The Amptron® 24V 50Ah LiFePO4 battery is the smart, direct replacement for the 24V deep-cycle lead-acid, AGM, or GEL battery that's been slowing your setup down. Whether you're upgrading a golf cart, powering a mobility scooter, running a 24V trolling motor on your tinnie, or storing energy from a compact off-grid solar array, this battery delivers 1,280Wh of fully usable capacity in a 13.5kg package that a standard lead-acid unit can only dream about. The built-in BMS handles all protection and cell balancing automatically — there's nothing to water, nothing to equalise, and nothing to clean. Just a reliable 24V power source that charges faster, lasts longer, and works harder than the battery it replaces. Backed by a 4-year Australian warranty and available from Amptron's Australian-based team.
Features
These batteries are designed using only the highest quality components and are backed with our 4-year warranty. This includes the use of a robust Battery Management System (BMS), Aluminium encased prismatic cells, solid busbar connectors and internal protection to reduce movement and damaging vibrations. Our batteries can also be placed on their sides providing versatile installation options.
The integrated Battery Management System is designed to monitor, protect, and optimise each cell within the battery. The BMS maximises the performance of the battery by automatically balancing the cells and protecting them from over charging, over discharging, over temperature, and excessive charge or discharge currents. Our integrated BMS allows our batteries to be used as an alternative replacement for most applications requiring deep cycle batteries, however if the charging system does not support a Lithium charge profile, there are some compromises – please contact Amptron for more information.
HEAVY DUTY – BUILT IN BATTERY MANAGEMENT SYSTEM
AMPTRON® Lithium batteries use a built-in Battery Management System (BMS) designed to automatically disconnect the charging or discharging circuits to prevent damage to the cells and internal electronics from abnormal operation and helps to ensure safe and accurate operation of the battery.
THE BMS PROTECTION FEATURES INCLUDE:
Low Voltage Protection Switch – Automatically disconnects the discharge circuit to prevent damage to the cells if the battery drains below a pre-set voltage.
Over Voltage Protection Switch – Automatically disconnects the charging circuit to prevent damage to the cells if the battery is being charged above a pre-set maximum voltage.
Short Circuit and Over Current Protection Switch – Automatically disconnects the discharge circuit if the load draws currents above pre-set limits.
Reverse Polarity Protection Switch – Automatically disconnects the charge and discharge circuits if a reverse polarity condition is detected.
Thermal protection – Built-in thermal sensors will automatically disconnect the charge and discharge circuits when excessive temperatures are detected.
CELL BALANCING
The BMS balances the cells through top-end balancing and will discharge cells that exceed 3.65V during charging.
INTERNAL CELL SAFETY
THERMAL FUSE: Our latest prismatic cell technology is manufactured with an 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: Each cell has a high-pressure safety vent that will flip open to release energy and prevent explosion.
FLAME RETARDANT ELECTROLYTE: Our cells are manufactured with a flame retardant additive in our electrolyte.
Usecase
The Amptron® 24V 50Ah is engineered as a direct, zero-modification replacement for 24V deep-cycle lead-acid batteries across a wide range of moderate-draw applications. Its combination of light weight, fully sealed construction, and an intelligent built-in BMS makes it the reliable upgrade choice for operators who are tired of maintaining, watering, and replacing lead-acid units every 1–2 years.
1. Golf Carts & 24V Electric Vehicles For golf carts, resort utility vehicles, and campus EVs running on a native 24V architecture, the Amptron 24V 50Ah is a straightforward drop-in lithium upgrade.
-
Significant Weight Reduction: At 13.5kg, this battery is less than half the weight of an equivalent 24V AGM unit (typically 28–35kg). On a golf cart, that weight saving translates directly into reduced tyre wear, better handling on slopes, and improved range per charge.
-
Longer Range Per Charge: 100% usable capacity versus approximately 50% for AGM means you're effectively getting twice the usable energy from the same rated Ah — covering longer courses or more holes between charges without the voltage sag that AGM suffers in the final third of discharge.
-
140A Peak for Hill Starts: The 140A (5s) peak discharge handles the high current demand of climbing steep cart paths and starting on inclines with a loaded cart — situations where undersized batteries sag, stall, or trigger BMS cutout on lesser products.
