Spectrum vs Gen’s Ace load test

In this Spectrum vs Gen’s Ace load test, we are comparing two high-performance 4S LiPo packs under a 105A continuous discharge to see which battery delivers better real-world RC performance.

On one side we have the Gen’s Ace 5300mAh 4S 60C G-Tech pack priced at $95.99 USD. On the other side we have the Spectrum Smart G2 5000mAh 100C pack priced at $135 USD with full smart telemetry integration.

This Spectrum vs Gen’s Ace load test focuses on real discharge performance, not just specs on paper. Let’s jump into the results.

Spectrum vs Gen’s Ace load test Battery

Battery Test Group / What Makes It Unique

This Spectrum vs Gen’s Ace load test uses a 105A continuous discharge to simulate high-demand RC conditions like speed runs and aggressive bashing.

We compare performance at:

  • Maximum current spike
  • 10-second sustained load
  • 30-second sustained load
  • Cutoff point

This gives a full picture of how each pack behaves under stress.

Internal Resistance

In this Spectrum vs Gen’s Ace load test, internal resistance is visible through voltage sag and sustained wattage drop.

The Gen’s Ace shows stronger mid-discharge stability, while the Spectrum Smart G2 holds slightly better voltage near cutoff.

Overall, the Gen’s Ace maintains more consistent efficiency under sustained high current.

Practical Uses

In this Spectrum vs Gen’s Ace load test, the Gen’s Ace is clearly better for high-current performance, longer runtime, and sustained output under load.

The Spectrum Smart G2 is better suited for users who value telemetry integration, smart features, and ecosystem compatibility.

Final Thoughts

From this Spectrum vs Gen’s Ace load test, the Gen’s Ace delivers better sustained power and significantly higher usable capacity under 105A load.

The Spectrum Smart G2 only wins at the very end of discharge, but cannot match the overall performance gap.

For performance per dollar, Gen’s Ace is the clear winner. For smart features and integration, Spectrum still has value.
