Darfon

B12LF 12kWh LFP Battery

Model Number: B12LF
How much battery storage do you need? The Darfon B12LF is a 12kWh LFP battery cabinet, but if you need more, two B12LFs can be stacked for 24kWh of power. Even though the B12LF is 485 pounds, it has wheels so moving it around the installation site is quite easy. Since the B12LF uses LiFePO4 chemistry, it has a longer life span and is safer than other lithium chemistries.
