FAQ

What vehicles can use the Spektrum SPMX53S100H5 battery? This battery is intended for RC surface vehicles that support 11.1V 3S LiPo power, have sufficient battery compartment space for a 138 x 46 x 35mm pack and use a compatible IC5 or EC5 power connection. Always check your vehicle and ESC specifications before use.

Does this battery need a separate balance lead? No. Spektrum Smart G2 batteries transmit balancing information through the Smart connector, allowing compatible Spektrum G2 chargers to balance charge using a single connection.

Can I charge this battery with a standard LiPo charger? Smart G2 batteries do not have a conventional external balance lead. Use a compatible Spektrum Smart G2 charger or an earlier Spektrum Smart charger updated for G2 battery support.

What is the difference between Spektrum Smart G1 and G2 batteries? Smart G2 batteries use single-connector balance charging and offer improved automatic storage discharge performance. G2 batteries require a charger with G2 support.

What does the 100C rating mean? The 100C rating describes the manufacturer's specified continuous discharge capability relative to battery capacity. For a 5000mAh pack, this corresponds mathematically to 500A, although actual usable current is limited by the battery, connectors, wiring, temperature and application.

Does the Spektrum Smart G2 battery discharge itself for storage? Yes. The factory setting starts automatic discharge towards 3.90V per cell after 72 hours of inactivity. The delay and storage settings can be adjusted using a compatible Spektrum Smart charger.

Is the IC5 connector compatible with EC5? IC5 connectors are designed to be electrically compatible with corresponding EC5-style connectors. Smart communication features require compatible Spektrum Smart equipment.

Is this a hardcase battery? Yes. This model uses a protective hardcase designed for RC surface vehicles.

Can I use this 3S battery in a 2S-only RC car? No. An 11.1V 3S LiPo must only be used in a vehicle and ESC specifically rated for 3S operation.

Is this battery ROAR approved? No. The manufacturer lists this battery as not ROAR approved. Check your racing organisation's battery regulations before competition use.
