The stock Zeus motors are designed to run reliably at 9 volts (six 1.5 volt C cells). Modders frequently use 3S LiPo battery packs in the Zeus, which produce 11.1 volts at significantly higher current. For the most part, 3S in a Zeus does not require rewiring or improved switches.

That being said, Nerf motors have historically been able to handle twice the stock voltage. By that measure, the Zeus motors should be able to handle 18 volts, but the longevity will be somewhat decreased. Running under load for long periods at these voltages will definitely damage the stock Zeus motors.

But if you're asking what the absolute maximum voltage is, it's probably around 36 volts. We already know the 9 volt Vulcan motors can operate at that voltage for about a minute. The real problem is heat dissipation. Without a method for dealing with the excessive heat, motors literally burn out because they get too hot.

Please note, the Zeus has a thermistor. It may have to be removed for a 3S pack, and will definitely need to be removed for higher voltages. Individual results vary. At higher voltage, the rev switch is also a weak link. It may need to be replaced with a decent 10amp switch like an Omron. At really high voltages you'll have to consider MOSFET.

Hopefully this was helpful 😊
