Voltax are getting a pretty good name out there and in my opinion $520 for a 135ah lithium is getting very close to a quality lead acid. I bought two of these on the 8th and they arrived in country NSW yesterday on the 11th.
Edit: Cheaper here @ $498.88 https://www.ebay.com.au/itm/12V-135Ah-Lithium-Ion-Li-ion-Bat…
Are we talking about using these too replace our car battery? If so what advantage using a Lithium based battery over lead acid battery
I wonder what other uses one could use with this Lithium battery sorry like sounding like a noob 😂
edit: so this battery is equivalent too 135,000 mAh battery?
Most likely for camping, boats etc
Not for car batteries mate.
Solar systems, telecommunications, power tools, camping etc etc.
These are no cranking batteries so no.
It is for auxillary power. Fridges, air compressor, water pump, lights.
Ok cool so second battery in a car/vehicle for example too run devices when the main vehicle battery isn't being charged (i.e. vehicle motor on recharging)
these one can have multiple charge cycle, weight much less and last longer, unlike acid battery which only have about 200 charge cycle and go dead easily if you let it go down below 50% capacity
it weighs less than my 100ah Enerdrive,according to the description,135ah Voltax weighs 12.5kg,100ah Voltax weighs 9.5kg
my Enerdrive 100ah B-tec weighs 12.6kg.
A WA co. makes a 100 AH battery (large, but lighter?)
B4 I'd pay ~$500 for a battery, I'd want to see a longer-Life Warranty, than our generic 12-month ones (min., by Law). I doubt eBay vendors offer Longer Warranties.
Look round on YouTube for HowTo's that feature OR compare this type (Not brand) of battery to 2 or 3 other types, that list various applications, from storing your Solar or Wind energy, to replacing a vehicle battery.
(One, in particular, has an older chap at a repair show, with his RV, talking-up the WA-made battery, -vs- an import… He's half-interviewing a German repairer or auto-elec'n on the differences between the 2 battery technologies, etc.
These guys talk down imports fr China, saying they are very cheaply made inside, won't last if you try to draw "too much" current. See that video OR similar for details…
But… buyer beware… Thinner layers of some material inside can mean shorter life-expectancy, etc. The one's from WA are ~Twice the cost, so dig deeper B4 you choose, in case you get better battery-Life from one over the other(s).
The video should be easy to identify, as the older guy may be well-known as a TV RV-traveller in Outback AU. Don't recall if the above-cited video is one in his series, or not.)
Be careful to check, that you're using the right Charger…)
Lead Acid: Should really stay above 50% full level
Li-Ion(?): Not quite as robust as LifePO4's, but you
may be able to use more than ~half of its energy w/o killing it.
There's a web site: ~Battery Univ'y (from memory, so don't trust it… ;~) with lotsa info sheets, etc. on all this:
(IF you get the choice, choose Boston Universary, instead, if only for the Culture of Boston, during your free moments… Much more Fun! ;~)
Dunno if there are any better sites…?
(Brain-Trust, chime in, ~now)
FWIW, Amazon..AU has:
"Mustwell 1PCS 12V 100A 4S BMS Li-ion LiFePO4 Life LMO Lithium Battery 18650 Charger Battery Protection Circuit Board 14.4V 14.8V 16.8V 4S"
$14.00
There's also a YT vid out there on assembling your own LiFePO4 battery, from individual cells, your choice of BMS, etc.
If you can put one of those together & keep it going, you'll also be learning lots more than buying a "black box" solution.
YMMV.
Saw the thumbnail and thought it was Nvidia deal
Nyet - Voltax is Russian robot superhero.
so this battery is equivalent too 135,000 mAh battery?
Certainly will get few recharges for ones high end mobile phone 😀
@ 12V 135,000 mAh
@ 5V 324,000 mAh
Very juicy lolz
Depends on the regulator. Many cheapy 12-5V are linear so current in > current out.
Just like the new Liquid-Fuel, (NUCLEAR) Molten Salt Reactors that are due ~2029, they need reFueling every 7+ Years (unlike Fuel-Rod based dinosaurs used today, that must go offline (Read: "stop making baseload Electricity") [for weeks] for recharging (adding new Fuel-Rods, shifting partly-used ones around… a bit of a nightmare! ;~/
But I guess you may be right: A big 100 AH battery would keep your cellphone alive for yonks, ie, IF you have a trolly to pull it around on, or maybe get a job as a Lighthouse-Keeper, so you can leave it @ work ;~)
Tempted too get it just for the price, certainly come handy in lots of situations
I guess would be handy too in an UPS setup
Not in a cheap UPS setup no. These shouldn't be float charged, it ruins them over time.
