The Ultimate Powerhouse Bundle: LiitoKala Lii-600 & The Legendary Lii-50A!
We have combined the industry-leading LiitoKala Lii-600 Smart Battery Charger & Tester with 4x Genuine LiitoKala Lii-50A 26650 Batteries. This isn't just a charger and some batteries—it's a complete, professional-grade power management system for the most demanding users, outdoor enthusiasts, and industrial technicians.
The Battery - LiitoKala Lii-50A:
The Lii-50A is a monstrous 26650 high-drain power cell. With a massive 5000mAh capacity and an astonishing 25A continuous discharge current, it unleashes raw power for extreme devices. Its ultra-low 22mΩ internal resistance ensures minimal heat generation and stable voltage even under brutal loads. Built to endure extreme environments, it operates flawlessly from -30℃ to 60℃, retaining 70% capacity even at -10℃!
The Charger - LiitoKala Lii-600:
The Lii-600 is a supercharged, touch-screen 4-slot charger that goes far beyond simple charging. It features a massive 3A super fast charging current per slot, professional-grade Internal Resistance (mΩ) Testing (perfect for verifying your 26650 cells), Capacity Testing, and Battery Repair.
IMPORTANT NOTES:
Battery Top Type: Please select Button Top (for standard spring-loaded flashlights/vapes) or Flat Top (for spot welding, or devices with very tight springs) based on your device's requirements. Button Top adds ~2mm length. Please check your device bay depth!
Plug Options: This kit comes in CN/US, EU, and UK plug variants. Please select the correct plug type for your region before ordering.

Professional Battery Testing: Use the Lii-600 to verify capacity, internal resistance, and overall health of your expensive cells.
Q1: What is the difference between Button Top and Flat Top?
A1: Flat Top cells have a completely flat positive end, used for spot-welding into custom packs or devices with extremely tight springs. Button Top cells have a small protruding button, designed for standard spring-loaded contacts. Note: Button Top adds approximately ~2mm length. Please check your device's battery bay depth before ordering!
Q2: Is this battery safe for extreme high-drain devices?
A2: Absolutely! The Lii-50A is engineered for high-drain usage, featuring an ultra-low 22mΩ internal resistance and a stable 25A continuous discharge current, ensuring your devices get consistent power without overheating.
Q3: How does the Lii-600 help ensure my batteries are genuine?
A3: The Lii-600 features a professional internal resistance tester. By measuring the resistance (≤30% error), you can instantly assess if a battery is healthy or a degraded/fake cell.
Q4: Can I charge all 4 batteries at 3A simultaneously?
A4: Yes, if you manually set the charging current to 3000mA on all slots. In AUTO mode, it will safely detect each battery's internal resistance and capacity to assign the optimal charging speed.
Q5: What happens if the batteries get too hot while charging?
A5: The Lii-600 features smart temperature monitoring. If the temperature rises above 65°C, the charger will automatically reduce the charging current to protect the battery.
