48V 100Ah LiFePO4 Battery Golf Cart Lithium Battery Conversion Kit ABS Case

Product Overview

The 48V lithium golf cart battery in this kit is a single 100Ah LiFePO4 pack built to sit where a lead-acid bank used to live. Matched class A cells sit inside a sealed ABS case, and the outside carries nothing more than a positive terminal, a negative terminal and two side handles. Owners arrive at this pack from two directions. Some run a cart every day — a course loop, a residential estate, a farm track — and the old set no longer makes a full round. Others are rebuilding a used cart and would rather fit lithium once than replace a set of lead-acid batteries every few seasons. Both want the same answer: can one case do the work of six or eight? On a standard 48V cart it can. Day-to-day life with it is quiet. The discharge curve stays flat, so the cart still pulls when the gauge sits in its last quarter instead of fading over the back nine. Plugging in after nine holes does no harm either — the 100Ah LiFePO4 battery takes a partial charge and carries on, which is more than a flooded set manages.

What the Kit Includes

• One box, not four orders — the lithium golf cart batteries 48V conversion kit, its 18A charger, the LCD monitor and the mounting screws all travel together.
• Battery pack — the lithium battery for golf cart use at the centre of the kit: 100Ah LiFePO4 in a sealed ABS case, with side carry handles and M8 terminals on top.
• 48V 18A charger — matched to this pack rather than a generic 48V unit, with a cooling fan and a carry handle of its own.
• LCD monitor — a dash panel with its own bracket and lead, so the readings are on the cart even when your phone is not.
• Phone app — pairs with the pack over Bluetooth and puts the same live data on a screen you already carry.
• What you reuse — the cart's main positive and negative cables and its existing hold-down. If the lugs are green with corrosion, replace them while the tray is open rather than after the pack is bolted down.

Power Delivery and BMS Protection

Cart motors ask for two very different things: a steady draw on the flat and a short, heavy surge when you pull away with passengers or climb a ramp. The pack is rated for both, with a continuous figure that covers a standard 48V motor and a peak that holds up long enough for a hill start.

The protection board inside these lithium ion golf cart batteries is what makes that rating usable. It keeps the pack inside its limits while the cart is moving, so the controller sees a steady voltage instead of a number that sags every time the motor loads up. Less sag means the cart feels much the same on the last hole as it did on the first.

Peak figures are, by design, short. They exist for acceleration and for the moment a loaded cart starts on an incline; a sustained draw above the continuous rating is a different job and will trip the pack rather than quietly cook it. That distinction matters if you plan to run something heavier than a cart motor — a large trolling motor, a hydraulic attachment, a trailer on soft ground — so compare that equipment's continuous draw with the ratings in the specification table before you order.

Temperature is part of the same protection: the pack declines work outside its windows rather than taking damage quietly. On a hot afternoon or a freezing morning, that is the behaviour you want from equipment standing in a shed.

ABS Case, Weight and Compartment Fit

• One-person lift — side handles and a case that takes up roughly a third of the space the lead-acid set needed, so the swap is a two-hand job rather than a two-person one.
• Sealed ABS housing — no acid, no corrosion crust on the terminals, and a shell that will not rust when the cart lives outdoors.
• Non-conductive case — the housing insulates the cells from the cart frame, which is one less path for a stray current to take.
• Top terminals with clear access — standard cart lugs bolt straight on; check your lug size against the terminal before you start rather than mid-job.
• Measure the tray, not the old battery — a lithium battery for golf cart use only helps if the case fits, so take length, width and height including any hold-down bar, and leave room for the cables to bend without strain.
• Leave a route for the monitor lead — a few centimetres of clearance at the front of the tray saves drilling later.
• If the tray is tight — send us the measurements and a photo before ordering; a re-drilled hold-down or a small spacer often settles it.
• Rough sites — these lithium ion golf cart batteries are built for normal cart duty; if your cart works where the pack takes knocks, ask us about the metal-case version of the same capacity.

Installation and First Charge

1. Park on level ground, switch the cart to tow or maintenance mode, and disconnect the main negative lead from the old bank first.
2. Photograph the wiring before anything comes apart — the cart's main positive and negative leads are the two you keep.
3. Lift out the lead-acid batteries and the interlinking cables.
4. Clean acid residue out of the tray and let it dry, then lower the golf cart lithium battery in with the terminals facing the existing cables.
5. Bolt the main leads to the terminals with the supplied fixings, negative last, and check each one is snug rather than over-tightened.
6. Fit the LCD monitor to the dash, route its lead clear of the steering and any moving parts, and clip the panel into its bracket.
7. Charge to full with the 18A charger before the first run, then pair the app and check that its readings match the LCD.

