At what voltage should I land my drone?
The 90% rule… You should land when you have used 90% of your battery capacity! At this point the battery should theoretically be at around 3.5V – 3.6V.
When should I land my LiPo battery?
Over-charging above 4.2V could be dangerous and eventually cause fire. However it’s advisable to stop discharging when it reaches 3.5V for battery health reasons. For example for a 3S Lipo, the max voltage is 12.6V, and you should land when the voltage reaches 10.5V (at 3.5V per cell).
What voltage should I set my LiPo alarm at?
3v/cell is the lowest resting voltage you should take a lipo to.
What does 4S battery mean?
Battery Voltage This is sometimes why you will hear people talk about a “4S” battery pack – it means that there are 4 cells in Series. So a four-cell (4S) pack is 14.8V, a three-cell (3S) pack is 11.1V, and so on. So the more voltage you have, the faster you’re going to go.
What happens if you overcharge a LiPo battery?
In a lithium-ion battery, overcharging can create unstable conditions inside the battery, increase pressure, and cause thermal runaway. Lithium-ion battery packs are required to have a protection circuit to prevent excessive pressure build-up and cut off the flow of ions when the temperature is too high.
What is LiPo sag?
LiPo Load Voltage & Voltage Sag This discrepancy (the difference between resting voltage and load voltage) is called “voltage sag”. Also note that the drop off point of load voltage happens a bit later on the 20C battery than the 45C battery.
What should my battery voltage be when I Land?
When you land, the voltage will come back up a little. However, for tiny whoops, because they use little 1S batteries, the voltage will sag more than bigger batteries. So it’s normal to land at 3.2V or even 3.1V per cell, and after some 10/15 minutes of resting it will come back to around 3.5V.
Is it OK to go below 3.7V per cell?
Most manufacturers recommend not discharging below 80% so your answer is any flying time that results in the battery being above 3.7V/cell after landing is OK. Here is a voltage chart vs remaining capacity. The % can vary by as much as 5% depending on the brand/age/condition of the battery.
What’s the proper Lipo voltage for a cell?
The common sense of lipo voltage as below: 1. A fully charged lipo voltage is 4.2V per cell (HV lipo can be charged to 4.35V). 2. A lipo cell battery should never be discharged below 3.0V. 3. The proper lipo storage voltage is 3.8V per cell.
How can I tell when my battery is ready to land?
The most common way of determining when to land is by checking battery voltage on the fly. Avoid discharging your LiPo voltage below 3.5V per cell! Note that when you are flying, because the battery is under load, the voltage will sag. And when you land, the voltage will come back up a little.
