Frequently Asked Questions (FAQ):
Q1: What is the discharge current of this battery?
A1: This A123 ANR26650M1B is rated for an astonishing 70A continuous discharge current, making it one of the highest-performing 26650 cells available. It is designed for high-torque power tools and electric vehicles.
Q2: What is the advantage of the 6mΩ ultra-low internal resistance?
A2: 6mΩ is exceptionally low for a 26650 cell. This means the battery generates virtually no heat during 70A high-current discharge, maximizing performance and protecting your equipment.
Q3: What is the cycle life of this battery?
A3: This A123 cell is designed to withstand over 1000 full cycles, even under high-temperature and high-load conditions, maintaining reliable performance over a very long lifespan.
Q4: Can I use this battery in standard 26650 flashlights?
A4: Yes, it fits standard 26650 compartments. However, it is optimized for high-drain applications. For simple low-power devices, lower-discharge cells may be more cost-effective.
Q5: What kind of charger should I use for this battery?
A5: You must use a charger specifically designed for 3.2V/3.3V LiFePO4 batteries with a 3.65V cut-off voltage. Do not use a standard 3.7V/4.2V Li-ion charger. We recommend using a smart charger with a balanced charging feature.
