Quick Verdict

You get a solid, safety-focused 48V LiFePO4 option with the DC HOUSE 48V 50Ah Mini Golf Cart Battery with 18A Battery Charger, Bluetooth Mobile APP & Touch LCD Monitor, Low Temp Cut-Off, 2C-100A BMS, Peak Current 200A for Ryobi Mowers, Golf Carts. It’s built for rugged use, gives you clear battery monitoring, and supports parallel expansion—just be mindful of the shipping arrangement (battery and charger ship separately) and the rule against series connections.

Product Overview

This battery is a 48V 50Ah LiFePO4 pack designed for golf carts, mowers, RVs, trolling motors, and similar 48V systems. DC HOUSE emphasizes safety and durability by using a metal sheet casing and heavy metal fixtures to secure the cells. You’ll also get a 48V 18A charger, Bluetooth mobile app control, a touch LCD monitor, and a robust BMS that supports up to 100A continuous discharge with a 200A peak for 10 seconds.

Key Specifications

Below is a compact breakdown of the most important specs so you can see what matters at a glance.

What’s in the Box

You’ll receive the battery itself and an 18A charger—but they will be shipped in two separate packages due to weight. If you only receive one package at first, wait for the other to arrive. The package should include:

• DC HOUSE 48V 50Ah LiFePO4 battery (metal-cased)
• Touch LCD monitor (attached to battery)
• Bluetooth-enabled BMS
• 48V 18A charger (separate package)
• User manual with safety, wiring, and after-sales contact info

If any part arrives damaged (especially the LCD), contact the seller for replacement. DC HOUSE has said they’ll upgrade packaging to reduce damage risk.

Design and Build Quality

You’ll notice the first difference from typical consumer 48V packs is the sheet metal casing. Where many batteries use ABS plastic, this unit uses metal for superior impact resistance, better heat dissipation, and improved fireproofing. Inside, the cells are secured by metal fixtures that weigh about 2.2 lbs (1 kg)—this is more robust than foam or plastic braces and helps keep the cells stable under vibration and motion.

Because the cells are physically constrained better, DC HOUSE claims this contributes to longer cycle life—about a 30% improvement when combined with A-grade cells. For rough terrain, repeated vibration, or frequent handling, the metal case and fixtures should give you peace of mind.

Performance and BMS

The BMS is a critical part of any lithium system, and here DC HOUSE has chosen a 2C-100A BMS with a 200A 10-second peak capability. Translated to power:

• Continuous: 100A × 48V ≈ 4,800W continuous output
• Peak: 200A × 48V ≈ 9,600W available for short bursts (10 seconds)

That means you can accelerate aggressively or climb hills without immediate BMS cut-off, as long as you stay within the peak/current limits. The BMS also takes care of over-voltage, under-voltage, short-circuit, and temperature protections.

Important things you should know about the temperature protections:

• Charging is disabled if the pack temperature drops below 20°F (-6.7°C).
• Discharging is disabled if the pack temperature is below 4°F (-15.6°C).
• Normal operation resumes once the pack warms to 32°F (0°C).

This prevents lithium iron phosphate chemistry from being damaged by charging in extreme cold and safeguards the pack during freezing conditions.

Charging and Charger Behavior

You’ll use the included 48V 18A charger to refill the pack. Charger and battery are both equipped with BMS-level protections, so charging should be safe and well-regulated. A few practical notes to manage expectations:

• Charge current: 18A at 48V means the charger provides about 864W of charging power.
• Time to full (from empty): 50Ah / 18A ≈ 2.8 hours (theoretical). In practice, expect 3–4 hours because of tapering near full state and BMS behavior.
• Full-charge indicator: DC HOUSE recommends that the charger’s steady green light indicates a true full charge—if it flashes, the charge is not complete.
• Cold weather: Charger will not charge the battery below 20°F. If you live in cold climates, warm the battery above 32°F before charging to avoid capacity loss or BMS cut-off.

Because the charger ships separately, plan on receiving two shipments. If you get just one at first, allow extra time for the second.

