Holy Christ you might qualify for an exhaust shop mig welder at this rat.
lmao you literally said it has no advantages
>doesn't matter!!! wahhhhh
imagine the JIDF sending AMG battery shills to LULZ
imagine hating on a battery lmao
noooo your plates are too strong
Once we all go lifep04 life will be amazing. 25Ah batter doing 650CCA increasing MPG by over 10-15 with weight savings
go to sleep or stop reddit spacing
Dude you have to be 18 here.
oh okay let me know when you come up with an appliicable insult
>Reddit didn't exist til 2005
Those posts are from 04, if you were any age above 18 you'd know that.
reddispacing on 4chon didn't magically become a problem simply because reddit did. What on earth are you even trying to suggest?
That you're an underage moron.
Keep on reddispacing. If you still don't get it you probably never will, newfag.
redditspacing, homosexual retard.
GOT IT RETARD?
I agree. In that case, it's not reddispacing. What's so difficult to understand or an alleged oldfag?
I guess we need more namefaging to retvrn to tradition
I love when stupid people just parrot something they heard then can't actually explain it when asked to. Stay dumb buddy.
American conservatives in a nutshell amirite
I think you have that quite backwards. But then again if your audience is
then I suppose there's no actual discussion of merit to be found from you. Go ahead and blow money on a lithium battery without having any idea at all what the pros and cons might be. I hear they just discovered a big lithium deposit in some new country, so if you invest in military contractors then you maybe you'll have so much money to throw around it won't matter anyway.
>which is why it's banned on airplanes
Same with even SLA batteries >100Wh like lithium. It's because they can't get to the cargo hold and they can puncture
>But for cars just stick to lead acid. AGM is gay and a profit tool. You're not on a boat or something lol.
are you fucking dumb, AGM is a different spacer and packing, it's benefits pass to cars and it's not even remotely specific to boats
None of that is beneficial to a car. You might as well worry agout offgasing and dying like israelites in the holocaust that neve happened. AGM is a profit tool. That's why so many of them are almost free from junk yards because they're not fit for te intended purpose. Why do you think costco sells them so much? Jesus try not to be stupid next time you wake up.
AGM is used exclusively in start stop cars as they need the current draw
>start stop cars
They desere to die. Sell them AGMS while you're at it lol.
So even texas gets a mad cold snap once a decade or few, and what we learn from that is that battery manufacturers sell certain grades of batteries that don't expect to withstand the cold down there (they even have some saying like "winter batteries" or whatever.)
Up north we've never heard of that because the manufactureres sell batteries that don't shit the bed as much in the cold because we get cold on a yearly cycle. So what should you do? Two tips.
1. Don't pay too much for it. Magic batteries are snake oil and AGM for instance is gay and not appropriate.
2. Buy a jump pack and make sure to keep it charged up. That way if you wind up with a gimp battery then you can restart your car and drive it to a place that sells batteries and don't buy that one again. ezpz.
Also, don’t get lipo, they’re a fire hazard and you still get raped. Just get lifepo4 batteries. Downside is 10-15% less capacity vs a LiPo, upside is that they don’t start on fire when damaged. If regulators were worth a shit they’d ban LiPo EVs.
if you buy anything other than the cheapest battery available you are gay
I was thinking about getting one of these small lithium batteries just for the space and weight savings
just get a AGM
one in my merc is 12 years old and still kicking
one in my harley keeps a charge all winter and fires right up the spring
>one in my merc is 12 years old and still kicking
lol bull fucking shit. AGM is still a sealed lead acid battery no way it lasts that long
>I can only wonder why isn't this standard equipment already.
my bad, its 10 1/2 years old. Still goes weeks without starting no prob
There is no way a w220 can sit for over 1 week and still start
They're absolutely unnecessary on a daily driver, AGM is a huge improvement if you're looking to upgrade.
Lithium batteries are useful on vehicles that are rarely driven, where you can't use battery tenders, and/or high cranking amps are needed.
I'm looking at getting one for my motorcycle for those reasons, and because the starter and spark system don't like cold starting on the carb without starter fluid.
I'm running a chink lifepo4 battery in my 02 A8 (D2). Being in yurop, it's naturally a diesel (3.3 BiTDI). Previously it ate batteries every 2 years, because diesels need lolhuge cca to start, even though it doesn't get worse here than -20C (don't know what is that in freedom/eagles or whatever). When I first installed it, I thought it would ruin the starter, it started like it was jumped. Now as it discharged to a normal level, it's just starting quickly in any conditions from freezing to scorching, even if I had the engine off heater or the engine off fan on while I run surveillance with the dashcam.
Especially with modern shit like start stop I can only wonder why isn't this standard equipment already.
>the AGM industry has paid shills posting on LULZ
I only buy aussie made batteries, best in the world
I've got that same one in my daily, pic related. It was worth it for me because I use the car for camping and run a camping fridge directly from the cranking battery since I don't have any room to put a dual battery system. It's especially useful to me because of the inbuilt reserve/backup option, if the fridge ever drains it completely.
