8000W High Power 48V battery chargers

More lead acid battery chargers 6V, 12V, 18V, 36V, 42V, 48V

Custom design and manufacture of state-of-the-art battery chargers, UPS, and power supplies for OEMs in a hurry!

120A 48V battery charger for golf carts and electric vehicles

Summary: This is a high efficiency switchmode charger based on the latest high frequency power supply design technology. This enables the charger to pack 8000 watts into a relatively small package. These are also available in other input and output voltages

Suggested Applications: Fast charging of flooded lead acid batteries and qualified VRLA batteries for fork lifts, club cars, golf carts, floats and other electric vehicles.

Application note: We have these installed in a luxury resort in the Seychelle Islands to provide fast-charge capablities to their golf-cart fleet, providing 2-3 hour turn around.