Monitoring and Controls

You can monitor and control the battery two ways: a Bluetooth mobile app and an onboard touch LCD monitor. Both give you access to real-time metrics like state of charge (SOC), voltage, current, and capacity. The LCD offers three interfaces:

• Real-Time Display: instantaneous voltage, current, and SOC so you know exactly what’s happening.
• Battery Switch Control: lets you control the battery state (on/off) through an interactive screen.
• Battery Voltage: simpler view focused on voltage readings across the pack.

The Bluetooth app gives you the convenience of remote monitoring—especially helpful if you’re testing different loads, tracking ride cycles, or maintaining multiple packs. If you manage more than one battery in parallel, the app can simplify balancing and status checks.

Compatibility and Use Cases

This battery is intended for a broad range of 48V systems. You can expect compatibility with:

• Golf carts (Yamaha, Club Car, EZ GO)
• Electric lawn mowers and Ryobi-compatible setups
• RV house systems and cabin backup
• Trolling motors and small marine craft
• Off-grid systems and portable power setups that accept 48V LiFePO4

The pack’s stackable design and terminal layout are meant for space efficiency and easier mounting in typical battery bays. Before you swap this into your vehicle, confirm that your controller and motor system accept 48V nominal inputs and that they won’t require series arrangements—this pack explicitly forbids series connections.

Capacity Expansion Rules

If you want longer runtime, DC HOUSE allows parallel connection for capacity expansion, but with limits and rules:

• Parallel up to 4 batteries maximum (48V, 50Ah × 4 = 200Ah).
• Do NOT connect batteries in series—series configuration is strictly prohibited because it can cause catastrophic failure.
• Parallel connection increases capacity (Ah) but maintains system voltage at 48V.
• When paralleling, ensure all packs are at similar SOC and in similar condition to avoid large balancing currents at connection.

If you parallel four packs, you’ll achieve up to ~9.6 kWh (48V × 200Ah = 9,600Wh), which is a big boost for long rides or heavy electric loads—just check that peak current demand of your system stays below the 200A limit.

Installation Tips

You’ll want to handle installation carefully to get the most from this battery:

1. Inspect both packages on arrival for physical damage—especially the LCD and charger.
2. Mount the battery on a flat, well-ventilated surface. The metal casing helps with heat dissipation but keep it clear of combustible materials.
3. Observe polarity: connect positive first, then negative when installing. Reverse polarity can damage electronics.
4. If paralleling, match SOC and voltage before connection. Use a proper busbar or heavy-gauge wiring and torque to manufacturer specs.
5. Keep wiring runs short and use appropriately sized cables—this battery can deliver high current and voltage drop will cost you power.
6. Secure the pack against movement. The internal metal fixtures bolster cell stability, but the pack still needs to be fastened in-situ.
7. Confirm controller settings. Some older motor controllers or chargers may need parameter adjustments for LiFePO4 profiles.

If you’re not comfortable with high-current wiring, hire a qualified technician. DC HOUSE provides after-sales guidance for connection and charging.

Safety Features and Maintenance

DC HOUSE has emphasized safety in several ways that will matter to you in regular use:

• Metal sheet casing: stronger than ABS plastic, improves impact resistance and fireproofing.
• Metal cell fixtures: stabilize cells and reduce internal mechanical stress.
• BMS protections: against over/under-voltage, overcurrent, short-circuit, and temp thresholds.
• Low temp cut-offs: protect cell chemistry from damage during extreme cold.
• Charger with BMS protections: reduces risk during charging.

For maintenance:

• Keep terminals clean and torque-checked.
• Charge above 32°F if possible and store at moderate temperatures to preserve life.
• Avoid deep discharges below the recommended depth of discharge; LiFePO4 tolerates deep cycles better than lead-acid but consistent deep cycling will still affect life.
• Follow manufacturer guidelines and reach out to DC HOUSE for service—they offer 3 years of reported service.

Real-World Runtime Expectations

You can estimate runtime using the usable energy figure (~2.4 kWh). Here are practical examples so you can map battery size to your needs:

• If your motor/controller draws 800W average (moderate use on a golf cart), runtime ≈ 2.4 kWh / 0.8 kW = 3 hours.
• If average draw is 1,200W (heavier loads), runtime ≈ 2.0 hours.
• If draw is 2,400W continuous (heavy acceleration or steep climbs), runtime ≈ 1 hour.

