Product description

Battery & charger choices

Battery and charger sold separately. These options use one full-size IC5/EC5 hardcase pack.

Choose one charger: S1100 G2 100W AC — lower-cost 6S-capable choice or S2100 G2 dual 100W AC — charge two packs at once.

Battery choices: Spektrum 5000mAh 4S 100C Smart G2, IC5 — lower-voltage option or PowerHobby 5000mAh 6S 100C hardcase, EC5 — full 6S performance. Use one of these packs, not both together.

Setup note: On an ESC with two battery inputs, use the vehicle’s IC5 loop connector in the unused input for a single-pack setup. The PowerHobby pack needs both its main lead and JST-XH balance lead connected to the charger. Both recommended chargers support a single 6S pack.
