What kind of battery is used for 30A electricity? Analysis of hot topics and hot content across the entire network
Recently, the issue of battery selection for 30A ESCs (electronic speed regulators) has become the focus of discussion among many model aircraft and car enthusiasts. This article combines the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the battery types, performance comparisons and purchasing suggestions for 30A ESCs.
1. Basic requirements for 30A ESC
30A ESC is usually used for small and medium-sized drones, RC car models or boat models. The battery selection must meet the following conditions:
| parameters | Requirements scope |
|---|---|
| Voltage | 2S-4S (7.4V-14.8V) |
| Continuous discharge current | ≥30A |
| Peak current | ≥45A (instantaneous) |
2. Comparison of popular battery types
According to recent e-commerce platform sales and forum discussions, the following three types of batteries have received the most attention:
| Battery type | Representative model | Capacity range | C number (discharge rate) | Adaptation scene |
|---|---|---|---|---|
| Lithium Polymer (LiPo) | Tattu 3S 2200mAh | 1500-5000mAh | 25C-50C | Racing drones, car models |
| Li-ion | Molicel P42A | 2000-4000mAh | 20C-30C | Long endurance FPV drone |
| High voltage lithium battery (LiHV) | Gens Ace 4S 3000mAh | 1800-4000mAh | 30C-45C | High explosive car model |
3. Analysis of hot topics on the entire network
1.Battery safety discussion: The recent bulging incident of a certain brand of LiPo battery has attracted widespread attention. It is recommended to choose a battery with a protective plate.
2.Cost-effectiveness battle: Zhihu hot posts show that 60% of users believe that ZOP Power 3S battery has the highest cost performance among 30A ESCs.
3.new technology trends: The main test of UP at Station B shows that the temperature rise of graphene batteries is 15°C lower than that of traditional LiPo when continuously discharged at 30A.
4. Suggestions on purchasing
| Usage scenarios | Recommended battery | Things to note |
|---|---|---|
| racing drone | CNHL 4S 1500mAh 100C | Requires balance charger |
| Off-road car model | HRB 3S 5000mAh 50C | Pay attention to waterproofing |
| Entry level FPV | RDQ Series 3S 2200mAh | It is recommended to install a voltage alarm |
5. Latest test data reference
According to the latest actual measurement from the RC Groups forum (updated in 2023):
| Battery brand | 30A continuous discharge time | Voltage drop | surface temperature |
|---|---|---|---|
| Tattu R-Line | 4 minutes and 22 seconds | 0.8V | 48℃ |
| Turnigy Graphene | 5 minutes and 15 seconds | 0.6V | 42℃ |
Conclusion
When choosing a 30A ESC battery, discharge performance, weight and budget need to be considered comprehensively. Recent hot spots show that graphene batteries and high-voltage lithium batteries are becoming new trends, but traditional LiPo is still the mainstream choice. It is recommended to give priority to well-known brand batteries with XT60 interface when purchasing, and check the battery health status regularly.
