The Amptron® 48V 75Ah LiFePO4 battery is a direct drop-in replacement for the lead-acid bank in standard 48V electric golf carts, utility vehicles, and light electric mobility platforms. At 3,840Wh of fully usable capacity from a single 51.2V native unit, it eliminates the complexity of wiring four to six separate 12V batteries in series and delivers genuine two-round golf course range on a single charge. The 75A continuous and 200A peak discharge handles the sustained draw of 48V electric motors and the high startup current of heavily loaded carts on hilly terrain without BMS cutout. The aluminium-cased prismatic cells, IP65 sealed ABS enclosure, and built-in BMS with automatic cell balancing make it a long-term investment rated for 2,000+ cycles at 100% DoD and up to 5,000 cycles at 80% DoD. Compact, sealed, zero-maintenance, and a fraction of the weight of the lead-acid bank it replaces.

Features

AMPTRON® batteries come with a 4 year warranty and are designed using only the highest quality components. This includes the use of a robust Battery Protection System (BPS), aluminium encased prismatic cells, solid busbar connectors and a solid frame to reduce movement and damaging vibrations.  AMPTRON® batteries can also be placed on its sides without the risk of components coming loose or loss of usable capacity.

Our Lithium batteries use a high quality robust integrated Battery Protection System (BPS) and is designed to manage and control all the battery protection requirements. The BPS maximisers the performance of the battery by automatically balancing the cells and protecting them from being over charged or over discharged. Our integrated BPS design is what allows our batteries to be used as an AR "Alternative Replacement" for many applications requiring durable, high quality, dependable and lightweight Lithium Batteries.

Heavy Duty - Built In Battery Protection System

AMPTRON® lithium batteries have a built-in Battery Protection System (BPS) designed to prevent damage to the cells from almost any external accidental occurrence that would normally cause damage. The internal BPS will automatically disconnect to prevent damage to the cells if the battery drains below 10 volts. It will automatically reconnect when the charger is turned on. This protects the battery from over-discharging and damaging the cells. This technology also protects the battery from overcharge, short circuit and reverse polarity.

Internal Features:

• Low Voltage Protection Switch - Automatically disconnects around 10V
• Over Voltage Protection Switch - Automatically disconnects around 14.8V
• Short Circuit Protection Switch - Automatically disconnects
• Reverse Polarity Protection Switch - Automatically disconnects
• Internal cell balancing   - Automatically balances cells
• Charge Balancing - Independent balancing for multiple batteries connected in parallel or in series.
• This Battery Protection System is designed to last throughout the life of the battery and provide reliable power for thousands of cycles.

CELL BALANCING
The BMS balances the cells by sending more current through the length way circuit boards and into cells with a lower voltage. The BMS will also discharge cells that exceed 3.65V during charging.

THERMAL FUSE
Internal Cell Safety Fuse
Our latest cell technology is manufactured with a internal thermal safety fuse between the anode and cathode that will break and disconnect in the unlikely event the cell would begin to overheat.
 
SAFETY VENT
High pressure safety vent
Each cell has a high pressure safety vent that will flip open to release energy and prevent explosion.
 
ELECTROLYTE
Flame Retardant Electrolyte
Our cells are manufactured with our patented flame retardant additive in our electrolyte.
 
EXPLOSION PROOF
Explosion proof Nickel plated steel
Every AMPTRON® cell is manufactured in our explosion proof Nickel plated steel Prismatic case.

Usecases

The Amptron® 48V 75Ah LiFePO4 is engineered for 48V electric motor applications where a single high-capacity lithium unit needs to replace a bulky, high-maintenance lead-acid bank. Its native 51.2V architecture, IP65 sealing, and 200A peak discharge make it the practical upgrade choice across golf, recreation, commercial utility, and light industrial 48V platforms.

1. Golf Carts — Club Car, EZ-GO, Yamaha & Compatible Brands

The primary use case this battery was designed for. A single 75Ah unit replaces the full lead-acid bank in most standard 48V golf cart platforms.

• Two Rounds on One Charge: 3,840Wh of stored energy comfortably covers two full 18-hole rounds on a standard course under normal conditions — the benchmark most golf cart operators use when evaluating battery upgrades.
• Consistent Motor Performance: LiFePO4's flat discharge curve delivers full motor voltage and torque through the entire second round, unlike lead-acid which suffers progressive power loss from the halfway point onward as cell voltage sags under load.
• Massive Weight Reduction: At 35kg compared to 90 to 120kg for a typical six-battery 8V lead-acid bank, the Amptron 75Ah dramatically lightens the cart, reducing turf damage, tyre wear, and energy consumption per kilometre.
• Zero Maintenance for Fleet Operators: No cell watering, no acid equalisation, no terminal corrosion cleaning. For clubs managing 30 to 100 cart fleets, eliminating lead-acid maintenance represents a significant ongoing labour and cost saving across the season.

