Cut the throttle

Continuous current is shown in amps with one decimal, from 0 to 400, in steps of 1. The demo is 0. The footer says 0 means no limit, and that the flight controller lowers throttle to stay under the limit when one is set. It also says this needs a working current sensor. Without that sensor the limit has nothing to measure.

The picture is that rule and not the limiter's own loop. Draw starts at 40 A and continuous starts at 0, so the lamp says no limit and the throttle stays at 100 percent. Set continuous to 40 A and the same draw is still inside. Set the draw to 80 A and the picture cuts the throttle to half, 40 divided by 80. A draw that only equals the limit is still inside. The cut starts once the draw passes it.

Burst current uses the same 0 to 400 A range and also starts at 0. The hint says it is allowed for a short time above the continuous limit. While it is 0, Burst allowed for and Ramp down to continuous over are hidden. Those two are in seconds, from 0 to 300, in steps of 0.5, and both start at 0. The ramp hint says that time is the last part of the burst.

Continuous power and burst power are whole watts, from 0 to 4000, in steps of 10. Both start at 0, and 0 is no limit, the same as current. Burst power's time and ramp stay hidden while burst power is 0, and those times use the same 0 to 300 seconds.

You can set a current limit, a power limit, or both. The footer treats them as the limits the throttle is held under. A pack that sags in voltage can hit a watt limit before it hits an amp limit, and the other way around on a fresh pack. Leave a limit at 0 when you do not want that one applied.

Limiter tuning sits under the limits and is labelled for all battery profiles, not only the active one. P and I start at 100 and step by 10, from 0 to 10000. The P hint says it is how hard the throttle is cut on an overshoot. The output filter starts at 1.2 Hz, from 0 to 100, in steps of 0.1. The picture does not model those gains. It only shows the cut once the draw is past a continuous current you set.

The limits footer says the current and power values are saved in the active battery profile. The profile card is the row of profile numbers on the same Power tab. Switching is refused while armed. The line on that card says to disarm to switch battery profiles.

Each profile has its own cell count, cell voltages and capacity, plus idle, hover, cruise and failsafe throttle. With battery profile auto-switch on, the flight controller picks the profile whose cell count matches the pack when it is plugged in. The limiter P, I and filter are the exception marked for every profile.

A limit of 0 does not protect the pack. Set the continuous current to what the wires and the cells can hold, then save that profile. The Betaflight calibration page is a different scale, on a different firmware. Do not paste an INAV amp limit into a Betaflight vbat scale.

Open Power on INAV and find Power limits. The card is there when the board has the continuous current setting. Chrome or Edge connects over USB or Bluetooth. Android adds Wi-Fi. iPhone uses Bluetooth or Wi-Fi and has no USB host.

Confirm the current sensor agrees with a meter before you trust the cut. A sensor that reads low will let the pack past the number you typed. Props stay off while you only change the fields.
