LiFePO4 stands for Lithium Iron Phosphate. This lithium chemistry is particularly well suited to applications where low weight, good cycle life, stable voltage characteristics and dependable rechargeable performance are important.

Compared with traditional sealed lead-acid or AGM batteries, lithium technology can provide a significantly lighter battery solution while providing the required 12V system voltage for compatible golf trolleys.

• MUCH LIGHTER: At approximately 2.2kg, this UltraMax lithium battery is considerably lighter than many conventional lead-acid golf trolley batteries.
• EASIER TO CARRY: The reduced battery weight makes lifting and transporting the golf trolley and battery easier.
• MORE USABLE ENERGY: Lithium batteries can generally utilise a greater proportion of their rated capacity than lead-acid batteries.
• BETTER VOLTAGE CHARACTERISTICS: LiFePO4 batteries generally maintain a more consistent voltage during discharge compared with traditional lead-acid batteries.
• LONGER POTENTIAL SERVICE LIFE: Correctly maintained LiFePO4 batteries can offer significantly more charge/discharge cycles than many conventional lead-acid batteries.
• LOWER SELF-DISCHARGE: Lithium batteries generally retain their charge better during periods of storage.
• NO ACID SPILLING: LiFePO4 technology does not use the liquid sulphuric-acid electrolyte found in conventional flooded lead-acid batteries.
• MAINTENANCE FREE: There is no electrolyte topping-up required.
• USB CHARGING: The built-in USB port provides an additional source of power for compatible USB devices.
• MODERN LITHIUM TECHNOLOGY: Provides a convenient upgrade path for compatible 12V electric golf trolley systems.

• Specialist battery brand: UltraMax specialises in rechargeable battery solutions for many applications including golf trolleys.
• LiFePO4 chemistry: Uses Lithium Iron Phosphate technology.
• Integrated BMS: The Battery Management System helps manage and protect the lithium battery during normal operation and charging.
• Golf trolley specific design: Designed as a replacement battery for compatible electric golf trolley applications.
• Built-in USB: The USB facility is integrated into the battery rather than requiring a separate power bank.
• Lightweight: Approximately 2.2kg.
• Compact: 168mm x 128mm x 75mm.
• Complete golf battery solution: Battery, charger, battery bag and appropriate connection arrangement are supplied according to the advertised package.

One of the most useful features of this UltraMax battery is the built-in USB charging port.

When playing golf, your mobile phone, GPS device or other electronic equipment may lose charge during a long round. The built-in USB port gives you the convenience of having a USB power source directly on your golf trolley battery.

Typical uses include:

• Charging a mobile phone
• Charging a golf GPS device
• Charging compatible GPS accessories
• Charging compatible USB-powered equipment
• Keeping your phone charged while using GPS/navigation
• Keeping your phone available for emergency calls

This can eliminate the need to carry a separate power bank for many everyday USB charging requirements.

IMPORTANT: The USB output should only be used with compatible USB-powered devices. It is not a replacement for the main golf trolley battery output and should not be used to power equipment requiring a different voltage or charging system.

This UltraMax 12V 18Ah LiFePO4 battery is designed as a universal-style replacement for many compatible 12V electric golf trolley systems.

It is particularly suitable for customers looking to replace an existing compatible lead-acid, AGM, SLA or lithium golf trolley battery with a lighter lithium solution.
