Frequently Asked Questions (FAQ):
Q1: What is the discharge current of this battery?
A1: This Tesla 4680 cell is rated for a 3C discharge rate. With a 23Ah capacity, this translates to a stable 69A continuous discharge current, providing immense power for high-performance applications.
Q2: Does this battery come with tabs or wires attached?
A2: This product is sold as a bare cell. The spec sheet clearly notes: "Can be customized according to requirements with tabs, wires, or terminals." Please contact us to discuss your specific custom welding or configuration needs.
Q3: What is the advantage of the 4680 format over other cylindrical cells?
A3: The 4680 (46mm diameter x 60mm height) is Tesla's revolutionary large-format cell. It provides significantly higher energy capacity (23Ah) and better thermal management than smaller cells like 18650 or 21700, making it ideal for large-scale power applications.
Q4: What kind of charger should I use for this battery?
A4: You must use a charger specifically designed for 3.7V Li-ion batteries with a 4.2V cut-off voltage. For a single cell, a dedicated 4680 or 21700/18650 charger capable of delivering up to 2A (2000mA) is recommended.
Q5: Can I use this battery to build a 12V battery pack?
A5: Yes. For a standard 12V system, you would connect 3 cells in series (3S) to achieve 11.1V nominal. Always use a BMS (Battery Management System) when building custom packs to ensure safety and balance.
