Rechargeable 20V Lithium-Ion Battery (FBLI20021) – High Capacity 4.0Ah | INGCO

INGCO 20V 4.0Ah High-Capacity Lithium-Ion Battery

Keep your tools running at full power with the INGCO P20S 4.0Ah Battery. Designed for professionals who need extra runtime, this battery delivers long-lasting energy for heavy-duty tasks. It is the heart of the INGCO cordless system, designed to work across hundreds of different tools.

Efficiency & Power

• 4.0Ah High Capacity: This battery stores double the energy of a standard 2.0Ah battery. It’s the best choice for high-drain tools like angle grinders, circular saws, and rotary hammers that need a lot of power for a long time.

• P20S Universal Fit: The “One Battery Fits All” system. This single battery is fully compatible with every tool in the INGCO 20V P20S range. You don’t need a different battery for every tool—just swap and go!

• Lithium-Ion Technology: Advanced cell technology ensures no memory effect. You can charge it at any time, even if it’s only half-empty, without damaging the battery’s lifespan.

Smart Features

• LED Power Indicator: Features a built-in 3-level LED light that shows you exactly how much charge is left at the press of a button. Never get caught with a dead battery in the middle of a job again.

• Rapid Heat Dissipation: The outer casing is designed to keep cells cool, protecting the battery from overheating during heavy use in hot workshop conditions.

• Deep Discharge Protection: Built-in smart sensors prevent the battery from draining too low, which extends the total life of the battery by years.

Why Choose the 4.0Ah Version?

• Work Longer: Ideal for full-day projects where you don’t have easy access to a charger.

• More Torque: High-capacity batteries often help high-torque tools (like impact wrenches) perform at their maximum strength.

• Value for Money: One 4.0Ah battery is often more convenient and cost-effective than carrying multiple smaller batteries.

Best Use Cases

• Professional Job Sites: Essential for heavy cutting and drilling where power is needed all day.

• Outdoor Use: Perfect for cordless garden tools or mobile repairs where power outlets are not available.

• Tool Kits: The perfect upgrade for any existing INGCO 20V tool kit to double your working time.
