The EVE C46PH-V1.1 is a rechargeable cylindrical LiFePO4 cell with a specified minimum capacity of 21Ah and minimum energy of 67.2Wh under the stated test conditions. Its published current limits include 8C continuous discharge and 5C continuous charge at 25°C. MisenBattery supplies cells and supports custom battery pack integration. The available manufacturer excerpt covers B-sample shipments; production suitability requires confirmation against the current complete specification.
The manufacturer excerpt specifies a minimum capacity of 21Ah and minimum energy of 67.2Wh, measured at 1C over 2.5–3.7V at 25 ± 2°C. These qualified values provide a reference for cell selection and pack sizing. Delivered pack capacity and usable energy depend on operating temperature, discharge rate, voltage limits and system losses.
A maximum continuous discharge rating of 8C at 25°C makes this cell a candidate for battery packs with substantial current demand. The standard discharge current is 1C at the same temperature. Pack designers must validate interconnects, protection settings and thermal behavior before using the maximum rating in an assembled system.
The excerpt lists standard charging at 1C and maximum continuous charging at 5C, both at 25°C. It separately specifies 20C pulse charging for 10 seconds at 50% SOC and 25°C. These are distinct operating limits; the pulse value does not describe a full charging cycle or establish a charging-time guarantee.
The supplied promotional graphic lists a cylindrical size of Ø46.8 × 146.4mm and a weight of 510 ± 10g. These figures support preliminary enclosure and cell-holder planning. Confirm the production drawing, dimensional tolerances, terminal geometry and connection requirements before finalizing fixtures, insulation clearances or interconnect tooling for a battery pack.
Initial DC resistance is listed as 1.4 ± 0.1mΩ in the supplied promotional graphic. The measurement SOC, temperature and timing are not provided, so this value should not be treated as directly interchangeable with AC impedance or other suppliers’ DCR results. Obtain the manufacturer’s test method before setting incoming inspection criteria.
Promotional data lists 13,000 cycles at 25°C and 5,000 cycles at 45°C, each to at least 70% capacity retention under stated 3C and 50% DOD conditions. These are partial-depth cycling figures, not full-depth cycle-life claims. Review the complete cycling protocol and production specification before estimating service life for a particular duty cycle.
Custom battery pack applications: Potential projects include light electric mobility, industrial equipment and AGV battery packs, subject to application-specific validation. MisenBattery supplies EVE cells and supports custom pack integration. System design should include a compatible BMS, fuse protection, voltage and temperature sensing, insulation, cell spacing, mechanical support and thermal management. Use manufacturer-approved welded interconnects where applicable. Confirm applicable CE, UN38.3, RoHS and UL documentation availability and scope for the exact cell, assembled pack and shipment; the supplied images do not establish certification.
