Frequently Asked Questions (FAQ):
Q1: What is the advantage of LiFePO4 chemistry?
A1: LiFePO4 (Lithium Iron Phosphate) offers superior thermal stability, a much longer cycle life (2000+ cycles), and enhanced safety. It is less prone to overheating, explosion, or fire under extreme conditions compared to standard lithium-ion batteries.
Q2: What is the discharge current of this battery?
A2: The Ruisai IFR26650 is rated for a 3C continuous discharge, which equates to a stable 10.8A discharge current. This makes it suitable for high-drain devices like high-power flashlights and power tools.
Q3: How many times can I recharge this battery?
A3: LiFePO4 batteries are renowned for their longevity. This battery supports over 2000 full recharge cycles (retaining 80% capacity after 2000 cycles), providing exceptional long-term value.
Q4: Why is this product sold as a 2-Pack?
A4: The 2-Pack offers excellent flexibility. You can use both cells for high-power applications requiring matched cells, or keep one as a backup while using the other for daily operations.
Q5: What kind of charger should I use for this battery?
A5: You must use a charger specifically designed for 3.2V LiFePO4 batteries with a 3.65V cut-off voltage. Do not use a standard 3.7V/4.2V Li-ion charger.
