NOCO 48V 20A Industrial Charger

The GX4820 is a high-frequency, high-efficiency industrial battery charger for electric vehicles, like a golf cart, scissor lift, pallet jack, floor care machine or utility vehicle. It represents the latest technology for fast and efficient battery charging with multiple charging modes at a push of a button. It's universally adaptable design allowed for global use with replaceable A/C and D/C cables and designed for all types of deep-cycle lead-acid and lithium-ion batteries. And suitable for both on-and-off board applications.

The Next Generation Of Charging Electric Vehicles

Not only can it charge a wide-range of deep-cycle lead-acid and lithium-ion batteries, but it's as simple as a push of a button - no dip switches or downloadable software. And it's paired with a robust battery repair method to combat battery sulfation and recover lost battery capacity, plus easily converts to a constant current, constant voltage power supply for zero voltage charging or equalizing unbalanced batteries.

Universally Adaptable

A versatile industrial battery charger designed for worldwide use. Its internal magnetics and power design handle a wide-range of input voltages from 100-240VAC and frequencies from 50-60Hz. And with its removable A/C and D/C cords, it’s simple to change cables for each country or application - all in a water-resistant strain relief clamping system.

92% Efficiency

With over 960-watts of pure power, the GX Series uses incredible thermodynamics to deliver the most compact, yet powerful industrial battery charger ever. Rather than only using heat sinks, we designed a precision aluminum unibody that maximizes not only airflow but also thermal capacity.

New Industry Standard

An industrial battery charger that's designed to last even the most rugged and harsh operating environments. Whether used as an on-board or off-board battery charger, its robust aluminum unibody design withstands shock and vibration for endless hours of operation. Its over-molded strain reliefs prevent unwanted stress on the cables while providing a water-resistant seal.

Advanced Diagnostics

Smart industrial battery chargers can be frustrating. They do not simply begin charging upon detecting a weak or damaged battery. Sometimes they will begin force charging if they detect an unsafe or abnormal charging condition. But prevention is just one aspect. Understanding and finding a solution is just as critical. Welcome to Advanced Diagnostics, which analyzes battery feedback and display a particular error pattern if a problem is detected. Each flash pattern tells you what's wrong, and how to quickly fix it.

Single Flash: Battery will not hold a charge and should be checked by a professional.
Double Flash: Possible battery short, and should be verified by a professional.
Triple Flash: Battery voltage is too high for the selected charge mode. Double check the battery matches the charge mode.
Error LED Solid Red: Reverse polarity. Reverse the connections to the battery.
Standby LED Solid Orange: Battery voltage is too low for the battery charger to detect the battery.
