LiFePO4 Lithium Battery Pack
Due to the demand for energy saving strategies, LinkData Technologies delivers a full range of battery power systems with multiple nominal voltages (12V/24V/48V/240V/etc.). This product is small in size and light in weight, it has longer cycle life, temperature adaptability is stronger, and energy storage is more efficient. With the accurate and reliable battery management system (BMS), our lithium battery power system is a better solution for achieving high efficiency and reliability. After years of practice, we have the most extensive experience in backup power supply in the industry, and we will continue to provide the best battery products.
Features
- Energy density is high. The volume and weight of lithium battery is 1/3 to 1/4 of the traditional lead acid battery with the same capacity.
- Energy conversion rate is 15% higher than that of a traditional lead acid battery, the advantage of energy saving is obvious.
- Self-discharge rate < 2% per month.
- Broad temperature adaptability. Products perform well at a temperature of -20°C to 60°C, without air conditioning system.
- Cycle durability for a single cell is 2000 cycles, which is 3 to 4 times more than the cycle durability of a traditional lead acid battery.
- Higher discharge rate, faster charging and discharging. When there is a need for backup power supply for a period of 10 hours or less, we could reduce up to 50% of the capacity configuration, comparing to lead acid battery.
- High security. Our lithium battery is safe, electrochemical materials are stable, no fire or explosion under extreme conditions such as high temperature, short circuit, drop impact, piercing, etc.
