The Hoovo 2200 mAh 3S LiPo is a small but intriguing battery pack. Rated at 80C, it promises high performance for its size. In this test, I compare it against the Turnigy Graphene 2200 mAh 3S battery to see how it handles high-current loads. This comparison helps determine how accurate the advertised C rating is and how well the battery performs in real-world conditions.
What Makes It Unique
The Hoovo pack stands out due to its compact size and high advertised C rating. While similar packs often fall short under stress, this battery claims to maintain high current output. Additionally, its lightweight design makes it appealing for smaller RC models where weight is critical.
Internal Resistance and C Rating
I first measured the Hoovo’s internal resistance to estimate its real C rating. Using our Patreon LiPo calculator, the pack’s 2200 mAh capacity and 11.83 mΩ average internal resistance yielded a C rating of 15.5, far below the advertised 80C.
By comparison, the Turnigy Graphene showed an internal resistance of 4.3 mΩ, which confirms its ability to handle higher currents more efficiently. This initial test already suggested that the Hoovo might struggle under demanding loads.
Load Performance Test
The Hoovo pack reached voltage cutoff after delivering only 458 mAh, which is about 20% of its rated capacity. At the 3.5 V per-cell mark, the Hoovo barely registered output, while the Turnigy maintained stable voltage. Average cell wattage further highlighted the difference: the Hoovo produced 180 W per cell, whereas the Turnigy delivered 260 W per cell.
Practical Applications
The Hoovo pack is best suited for light RC models or applications where only moderate power is needed. Its small size and low weight make it a good option for small drones, micro boats, or lightweight cars. However, it is not ideal for high-speed runs or extended high-current use, as it cannot sustain the advertised performance under heavy loads.
Final Thoughts
The Hoovo 2200 mAh 3S LiPo demonstrates that advertised C ratings can be misleading. While it offers a compact design and moderate power for small applications, it falls short under high-current demand.
By contrast, the Turnigy Graphene proves more reliable, delivering higher usable capacity, stable voltage, and better overall energy efficiency. For anyone seeking consistent performance under load, the Turnigy remains the safer choice.
