The next generation EVE Energy MB31 prismatic LiFePO₄ (LFP) cell delivers a nominal capacity of 314 Ah at 3.2 V, storing approximately 1,000 Wh per cell. Built for endurance, it boasts an impressive cycle life of up to 8,000 cycles, making it a reliable candidate for systems expecting a long operational lifespan

These cells feature very low internal resistance (≤0.18 mΩ), supporting efficient charging and discharging with minimal energy loss

With a 0.5 C continuous rating (~157 A) and 1 C (Burst) short duration 30s, they’re well-suited for demanding applications

Robust design elements include operating temperature ranges from –30 °C to 60 °C (discharge) and 0 °C to 60 °C (charge), and they come with safety certifications such as MSDS, UN38.3, CE

This newly released in 2024 next generation EVE 314ah 3.2v Prismatic LFP cell, has been verified by EVE Laboratory to be able to reach 8,000 cycles, this is due to novel manufacturing technology, the secret sauce of LFP chemistry has gone through multiple iterations, the quality of the Cathode and Anode materials has been improved, and it is now expected that under the right conditions, these cells can reach a lifetime of up to 20 years in perfect conditions

PRE ORDER VS SAME DAY SHIPPING

  • PRE-ORDER is pre payment, and it means you can secure a LARGE discount there are a few reasons we can do this.
  1. Shipping Costs from EVE to Hervey Bay is rather expensive
  2. If we can collate a large number of orders together, we can secure better shipping costs directly from EVE factory to your delivery address.
  3. If we can accurately order the right quantity of cells from EVE, the entire process is more efficient and also lowers the cost.

SAME DAY SHIPPING - Orders from stock means we need to pay the expensive Dangerous Goods shipping a second time to your address. This and the cost of holding the stock in storage and business related expenses add up quickly. We always prefer to get our customers the best value for money.

Process > Quality of cells. Directly purchased from EVE, with testing data > moved to our warehouse for packing into boxes of 4 or aseembly into our range of batteries. We can then negotiate with shipping companies to deliver the goods at the best rates available for DG.

SAME DAY means we ship it from our stock in Hervey Bay to you the same day. We call the courier after you make the order. You should receive the goods within a few days to all EAST COAST locations.

Warranty coverage is subject to compliance with the published specifications and operating guidelines. Any claim must include adequate documentation of system design, operating currents, voltage settings, and temperature conditions.

In our experience over the past five years, the vast majority of issues submitted for review have been related to operating conditions such as:

  • Operation outside recommended temperature ranges (too hot or too cold)

  • Excessive charge or discharge currents

  • Incorrect BMS or inverter programming

  • Low or high voltage settings outside specification

  • Installation or system configuration errors

These factors are user-controlled and are not considered manufacturing defects.

Automotive-grade (A+ Grade) cells are engineered for long service life when operated within specification. When correctly installed, programmed, and thermally managed, they are expected to perform reliably for at least the stated warranty period in the overwhelming majority of cases.

While hardware failure is theoretically possible, it is extremely rare. For this reason, warranty approval requires reasonable evidence that any failure resulted from a manufacturing defect rather than from environmental, electrical, or configuration-related factors.

Batteries are electrochemical systems that require appropriate thermal management and adherence to specified voltage and current limits. Where operating data cannot substantiate compliance with these parameters, liability cannot be assumed.

The vast majority of customers experience reliable, trouble-free operation. Proper system design, correct programming, and appropriate environmental control are the key factors in achieving this outcome.

TRADE PRICING, COLLECTION & FREIGHT TERMS

The advertised price is our Brisbane collection price. Collections are available on Thursdays only and must be arranged in advance.

Our pricing is based on the product cost plus the actual freight charge. For example, 16 units at $150 each, plus freight, will generally cost less than purchasing the same goods with “free shipping” built into the price.

Freight to regional and remote locations may attract a premium. This is a normal cost of transporting heavy Dangerous Goods into these areas. For larger orders, customers should consider collection from Brisbane or from the nearest suitable freight depot.

Freight quote requirements:

  • A commercial delivery address is preferred.

  • The receiving site must have suitable forklift unloading facilities.

  • Residential addresses or sites without a forklift may incur additional tail-lift and handling fees.

  • Where direct delivery is unsuitable or uneconomical, collection from a nearby freight depot may be required.

  • Customers are responsible for providing accurate delivery and unloading information when requesting a quote.

All lithium battery products are transported as regulated Dangerous Goods in accordance with the applicable UN 3480 transport requirements. Batteries are UN 38.3 tested where required, and compliant Dangerous Goods freight procedures are strictly followed.

