What to confirm when sourcing EVE MB31
MB31 is listed as a 314 Ah individual prismatic cell. When reviewing it for an existing design, confirm the applicable specification revision, terminal arrangement and physical fit. A larger nominal capacity does not by itself establish compatibility with a different cell model.
The MB31 description includes power-based charge and discharge figures. Keep their original units and test conditions when comparing them with current-based ratings on other pages; do not treat a P rating as an identical C rating. Ask for the specification relevant to the proposed cells and your operating requirements.
Include the quantity, application, destination and required acceptance records in your inquiry. Sample conditions, minimum order quantity, pricing, current availability, lead time and the inspection or compliance documents that can be provided are confirmed during the inquiry.
Compare the 280 Ah LF280K and 304 Ah LF304 using our EVE LiFePO4 cell sourcing guide. Contact Raysun about MB31 to confirm the quotation details.
For MB31, confirm the applicable batch specification, current availability, sample policy, minimum order quantity, lead time and available inspection or compliance documents during inquiry. Supporting batch documents are provided as applicable to the inquiry.
The public catalogue and the downloadable reference may describe different revisions. Confirm the specification and operating limits applicable to the proposed batch before selecting the cell.
MB31 document and operating-condition questions
Is the MB31 PDF a pack specification? No. The reference is for an individual MB31 cell. It does not establish the finished pack voltage, connection layout, enclosure fit or control settings for a particular project. Match the cell specification revision and terminal drawing to the design being quoted.
Does 0.5P mean the same thing as 0.5C? No. This listing records standard charge/discharge power as 0.5P, with the stated 502.4W reference. Power-based and current-based test conditions should retain their original units when comparing MB31 with another model.
Does the cycle figure guarantee service life? The 8000-cycle, 70% state-of-health reference must be read with the applicable test procedure. Request that procedure and the specification for the proposed batch before using the reference in a project calculation. Sample terms, availability and supporting batch records remain inquiry-confirmation items.