2. Resort, Estate & Campus Utility Vehicles

For 48V utility vehicles used in resort transport, airport ground support, retirement estate mobility, and industrial campus logistics where daily cycling and reliability are the primary requirements.

• Daily Cycle Durability: Rated for up to 5,000 cycles at 80% DoD, this battery supports continuous daily operation for years without capacity degradation that would reduce vehicle range or operational usefulness.
• Fast Turnaround Charging: Unlike lead-acid which requires a complete multi-stage charge cycle before safe reuse, LiFePO4 accepts partial charges during breaks or meal periods, reducing fleet downtime and eliminating the need for spare battery swap systems.
• Weatherproof for All-Day Outdoor Use: IP65 sealing protects the battery during wet weather operations, course irrigation, and outdoor wash-down cleaning of the vehicle without requiring battery removal or covering.
• Lower Total Fleet Cost: Despite higher upfront cost, 5,000 cycles at 80% DoD versus 300 to 500 cycles for lead-acid makes the long-term cost per kilowatt-hour substantially lower for fleet operators replacing batteries every 1 to 2 years.

3. Electric Utility & Tow Vehicles for Industrial Sites

For 48V electric tuggers, tow tractors, and light material handling vehicles in warehouse, airport, and manufacturing environments where the battery must survive demanding daily shift use.

• Sustained Motor Draw Capability: 75A continuous handles the sustained draw of 48V tow motors and electric tuggers under light to moderate loads in flat warehouse environments throughout a full work shift.
• 200A Peak for Load Handling: The 200A peak discharge handles the startup current spike when pulling loaded carts from a standstill or navigating loading dock ramps at low speed under load.
• Compact Form Factor for Existing Bays: The 520 x 268 x 228mm footprint fits into the battery trays of many 48V industrial tow vehicles designed for standard-format deep-cycle battery modules without tray modification.
• Reduced Handling Risk: At 35kg versus 90 to 120kg for an equivalent lead-acid bank, single-person battery removal and installation for charging or swap is significantly safer and faster, reducing manual handling injury risk.

4. 48V Off-Grid Solar & DC Power Storage

For small to medium 48V off-grid solar systems, remote monitoring stations, and telecommunications shelters where a compact, sealed, single-unit 48V storage solution is preferred.

• Native 48V Architecture: At 51.2V nominal, this battery operates directly with 48V MPPT solar charge controllers and 48V inverter-chargers without requiring a step-up converter, simplifying system design and reducing conversion losses.
• 3,840Wh for Moderate Off-Grid Loads: Sufficient stored energy for a remote cabin or monitoring station running LED lighting, communications equipment, a small refrigerator, and data acquisition hardware for several days without solar input.
• IP65 for Remote Enclosure Deployment: Suitable for installation inside weatherproof outdoor electrical enclosures at remote solar sites, telecommunications nodes, and environmental monitoring stations.
• Long Storage Retention: Retains 80% or more of capacity for up to 12 months, making it suitable for seasonal or infrequently accessed remote installations where the battery may sit idle between site visits.

5. Electric Mobility & Specialised 48V Platforms

For electric wheelchairs, powered mobility platforms, and specialised 48V recreational or commercial vehicles that use standard deep-cycle battery footprints.

• Lighter Device, Greater Range: Removing 55 to 85kg of lead-acid battery weight from a mobility platform dramatically improves range per charge, handling responsiveness, and the practical portability of the device for transport and storage.
• Consistent Power to the Last Percent: LiFePO4 flat discharge maintains motor controller voltage within specification right through to low charge, unlike AGM batteries that cause progressive speed and hill-climbing performance loss in the final 30% of discharge.
• Versatile Mounting Orientation: The sealed ABS enclosure allows installation upright or on its side, giving platform designers flexibility in fitting the battery to existing tray configurations designed for differently oriented lead-acid modules.
• Simplified Charging Infrastructure: One 48V LiFePO4 charger replaces the multi-charger setup previously needed for individual lead-acid cells, reducing charging station complexity and energy consumption for facility operators.
