Product Overview
A 48V lithium golf cart battery solves the weight, the watering and the slow decline of a lead-acid set. The four parts are matched to one another as a lithium golf cart batteries 48v conversion kit, so the panel feeds the controller, the controller feeds the battery, and the charger stands by for the days when the sun does not keep up. Carts from Yamaha, Club Car and EZ GO are the usual homes for it, and it is built around 48V carts that carry a bank of 8V lead-acid blocks under the seat. Course maintenance teams get the most from it, because the panel keeps working between rounds instead of waiting for a plug. Estate and yard carts, hunting camps and rural properties gain in the same way: park in the open and the pack is fuller when you come back. Nothing about the way the cart drives changes. It still charges from the wall when you want a guaranteed full pack; the solar side simply reduces how often you need to. Across a sunny week the panel can cover a real share of the daily draw, and across a cloudy one it covers less, with the charger making the routine reliable in either case.
What's in the Box
- 130W solar panel — a thin panel with four mounting holes and roughly 70% less weight than a rigid panel of the same rating.
- 51.2V 100Ah LiFePO4 battery (5120Wh) — the golf cart lithium battery at the centre of the kit, with top terminals, a handle at each end and a 200A smart BMS built in.
- 300W MPPT charge controller — aluminium housing with cooling fins and a data display on the front panel.
- 48V 18A charger — a fan-cooled golf cart battery charger with its own carry handle, so it can move between carts.
- Battery monitor — a compact LCD screen that shows pack status without opening the phone app.
- Wiring diagram — the two-connection layout is printed and packed with the system.
- Connection cables — for the panel-to-controller and controller-to-battery runs.
- One matched lithium golf cart batteries 48v conversion kit — the panel, controller and battery are specified as a set rather than picked separately, which is where most mismatches happen.
Panel and Daily Yield
The panel is the part that changes the daily routine. It is a 130W flexible unit that mounts flat on the cart roof as a canopy, and because it bends it will follow a slightly curved roof rather than sit up on standoffs. Four holes take the fixings, and it adds very little to the roof load, which matters on a cart that already carries a canopy and a rear seat. For a deep cycle lithium battery in a golf cart, that roof space is the one place solar can work without a separate ground mount.
On a good day the numbers are easy to follow. Four hours of usable sunshine gives around 520Wh, which against the full pack is a little over a tenth of a charge a day — often the difference between finishing the round on the same pack and reaching for the charger. Winter, shade from trees, a cart parked under cover or a roof angled away from the sun will all pull that figure down, so treat the panel as a top-up source rather than a substitute for a full mains charge.
Because the panel is matched to the 48V LiFePO4 battery in the kit, there is no separate regulator to add and no second set of settings to learn. The controller applies the right charge profile, and charging continues while the cart is in use, so the roof keeps working on the fairway as well as in the shed.

Charging, Control and Monitoring
- MPPT tracking with headroom — the 300W controller is rated well above the 130W panel, converting at 95% or better with peaks near 99%, so the panel's output is not lost to heat or passing shade.
- 13-65V input window — the controller accepts a range that covers 36V, 48V and 60V systems, which leaves room to move the unit to another cart later.
- Aluminium case, -4 °F to 122 °F — a metal body and cooling fins keep it stable through cold mornings and hot afternoons.
- Display on the controller — voltage, current, single-cell voltage and cell temperature are all readable without a phone.
- Bluetooth app plus LCD monitor — capacity, power draw and pack detail in two places. The Bluetooth link takes one device at a time, so switch between the app and the screen rather than expecting both at once.
- 48V 18A charger for full top-ups — the included golf cart battery charger plugs in like any other and brings the pack back to full when solar alone will not do it.
- Generator-friendly — if the cart lives away from mains power, the same charger can run from a generator, so the LiFePO4 solar battery always has a fallback.
- Profile already matched to the 48V 100Ah LiFePO4 battery — there is nothing to configure on the controller before the first run.
Wiring and First Start
- Confirm the cart. Look for a 48V badge, then measure the battery bay and note where the terminals sit. The mounting points will not line up with your old blocks, so plan new tie-downs before anything comes out.
- Mount the panel. Fix it through the four holes in the panel, then run the cable down to where the controller will sit.
- Connect the battery to the controller. This is the first of the two connections the kit is built around. The 100Ah LiFePO4 battery has handles at each end, so lift it in with two people and set it on a flat, secure base.
- Connect the panel to the controller. This is the only link between the panel and the LiFePO4 solar battery, so check the plug is fully seated before you power anything up.
- Switch on and read the display. With the roof in the light, voltage and current should both be moving. If current stays at zero, the panel cable is the first thing to check.
- Pair the app or fit the monitor. Check the state of charge before the first long run, then give the deep cycle lithium battery a full charge before you rely on it for a whole day.
- Top up with the charger if the pack has been sitting. The golf cart battery charger is the quickest route to a known-full pack, and it is also how you confirm the system is behaving normally.

FAQ
Will this 48V lithium golf cart battery system fit my cart?
It is built for 48V carts that run six 8V lead-acid blocks, which covers the common Yamaha, Club Car and EZ GO layouts. Two things decide fit: the voltage of your cart and the size of the battery bay. Measure the bay and note where the terminals sit before ordering. If the compartment is unusually shallow or split into two, send us the measurements and we will tell you what has to change.
Do I still need the wall charger once the panel is fitted?
Yes, and it comes with the lithium golf cart batteries 48v conversion kit. The panel is a top-up source: on four hours of good sun it puts back around 520Wh, a little over a tenth of the pack. The charger is what gives you a guaranteed full pack before a long day or after a cloudy week. Treat solar as the everyday trickle and the charger as the reset.
Does the panel charge while the cart is being driven?
Yes. The panel is wired through the controller to the pack, so it charges whenever the roof is in the light, parked or moving. Output while driving is lower than a stationary panel angled at the sun, but a golf cart lithium battery on a course spends hours in the open, and those hours add up. Full top-ups are still the charger's job.
How long will the battery last, and how deeply can I discharge it?
The pack is rated for up to 4000 deep cycles, which is roughly a decade of regular use. It is a deep cycle lithium battery, so it is built to be run down rather than kept permanently topped up, and 100% depth of discharge is within its normal range. Charge when it is low rather than after every short trip.
Is it a 48V battery or a 51.2V battery?
Both figures describe the same pack. Nominal voltage is 51.2V, and it is sold as a 48V LiFePO4 battery because that is the cart platform it serves. The charge profile is already set in the controller and in the charger, so nothing on the cart needs reconfiguring.
Can I keep using my old golf cart battery charger?
Only if it is a 48V lithium charger with a LiFePO4 profile. A lead-acid charger will not bring this pack to full and should not be connected to it. The unit supplied with the kit is already matched to the battery, so the simplest approach is to keep the two together. If you want to run a different charger, send us its output voltage and charge profile first.
Is the battery strong enough for a lifted cart with larger tyres?
The pack's BMS has the headroom for the higher currents a lifted cart pulls on hills and grass. Capacity stays at 100Ah / 5120Wh either way; what changes with bigger tyres and extra weight is how far that capacity takes you, so plan on the shorter end of the range estimate. Check that a lifted cart still leaves room for the pack and its tie-downs.
Can I add a second solar panel later?
The controller is rated to 300W and accepts 13-65V, so there is headroom above the single 130W panel in this kit. Before adding anything, send us the new panel's wattage, open-circuit voltage and current so we can confirm it stays inside the controller's window. Do not connect an unverified panel to a LiFePO4 solar battery system without checking those input limits first.
