Everything needed for a typical swap is included, so you won’t be left hunting for a compatible charger or add-on accessories right away.

Key specifications at a glance

This section gives you the headline specs so you can quickly compare the battery to others and to your cart’s needs. Below is a concise table that breaks down the most important technical data and practical info.

Build quality and physical design

You’ll notice a robust, metal-cased design that aims for durability and safety in outdoor and semi-exposed conditions. The SPCC cold-rolled metal plate construction gives the battery a fireproof and shock-resistant shell, and the IP67 rating means it can resist dust and withstand immersion in water to a degree — important if you use your cart on dewy courses or around water.

Housing features and ruggedness

The metal housing is thicker and more durable than many plastic cases used on cheaper batteries, which helps protect cells from impact and vibration. You’ll find the terminals and connectors are recessed and often paired with robust mounting points so the battery stays secure during bumpy rides.

Size, weight and how that affects your cart

By cutting the weight to about half compared with a similar lead-acid bank, you’ll reduce strain on the motor and drivetrain, and you’ll likely notice smoother acceleration and less wear on suspension components. The reduced mass also improves handling and can provide modest increases in range, since less energy is wasted accelerating the additional weight.

Battery chemistry and why it matters

This battery uses LiFePO4 cells, which are known for higher thermal and chemical stability, a longer cycle life, and safer failure modes compared to lithium cobalt or lead-acid chemistries. You’ll get more predictable voltage under load and a slower capacity fade over time, which makes LiFePO4 a popular choice for repeated deep cycles like those in golf carts.

Cell grade and performance implications

The manufacturer states Automotive Grade A LiFePO4 cells, which suggests consistent cell quality and tighter tolerances for capacity and internal resistance. For you, that translates to a stable, reliable discharge profile, better performance under heavier loads, and a longer useful life.

Built-in 200A BMS and safety protections

A 200A Battery Management System is integrated into the battery to protect against over-charge, over-discharge, excessive current, short-circuits, and high or low temperature conditions. You’ll appreciate the BMS because it actively prevents many common failure modes and can extend the battery’s usable life while protecting your cart’s electronics.

How thermal and electrical protections work

The BMS monitors cell voltages and temperatures, isolating the battery if any parameter goes out of safe ranges and preventing catastrophic failure. You’ll also benefit from cell balancing to keep all cells at similar states of charge, which reduces stress and prolongs longevity.

Why the 200A rating matters for real-world use

200A continuous discharge supports most stock golf cart motors comfortably, and the 300A peak for short bursts covers sudden acceleration demands. If you like a brisk initial acceleration or run accessories, the higher current capability helps you maintain voltage under load without triggering protective cutouts.

Performance and power delivery in everyday use

You’ll get a steady voltage delivery through the discharge curve, which keeps speed consistent as the battery drains compared to lead-acid alternatives that sag more markedly. The 5.12 kWh capacity gives you a usable bank that, depending on how you drive and the motor’s efficiency, can handle typical course rounds or utility use with fewer charge cycles.

Continuous vs peak output and what they mean

Continuous 200A lets you sustain moderate loads—useful for prolonged hill climbs or towing small loads—while a 300A peak supports brief bursts like accelerating out of sand traps or starting on inclines. You’ll want to size your cart’s motor and controller to match these outputs for the best synergy.

Handling accessories and parasitic loads

If you run GPS, lights, stereos, or other accessories, this battery has the reserve capacity to handle those draws without significant drops in performance. You’ll still want to take note of total accessory load—especially if you’re aiming for maximum range.

Charging: included 56.8V 18A charger and charging behavior

The included 56.8V 18A charger is tailored to LiFePO4 charging profiles and supports relatively fast top-ups compared with smaller lead-acid chargers. You’ll be able to restore significant capacity overnight or faster depending on how depleted the battery is and whether you use any supplemental charging strategies.

Typical charging times you can expect

Charging from 0% to 100% at 18A on a 5.12kWh battery theoretically takes roughly 5–6 hours accounting for efficiency and tapering, but in practical scenarios you’ll usually charge from partial states and finish faster. You’ll also get quicker top-offs after short rounds rather than full cycles if you plug in between uses.

Charger behavior and BMS interaction

The charger negotiates with the battery through the BMS to ensure the correct charge voltage and current, and the BMS will terminate or taper charging when the battery hits safe thresholds. You’ll see the onboard display and app show charging progress and state-of-charge so you’re not guessing.

Bluetooth, app monitoring and onboard display

The built-in Bluetooth and dedicated app let you view real-time statistics such as state-of-charge, voltage, current, cell voltages, and sometimes temperature depending on the app’s features. You’ll appreciate this level of visibility because it removes uncertainty about remaining range and allows you to spot issues early.

What you can monitor with the app

At a minimum you’ll monitor SOC, charging status, and error codes; more advanced apps also show cell balancing activity, voltage per cell, and historical logs. You’ll be able to check the battery from your garage without walking to the cart, which is convenient and reassuring.

