Frequently Asked Questions (FAQ):
Q1: Is the 7000mAh capacity truly real?
A1: Absolutely. The LiitoKala Lii-70S has been independently tested using a professional capacity meter. The measured capacity consistently reaches 7085mAh, exceeding the advertised 7000mAh rating. No inflated numbers, just real performance.
Q2: What is the difference between Button Top and Flat Top?
A2: This battery features a Button Top, with a protruding positive terminal that is 2mm taller than the Flat Top version (67.3mm vs 65.3mm). The protruding button ensures a more reliable connection in devices with recessed battery contacts or spring-loaded compartments. Choose Button Top if your device requires a raised contact point.
Q3: What is the advantage of the ultra-low 17mΩ internal resistance?
A3: An ultra-low internal resistance of 17mΩ means the battery generates significantly less heat and loses minimal energy during high-current discharge. More power reaches your device, and the battery stays cooler, extending its lifespan.
Q4: What is the discharge current of this battery?
A4: This LiitoKala Lii-70S is rated for a powerful 21A (3C) continuous discharge current, making it ideal for high-drain devices such as power tools, flashlights, and drones.
Q5: How do I choose the right pack size?
A5: Choose the 1 or 2 Pack for personal use or as a spare. Choose the 4, 5, 6, or 8 Pack for building custom battery packs or for multi-device households. Choose the 10 Pack for professional bulk assembly or workshop projects.
