Description
The BSLBATT B-LFP48-100E is a 51.2V 100Ah (5.12kWh) LiFePO4 rack-mount battery built for off-grid systems, solar storage and backup power. Its 3U rack design fits standard server-style racks, and you get 100% usable depth of discharge, so the full 5.12kWh is available to your system.
It has 16 prismatic LiFePO4 cells (16S1P) managed by a built-in 100A BMS. It's rated for more than 6,000 cycles and a design life of over 15 years. RS232, RS485 and CAN communications let it talk to compatible inverters, and you can run up to 63 units in parallel for up to 322.56kWh of storage. That makes it suitable for anything from a single home or RV setup to a large commercial bank. Backed by Zero Grid's commitment to quality, it's ready to power your energy independence.
