I am selling a 48vdc battery charger. This unit is heavy duty and would charge large off-grid 48vdc batteries or 48vdc lift truck batteries. Input voltages are 120vac/240vac or 2 poles of 208vac. This is a used charger but has lots of life left. It will float charge battery bank at desired voltage and won't over charge batteries to harm them. Compare at $700.00 or more for good quality charger.
