Yunfan YF12V6Ah-LAS is a compact 12.8V 6Ah lithium iron phosphate battery designed as a direct replacement for traditional 12V small lead-acid batteries. It addresses common weaknesses of lead-acid batteries including short cycle life, frequent maintenance requirements, acid leakage risks, and poor low-temperature performance.
Equipped with a full-function intelligent BMS, it provides multi-layer protection against overcharge, over-discharge, and overcurrent, along with automatic cell balancing to extend service life. The sturdy ABS+PC shell with IP55 rating ensures dust and splash resistance, operating steadily from -20℃ to 60℃ and achieving over 5000 cycles at 0.3C rate.
Lithium iron phosphate cells provide stable thermal performance, effectively avoiding leakage and safety risks associated with traditional lead-acid batteries.
Real-time cell monitoring triggers multi-level safety protection with automatic cell balancing to slow capacity attenuation during long-term cyclic use.
Standard outer dimensions match common 12V small lead-acid batteries, requiring no cabinet modification for quick retrofit installation.
Durable ABS+PC casing blocks dust and moisture intrusion, suitable for indoor equipment rooms and semi-protected installation environments.
More than 5000 complete charge-discharge cycles under standard 0.3C working conditions, significantly reducing long-term replacement costs.
Maintains stable discharge performance at -20℃ low temperature, fitting all-season indoor and mild outdoor low-power backup equipment.
