The 25ah is a rechargeable lithium iron phosphate pouch cell with a nominal voltage of 3.2V and capacity of 25Ah. Its flat aluminum-plastic film construction provides a 9mm-thick format for custom battery assemblies. MisenBattery supplies this cell and supports pack integration for energy storage and backup power projects, subject to application qualification. The supplied specifications include 0.7mΩ internal resistance and a reported cycle life exceeding 3000 cycles.
01 25Ah Capacity for Custom Assemblies
A nominal capacity of 25Ah provides a practical basis for sizing custom rechargeable battery assemblies. Combined with the 3.2V nominal voltage, it gives approximately 80Wh of calculated nominal energy per cell. Final pack configuration should account for usable energy, operating conditions, system losses and the application’s required runtime.
02 Slim 9mm Pouch Format
The specified 9 × 133 × 203mm dimensions provide a flat geometry for evaluating stacked cell arrangements and space-constrained enclosures. Aluminum-plastic film forms the pouch enclosure. Mechanical integration should protect the cell body and tabs, with allowances for insulation, manufacturing tolerances and any support or expansion clearance required by the manufacturer.
03LFP Chemistry and 3.65V Charging Voltage
This cell uses lithium iron phosphate chemistry and has a specified charging voltage of 3.65V. These characteristics guide the selection of compatible charging equipment and battery management components. Charge-current limits, temperature restrictions and protection settings still require manufacturer confirmation; the charging voltage alone does not define a complete charging protocol.
04 Specified 0.7mΩ Internal Resistance
The supplied data lists an internal resistance of 0.7mΩ, providing a reference for technical evaluation and incoming inspection planning. The measurement method, temperature and state of charge are not specified. Confirm these conditions before comparing cells, and obtain separate continuous and peak current ratings before assessing suitability for demanding loads.
05 Approx. 163.3Wh/kg at Cell Level
Using the calculated nominal energy of 80Wh and the stated central weight of 490g gives approximately 163.3Wh/kg. The supplied cell weight tolerance is ±20g. This cell-level reference supports preliminary mass budgeting; a completed pack must also include the weight of protection electronics, interconnects, insulation, mechanical supports and its enclosure.
06 Reported Cycle Life Above 3000 Cycles
A cycle life exceeding 3000 cycles is reported in the supplied specifications, supporting consideration for repeated-use battery projects. The test temperature, charge and discharge rates, depth of discharge and capacity-retention threshold are not provided. Confirm the full test protocol before estimating service life or making comparisons with other cells.
Custom battery pack applications: MisenBattery supplies individual cells and supports custom pack integration for energy storage, backup power and other qualified rechargeable battery projects. Each pack requires a compatible BMS, fuse protection, voltage and temperature sensing, insulation, suitable spacing and appropriate thermal and mechanical design. Tab connections should use a manufacturer-approved process, including welded interconnects where applicable. Availability and scope of CE, UN38.3, RoHS and UL documentation must be confirmed for the exact product and shipment; certification is not established by the supplied parameter list.
