Spektrum Smart G2 4S 5000mAh 100C LiPo Battery IC5 SPMX54S100H5

The Spektrum SPMX54S100H5 is a 14.8V 4S 5000mAh Smart G2 hardcase LiPo battery for compatible surface RC vehicles, combining a 100C discharge rating with IC5 connectivity and single-connection Smart balance charging.

Features

• Smart G2 Technology: Integrated memory stores battery parameters, operating data and charge history for use with compatible Spektrum Smart equipment
• Single-Connection Charging: Balance information travels through the IC5 connector data wire, eliminating the separate balance lead found on conventional LiPo packs
• 100C Discharge Rating: Designed for high-current surface RC applications requiring strong power delivery
• Automatic Storage Discharge: Factory programmed to discharge toward 3.90V per cell after 72 hours of inactivity, with settings adjustable through compatible Smart equipment
• Faster Auto Storage: Smart G2 technology supports automatic storage discharge at up to 1.5A
• Hardcase Construction: Protective outer case suits demanding RC car, truck and boat applications
• Internal Metal Side Plates: Thicker internal plates provide additional cell protection and assist heat dissipation
• IC5 Connector: High-current Spektrum connector with Smart data functionality and physical compatibility with EC5-style connections
• 10AWG Wiring: Heavy-gauge power leads support the pack's high-current surface application

FAQ

Is SPMX54S100H5 a 3S or 4S battery? SPMX54S100H5 is a 4S LiPo battery with a nominal voltage of 14.8V. Some older retailer specification tables incorrectly list three cells, but Spektrum's current product data confirms four cells.

Can this Smart G2 battery be charged with a normal LiPo charger? No. Smart G2 batteries do not have a conventional separate balance lead and require a compatible Spektrum Smart charger with G2 support for correct charging and cell balancing.

Will the IC5 connector work with an EC5-equipped RC vehicle? Yes. Spektrum states that IC5 connectors are physically compatible with EC5-style connectors. Smart telemetry or data functions require compatible Smart equipment and the IC data connection.

What is the maximum charging rate? Spektrum's current product data lists both a 5A maximum charge current and a 5C maximum charge rate, which are mathematically inconsistent for a 5000mAh pack. OZRC recommends following the conservative 5A manufacturer-listed current limit and the instructions provided by the compatible Smart charger unless Spektrum publishes revised guidance.

Important Notes

• Use only a compatible Spektrum Smart charger with Smart G2 support
• Confirm the vehicle supports 4S LiPo power before installation
• Check the 138 x 46 x 35mm battery dimensions against the vehicle battery tray
• Never charge a damaged, swollen or excessively hot LiPo battery
• Charge LiPo batteries in a suitable fire-resistant charging area and follow Spektrum's battery safety instructions
• Spektrum's current product page lists 55.5Wh, but 14.8V x 5Ah calculates to approximately 74Wh; verify the physical battery label where watt-hour information is required for transport or compliance purposes
