The Admiral Pro 5000mAh 4S 60C battery load test puts this pack up against the HRB 5000mAh and the Spektrum Smart G2 5000mAh 100C to see how it performs under demanding load conditions. The goal was to measure internal resistance, voltage stability, and overall energy/power delivery using a consistent 105-amp continuous discharge test.
| Battery | Price (USD) |
|---|---|
| Admiral Pro 5000mAh 4S | $75.99 |
| HRB 5000mAh 4S | $47.99 |
| Spektrum Smart G2 5000mAh 4S | $124.99 |
Each pack used EC5 or IC5 connectors and was tested under identical conditions—ambient temperature, charge rate (1.5C), and rest time before testing. This ensures a fair comparison and reliable data across all packs
Internal Resistance Results
During charging, the Admiral Pro 5000mAh 4S reached a total internal resistance of 11.8 mΩ, breaking down to 3.0, 2.7, 3.1, and 2.8 mΩ per cell. A second LiPo pack reading showed similar results, confirming consistent cell quality.
The Admiral Pro 5000mAh 4S showed tighter resistance consistency than both the HRB and the Spektrum Smart G2, indicating good cell matching and manufacturing quality.
Load Test Results (105A Continuous)
Two Admiral packs were tested under a 105A load, with the results averaged for comparison.
The 105A continuous load test is where the Admiral Pro 5000mAh 4S 60C really showed its character. The pack delivered 4157 mAh before reaching cutoff, with an average output power of 354W per cell.
Practical Uses
Given its performance and cost, the Admiral Pro 5000mAh 4S 60C battery is a solid mid-range choice for RC enthusiasts running setups that regularly pull between 90–105A. Its voltage stability under sustained load makes it suitable for higher load RC cars, boats, and EDF jets that demand consistent power delivery without excessive voltage sag.
While not as inexpensive as the HRB, it provides stronger mid-discharge voltage and a better energy curve, making it a worthwhile upgrade if you value consistent performance under stress.
Final Thoughts
In this Admiral Pro 5000mAh 4S 60C battery test, the pack demonstrated excellent internal consistency and strong load results that matched its calculated current capability. Compared to both the HRB and Spektrum Smart G2, it achieved higher usable capacity under load and better value overall, especially considering its moderate price point.
It’s a well-balanced battery for serious hobbyists who want both performance and reliability without paying premium-brand prices.
