The HRB 2200 is a 2200 mAh 3S LiPo battery rated at 30C. I tested it against the Turnigy Graphene 2200 mAh 45C to see how it performs under typical loads. I look at internal resistance, calculated C rating and load performance to suggest practical applications for the pack.
What Makes It Unique
The HRB 2200 is surprisingly lightweight for its capacity and budget-friendly. Its compact 3S design makes it accessible for hobbyists seeking an affordable battery option. However, during testing, we discovered a critical issue: the packs arrived with uneven voltage between cells, requiring balancing before performance testing. This is uncommon and can impact real-world performance. I truly hope this was a once off but can not confirm.
Internal Resistance & C Rating
When I first connected the HRB batteries to the charger, I encountered a critical issue. The initial cell voltages were inconsistent, ranging from 3.13 V to 3.73 V. After confirming the pack was not properly balanced, I balanced it manually and ensured it reached maximum voltage before testing.
I measured internal resistance using our standard procedure. Both HRB packs averaged 5.25 mΩ, giving a calculated C rating of 23.3C. This corresponds to a maximum continuous current of roughly 51 A, slightly below the nominal 60–65 A load test range. While the label claims 30C, the measured value aligns closely with the actual performance, emphasizing the importance of independent testing.
Load Performance
Under a 60–65 A load, the HRB pack could not maintain full current, averaging 57 A. It delivered 1535 mAh, compared to 2051 mAh from the Turnigy Graphene. At 3.50 V per cell, HRB provided 173 mAh versus 205 mAh for Turnigy.
Voltage dropped from ~4.20 V to ~3.53 V initially, then stabilized around 3.32 V before cutoff, showing the HRB cannot sustain high loads for extended periods.
Practical Applications
The HRB 2200 is best suited for lower-load applications where full power is not required. It can be used in small RC vehicles or as a backup pack. Budget-conscious hobbyists may find it appealing for casual use, but high-demand scenarios like racing or extended high-current runs may exceed its capabilities.
Final Thoughts
The HRB 2200 is an affordable, compact 3S LiPo with a few caveats. Critical issues on arrival, like uneven cell voltages, require attention before use. Performance under load is lower than higher-rated batteries like Turnigy Graphene, but it remains a viable choice for low-current or casual applications. Its value lies in accessibility and price rather than maximum output.