Using Bluetooth on the course and practical tips

On the course, you’ll mainly use the app before and after rounds to confirm charge and health; during use, the onboard display provides immediate readouts. You’ll want to pair the app and keep it updated, and make sure Bluetooth is enabled before heading out to avoid missing real-time notifications.

Installation and compatibility with your cart

This battery is built to be compatible with the major golf cart controllers on the market, so you’ll often be able to swap it in without controller modifications. You’ll still check terminal spacing, mounting footprint, and voltage compatibility to ensure a straightforward installation.

Using the external switch and dashboard mounting

An included external switch and cable let you install an on-dash cut-off switch so you can power down the battery without accessing the battery box. You’ll find this practical for daily use and safety; the green indicator on the main battery switch makes on/off status obvious at a glance.

Fitment tips and pre-install checklist

Before swapping, measure battery bay dimensions, confirm terminal polarity and cable lengths, and check chassis mounting points. You’ll also inspect the cart’s controller and wiring for corrosion or damage and ensure the charger plug is accessible and compatible.

Range and runtime expectations in real life

Range will vary with terrain, load, speed, motor efficiency, and accessory usage, but the manufacturer suggests up to around 50 miles in very efficient conditions. For most golfers with normal driving and reasonable loads, you should expect significantly more usable range than an equivalent lead-acid set, and the usable percentage of capacity will remain higher in everyday use.

Calculating realistic range for your use case

To estimate, calculate your cart’s average kW usage per mile (or amp draw per hour) under typical conditions and divide the 5.12 kWh capacity by that number after accounting for inverter inefficiencies and BMS buffers. You’ll want to conservatively assume 75–90% usable capacity in practice, depending on ambient temperature and load, to avoid cutting it too close.

How weight reduction extends range

With roughly 50% less weight versus lead-acid, you’ll use less energy accelerating and climbing, so average amp draw declines and range increases. You’ll likely notice better top-end speed retention uphill and a steadier feeling at mid-throttle.

Safety features and certifications

The battery includes multiple safety features built into the BMS and casing — over-current protection, over-voltage and under-voltage cutoffs, high/low temperature protection, and short-circuit protection. You’ll also benefit from a fire-resistant casing and IP67 waterproofing for peace of mind when using the cart in damp or wet conditions.

IP67 waterproofing and outdoor use

IP67 means the battery is dust-tight and can withstand immersion up to a specified depth for a limited time, which is more than adequate for puddles, heavy dew, and typical course conditions. You’ll still avoid prolonged submersion, but everyday outdoor exposure should be well handled.

Fireproof and shockproof case considerations

The SPCC metal case and reinforced internal mounting reduce chances of mechanical damage and contain faults more safely than thin plastic enclosures. You’ll feel safer knowing the design minimizes the chance of cell damage from impact or vibration.

Maintenance, lifespan and expected cycles

LiFePO4 chemistry typically gives you thousands of cycles before significant capacity loss; many LiFePO4 batteries are rated for 2000–4000 cycles depending on depth of discharge and operating conditions. You’ll benefit from a much longer useful life than lead-acid batteries, which reduces replacement frequency and lifetime cost.

Cycle life, degradation and warranty realities

If you cycle the battery moderately (e.g., partial cycles and not always full-depth discharges), you’ll likely get the upper end of cycle life estimates. Check the manufacturer’s warranty terms to confirm coverage period and conditions, and keep documentation for any future claims.

Minimal daily maintenance required

You won’t need to add water, balance cells manually, or perform corrosive maintenance steps common with flooded lead-acid systems. You’ll still conduct occasional visual inspections and keep terminals clean, but daily chores are essentially eliminated.

Comparison with lead-acid batteries

Switching from lead-acid to this LiFePO4 unit will give you a lighter battery, faster recharge, longer cycle life, and better voltage stability under load. You’ll pay more upfront than a single lead-acid battery but recoup much of that cost through longer life, reduced maintenance, and improved performance.

Upfront cost vs lifetime value

While the initial investment is higher, you’ll likely break even after a few years when you account for fewer replacements, no watering, less charger time, and better efficiency. You’ll also save on labor and downtime if you run a fleet.

Weight, performance and environmental advantages

You’ll enjoy improved handling, less stress on your drivetrain, and better energy efficiency due to reduced weight. LiFePO4 chemistry also tends to be more environmentally friendly over its lifecycle compared with some lead-acid variants, especially flooded cells.

How this compares with other LiFePO4 options

Against other LiFePO4 offerings, the TEMGO 51.2V 100Ah stands out for including a high-current 200A BMS, a fast 18A charger, Bluetooth/app integration, and a rugged metal case. You’ll find cheaper LiFePO4 batteries that cut corners in case quality, BMS robustness, or monitoring features, so this model aims to balance features and durability.

What sets the TEMGO model apart

The combination of automotive-grade cells, a high continuous discharge rating, included charger, and app monitoring gives you a comprehensive package that’s ready to install. You’ll save time and avoid compatibility headaches that can arise when buying separate chargers or monitors.
