Benson QGL-S 12.8V/80AH Lithium Battery (LiFePO4)

Benson QGL-S 12.8V/80Ah Plastic Case Lithium Battery (LiFePO4) Price In Bangladesh

The Benson QGL-S 12.8V/80Ah Lithium Battery (LiFePO4) is a high-capacity, reliable power solution designed for homes, offices, solar systems, and portable energy needs in Bangladesh. Its advanced LiFePO4 chemistry ensures faster charging, longer lifespan, and stable performance even under deep discharge, outperforming traditional lead-acid batteries. Housed in a durable plastic case, it resists heat, moisture, and corrosion, making it ideal for installation in solar cabinets, UPS systems, telecom racks, or mobile setups like RVs and boats. With built-in protection against overcharge, over-discharge, and short circuits, the Benson QGL-S 80Ah delivers consistent, maintenance-free power, ensuring uninterrupted electricity during outages while reducing long-term energy costs.

If you’re looking for a dependable energy storage solution that can handle daily loads, the Benson QGL-S 12.8V/80Ah LiFePO4 is built for real-world usage in Bangladesh. This model sits in the sweet spot of capacity and efficiency—large enough for home or office backup, yet compact and easy to install. With Lithium Iron Phosphate technology, you get a battery that runs cooler, charges faster, and lasts significantly longer than traditional lead-acid options.

Why this Battery Matters

• High usable capacity
  You get the full rated power. Unlike lead-acid where usable capacity drops after 50 percent discharge, LiFePO4 delivers consistent output even at deep discharge levels.

• Ultra-long lifecycle
  Benson QGL-S can reach thousands of charge cycles, making it ideal for daily cycling applications such as solar systems or energy backup.

• Lightweight plastic case
  A strong, heat-resistant plastic shell keeps weight low and makes installation easier in homes, shops, RVs, boats and industrial cabinets.

• Fast recharge
  Lithium technology charges faster and wastes less energy, reducing generator runtime and panel waiting time.

• Low maintenance
  No “water topping”, no acid fumes and virtually no internal corrosion — just plug and run.

Why this 80Ah model stands out

The 80Ah capacity means longer runtime for inverters, routers, lights, fans, refrigerators, or CCTV systems during power outages. Unlike lead-acid batteries that lose strength after 50 percent discharge, LiFePO4 batteries maintain steady performance even under deep cycles. Benson’s built-in BMS (Battery Management System) actively protects against over-voltage, over-current, short circuit, and overheating, extending the battery’s useful life.

Designed for Bangladesh conditions

Heat, humidity and frequent load shedding are normal here. The QGL-S comes in a rugged plastic case that resists shock, moisture and corrosion. Whether it’s installed in a solar cabinet, office UPS box, telecommunication rack or rural home, it performs consistently without the maintenance hassles of GEL or VRLA units. You won’t need to refill water or worry about acid fumes—just plug and use.

Ideal for

• Solar energy systems (off-grid or hybrid)

• Home UPS or inverter backup

• Telecom and networking cabinets

• RV, marine power, camping and portable electricity

• Security systems, POS machines, small business backup

This is a battery that actually lowers cost over time. Instead of replacing lead-acid units every 1–2 years, the Benson QGL-S 80Ah delivers 3000+ cycles, offering 4–6 times longer service life and reduced electricity loss during charging.
