Product Introduction
The JS-LFP12.8V80Ah lithium iron phosphate (LiFePO4) starting battery is a high-performance upgrade designed to replace traditional lead-acid batteries, delivering superior starting power, faster charging, and exceptional durability. With a nominal 12.8V output and 80Ah capacity, it provides stable, high-current performance ideal for frequent engine starts in various conditions.
Featuring a built-in BMS with self-balancing function, it ensures consistent cell performance and extends overall service life. Its maintenance-free, eco-friendly design eliminates the need for regular upkeep, while the lightweight ABS housing (just 11.5kg, half the weight of lead-acid alternatives) enhances portability and installation convenience.
Core Advantages
High-Efficiency Starting Performance
Equipped with a 30C high current discharge rate and a maximum 1000A pulse discharge for 3 seconds, this battery delivers powerful, instant cranking power to start gasoline and diesel engines smoothly. Even in low-temperature environments down to -20℃, it maintains reliable starting capability, avoiding the sluggish performance common with aged lead-acid batteries.
Ultra-Fast Charging & Low Self-Discharge
Supporting a maximum 100A charge current, it reaches full capacity in approximately 1 hour, making it ideal for quick recharges between uses. With a self-discharge rate of less than 2% per month, it retains power effectively during long periods of inactivity, ensuring it’s always ready for use.
Long-Lasting Durability
Rated for over 2000 cycles at 80% depth of discharge (1C discharge/0.5C charge at 25℃), this LiFePO4 battery lasts 3–5 times longer than typical lead-acid batteries. Its robust construction resists vibration, dust, and moisture, ensuring stable performance in harsh conditions and reducing long-term replacement costs.
Wide Temperature Compatibility
Designed for versatile use, it operates across a broad temperature range: charging from 0℃ to 55℃, discharging from -20℃ to 60℃, and storage from 0℃ to 35℃. A BMS high-temperature cut-off at 65℃ provides additional protection, ensuring safe operation even in extreme environments.
