Using LiPo with L298N

Hi guys I need help with that. I'm going to use my LiPo with L298N. But I have few questions.

  1. shall I use 7.4v or 11.1v.
  2. Is that safe (I never use this batteries)
  3. Which port gives the energy. (This big 2 red-black ports or the little charging ports)
  4. How can I charge this batteries. I have LiPo battery charger but it noisy and I think like there is a problem.
  1. Whichever you need. The L298N can handle either so it depends on what motors etc you plan to drive.
  2. Lipos are safe provided you are reasonably careful with them
  3. If you mean which connector on the battery then I can't see your battery but it's probably the "big 2 red-black" connector(s)
  4. Lipos MUST be charged at the correct charging current with a proper Lipo charger. Doing anything else is not safe.

Since you've given no information about your charger and I obviously can't see or hear it I can't help with that.

my charger is https://www.amazon.com/Balance-Charger-SKYRC-Input-Battery/dp/B01I2W6EPM

and the noise like this : When you start to charge your laptop and a noise comes from the adapter.

The L298 is not a great choice for a battery powered motor driver. The driver itself drops 2 to 4 Volts (depends on current draw). At 1 Amp current and a drop of 2 Volts that is 2 Watts wasted as heat. You don't say what type of motor that you are driving, but Pololu has modern MOSFET output drivers for steppers and brushed motors that are much more efficient.

I'm going to drive my Plane's engine. It's from a drone. I dont know what is pololu and is it avaiable in Turkey. Plane is OK now . But I dont sure about it can fly. If I use "pololu" is it run faster ? And In the plastic case of engine it have a gear. It slows the propeller. How can I disconnect the gear from here ?

Other robotics supplied exist.

Then why a two-way H-bridge.
I assume you only need your motors turning one way to get the drone UP.

Just use one LOGIC LEVEL mosfet per motor, and control it with a PWM pin.
Match battery voltage to the voltage the motors need.
