How to power the APM with battery and without power module?

Hello, I wanna know how to power the apm with batterie without power module, please help

Look for a converter 2S/3S/4S, etc, to +5V (electronically not very different to a PM, though).

Thank you for your reply,
I have never use ardu pilot, when i connect the battery, nothing happened i don’t have power module also,
I don’t know where to find converter
Any other solution ?
Connect battery without module

A PM will simplify your life, giving you voltage and current measurements.

If for any reason you don’t want to use a PM, and don’t know where to find a converter, look for a BEC (battery eliminator circuit) at hobby shops, Aliexpress, Amazon…

Replay: PM’s, voltage converters and BEC’s are not electronically different (switching voltage converters).

After finding a BEC, how to install it to the apm board?
I find a lipo battery voltage tester in the box,
Is it interesting?

Do you have a complete video tuto?
I think it’s gonna help me a lot like I’m a beginner

Thx you, i find these params
Are they okay ?

I don’t know. That version of firmware for the APM Flight Controller hasn’t been current in 7 years. You won’t find many around who remember much about it as the parameters have vastly changed since then. That’s why is listed as Unsupported…

I found THR_MAX 1000 but the drone can’t take offAll motors are working

so should i use the latest version of mission planer?

I don’t know what to do

Describe the components on the craft and it’s weight with the battery:
Motors (size and kV)
Prop size
Battery power (3S, 4S, 6S)

Are the Motors in the right order and turning in the right direction?
