DONGJING 51V 100Ah (5.12kWh) LiFePO4 Lithium Solar Battery

Are you tired of facing sudden K-Electric load-shedding and constantly changing weak lead-acid or tubular batteries? The Dongjing 51V 100Ah Lithium Battery brings high efficiency, fast charging, and long-lasting energy storage directly to your home or office in Karachi. Delivering 5.12kWh of reliable total energy, this wall-mounted Lithium Iron Phosphate (LiFePO4) unit gives you continuous power during long power outages.

Traditional lead-acid and heavy tubular batteries degrade rapidly due to Karachi’s hot weather, humid coastal climate, and back-to-back load-shedding schedules. They take many hours to recharge and require constant water refills. The Dongjing 51V 100Ah lithium battery eliminates all these problems by offering zero maintenance, intelligent protection, and rapid charging between power shifts.

Why the Dongjing 51V 100Ah Battery is Built for Karachi Homes

Karachi presents a unique set of challenges when it comes to power backup. Between high summer temperatures and unpredictable grid load-shedding, you need an energy storage system that charges quickly and performs smoothly without overheating. Here is why the Dongjing 51V 100Ah lithium battery is the ultimate upgrade for your solar system:

1. Long Lifespan with Safe LiFePO4 Chemistry

The Dongjing battery uses premium grade Lithium Iron Phosphate cells. Standard lead-acid batteries last only 1 to 3 years before losing backup capacity, but Dongjing delivers over 5,000 deep discharge cycles. This means you get a dependable operating life of 10 to 12 years under daily heavy usage in Karachi.

2. Rapid Recharging Between Load-Shedding Shifts

When K-Electric restores grid electricity for just 1 or 2 hours between outages, traditional batteries fail to recharge completely. The Dongjing 51V 100Ah module supports high charging currents up to 100 Amperes. This allows the battery pack to reach full capacity in a fraction of the time needed by old-style batteries, so you are always prepared for the next power breakdown.

3. 90% Usable Depth of Discharge (DoD)

With ordinary tubular batteries, discharging below 50 percent damages internal lead plates and shortens their lifespan. Dongjing lithium technology allows you to safely use up to 90 percent of its total 5.12kWh stored energy without causing degradation. You get almost double the usable backup duration compared to a similar-sized lead-acid setup.

4. Intelligent BMS with Smart Digital Screen

Safety is essential for indoor home energy storage. Dongjing equips every unit with an advanced internal Battery Management System (BMS) and a clear front digital LCD display. The BMS guards against overcharging, over-discharging, short circuits, high temperatures, and cell voltage imbalance. The front display lets you check voltage, current, and battery capacity easily.

5. Space-Saving Wall-Mounted Design

Floor space is often limited in modern Karachi apartments, townhouses, and tight utility rooms. Dongjing features a sleek, compact wall-mounted casing. It mounts securely to concrete walls, keeping your floor clear while protecting the equipment from accidental water splashes or dust accumulation.

Key Product Features

• Universal Inverter Compatibility: Supports RS485 and CANbus communication protocols. Works seamlessly with top hybrid inverters in Karachi, including Nitrox, Deye, Solis, Growatt, GoodWe, and Voltronic.

• Maintenance-Free Operation: Sealed solid-state construction means zero acid fumes, zero liquid leakage, and zero distilled water top-ups.

• Parallel Capacity Expansion: Allows multiple Dongjing 51.2V 100Ah units to be connected in parallel, letting you expand your energy storage smoothly as your power needs grow.

• Stable High-Voltage Output: Maintains consistent 51.2V nominal output during discharge, preventing heavy home appliances from tripping or underperforming.

• Environmentally Safe: Constructed using clean LiFePO4 material that produces no toxic emissions, making it safe for indoor residential installation.

Technical Specifications

What Can You Power with a Dongjing 51V 100Ah Lithium Battery?

When connected to a 3.6kW, 5kW, or 6kW hybrid solar inverter, a single 5.12kWh Dongjing battery comfortably keeps your daily home essentials running smoothly through power cuts:

• 1 Inverter Air Conditioner (1.5 Ton unit running efficiently for 3 to 4 hours)

• 4 to 6 Energy-Efficient Inverter Ceiling Fans

• 8 to 12 LED Lights and Fixtures

• 1 Refrigerator or Deep Freezer

• Wi-Fi Internet Routers, Laptops, Mobile Chargers, and Smart TVs

Pro Tip: If you want full-night backup for two inverter air conditioners and other continuous appliances during extended Karachi load-shedding hours, connecting two Dongjing 51V batteries in parallel doubles your usable storage to over 10kWh.

Frequently Asked Questions (FAQs)

Q1: Can I connect the Dongjing 51V lithium battery to my existing 48V solar inverter?

Yes. The Dongjing battery operates at a nominal 51.2V platform, which is designed to work directly with standard 48V hybrid and off-grid solar inverters used across Pakistan.

Q2: How is this Dongjing lithium battery better than tubular batteries for Karachi weather?

LiFePO4 lithium batteries handle warm room temperatures better, charge up to four times faster, deliver almost double the usable power per cycle, and last over 10 years compared to the 2 to 3 year life of tubular batteries.

Q3: How many hours of backup will this 5.12kWh battery provide?

Backup duration depends on your total household load. For a typical load of 500 Watts, one Dongjing 5.12kWh unit provides around 8 to 9 hours of uninterrupted power backup.

Q4: Is the installation process difficult?

No. The unit features built-in wall mounting brackets, heavy-duty terminal posts, and plug-and-play communication ports for quick and clean installation.
