Frequently Asked Questions
- What vehicles are compatible with the Spektrum 7.4V 1400mAh 2S 30C Smart G2 LiPo Battery? — This battery is compatible with any RC vehicle designed for 2S LiPo packs, including the ARRMA GROM range, and any model featuring an IC2 connector input. It works with brushed and brushless motors, making it suitable for most small-scale ready to run RC vehicles. Always check your vehicle's manual to confirm 2S LiPo compatibility before connecting this battery.
- What charger do I need to use with this Smart G2 battery? — This battery is designed to work with Spektrum Smart chargers, such as the Spektrum S100 1x100W USB-C Smart Charger or the Spektrum S155 55W AC G2 Smart Charger. These chargers automatically recognise the battery's parameters and apply correct charging settings. You can technically charge this battery with non-Smart chargers, but you will lose all Smart technology benefits and must manually configure charge settings yourself.
- How long does this battery take to charge? — Charge time depends on which charger you use and which charge rate you select (1A, 2A, 3A, or 6A). With a 1A charge rate, expect approximately 1.4 hours; with a 6A rate and sufficiently powerful charger, charging could complete in under 15 minutes. The battery remembers your last selected charge rate, so you won't need to reprogram settings for future charges.
- Is this battery suitable for beginners? — Yes, absolutely. The Smart G2 technology makes this battery ideal for beginners because the integrated microchip eliminates the need to manually configure charging parameters. Simply connect the battery to a Spektrum Smart charger and it handles everything automatically. The detailed error logging and temperature monitoring also provide peace of mind for less experienced users who may be unfamiliar with battery safety practices.
