Spektrum 1400mAh 2S 7.4V Smart G2 30C LiPo Battery IC2 SPMX142S30H2

Power compatible small-scale RC vehicles with the compact Spektrum 1400mAh 2S Smart G2 LiPo Battery. Designed with a 7.4V two-cell configuration, 30C discharge rating and compact hard-case construction, this battery provides reliable power and practical runtime for platforms including compatible ARRMA GROM vehicles.

Spektrum Smart G2 technology stores important battery information on an integrated microchip and allows compatible Smart chargers to identify the pack automatically. Charging and cell balancing are handled through the single IC2 connection, eliminating the need for a separate external balance lead.

FAQ

Will this battery fit the ARRMA Granite GROM? Yes. It is designed for compatible ARRMA GROM platforms, including the Granite GROM MEGA 380 ARA2102. Always confirm the vehicle's battery tray, voltage rating and connector before ordering.

Does this battery have a balance lead? No. Spektrum Smart G2 batteries charge and balance through the main IC2 connection, so there is no separate conventional balance plug.

What charger is required? Use a Spektrum Smart charger that supports Smart G2 batteries, together with an IC2-compatible charge connection or an appropriate Smart-compatible adaptor.

Can I charge it with a standard non-Smart LiPo charger? A conventional charger cannot normally balance this Smart G2 pack because the battery has no external balance lead. Use a compatible Spektrum Smart G2 charging setup.

What information does Smart G2 technology store? The integrated microchip can store battery information including chemistry, capacity, discharge rating, individual cell voltage, temperature and charge-cycle data for access through compatible Spektrum Smart equipment.

Does the battery discharge itself for storage? Smart G2 batteries include an automatic storage-discharge feature. The discharge timing and target behaviour may be adjustable through compatible Smart charging equipment.

Will the IC2 connector plug into EC2? IC2 and EC2 are designed around the same compact connector size, but full Spektrum Smart functionality requires a compatible Smart connection. Confirm connector polarity and compatibility before use.

Can I use this in any 2S RC vehicle? Only when the vehicle supports a 7.4V 2S LiPo, has sufficient battery-tray space and uses a compatible connector. Battery dimensions and weight should also be checked.

How long will the battery run? Runtime depends on the vehicle, motor, gearing, terrain, driving style and battery condition. A 1400mAh pack generally offers practical runtime for compact platforms such as the ARRMA GROM range.

Does the 30C rating increase top speed? Top speed is primarily determined by battery voltage, motor, ESC, gearing and tyre diameter. The 30C rating indicates the battery's discharge capability rather than a guaranteed speed increase.

Can I use an adaptor between the battery and vehicle? A correctly rated adaptor may be used where appropriate, but it must maintain correct polarity and be suitable for the required current. Additional adaptors can add resistance and take up space inside a compact battery compartment.

How should the battery be stored? Store it at an appropriate LiPo storage voltage in a cool, dry and fire-resistant location. Avoid leaving the pack fully charged for extended periods, even though the Smart discharge feature provides additional storage support.

Important Notes

• Confirm your vehicle supports a 7.4V 2S LiPo battery before installation.
• Check the battery tray dimensions and IC2 connector compatibility before ordering.
• A compatible Spektrum Smart G2 charger and suitable IC2 connection or adaptor are required.
• This Smart G2 battery does not have a separate conventional balance lead.
• Always inspect the battery, wires and connector before use.
• Never use or charge a swollen, punctured, crushed, overheated or otherwise damaged battery.
• Never leave a LiPo battery unattended while charging.
• Charge on a non-flammable surface and use a suitable LiPo charging enclosure or bag.
• Confirm connector polarity before connecting the battery or an adaptor.
• Ensure the vehicle's LiPo low-voltage cutoff is enabled.
• Allow the battery to cool before recharging after use.
• Keep the battery away from water, excessive heat, children and combustible materials.
• Dispose of damaged or end-of-life LiPo batteries through an appropriate battery recycling service.
