Benson QGL-S 12.8V/60AH Lithium Battery (LiFePO4)

Benson QGL-S 12.8V/60Ah Plastic Case Lithium Battery (LiFePO4) Price in Bangladesh.

The Benson QGL-S 12.8V/60Ah Lithium Battery (LiFePO4) is a reliable power solution for homes, offices, solar systems, and portable energy devices in Bangladesh. Built with advanced LiFePO4 chemistry, it delivers higher usable capacity, faster charging, and thousands of cycles—far outperforming lead-acid batteries. Its durable plastic case keeps weight low and protects against heat and humidity, making installation easier in tight spaces like telecom cabinets, UPS systems, CCTV setups, boats, and RVs. For areas with frequent load-shedding, voltage drops, or long backup demands, the Benson QGL-S ensures stable output, minimal maintenance, and long-term cost savings, making it a strong choice for anyone seeking dependable battery performance in Bangladesh.

If you want a compact and long-lasting energy storage solution for solar, UPS, telecom or portable power units, the Benson QGL-S 12.8V/60Ah LiFePO4 battery hits a sweet spot in performance, safety and efficiency. It’s built with Lithium Iron Phosphate (LiFePO4) chemistry, which is far more stable than traditional lead-acid batteries and does not degrade quickly, even under heavy use.

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.

Performance Advantages for Bangladesh

Let’s be practical. Power outages, voltage instability and frequent cycling are common here. Lead-acid batteries fail fast under these conditions. The Benson QGL-S LiFePO4 battery gives:

• Stable supply in high heat and humid environments

• Better deep-cycle tolerance for solar net metering or hybrid inverter systems

• Lower cost over time because it lasts 4–6x longer than standard VRLA or GEL batteries

• Compact form factor to fit home office, shop or industrial control panel installations

Safety that gives peace of mind

LiFePO4 chemistry is inherently safer than other lithium types. It resists overheating, fire propagation, and thermal runaway. With built-in protections (overcharge, over-discharge, short-circuit), it keeps your inverter, solar controller and connected appliances protected.

Who should use this battery?

• Home solar users who want reliable night-time backup

• Corporate offices & SMEs running UPS and routers

• Telecom installations that require lightweight, stable backup

• Retail POS systems and CCTV setups where downtime costs money

• Outdoor users like food trucks, campers, and portable power applications
