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 CBAK 26650 is rated for a 5C continuous discharge, which equates to a stable 18A discharge current. This makes it suitable for high-drain devices like high-torque power tools and emergency start power supplies.

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 6-Pack?
A4: The 6-Pack offers excellent flexibility for professional and DIY users. You can use all 6 cells to build a 12V or 24V custom battery pack (4S2P or 8S), or keep a large backup reserve for multiple devices.

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.
