It has been a while since EVE unveiled its new MB56 LFP cell. According to EVE, the lithium iron phosphate battery has a nominal capacity of 628 Ah and a voltage of 3.2 V. This corresponds to 2.01 kWh of electricity, which the new cell is said to be capable of storing. It is also reportedly remains stable over 8,000 cycles, enabling a particularly long service life. The manufacturer primarily envisages its use in ESS systems (energy storage solutions, such as photovoltaic systems or seasonal storage).
So far, nothing new. Also not new is the fact that countless offers for the new cells can be found online. However, information provided by retailers on Alibaba, Aliexpress and other platforms doesn't match the manufacturer's specifications, which raises the question of whether these are actually real models or merely imitations. Recently, reputable retailers such as the Dutch supplier nkon have also added EVE's MB56 to their product range.
The new cells in "Grade A" quality listed at a net price of €117.6. With "Grade A Minus", you can save some money; the dealer charges €106.68. However, since the manufacturer does not yet have the new cells in stock, shipping from the Netherlands is not expected until the end of October at the earliest.
Non-EU buyers can take a look at Gobel Power, which ships directly from China. A-Minus quality cells cost $108, but higher shipping costs and possible import fees should be expected. Furthermore, the delivery time is approximately 50 to 60 days.
Whether it even makes sense to use cells with such a high capacity at this point remains to be seen. Not only do these require more powerful or larger accessories such as BMS (battery management systems), balancers, fuses and compression housings, which are not yet widely available, but the cells themselves, with a net weight of 11.3 kg, are not exactly light. A 48-volt energy storage system with 16 of these cells easily reaches around 200 kg.
A test video of the new cell is embedded below.