-
Zero Maintenance: No electrolyte to top up, no terminals to clean, no acid to neutralise. For fleet operators managing multiple carts, this eliminates the routine battery maintenance labour that adds up significantly over a season.
2. Mobility Scooters & Powered Wheelchairs For 24V powered mobility devices where battery weight, size, and reliability are critical factors for the user's daily independence.
-
Like-for-Like Physical Replacement: The 330 × 172 × 215mm footprint matches common 24V deep-cycle battery tray dimensions in popular mobility scooter and power wheelchair platforms. Verify your tray dimensions before ordering.
-
Lighter Device, Greater Comfort: Reducing battery weight by 15–20kg on a mobility device makes a measurable difference to the device's handling, portability, and the physical effort required to load it into a vehicle or lift it for travel.
-
Consistent Power to the Last Percent: LiFePO4's flat discharge curve maintains motor controller voltage within operating range right through to 10% SOC — unlike AGM batteries that cause progressive loss of speed and hill-climbing ability as they discharge.
-
Versatile Mounting Orientation: The Amptron 24V 50Ah can be mounted upright or on its side, giving mobility device engineers flexibility in retrofitting existing tray configurations that were designed around cylindrical or differently oriented lead-acid cells.
3. 24V Marine Trolling Motors & Auxiliary Systems For anglers and boaters running 24V trolling motors on smaller vessels — tinnies, aluminium fishing boats, and kayak-style platforms — where every kilogram of battery weight matters.
-
Replaces Bulky Two-Battery Series Banks: One 24V 50Ah replaces two 12V batteries wired in series, eliminating the imbalance risk that develops between two separate lead-acid batteries over time — and freeing up the space and weight of an entire second battery.
-
IP65 for Wet Environments: Fully sealed against dust ingress and low-pressure water jets, making it suitable for open-cockpit boat environments where spray and splash are routine.
-
All-Day Light-Motor Runtime: At 1,280Wh, the 24V 50Ah comfortably powers a 24V trolling motor (Minn Kota, MotorGuide) at medium thrust settings through a full day's freshwater or inshore saltwater fishing session.
-
Fast Recharge Between Sessions: Accepts up to 50A charge current, so a quality 24V LiFePO4 charger can restore the battery to full from flat in as little as 1–1.5 hours — ready for the next morning's early start.
4. Compact Off-Grid & Caravan Solar Storage For lightweight camper trailers, pop-top caravans, and compact off-grid setups running a 24V solar architecture where space and weight are at a premium.
-
Half the Weight of Equivalent AGM: 13.5kg versus 28–35kg for a 24V 50Ah AGM unit — a critical advantage in weight-sensitive caravan and camper trailer builds where payload margins are tight.
-
2,000+ Cycles at Full Discharge: Daily cycling at 100% DoD delivers over 5 years of service life — significantly outlasting AGM alternatives that degrade rapidly with deep discharge cycles and typically need replacement every 18–24 months.
-
Solar Compatibility: Compatible with 24V MPPT solar controllers configured for LiFePO4 chemistry (charge voltage 29.2V). Accepts solar charge current up to 50A maximum for rapid topping from a modest panel array.
-
Versatile Mounting: Can be installed upright or on its side to suit shallow under-bunk or under-floor battery compartments in compact vans and trailers.
5. Security, Surveillance & Remote Monitoring Systems For 24V uninterruptible power supply (UPS) applications, CCTV systems, access control panels, and remote monitoring equipment requiring reliable standby power.
-
Stable Float Voltage: LiFePO4 chemistry maintains a stable resting voltage, making it compatible with 24V DC security and monitoring infrastructure that requires consistent bus voltage to operate correctly.
-
Long Standby Life: With up to 12 months of storage at ≥80% capacity retention, this battery is well-suited to infrequently cycled standby applications where consistent readiness is the primary requirement.
-
IP65 Enclosure for Outdoor Cabinets: Suitable for deployment in IP65-rated outdoor equipment enclosures, remote repeater housings, and weatherproof security panel boxes without requiring additional battery enclosure protection.
-
BMS Safety for Unattended Installations: The automatic BMS protection features — low voltage cutout, over-current protection, thermal cutout, and short-circuit protection — provide a layer of safety critical for unattended installations where manual monitoring isn't possible.
