Rechargeable BMS 512V 75ah Lithium Ion Battery for UPS

>Ultra high volume energy density, saving footprint ≥50%

Using environment friendly high-density lithium iron phosphate cell, its volume energy density is 200-300Wh/L, which is 3-5 times that of lead-acid battery. And lithium battery can save more than 50% of the floorspace under the same condition,having more footprint for IT cabinet.

>Excellent fast charging ability, charging time is only 1/6 of lead acid

Lithium-ion batteries can be recharged within 1 to 2 hours to restore the backup power capacity of the UPS system and improve system security and stability, while lead-acid batteries take 10 to 15 hours.

>Smart BMS battery management system

Built-in intelligent battery management system to ensure a full range of real-time data collection, status monitoring, control and protection, remote monitoring and operation and maintenance of the battery, which improve the safety and reliable operation of the system. with over charge/over discharge/ short circuit/ high and low temperature alarm and protection function.

>Ultra high weight energy density, 70% lighter weight low load-bearing requirements on the floor

The weight energy density of lithium battery is 100-150 Wh/kg, and that of leadacid battery is 30-50Wh/kg. 70% lighter and 70% smaller than the VRLA batteries,save footprint and lessen the weight load and cooling consumption.

>Compact battery design minimizes the installation and maintenance cost

The compact battery size and less weight help minimize the initial installation and transportation cost compare to the lead acid batteries, also the maintenance cost and cooling consumption cost is reduced greatly because of it.

>Long service life and better TCO

The service life of lithium battery can reach 15 years which is 3-5 times longer than that of lead acid batteries. The TCO of lithium battery is only 50%~70% of that of lead acid batteries. Simplify operation and maintenance, reduce OPEX, and increase the service life of the entire power supply system.

Key features:
