GNB won't have any more 600mAh cells until the end of March so we got these 520mAh HV instead. They perform about the same as the 600mAh with a bit more pop for the first 30sec or so. The 1.5g wright savings over the 600mAh is nice and it makes the flight time on these about the same or just a few seconds less depending on how you fly. You still get 2-6min flight times.
Originally we had planned to go with the BT2 connector but upon further testing, we actually found that the XT30 connector offered a significant performance improvement over the BT2. Based on these tests, we would recommend keeping the BT2 for Whoop platforms or otherwise motors that are smaller than 1103 and 1S. For anything 1S that has higher amp draw or larger motors, we’d recommend XT30’s even though there’s a 1g handicap for using such an overkill connector. There is a company working on an alternative to the BT2 that should be better as well. They say that the connector is due out sometime in February if their timeline holds.
About voltage on 1S cells:
Traditionally, we don’t want to run any LiPo below 3.3v/cell under actual use (under load) in flight. The actual issue is overdrawing amps from the cell which can cause overheating and sharp drops in voltage. 1S is a little different because it’s relatively difficult to overdraw the current from such a small cell that has such low voltage to begin with. This is why Whoop flyers generally land at 2.9v under load. If you slowly discharge a LiPo, it does not damage it to drop it down to 3v/cell and that’s basically what we’re doing with these very low voltage and low overall wattage crafts. Because this 3” 1S platform is more capable than the majority of other 1S quads, we would recommend landing when you see 3.0v in your OSD.
- 1S HV 520mah
- HIGH voltage 3.0-4.35v
- Not recommended to run below 3.1v in flight
- XT30 connector on a ~17mm lead
