Our R&D team utilizes advanced CAD/FEA simulation to engineer custom battery enclosures matching exact DIN standards (Group 49 DIN H8, L5, 45B24, 55B24RS). Enclosures feature IP67/IP69K ingress protection, die-cast aluminum alloy or flame-retardant ABS/PC shells, and anti-vibrational internal damping matrices.
Integrated automotive BMS units continuously measure cell voltages, temperature gradients, and State of Charge (SOC) / State of Health (SOH). Featuring proprietary "Smart Re-start" technology, the BMS isolates 20% emergency reserve energy before full depletion, allowing the driver to jump-start the vehicle at the push of a button.
Utilizing specialized ultra-low internal resistance (<0.8 mΩ) LiFePO4 cells and large 4680 cylindrical formats, our automotive starter batteries deliver up to 2100 CCA. Nickel-copper composite busbars joined by continuous fiber laser welding minimize voltage drop during 300A-2000A transient ignition surges.
Manufactured in SGS-audited cleanroom facilities adhering to ISO 9001, ISO 13485, ISO 14001, and ISO 45001 standards. Every production batch undergoes 100% automated optical inspection (AOI), full-cycle charge-discharge validation, thermal shock testing (-40°C to +85°C), and UN38.3 vibration simulation.
The UFX4680 cylindrical cell represents the pinnacle of volumetric efficiency for electric vehicle battery packs. Featuring a 46mm diameter and 80mm height, this tabless-inspired internal geometry minimizes internal electrical resistance (DCIR < 1.2 mΩ). With a unit capacity of 15,000mAh at 3.7V nominal, these modules allow automotive engineers to construct high-voltage (400V/800V) EV battery packs with significantly fewer serial connections.
Engineered as a direct drop-in replacement for premium European and North American passenger cars, SUVs, and light trucks requiring DIN H8 / L5 form factors. Delivering an astonishing 2100 Cold Cranking Amps (CCA), this unit effortlessly turns over high-displacement internal combustion engines even at sub-zero temperatures. Built-in smart microprocessor BMS protects against short-circuiting, over-charging, thermal runaway, and deep discharge while featuring an integrated "Re-Start" button.
Designed for 24V commercial vehicle electrical systems, marine auxiliary power, and heavy industrial machinery. Utilizing high-stability prismatic lithium-ion cells encased in an insulated aluminum casing, this pack delivers high energy density combined with exceptional thermal stability. The integrated CANbus communication interface allows real-time telemetry streaming directly to vehicle ECU displays.
Utilizing robust 32140 steel-jacketed cylindrical cells arranged in a 4S4P structural configuration, this 12.8V 60Ah module provides unmatched physical durability against severe operational impact and continuous high vibration. The steel casing effectively suppresses radial cell expansion, ensuring long-term thermal integrity and extending cycle life beyond 4,000 deep discharge cycles.
