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 NOCO Genius GX4820 is a 48 V / 20 A onboard industrial battery charger designed to handle heavy-duty applications in electric vehicles including golf carts, pallet jacks, scissor lifts, floor scrubbers and other utility/industrial equipment.
• With its universal input (100-240 VAC, 50-60 Hz), this charger supports global power grids while maintaining exceptional performance and compatibility. 
• It delivers up to 960 W of power and operates at approximately 92% efficiency, ensuring fast, energy-efficient charging that reduces cost of ownership and downtime. 
• Engineered for flexibility, the GX4820 supports both lead-acid (wet, gel, AGM, EFB, CA) and lithium-ion battery chemistries, making it a versatile solution across battery technologies. 
• It’s rated for battery capacities up to 425 Ah, providing ample capability for deep-cycle battery banks and larger 48 V systems. 
• Rugged, sealed construction with IP66 ingress protection and resistance to oil, gas, grease, water, UV, chemical and abrasion makes this charger ideal for harsh industrial and outdoor environments. 
• Smart charging technology includes advanced modes such as “Repair” mode for sulfated or idle batteries, “Supply” mode for use as a DC power supply, and diagnostics like reverse polarity protection and spark-proof operation for added safety.
• Includes long 76-inch AC and DC cables with integrated eyelets and plug-in connections, making installation simple whether you’re using it onboard or offboard — mount it on a wall or vehicle chassis. 
• Suitable for both on-board (mounted directly on equipment) and off-board (stand-alone charger) applications, offering flexibility in how you deploy charging systems. 
• Backed by a 1-year limited warranty, you can trust that this charger meets professional standards for reliability and manufacturing quality. 

Why this charger stands out:

• A plug-and-play industrial charger built by a trusted brand in battery charging solutions.
• One charger covers multiple battery chemistries and sizes — no need for separate lead-acid vs lithium chargers.
• Rugged IP66 housing ensures dependable performance outdoors or in rough equipment environments.
• Smart modes help recover damaged batteries and maintain them long-term, which helps extend fleet battery life and reduce replacement costs.
• Global input voltage and universal cables make this a practical choice for both domestic and international deployments in golf cart fleets, material handling equipment, industrial vehicles, and more.

Ideal applications include:

• Charging 48 V golf cart battery banks, in both fleet and recreational use.
• Industrial lift equipment such as scissor lifts and pallet jacks that use 48 V battery systems.
• Floor scrubbers and utility vehicles in manufacturing, warehousing or logistics operations that require reliable 48 V charging.
• Workshops or service centers requiring a rugged on-board or mounted charger for maintenance bays or vehicle hangars.

Equip your fleet or industrial equipment with a charger that delivers professional-grade performance, flexible compatibility and rugged durability. The NOCO Genius GX4820 is designed to reduce downtime, protect your batteries and support a wide range of 48 V systems under demanding conditions.