Thanks,. certainly will come back here and see your post a no no in an UPS setup well seems like cheap UPS setup, im sure the UPS setup needs be of high grade similar too one would have as a home Solar battery setup with the right grade equipment
$500 with this seller also, I suspect all those accounts are probably Outbaxcamping, all at Regents Park:
https://www.ebay.com.au/itm/12V-135Ah-Lithium-Ion-Battery-Li…
Outbaxcamping use to have a fairly bad reputation, I assume they probably still do, very poor customer service and wildly exaggerated solar panel specs, and such, so there's a good chance these are nowhere near the claimed capacity…
@Flickit, 98% positive feedback from nearly 115,000 reviews…..can't be too bad?
Like a lot of the big ebay stores they have a nice ebay account manager that removes a lot of the negatives, it's quite common…
@FLICKIT: You sure they can unless its a negative cause somebody is trying too make that user account bad when it has nothing too do with the product they bought
Anyway my opinion one should always see what the negtive portion of the there bad rating is in this case 2% and see how many relates too a product one is buying, even when the negative portion is very very low say 0.01% bad portion too see if it relates too one product one is buying from the seller, well thats what I do when I'm looking at a sellers rating
@Italkdigital: It Happened when I negged a solar panel that was not described correctly and a piece of crap from this seller. Feedback was removed and it did not even upp the revised feedback count. Ebay well known for it.
@WV1: Wow ok I didnt realise eBay sellers can have an ebay account manager, I guess these big sellers must have special seller accounts or a subscription store as i can't understand for example how some seller stores have packages for computer systems priced way below one could like me buy heavily discounted parts and build myself and yet there prices are still lower, well they must barely be paying the 10% sellers fees, I use too sell built computers on eBay in the past but its not worth anymore for small timers like me,..
And have too say thanks too yous for your above posts, well yous certainly have good memories,. I guess yous love pointing out bad eBay sellers too the general public, well i would nothing worse then being stung when purchasingsomething, again big thanks
ps: I try too buy from small local eBay sellers especially those with great comments within there 100% postive ratings
edit: thanks too posts below too 😀
Outbax are shit - they shamelessly sell things they don't have in stock, things that estimate 2-3 days can take 3-4 weeks.
My bad, damn it I should have dug deeper.
Just be wary with what you plan to do with these. They have a max discharge rate of 50A (as do most of the cheaper lithiums).
125A
5 seconds @ 125A.
50A continuous.
Agree, low discharge, typical of low quality battery construction and/or cheap cells. 1 year warranty also suggests they have little confidence in their product. Given the claimed (minimum) cycle life of 2000 recharges (with no specified DoD) you'd expect they'd stand by the specs. Industry standard is at least 2 years and regularly more.
thats way too cheap!paid $1300 for 100ah last year.Enerdrive.
Chalk and cheese. You bought quality with excellent backup.
is this regular price for Voltax ?
Could this be installed in my empty spare battery bay in my land cruiser 200?
what do you use it for?
Just bought the cruiser but looking to slowly turn it into a camper, with fridge lights etc so will need a battery
you certainly can install this for that purpose
Better off buying a battery box, eg https://www.ebay.com.au/itm/Giantz-Battery-Box-12V-Camping-P….
Portable, no concerns about heat and cold and most have all the outlets you'll ever need.
@[Deactivated]: Never seen that before, don't most people put a battery in the spare compartment? Where would this box sit normally in the car? In the boot? Would you just plug a surge protected power strip into it to run fridge, lights etc?
@Archaleas: Unless you do it yourself, under bonnet (or ute tub, trailer etc) dual battery systems with isolaters etc recharged by your vehicle alternator are expensive to install, even for cheaper AGM batteries which can be regularly depleted somewhat for fridges etc. A battery box with an LiFePO4 (~$700 or about half the cost of a fixed system) can sit anywhere. Commonly used with solar panels for recharge when off grid for a few days+.
You simply plug the fridge, lights etc and the solar panels/blanket (with regulator) into the battery box. One draws power while the other recharges the battery. The fridge (cycling on and off) will draw very few amps even in hot conditions but obviously you need to calculate the draw against the battery capacity. Eg 2 amps for 24hrs = 48Ah, not that this is likely in most conditions.
Most 12v lithium batteries have a battery mgt system (BMS) which protects against too much draw etc. Good 12v fridges also have low battery cutouts (selectable). You can regularly take LiFePO4s to 100% DoD (depth of discharge) but for longer life ideally you want to leave about 20% capacity.
In general for a single battery setup you won't be able to run heavy amp drawing appliances from it using an invertor but it's ideal for fridge, lights, phone recharges etc. For shorter times away from power there are also things like this.
