Model 7058 is designed to meet the emerging need to charge lithium 48V battery
banks from 24V systems. Model 7058 will output 25A @ 58V in full charge mode
and can be operated while load is drawn from the battery bank being charged. Off
the shelf units are ideal for use with lithium iron phosphate batteries. Model 7058
is microprocessor controlled and can be programmed at factory for operation with
other battery types.
