48V 100Ah LiFePO4 Golf Cart Lithium Battery 200A BMS Metal Case with 48V 18A Charger

Product Overview

This 48V lithium golf cart battery is a 51.2V, 100Ah LiFePO4 pack that replaces the six to eight 6V or 8V lead-acid blocks under the seat with a single unit. Range is where the swap earns its keep. The pack is rated for up to 56 miles of running, which works out at roughly 7 to 9 rounds of 18 holes before you need a socket again — enough for a weekend of play or a full day of shuttle work on one charge. Where a tired lead-acid set faded on the back nine, this one keeps pulling to the end of the round — the sort of range that leads owners to switch to lithium golf cart batteries.

Inside the case it is a 100Ah LiFePO4 battery holding 5120 Wh, so you keep the same nominal 48V as the pack it replaces while more of that capacity stays usable. Lead-acid cells dislike being run down and pay you back with a shorter life; this chemistry does not, and the 200A BMS watches current in both directions so a deep discharge stays inside safe limits.

It is covered by a 5-year warranty with US local warehouse support for fast after-sales service — backup worth having when you are comparing 48V golf cart batteries.

Metal Case and BMS Protection

Power Output and Cart Compatibility

As a golf cart lithium battery, the numbers that matter are the ones you feel from the driver's seat. The BMS is rated at 200A, the pack sustains 250A for 30 seconds, and it will take 700A for a second when you ask for it — the surge that gets four adults and a bag set moving up a ramp without the cart bogging down.

That headroom also changes how the cart behaves on a hill. Where a tired lead-acid set sagged and slowed on an incline, this deep cycle lithium battery keeps pulling, so climbing, towing and stop-start shuttle work all stay comfortably inside the continuous rating.

Fitment covers the common 48V carts — Yamaha, EZ GO and Club Car among them — and because six 8V blocks and eight 6V blocks both add up to the same 48V, most 48V golf cart batteries are sold as a single-pack swap like this one. Compartments are not identical, though: tray depth, terminal position and the height of the seat pan all vary, so take your measurements before ordering, and expect a little DIY adjustment on the tightest carts.

Installation and Lead-Acid Replacement

1. Measure the compartment. Open the battery bay and take the internal depth, width and height, then compare them with the dimensions in the specification table below. Cart makers changed tray layouts between model years, so the measurement matters more than the badge on the front.
2. Take out the old set. Six to eight blocks come out, along with the interconnect cables and the watering routine — the arrangement most lithium golf cart batteries are bought to replace, and the reason the bay looks so full.
3. Check the tray and the lugs. Wipe the tray dry, look over the mounting points and inspect the cable lugs for corrosion before anything goes back in.
4. Lower the pack in. A lithium battery for golf cart duty arrives at a fraction of the lead-acid weight, so one person can set it in place without a hoist. Line the terminals up with the existing cable runs and fix them with the supplied M8 terminal bolts.
5. Mount the monitor. Run the display cable to the top of the pack and fix the screen where it can be read from the driver's seat.
6. Switch on and charge. Press the power switch on the top panel, connect the supplied 18A charger, and let the 100Ah LiFePO4 battery take its first full charge before the cart goes back into service.

Charging and Automatic Cut-Off

• Charger in the box. The kit ships with a 48V 18A charger rated at 900W, matched to 48V golf cart batteries with LiFePO4 chemistry like this one rather than borrowed from the old lead-acid set.
• Plug and play. The charger goes straight onto the terminals with no adapters, no settings menu and nothing to configure before the first charge.
• Two layers of stop. The charger cuts out on its own when the 100Ah LiFePO4 battery is full, and BMS overcharge protection sits behind it as a second line of defence — which is the arrangement you want when the cart is left plugged in overnight.
• Top-ups are fine. A deep cycle lithium battery does not have to be run flat before recharging, so an hour on the charger between rounds is a sensible habit rather than a wasted one.
• Before long storage. If the cart will sit for weeks, charge it fully first and disconnect the terminals; a part-charged golf cart lithium battery left idle is harder on itself than a charged one.

Two-Way Battery Monitoring

• Bluetooth app. Pair your phone and read state of charge, voltage, current, battery temperature and fault status without lifting the seat.
• LCD monitor. The screen that comes with the kit shows the same figures on the cart itself — useful on lithium golf cart batteries where the pack sits out of sight — so anyone using it can see what is left at a glance.
• Both at once. The display runs several pages — home, notifications, system parameters, battery status — and the phone mirrors them, so checking capacity and voltage together on a deep cycle lithium battery is a glance rather than a calculation.
• Check before a round. A ten-second look before you set off tells you whether there is enough for 18 holes or whether a top-up first makes more sense; this lithium battery for golf cart duty shows the answer without guesswork.
• Faults surface early. Over-temperature, over-current and low-voltage conditions appear on the screen before they strand the cart, turning a roadside problem into a charge-and-carry-on decision.

Maintenance & Care

• Nothing to top up. The flooded blocks that came out of the cart needed water in every cell and a level check before each season. This lithium battery for golf cart use is a sealed LiFePO4 pack: no caps to open, no water to add, no acid to handle.
• No hydrometer, no equalising charge. Cell-by-cell readings and the occasional long equalise charge belonged to lead-acid ownership. Here the 200A BMS tracks the cells and reports capacity, voltage and any fault to the LCD screen on the cart or to the phone app.
• A monthly glance is enough. Park the cart, open the app or read the monitor and note the capacity figure. A slow drift downward over several weeks is worth a question to us; a normal drop after a long round is not.
• Keep the vent clear. The sheet-metal case has a vent on the top panel, and grass clippings, bag sand and workshop dust will find it. Brush it off whenever you clean the cart.
• Wipe, don't wash. A damp cloth over the case and around the terminals is all it needs. Keep the hose and the pressure washer away from the vent and the posts.
• Look over the fittings twice a year. The M8 terminals should stay dry and tight, so check the cable lugs for corrosion and re-tighten anything that has worked loose over a season of vibration. The tray fixings and the monitor cable deserve the same yearly look — maintenance-free covers the cells, not the installation.
• Switch it off when parked. The one-key safety switch on the top panel cuts standby draw, which is the right setting for a cart that sits for weeks between rounds.
• Retire the old charger. The supplied 48V 18A unit is built for this pack; a lead-acid charger runs a different charging profile and should not be used on it.

Shipping, Warranty and Support

1. Pick the warehouse. Orders ship from local stock in the USA or Europe; choose the closer one at checkout.
2. Dispatch. Standard orders are processed and dispatched within 3-7 days. Custom builds take about 35 days.
3. Delivery. Shipping takes 3-7 days from local stock — swift delivery rather than a long wait on a container.
4. Two parcels. Because of carrier weight limits, the battery and the 48V 18A charger travel in separate boxes. If only one arrives first, nothing is missing — the second is already on its way.
5. Warranty. The five-year warranty covers this 48V LiFePO4 battery and the charger supplied with it.
6. Fitting help. If the fit or the first charge is unclear, get in touch before you start rather than after; a quick question is easier than undoing a wrong connection.
