Frequently Asked Questions (FAQ):
Q1: Can I solder wires directly to this battery?
A1: NO. This is a bare cell without a protection board. Do NOT use a soldering iron to connect wires directly to the battery terminals. This battery requires spot welding with nickel strips for connection. Using a soldering iron will permanently damage the battery.
Q2: What is the discharge current of this battery?
A2: This Soshine IFR18650 has a powerful 9A max continuous discharge current (with an 18A pulse capability). This makes it highly suitable for high-drain devices like gel blasters, RC models, and power tools.
Q3: What is the advantage of the ultra-low 25-30mΩ internal resistance?
A3: Ultra-low internal resistance means the battery generates very little heat during high-current discharge. More power reaches your device, and the battery stays cool, extending its lifespan.
Q4: Is this battery suitable for RC models and drones?
A4: Absolutely. With its 9A continuous discharge (18A pulse) and high energy density, it provides the instant power required for high-torque RC cars and drones.
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.