These are trade freight arrangements for heavy battery products. Customers must ensure they have suitable access, unloading equipment or a practical depot-collection arrangement before ordering.

Tim Stokes
Awesome service. Very knowledgeable. I have bought a number batteries from them and great experience each time.
Robert Robins
Purchased a Growatt Spf5000es inverter, pricing was very competitive and service was great. Highly recommend
Bruno Drinovac
Purchased a Deye inverter from LiFePo4 in June 2026. I am pleased to say that the inverter has been running perfectly with no issues for the last 1½ months. It has been installed into an off-grid system on a very recently built granny flat. This inverter was ideal for our situation and was easy to set up. The 2 trackers were very handy as we needed to deal with 2 different sets of strings operating at 2 different voltages. It certainly looks like a very well designed and robust inverter and will hopefully last us many, many years. If and when we need to replace the inverters on the main house, we will certainly be looking at using Deye.
LiFePo4 provided free delivery, which was very quick, arrived in only a couple of days. They sent me an email checking on how we were going with the installation and offered assistance if we needed it. Excellent Company to deal with and I would purchase from them again in future.

Been buying batteries from LIFEPO4 Australia for years, always A grade! Great to deal with. Great after sales support. Recommend highly.
Russell Vosseler
Mark and the team have done a great job finding the best solar and battery solution for my house, my parents house, and also friends' houses.
Their batteries are top quality, not like the cheap and nasty ones you find with "special low deals". Best to pay a little extra and get quality products.
Their aftersales service is exceptional with continual support after installation. Mark had provided guidance months after installation to maximise the production of my inverter, and continues to provide valued suggestions even now. 😀
Ken Baker
just received my 30 jinko panels this morning...from initial enquiry to delivery in metro adelaide was 4 days!...on top of that LifePo4 beat the other quotes on price so needless to say I am very happy with the purchase. highly recommend
Steph G
I can’t speak highly enough of Mark at LiFePo4 Australia – they’ve now saved our motorhome adventure twice!
The latest drama hit when our battery failed mid-trip, leaving us in a power pickle. Even though it was outside business hours, Mark jumped on the phone and organised a replacement battery with lightning-fast turnaround.
This is the second time Mark has gone above and beyond for us – always friendly, knowledgeable and genuinely committed to getting you sorted. Couldn’t recommend them enough.
Response from LiFePo4 Australia

Thanks Steph. I'm glad we could assist. The cells you picked up before finding us at LIFEPO4 AUSTRALIA might have been B grade. We are glad we could help out with the 2 cells so far. If any of the others drop out, I'll send out replacements as quickly as we can. Enjoy your travels

Peter Demol
I had an excellent experience buying components to assemble 2 battery packs. Mark is extremely knowledgable about the products he sells. He answered all my questions, prices are excellent, and when there was a potential issue, he went over and above by supplying extra products at no extra cost. Shipping halfway across the country to a rural area took only 3 business days which is insanely fast. I am totally happy with my new batteries and with Mark's excellent customer service. After 10 years of FLA batteries, finally going to lithium technology is heaven. Thanks again Mark. Very happy customer.
Vicki Wattus
Awesome customer service, Mark went above and beyond in sorting my order when we ran into a few snags with it. I would recommend this company to anyone who values good price, service and a great customer experience.
Response from LiFePo4 Australia

It was my pleasure Vicki, we love helping out especially those who need a little bit of help. We hope your get years of service from the Victron MPPT and Jinko 510W solar panel, thanks for you patience over the weekend while we arranged the shipping for the panel to the depot nearest you. The $200 we saved on shipping, was well worth the delay over the weekend. Safe Travels Mark

Ray Carson
Absolute legend of an owner great 10 star customer service and product and knowledge to match..!!!
Not just a salesman...anything but absolute legendary service and knowledge to suit..
T R
Cells arrived, a bit of a delay. But overall we'll priced and packaged.
garry miille
Mark knows what he is talking about when it comes to batteries. Great pricing and very helpful too. Just a great experience all round.
Dapper Rausimen
I totally agree with the other 5 star reviews and can highly recommend buying lithium cells from this business. I received my order of 72 automotive MB31 batteries quickly and I am very impressed. All the cells were within 0.01 of a volt so didn’t require balancing or top charging before installing. They are the real deal A+ automotive grade EVE cells as advertised and not B grade rubbish some online sellers are supplying. Mark actually answers the phone if you need to discuss anything before purchasing and is one of the few people I have found selling lithium batteries that actually now’s about how to install and set voltage settings in the BMS’s he sells.
Elliot C
Super helpful gentleman. I barely prompted him and he gave me plenty of important and useful information. Best customer service I have had in as long as I can remember.
