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 high-current 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.
