Dual-Purpose Design: RX & TX Battery

This 2100mAh 2S LiFe (LiFePO4) pack is engineered as a versatile solution: it works both as a receiver battery (RX pack) in large-scale RC aircraft and as a transmitter battery (TX pack) for radios that support EC3 input. The EC3 connector makes it ideal for modern Spektrum NX/iX transmitters, while the included JST lead supports receiver systems, onboard accessories, and field charging setups.

Why Choose LiFe (LiFePO4)?

LiFe batteries—also called LiFePO4 packs—deliver a flat 6.6V output curve from start to finish. Compared to NiMH packs, they maintain servo response and radio link quality with less voltage drop; versus LiPo, they provide a safer operating chemistry for sensitive RC electronics. With CNHL’s superior reliability and performance and low internal resistance, this pack ensures cooler running, higher efficiency, and dependable power for both flight control systems and transmitters.

Application Examples

• Spektrum TX (EC3): NX6, NX8, NX10, iX12 radios (check tray size and polarity before use).
• Receiver Pack (RX): 1.5–1.7m RC warbirds, EDF jets, and RC helicopters needing stable 6.6V power.
• Accessory Power: JST lead can run lights, ignition modules, or other onboard systems.

Charging & Safety

• Charge only with a balance charger in LiFe / LiFePO4 mode.
• Do not exceed 3.65V per cell (normal range: 3.2–3.65V per cell).
• Always check pack voltage and condition before each use.
• If capacity seems low, cycle charge/discharge several times to balance cells.
• Store at 50–60% capacity for long-term storage; avoid short-circuit, crushing, or overheating.
