Frequently Asked Questions
- Is this battery compatible with my Futaba or Hitec RC transmitter? — Yes, absolutely. The Radient LiFe 2S 6.6V 2100mAh 15C battery is specifically engineered for Futaba and Hitec transmitter systems. The 2-cell 6.6V configuration delivers the exact voltage specification these transmitters require, and the compact 95mm x 43mm x 13mm dimensions fit standard transmitter battery compartments without modification.
- What is LiFe chemistry and why is it better than NiMH? — LiFe (Lithium Iron Phosphate) technology is a modern advancement in battery chemistry that offers significantly longer cycle life, faster charging times, and more stable voltage output compared to older Nickel Metal Hydride (NiMH) batteries. This means your transmitter will perform more reliably and the battery will last considerably longer before requiring replacement.
- How long will this battery power my RC transmitter? — The 2100mAh capacity provides extended operating time for typical RC sessions. Runtime depends on your specific transmitter's power consumption, but this capacity is sufficient for many hours of RC car, RC truck, and RC vehicle operation. Many UK RC enthusiasts keep this as a spare battery to ensure continuous operation throughout the day.
- What does the 15C discharge rating mean? — The 15C rating indicates the continuous discharge current the battery can safely deliver. For a 2100mAh battery, this means it can safely provide up to 31.5 amps of continuous current, ensuring stable power delivery to your transmitter's electronics during intensive RC use.
- Can I use this battery with other RC transmitter brands? — This battery is specifically optimised for Futaba and Hitec transmitter systems with 2S (6.6V) battery specifications. If your transmitter uses a different voltage specification, you should verify compatibility before purchase to avoid potential damage to your RC radio equipment.
- Is this battery suitable for beginners in the RC hobby? — Absolutely. This is a straightforward battery pack with no complex requirements. If you own a Futaba or Hitec transmitter that uses 2S LiFe or equivalent batteries, this Radient pack will work reliably. Simply charge it according to your transmitter's instructions and insert it into your RC radio system.
- How much does this transmitter battery weigh? — The complete battery pack weighs just 90 grams (3.17 ounces), making it lightweight and portable whilst still delivering substantial capacity for extended RC sessions.
