Technical specifications (at a glance)

Below is a quick reference table that summarizes the main specs so you can compare them with other options quickly and clearly.

How to use this table

You can use this quick spec table as a checklist when comparing other batteries or when verifying compatibility with your vehicle’s space, weight limits, and electrical system.

Design and build quality

The design intentionally mimics a lead-acid case so you can drop it into a standard battery compartment without fabrication. The physical build prioritizes safety and stability while also trimming weight to a manageable 77 lbs, which is significantly lighter than typical lead-acid equivalents.

Lead-acid tray compatibility explained

Because it uses a lead-acid case form factor, you avoid issues with fitment and mounting; the battery sits in the same footprint as your previous batteries. That design choice reduces installation complexity and ensures you don’t need custom trays or brackets.

Dimensions, weight, and space savings

At 20.55″ x 10.55″ x 8.74″, the unit is compact and should fit into many standard 48V golf cart battery compartments. Weighing 77 lbs, it saves you a lot of weight compared to flooded lead-acid banks that would otherwise be used to deliver similar usable capacity.

Why size and weight matter for you

Less weight translates into better handling for your cart, improved efficiency, and reduced strain on suspension components. The compact dimensions also free up potential storage or conversion space if you have tight battery bays.

Battery Management System (BMS)

The 200A smart BMS is a critical component that protects cells and extends battery life. It offers over-current, over-voltage, under-voltage, short-circuit, and over-temperature protection, plus cell balancing to maximize cycle life and prevent premature degradation.

What the smart BMS does for your battery

The smart BMS actively manages cell voltage and temperature and prevents unsafe conditions, so you can push the battery hard without losing reliability. It also communicates with the LCD and mobile app so you can see real-time status and receive alerts.

Performance and power delivery

With 10.24kW peak power and a 200A BMS, you’ll notice responsive acceleration and strong hill-climbing ability compared to most lead-acid systems. Continuous power delivery is smooth, and the battery is less voltage-sag prone, which means better performance late in the discharge cycle.

Real-world implications of peak power

That peak power rating translates into the ability to handle sudden loads—like steep inclines or heavy payloads—without the sluggishness common to older batteries. You should see more consistent speed and torque, especially on demanding terrain.

Cycle life and longevity

The battery advertises 4000+ cycles, which for LiFePO4 chemistry is a realistic and valuable advantage over lead-acid options that typically give 300–1000 cycles depending on depth of discharge. That longevity reduces your total cost of ownership because you’ll replace batteries far less frequently.

How cycle life affects your ownership costs

If you run daily use and keep depth of discharge moderate (e.g., 50–80%), you’ll likely get many years of reliable service before capacity fades meaningfully. Fewer replacements mean lower maintenance costs and less environmental waste.

Charging: included charger and charging behavior

You get a 48V 20A charger included with the kit, which offers a practical charge rate for overnight or multi-hour top-ups. The charger is designed specifically for lithium chemistry, which prevents harmful charge profiles that can shorten LiFePO4 life.

Charging tips and expectations

For longest life, you should avoid extreme temperatures and try to keep charging between 20% and 90% SOC for frequent use, while using full charges when you need maximum range. The included charger is adequate for typical daily cycles and supports safer recharge compared to generic chargers.

Monitoring: LCD touch screen and app connectivity

You can monitor battery status directly on the integrated LCD touch screen and remotely via a smartphone app. That dual approach gives you both immediate local access and convenient remote oversight to check SOC, voltage, temperature, and other parameters.

Why monitoring improves your experience

Real-time feedback helps you avoid unexpected cutoffs by showing you state of charge and any warning conditions before they become serious. App compatibility also simplifies fleet management if you operate multiple carts and need remote status checks.

Safety features in depth

Safety is prioritized with LiFePO4 chemistry and the smart BMS protecting against over-charge, over-discharge, over-current, short-circuit, and over-temperature. The robust containment in a lead-acid style case also helps prevent physical damage to cells from external forces.

Practical safety considerations for you

You should still follow basic battery safety: avoid physical puncture, use recommended cables and fuses, and don’t expose the battery to extreme heat or flames. Regularly review diagnostics via the app and LCD to catch anomalies early.

Installation and setup

The SISWAY battery is designed to be plug-and-play and to fit existing 48V trays, minimizing the chances of installation errors. The manufacturer provides video guides and written instructions, which you should follow carefully if you’re doing the swap yourself.

What to check before you install

Before installation, verify terminal orientation, secure grounding, correct fuse sizing, and that your controller or golf cart electronics are compatible with LiFePO4 battery voltage profiles. If in doubt, consult a technician or SISWAY support.

Compatibility with vehicles and systems

This battery is engineered for universal integration with 48V systems, including golf carts, some RVs, boats, utility vehicles, and off-grid energy storage setups. You should confirm the battery’s physical fit and electrical compatibility with your existing wiring and controllers.

Compatibility caveats to be aware of

Some older controllers or charging systems designed specifically for lead-acid may need minor adjustments to function optimally with LiFePO4. If your system relies on battery chemistry-specific indicators (like charge controllers tuned to lead-acid), check with SISWAY or the device manufacturer.

Use cases where this battery shines

You’ll see the most benefit in applications that require frequent cycling, reliable power delivery for acceleration, and long-term cost savings—like daily golf cart fleets, rental fleets, or heavy-use recreational vehicles. It’s also attractive for off-grid systems where longevity and predictable performance matter.

Where it’s less appropriate

If you only run your cart very occasionally and cost is the primary constraint, a cheaper lead-acid option may suffice in the short term. Also, very small vehicles with severe space constraints might require custom solutions.

Real-world performance expectations

In practical terms you should experience better range per charge compared to equivalent lead-acid setups because LiFePO4 supports deeper usable capacity and higher discharge efficiency. You should also see more consistent speed as the battery discharges due to reduced voltage sag.

Range and runtime considerations

Actual range depends on payload, terrain, speed, and accessories, but expect more usable amp-hours from the 100Ah LiFePO4 than the same amp-hour rating in lead-acid chemistry. That means in many cases you’ll travel further on a single charge.

Heat and temperature behavior

LiFePO4 chemistry tolerates temperature swings better than many lithium chemistries but still performs best in moderate conditions. The BMS protects against over-temperature, but you should avoid charging or storing the battery at extreme temperatures to maximize lifespan.

Tips for temperature-sensitive operations

If your usage involves extremes—very cold or hot climates—consider indoor storage or thermal management strategies, and check the battery’s behavior in your climate before committing to large fleet retrofits.

Maintenance and care

Overall maintenance is minimal compared to lead-acid batteries—no watering, less corrosion, and fewer routine checks—though you should still clean terminals, check mounting security, and monitor via the app or LCD. Periodic full inspections and firmware updates (if available) will help maintain long-term reliability.

Best practices for storage and long-term care

If you store the battery for extended periods, keep it at a moderate state of charge (around 40–60%), in a cool, dry place, and top it up occasionally to prevent deep discharge. Always use the provided charger or a recommended LiFePO4 charger when recharging.
