Frequently Asked Questions (FAQ):
Q1: What is the advantage of the 26700 size over the 26650?
A1: The 26700 is 5mm longer than the 26650 (70mm vs 65mm). This extra length allows for a higher capacity of 4000mAh, providing more energy storage in a similar diameter form factor.
Q2: What is the discharge current of this battery?
A2: The EVPS 26700 is rated for a 3C continuous discharge, which equates to a stable 12A discharge current. This makes it suitable for a wide range of medium-to-high power applications.
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 4-Pack?
A4: The 4-Pack is specifically designed for building standard 12.8V battery packs (4S configuration). You can connect 4 cells in series to achieve 12.8V, which is the most common voltage for portable power stations and solar storage systems.
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.