And your cruiser is gonna love one 👍
I'm gonna neg this based on serious issues with the retailer - these guys shamelessly sell things they don't have in stock and they can take 3-4 weeks to deliver when estimates provided are 2-3 days. It happened to me, and appears to have happened to heaps of others based on recent eBay feedback.
Buy from anywhere else.
I don't care much about negs but I did say in my post that I received the two batteries within 3 days to country NSW.
Nothing against you OP, but these guys are shifty
I was looking to buy a LiFePO4 battery recently, and was doing quite a bit of research online.
(I ended up getting a Renogy)
I'm pretty dubious of the mob behind Outbax / Mytopia / Edisons / AGR Machinery. (Google is your friend for looking into their earlier incarnation as AGR Machinery, and all the customer service horror stories.) (If someone can confirm they're the same company, that would be great — it looks a lot like Outbax is the same mob, but I don't know for sure)
While looking for reviews of the Voltax batteries, I found a bunch of dead links, which is weird.
Like, a forum would link to a blog post or a youtube video, but following that link goes to a 404 page — indicating the author decided to take down their review.
I wondered if this is because the company chases down and threatens people who post negative reviews?
I did find this bloke though, who bought four, and they were all bad:
https://www.youtube.com/watch?v=cRa_CgKML8Y
he did get them all replaced though — and while the replacements at least had about the right capacity, he determined that the battery-management system on them was (in his words) "garbage".
So….. yeah.. draw your own conclusions.
If you're curious, here's a link to a whirlpool thread: https://forums.whirlpool.net.au/archive/1283863
just noticed it weighs less than my 100ah Enerdrive,according to the description,135ah Voltax weighs 12.5kg,100ah Voltax weighs 9.5kg
my Enerdrive 100ah B-tec weighs 12.6kg.
Only starting to look into these to power a telescope (only need 35Ah really)… man this is expensive. Lead Acid is heaps cheaper. Just paying for the Lithium premium?
It's about weight, longevity and useable capacity. I believe lithium usually wins on all those metrics and generally works out cheaper in the long run.
how many charging cycles, though?
In the thousands for this chemistry usually, as opposed to hundreds for lead acid. Look after them and they can last over a decade and still be providing 80% capacity.
Ok yes understand someone stated above these can't be used for cranking as an acid battery can but could this get you out of trouble by charging your acid battery if your acid battery has gone flat (which usually kills the acid battery anyway)
Just justifying spending over $500 for one, I an see these type of batteries have many applications saying that I think a replacement acid battery for my Holden cruze is over $300 anyway so I think not a bad price in comparison to a car acid battery
Umm too I guess lithium batteries are not too happy with heat, would it be advisable too leave these in a car boot on a super hot summer day or these are designed better for heat over there smaller portable lithium battery counterparts, now im thinking (well consider when parked) Tesla cars have lithium batteries but then there's are under the vehicle not in a boot
edit: I guess too like all lithium batteries best keep it charged at over 20% to under 80% and try too discharge too 20% before recharging if you really wanna take care of one
Tesla's have a cooling loop in them but they're a different chemistry to these anyway. LiFePo batteries are a lot more stable, I don't think it's possible for them to have a problem with thermal runaway, but I might be wrong.
I could buy a portable 12V fridge/freezer for it I guess, that's another application for too justify buying one lol
edit: I'm thinking running it cool at all times might help holding longer charge and longevity 😀
As a previous holden cruze owner I'd strongly recommend you sell or trade the car asap 🤭
I've got the diesel version and its a mobile ashtray with various dints small damage so forth, so not worth selling it with over 250kms on the clock saying that she's still going strong,, its my i dont care vehicle someone steals it i wouldn't care lolz
So I got to ask which issue did you experience?
There's any number of compact and far cheaper emergency starter chargers out there for that purpose Itd. You can buy cranking LifePO4s if you're desperate to experiment. Research how they're best charged to maintain their lifespan and how that fits your vehicle's charging system before you do. If you're paying $300+ for a L-A Cruze battery then you're not trying.
Mines the diesel version needs high amperage crank battery
Plenty of options ~$200.
7.6KG ? that sounds a bit dodgy… (or an error)
Not as critical in LiFePOs, but yes you'd expect it to be 2kg+ more. Could be thin battery pack cases, small lightweight (not robust) BMS, lightweight wiring etc…
This guy does some excellent tests eg 120Ah "rated" (labelled) batteries actually being actually 105Ah, and battery dismantling: https://www.youtube.com/channel/UCoj6RxIAQq8kmJme-5dnN0Q
Unless you need one now best to wait, they are only going to get cheaper over time. Plenty of people replacing lead acid batteries that are still working fine, my suggestion is wait until you lead once kicks the bucket before spending any money.

Very interested into the 100ah (to fit battery box). Really wonder if their advertised capacity is realistic.