Remember these are simplified calculations that don’t account for inverter losses, controller inefficiency, or regenerative braking. Also note that repeated high-current draws near peak will stress the pack more and can reduce effective capacity and lifetime.

If you parallel two packs (100Ah), you’d double these runtimes. Four packs (200Ah) would roughly quadruple them.

Pros and Cons

Here’s a clear list to help you decide quickly.

Pros:

• Metal sheet casing and heavy fixtures increase safety and ruggedness.
• 2C-100A continuous BMS with 200A 10s peak handles tough loads.
• Bluetooth app + touch LCD gives flexible, instant monitoring.
• Fast charging option with 18A charger (3–4 hours typical to full).
• Parallel expansion up to 4 packs for greater capacity.
• Low-temp protections prevent cell damage.
• 3 years reported service and seller support.

Cons:

• Batteries and chargers ship separately—may arrive at different times.
• No series connection allowed, so you’re limited to 48V systems only.
• Temperatures below 20°F disable charging; you’ll need to manage cold-weather operation.
• At nearly 50Ah and metal-cased, the pack can be heavier than thin ABS alternatives; check fitment.
• LCD can be damaged in shipping; report any issues promptly.

Troubleshooting & Common Questions

Q: The charger is not arriving with the battery. Should I worry? A: No. The charger ships separately due to weight. Wait a few days and check tracking. If the charger doesn’t arrive within the expected timeframe, contact the seller.

Q: Can you connect two of these in series to make 96V? A: No. DC HOUSE strictly forbids series configuration for these batteries. Doing so risks catastrophic failure and will void support.

Q: How many can I parallel? A: Up to four packs in parallel is allowed, giving you up to 200Ah at 48V.

Q: What happens if you try to charge below 20°F? A: The BMS prevents charging to protect cell chemistry. Warm the battery to above 32°F before attempting to charge.

Q: The indicator on the charger is flashing—what does that mean? A: DC HOUSE recommends that a steady green light indicates a full charge. If it flashes, the charge cycle may be incomplete or the BMS is still balancing.

Q: What routine checks should you do? A: Periodically check terminal torque, cabling integrity, and LCD/app readouts. Keep the battery dry and clean. If you see irregular voltages, overheating, or swelling, stop use and contact support.

Practical Comparisons

If you’ve used lead-acid batteries or cheap ABS-cased lithium packs, you’ll notice the difference:

• Compared to lead-acid: LiFePO4 provides higher usable capacity, lighter weight for energy, near-flat discharge curve, and longer cycle life. You’ll get more usable miles and far less maintenance.
• Compared to ABS-cased lithium: The metal case and internal fixtures in this pack provide better shock resistance and safety under rugged conditions, which is important for off-road or utility use.

If your system routinely sees moderate-to-high continuous currents, this pack’s 100A continuous rating is a strong selling point.

Warranty and After-Sales Support

DC HOUSE advertises 3 years of reported service. If you need help with wiring, charging, or troubleshooting, you can contact support via the Amazon order channel or the after-sales address included in the manual. Keep proof of purchase and serial numbers handy when you contact them for quicker assistance.

Final Recommendation

If your goal is to upgrade a golf cart, lawn mower, or other 48V equipment with a safe, monitoring-friendly LiFePO4 pack, the DC HOUSE 48V 50Ah Mini Golf Cart Battery is a very reasonable choice. You’ll appreciate the metal casing, robust BMS, and the convenience of Bluetooth and a touch LCD monitor for real-time information.

Plan for separate shipments of battery and charger, keep the battery within safe temperature ranges for charging, and follow parallel-connection rules if you expand capacity. If you need more runtime, consider paralleling two or more packs (up to 4), but verify your vehicle’s peak current draw first so you don’t exceed the 200A peak allowance.

Overall, this battery balances safety, performance, and expandability—making it a good fit for recreational and utility electric vehicles where durability and monitoring matter.