Charging with the Included 18A Charger

The 18A charger in the box is sized for this pack rather than borrowed from a lead-acid cart. At that current a pack emptied by a long day refills in a few hours, so a morning round can be followed by an afternoon one without the cart sitting out overnight.

The routine is simple. Set the charger on a dry surface with air moving around it — the fan needs somewhere to push heat — connect the lead to the pack and leave it. The charger tops out at the pack's charge voltage, and if anything pushes past that the protection board cuts in behind it, so overcharge is guarded twice rather than once.

Cold mornings need a little patience. Charging is specified for ambient temperatures above freezing, and the one thing to avoid is plugging in a pack that is still cold from an unheated shed. Let it come up to working temperature first; the discharge window is far wider, so a cold cart will still run even when it will not yet charge.

For the off season, park the cart with the pack somewhere around half charge rather than empty and top it up every few months. Leaving this class of 48V golf cart batteries flat for a winter is the mistake that costs capacity; a maintained pack comes back in spring with its range intact. Keep the charger itself indoors and dry — the cart can live outside, the charger should not.

One habit worth building: charge after use rather than before. A 100Ah LiFePO4 battery that goes back on the charger warm and half full is ready whenever the cart is, and it never sits deeply discharged for days on end.

- Voltage has to match before anything else — this 48V lithium golf cart battery is charged at 58.4V. A 36V unit, a 12V car charger or a maintainer borrowed from the workshop will never bring the pack to full, and the protection board cannot correct a charger that is on the wrong voltage. - Why the old lead-acid charger has to stay on the shelf — a lead-acid charger runs a long absorb stage and then holds a float voltage for as long as it is plugged in. A 100Ah LiFePO4 battery wants a fixed current and voltage charge up to 58.4V and then to be left alone; holding a float on a full pack keeps working the cells for no extra range. - What the label should say — 48V (51.2V nominal) LiFePO4, charge voltage 58.4V, and a current the pack accepts. If the only marking is lead-acid, AGM or gel, it is the wrong tool for this chemistry. - The 18A charger in the box — a dedicated 48V LiFePO4 unit rather than a repurposed cart charger, with an IP65 housing for a damp shed or an outdoor charging point and a three-colour lamp that steps through the charge so you can see where it is without the app. - Charging at the course — many clubs still run a shared lead-acid fleet charger on the cart bay. Plug into your own unit instead and leave the club charger for the flooded carts it was bought for. - Already own a lithium charger? — check three things before using it: 58.4V charge voltage, a connector that matches the cart's charging lead, and a current rating no higher than the pack's maximum continuous charge figure in the specification table. - Power and placement — charge from a properly rated outlet, skip long thin extension leads, and keep the charger itself dry and indoors while the cart stays outside. A plug timer that cuts the supply part-way through is not dangerous, it simply leaves the pack part-charged for the next session.

Battery Monitoring: LCD and App

• Dash LCD — the panel measures 2.76 × 0.98 × 1.77 in and mounts on the cart's dash, showing state of charge, voltage, current and a status line.
• Home, Data and Fault pages — everyday readings sit on one screen and the fault log on another, so a warning is not buried in a scrolling number.
• Bluetooth range — pair once and the app reads a golf cart lithium battery from up to 20 m away, so a check from the clubhouse or the workshop does not mean lifting the seat.
• What is worth watching — state of charge before a round, voltage under load on a long climb, and the fault page after a hard day.
• Two displays, one pack — the LCD stays with the cart; the app suits the owner who wants to look at a deep cycle lithium battery's numbers over a week of rounds without walking out to the shed.
• Mounting — bolt the bracket to the dash and route the lead clear of the steering column, the pedal linkage and anything that moves.

Typical Applications

Golf carts come first, and that covers more ground than a course: club carts, estate and neighbourhood carts, and farm carts that spend the day carrying tools or feed. The 48V lithium golf cart battery is built around that duty cycle — short runs, frequent stops and a charge at the end of the day.

The same pack suits ride-on mowers and garden equipment running on 48V, where a lighter case is easier to lift on and off for seasonal storage.

Campers and RV owners use it as house power for lights, a fridge and a fan. The maintenance-free side matters more there than outright capacity, because nobody wants to check water levels at a campsite.

Marine use is possible, including trolling motors, with one caveat: a trolling motor can pull hard for long stretches, so compare its continuous draw with the pack's ratings before committing.

Home backup and small off-grid setups are the last fit, provided the inverter is a 48V unit. A pack this size runs a few essential circuits through the night rather than a whole house.

Fleet owners replacing the 48V golf cart batteries in more than one cart can standardise on this case, which keeps chargers, monitors and hold-downs interchangeable across the group.
