Testing data
| 4~8S Input | 9-10S Input | 11-14S Input | 15~20S Input | |
| Output | Single BEC continuous output. After continuous running for 5 minutes, the board temperature stabilized at 80~90℃.
No Thermal shutdown @ Room Temperature 20℃. |

| 5.3v | 15A | 15A | 15A | 13A |
| 6.1V | 15A | 15A | 15A | 12A |
| 8.1V | 15A | 15A | 13A | 12A |
| 12.2V | 15A | 13A | 10A | 10A |
| Peak output current 22A.
Peak current usually makes sense for servos. Servos do not always run at continuous high loads. |
