48V 100 Ah LiFePO4 Golf Cart Battery with Bluetooth Battery Monitor, Low Temperature Shut-Off Function, Robust Metal Housing, 5.12 KWH Battery for Golf Carts, Solarlarge, RV

Product Overview

You install one unit, connect the main cables and drive, instead of stringing six or eight batteries together and hoping every jumper stays tight. Voltage holds steadier as the pack drains, so a cart that used to feel flat at half charge keeps pulling to the end of the round. What you are buying is a deep cycle lithium battery, not a starter battery. It is built for slow, repeated discharge — hauling a cart around a course, running lights and a fridge in a camper, holding a solar bank steady overnight — rather than for cranking an engine. Most owners arrive here from lead-acid for one of two reasons: the watering and terminal cleaning, or the way a lead pack fades after two or three seasons. A lithium golf cart battery removes the first completely and softens the second, because there is no acid to top up, no sulphation and no memory effect. The metal case, the cold-weather protection and the display are the three details worth understanding before you commit.

Metal Housing & Cell Fixture

• Formed metal case, not a moulded shell — The 48V LiFePO4 battery sits in a sheet metal housing that is fireproof and collision resistant. It takes the knocks, stones and constant vibration of a working cart, and it keeps the cells square where a plastic case can crack or flex.
• Every cell clamped by metal fixtures — The cell stack is held by metal clips instead of tape, foam or adhesive. Clamped cells do not shift under load or work loose over a season of rough ground, and the assembly stays rigid when the cart is bounced over kerbs and trailer ramps.
• Cell expansion kept under control — A LiFePO4 cell swells slightly as it ages, and that swelling is what quietly steals working life from a pack. The fixture resists it, and the design is credited with up to 30% longer life when paired with A-grade cells.
• Pressure relief valve on the top panel — If pressure builds inside, the valve releases it rather than letting the case take the strain. It sits next to the round power switch, so both are reachable without dismantling the compartment.
• One-key power switch — The switch isolates the pack for storage, service or cable work, and stops the small standby draw while the cart sits idle for weeks at a time.
• Metal where it counts — Many lithium golf cart batteries rely on a plastic shell; this one is sheet metal end to end, with the terminals set into a recessed side panel where a dropped spanner is less likely to bridge them.

Low-Temperature Charging Protection

Cold is the one condition that quietly ruins a lithium golf cart battery, and it is the reason this pack carries a dedicated low-temperature shut-off. A temperature sensor reports to the battery management system, which allows charging only between 32°F and 131°F. Drop below 32°F and the charge circuit is cut; when the pack warms back to 32°F, charging resumes by itself, with nothing to reset and nothing to switch back on.

Discharge is allowed over a wider window — -4°F to 131°F — and output is only interrupted if the internal temperature falls below -7.6°F. A frosty morning start is therefore not a problem. Charging a frozen pack is, and that is exactly what the protection prevents.

Cold still costs capacity. Electric golf cart batteries of any chemistry deliver less in January than in July, and this pack is no exception: expect a shorter run in freezing weather and plan charging around it. Park the cart in a garage or somewhere that catches the sun, put it on charge straight after a run while the pack is still warm, and if it has spent the night outside below freezing, let the day warm up before you plug in.

Bluetooth & Touch Display Monitoring

• Touch display on the case — Voltage, current and state of charge are shown on the pack itself, so the cart can be checked without reaching for a phone. The screen draws its power from the battery's communication port, so there is no separate cell to go flat.
• The same readings on your phone — Bluetooth pairs the pack with the mobile app, so state of charge can be read while the cart is under a cover, in a shed or on a trailer. Useful the night before a round, and more useful still when a cart starts behaving oddly.
• A percentage instead of a voltmeter guess — Plenty of 48V golf cart batteries still leave you reading a voltmeter and doing mental arithmetic. Here the pack reports its own state of charge, so you know whether to charge tonight or whether the problem lies elsewhere.
• Current readings that diagnose a complaint — On a sealed 48V LiFePO4 battery, a sluggish climb can be a low pack or a tired motor. Watching current draw under load tells you which one you are dealing with before you spend money on the wrong part.
• Mounted where you can read it — The monitor, its cable and the mounting bolts for the display and the terminals come with the unit, so the screen can be fixed in a readable spot rather than left loose in the compartment.
• Handy when you look after more than one cart — Charge levels can be confirmed one cart after another from the app, without opening each seat or hunting for a voltmeter.

Installation & Fit Checks

1. Measure first. Confirm the cart is a 48V system and measure the old tray with the seat up — length, width, height, plus clearance above the terminals for the display cable. Most lithium golf cart batteries of this class fit, but tray shapes differ between Yamaha, EZGO and Club Car.
2. Check what you are removing. The pack should be six 8V or eight 6V blocks. That is the layout this battery replaces in one unit, which is why there is no rewiring to plan.
3. Make it safe. Switch the cart to tow or maintenance mode, then disconnect the main negative cable before anything else comes loose.
4. Clean the tray. Lift the old blocks out and deal with the residue — the acid that electric golf cart batteries leave behind will keep eating new terminals if it is left in place, so neutralise it and let the tray dry.
5. Set and secure. Lower the battery in, bolt it down and keep the pressure relief valve clear. Leave a little air around the case rather than packing foam against it.
6. Connect and check. Reconnect the main cables, positive first, and check polarity twice before the pack is switched on. Then plug in the display cable and mount the monitor where you can read it from the seat.
7. Charge before the first run. Switch the pack on and bring it to full charge, then confirm on the display that the pack is taking charge normally.

Ordering & Delivery

1. Check the fit before you buy. If this is your first time ordering a lithium battery for golf cart use, send over the cart model, the pack you are replacing and the tray measurements — settling the voltage and the compartment size first saves a wasted trip.
2. Lead time. In-stock orders are prepared in 3-7 days. Custom builds take 35 days.
3. Delivery. 48V golf cart batteries ship from local stock with swift delivery, and transit usually takes 3-7 days.
4. Warranty. Every unit is covered by a 5-year warranty.
