Top 60145 3.2V 50Ah LiFePO4 Battery Manufacturers in China
The VTCBATT 60145 3.2V 50Ah LiFePO4 battery cell is a large-format cylindrical rechargeable cell rated at 160Wh. It measures 60.35 ± 0.50mm in diameter and 145.83 ± 0.50mm in height, with a typical weight of 920 ± 15g. Standard charging is 1C (50A) CC/CV to 3.65V with a 0.05C cutoff, while standard discharge is 1C (50A) to 2.5V. The specification also permits short-duration currents up to 150A charge and 250A discharge, explicitly for instantaneous use rather than repeated cycling. Internal impedance is ≤0.8mΩ at 1kHz, and the cell operates from 0°C to 50°C during charging and −20°C to 50°C during discharge. At 0.5C, capacity retention to 80% of initial capacity is specified for at least 3,000 cycles; at 1C, at least 2,000 cycles. VTCBATT supports factory-direct cell supply, sample evaluation, matched-batch production, custom tabs and pack integration, OEM/ODM development, and wholesale quantities for equipment manufacturers and energy-storage assemblers.

Application for 3.2V 60145 50Ah LiFePO4 battery
The 60145 LiFePO4 cylindrical cell is suited to solar storage banks, telecom backup cabinets, industrial energy-storage modules, RV auxiliary systems, marine service power, UPS cabinets, low-speed electric platforms, AGVs, and robotics power systems where a durable 3.2V cell with 50Ah capacity is appropriate. Its cylindrical metal-can format, 160Wh rated energy, low internal impedance, and supported 1C standard charge/discharge profile make it practical for series-parallel battery modules designed with a suitable BMS, thermal management, insulation, and welded interconnects. VTCBATT can support application-specific tab configuration, busbar and welding requirements, matched-cell grouping, pack voltage and capacity design, BMS selection, enclosure integration, labeling, sample testing, and stable batch production. Factory-direct battery wholesale service is available for distributors, brand owners, system integrators, and equipment manufacturers, with final pack design validated against the device load, duty cycle, operating temperature, and charging strategy.

Cell size and structure
The cylindrical cell has two terminals on a black end face and a blue insulating wrap. Direct soldering to the cell is prohibited; tabs or busbars should be spot welded before lead connections are made. Battery modules require insulation that prevents wire-to-cell short circuits.

Charging, discharge and cycle performance
Standard charging uses 50A constant current followed by constant voltage at 3.65V until current falls to 2.5A. Standard discharge uses 50A to 2.5V. The cell is specified for at least 3,000 cycles at 0.5C and at least 2,000 cycles at 1C, in both cases measured to 80% of initial capacity. The maximum 150A charge and 250A discharge ratings are instantaneous values and should not be treated as continuous cyclic limits.
Temperature and retention
Charging is specified from 0°C to 50°C and discharging from -20°C to 50°C. At -20°C, the 1C discharge test to 2.0V specifies at least 80% capacity retention. Room-temperature storage for 28 days specifies at least 96% capacity retention and at least 97% recovery; the 60°C seven-day test specifies at least 94% retention and 95% recovery.
Application fit
Suitable engineered uses include solar and industrial energy-storage cabinets, telecom backup, UPS modules, RV and marine auxiliary systems, low-speed electric utility platforms, robotics and AGVs. Final suitability depends on pack voltage, load profile, environmental controls, BMS limits and mechanical integration.
OEM/ODM supply
VTCBATT supports cell samples, matched-cell grouping, tab and busbar requirements, welded interconnect design, BMS integration, enclosure development, private labeling and stable wholesale batch supply. Equipment manufacturers should validate the finished pack under the intended current, temperature, vibration and charging conditions.
