Key Features & Benefits

• Massive 10400mAh Capacity – 4× the Runtime: Four high-quality 18650 cells connected in parallel multiply capacity while maintaining a safe, stable 3.7V output. Enjoy up to four times longer operation compared to standard single-cell batteries – perfect for power‑hungry portable electronics.

• 1S4P Parallel Design for Enhanced Reliability: The 4P parallel structure not only boosts capacity but also reduces internal resistance and distributes load evenly across cells. This results in cooler operation, improved current capability, and extended overall pack life.

• Built-in Protection Circuit Module (PCM): Equipped with a precision-engineered PCM that guards against over-charge, over-discharge, over-current, and short circuits. The R1 protection board is optimised for 1S4P packs, ensuring safe and stable performance even under demanding conditions. 

• Compact, Durable & Ready-to-Use: Housed in a robust PVC sleeve, with pre‑attached nickel tabs or customisable output leads. The pack is fully assembled, tested, and ready for seamless integration into your product or project.
