Product Description:
The Soshine 18650 is a premium-grade lithium iron phosphate (LiFePO4) rechargeable battery featuring a built-in intelligent protection board. This 2-Pack / 4-Pack bundle delivers a stable 2000mAh (2.0Ah) capacity, 6.4Wh of energy, and a reliable 6A continuous discharge current. The built-in protection board ensures safety against over-charge, over-discharge, and over-current, making it an ideal power source for flashlights, radios, portable power banks, and small appliances.
Manufactured with advanced LiFePO4 chemistry, this battery offers superior thermal stability, an ultra-long 2000-cycle lifespan, and enhanced safety. It operates reliably across a wide temperature range from -20°C to 60°C.

Frequently Asked Questions (FAQ):
Q1: Can I solder wires directly to this battery?
A1: NO. Please follow the warning in the product description. Do NOT use a soldering iron to connect wires to the battery terminals. This battery requires spot welding with nickel strips for connection. Soldering directly will melt the internal protection board and permanently damage the battery.
Q2: What is the advantage of the built-in protection board?
A2: The built-in protection board provides crucial safety features: over-charge protection (stops charging at 3.95V), over-discharge protection (stops discharge at 2.6V), and over-current protection (limits current to 7.5A). This prevents the battery from being damaged by misuse and extends its lifespan.
Q3: What is the discharge current of this battery?
A3: This Soshine 18650 has a max continuous discharge of 6A, with a protection board that cuts off at 7.5A. This makes it suitable for medium-drain devices like flashlights and portable power banks.
Q4: Is this battery safe to use in extreme temperatures?
A4: Yes. It is designed to discharge reliably from -20°C to 60°C and charge from 0°C to 55°C, making it suitable for both outdoor winter and hot summer use.
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.
