Key Takeaways
1. EVE’s MB56 LFP battery cell has a capacity of 628 Ah, operates at 3.2 V, and stores approximately 2.01 kWh of energy.
2. The battery is designed for long-term use, maintaining stability over 8,000 charge cycles.
3. Retail prices for “Grade A” cells are €117.6, while “Grade A Minus” cells are priced at €106.68, with shipping starting later in October.
4. Buyers outside the EU can purchase from Gobel Power, with “A-Minus” cells costing $108 but facing higher shipping and potential import fees.
5. The high capacity of these cells requires robust components and weighs 11.3 kg each, leading to significant overall weight for energy storage systems.
It has been some time since EVE introduced its latest MB56 LFP battery cell. According to the company, this lithium iron phosphate battery features a nominal capacity of 628 Ah and operates at a voltage of 3.2 V. This means it can store approximately 2.01 kWh of electrical energy. Additionally, it is claimed to maintain stability over 8,000 charge cycles, which suggests a notably long lifespan. The manufacturer primarily envisions this cell for use in energy storage solutions (ESS), including solar power systems or for seasonal energy storage.
Retail Availability
So far, there’s nothing particularly surprising. It’s also not new that numerous listings for these cells can be found online. However, the details provided by sellers on platforms like Alibaba and Aliexpress often do not align with the specifications given by the manufacturer, leading to questions about whether these are authentic products or just copies. Recently, reputable suppliers, including the Dutch retailer nkon, have also added EVE’s MB56 to their offerings.
Pricing Details
The new “Grade A” cells are priced at €117.6 net. For “Grade A Minus” cells, customers can save a bit, with a price of €106.68. However, as the manufacturer has yet to stock these new cells, shipping from the Netherlands is unlikely to begin until the end of October or later.
For buyers outside the EU, Gobel Power is an option that ships directly from China. The “A-Minus” quality cells are available for $108, but expect higher shipping costs and potential import fees. Moreover, the delivery timeframe is around 50 to 60 days.
Considerations for Use
Whether it makes sense to utilize cells with such a high capacity at this stage is still uncertain. Not only do these require more robust or larger components like battery management systems (BMS), balancers, fuses, and compression housings—which are not yet widely accessible—but the cells themselves weigh a net of 11.3 kg, making them quite heavy. A 48-volt energy storage system consisting of 16 of these cells can easily weigh around 200 kg.