I got the 40ah ( plus 10ah reserve) version and so far the longest I ran my fridge off it between engine starts was 2 and a bit days. Car still started no problem. Have been driving the car with it for nearly 2 years, never had a problem. Charging directly from a regular dumb alternator. To get this much capacity in lead or AGM would be close over 20kgs and wouldn't fit in the place I have it, this one weighs like...5kg maybe? Easily pick it up with one hand.
The way I see it, literally the only downside when choosing lifepo4 over lead for a car battery is the initial outlay. That's it. Even the long term cost is cheaper since you *should* replace a lead battery every so many years. Cheapest lead based battery where I am is between $100 and $200.
Usable capacity, depth of discharge, weight, CCA, voltage drop, operating voltage...lifepo4 kicks leads ass in every conceivable way.
I built my own from LTO cells.
10/10 would do again.
Mirin digits. Those look like they would kill you if you short them...
How to deal with lithium being much more dangerous than lead-acid?
LTO is not dangerous at all. You can do anything to those cells, nothing much will happen.
>i believe this chinese video
>chinese made amazing battery for their electric busses that no one else uses weird!
>can't scale the tech down though!
How does one manage to be wrong at so many levels at the same time? Does Google not work in your shitty country?
>Yang, Xiao-Guang; Zhang, Guangsheng; Ge, Shanhai; Wang, Chao-Yang
Very impressive, sir. Good job.
god i can't wait for car batteries to go the way of the dinosaur
give me a super cap anyday
Then buy one. Lead-acid is well suited for a variety of common applications, typical cars and similar machinery included. Let us know how much it costs and how well it works.
Unless these have some circuitry to protect the cells in these, it's a fire waiting to happen. Lead acid is very happy to sit up to 14V while lithium batteries are not quite so flexible.
Just put a new AGM battery in my mothers truck today, weird timing for a thread about batteries.
>Lead acid is very happy to sit up to 14V while lithium batteries are not quite so flexible.
bro you literally charge lithium at 14.6V and the float is 13.6 usually. Car batteries dont usually sit at even 13V. Cranking batteries aren't deep discharge batteries
They must have the circuitry built in now. Worked at a battery shop when these first started coming out and you had to use an adapter that would limit the charge voltage so it wouldn't fry the lithium. Nobody cared though since they were mostly used on motorcycles and other small shit that changing all that out wasn't an issue.
they have always had a BMS to handle charging individual cells and to protect them
I've got the one in OPs photo, been driving it 2 years connected to a regular alternator, it has charging circuitry built in plus under/over voltage cut off and short circuit protection. The only thing it does do which is less than ideal is if I've run the battery down a bit with the fridge, upon engine startup the battery will pull max current from the alternator even at idle which leads to belt squeal sometimes. My alternator vee belt doesn't live for very long, either.
If that's a common thing, it might put your alternator to an early death. You could wire a power resistor (which could take the form of something as inexpensive as a light bulb or just a long run of jumper cable stitched together until it acts as a sufficient current limiter) between the alternator and the battery.
The problem comes in if you really need max amps out of your alternator continuous rather than being able to use the battery as a buffer, so unless you want to do something clever with a dual battery setup, or a relay or even just a cool big switch or underhood plug to bypass the current limit, you'd have to make some decisions. But probably not decisions you need to make until and unless you discover that it does in fact put belts and alternators to an early grave.
Might be cool for the weight savings.
yep every GR86 owner should have one if they actually believe the dribble they spout about their car
I actually need the heavy battery though, because my car is front-heavy as fuck and the battery is in the rear. Kek
I buy agms because they're only a couple bucks more than the standard battery at the parts store and have a longer warranty, and I just go and run it down and take it in for exchange claiming it failed just before the warranty is up anyway. that one $200 battery has "lasted" nearly a decade now lmao.
liar. batteries are all on pro-rated warranties.
I run a lithium G30 batt in my race car.
Crazy powerful for a tiny 6lb battery.
Can be 100F or 30F and that battery doesn't seem to care at all.
The manufacturer said it will easily last 10 years or more
But I don't think I'd bother spending $700 for a battery for my daily.
I can get a DEKA lead acid battery to last 5 years for around $200.
Maybe I'd you had a nice sports car or better
Tell you what I picked up a $40 lithium jump pack from the wallyworld the other year (cheapest such thing available witihin reasonable carless travel distance) and I've been rather impressed both with its programming to deal with adjusting to and reporting different kinds of faults as well as how hard it kicks in and cranks as needed for someting like the size of two decent hamburgers.
It claims only 3 cranks per recharge unless it's an emergency, which is probably about right for something of its size in order to avoid an even shorter battery life than it might really have. But that's pretty handy for the cost. I wouldn't run lithium in anything short of a special project, either. That thing and a fancy motorcycle battery is weight savings enough in the 90s/00s sense of it.
not worth it in a car. worth it in a motorcycle.
