Product Description
The EG4® 48V-LL-S rack-mounted lithium batteries are ideal for low-voltage energy storage
system applications. These batteries use lithium iron phosphate cells with the highest safety
performance and a battery management system (BMS) that can monitor and collect voltage,
current, and temperature of each cell within the module in real time. The BMS also contains a
passive balance function and an advanced battery control method, both of which can help
improve the performance of the battery pack. For enhanced security, the battery has two
onboard fire-extinguishing modules.
