❓ FAQ – 6.6V 2100mAh LiFe Receiver Battery
🔋 Q1: What is a LiFe receiver battery, and why choose 6.6V LiFePO₄?
A LiFe receiver battery uses Lithium Iron Phosphate (LiFePO₄) chemistry, known for its high safety, long cycle life (3000+ cycles), and stable voltage output. The 6.6V nominal voltage is perfect for RC receivers and servos, providing consistent performance without overvoltage risks seen in Li-ion packs.
🔒 Q2: Is this battery safe to use in RC models and industrial equipment?
Yes. LiFePO₄ chemistry has an extremely low risk of fire or explosion, even under abuse conditions. It is thermally and chemically stable, making it safer than Li-ion batteries for RC airplanes, cars, helicopters, robotics, and control systems.
🌡 Q3: Can the battery handle high-temperature environments?
Absolutely. This pack is designed to work reliably up to 70°C, making it suitable for summer racing, outdoor industrial use, and hot climates without significant capacity loss.
🔁 Q4: How long does this battery last?
Under proper care, this LiFePO₄ battery delivers over 3000 charge-discharge cycles—3–5 times more than typical Li-ion or NiMH packs. That means years of dependable operation before replacement is needed.
⚡ Q5: Does it have memory effect?
No. You can recharge this battery at any time, even when it’s partially discharged, without reducing capacity. This flexibility is ideal for events or work where you need quick top-ups.
🔌 Q6: What connectors are available?
Standard options include JR, Futaba, XT60, Deans, and other common RC plugs. We also provide OEM/ODM customization for connector type, wire length, and protective housing.
