How many volts is a 12S LiPo battery?

How many volts is a 12S LiPo battery?

44.4v
12S LiPo batteries run at 44.4v and come in a variety of capacities.

What is ESC for LiPo battery?

The number of Lithium Polymer cells in series in your battery pack is determined by the Minimum and Maximum voltages. The ESC measures the input voltage from the battery and equates it to a number of cells based on 4.2v/cell.

What size ESC should I use?

The ESC can be selected based on the voltage and the peak current rating of the motor. A simple rule is to choose an ESC with atleast 5A more capacity than the peak rating of the motor, since you may be powering servos, receiver and other accessories from the ESC.

How do I choose the right ESC?

Now, we will learn all these factors one by one,

  1. Current Rating. The first thing to consider when selecting an ESC is the current rating or ampere rating.
  2. Input Voltage Rating.
  3. Weight and Size.
  4. ESC Firmware.
  5. With or Without BEC.
  6. Connection of ESC with motor.
  7. ESC Protocols.
  8. ESC Processors.

Can I use any ESC with any motor?

Short answer is no. Not all brushless esc’s are compatible with all brushless motors.

How long can a LiPo stay fully charged?

Never leave your LiPo batteries sitting around on a full charge for more than 2-3 days. If by the 3rd day you realize you are not going to use your battery today, you need to discharge your battery down to 3.6v-3.8v per cell for safe storage until you are ready to use the battery again. 11.

What does 50C mean on a LiPo battery?

50 x Capacity
50C = 50 x Capacity (in Amps) Calculating the C-Rating of our example battery: 50 x 5 = 250A. The resulting number is the maximum sustained load you can safely put on the battery. Going higher than that will result in, at best, the degradation of the battery at a faster than normal pace.

Why do ESC burn out?

Current too high. Battery voltage too high. Not enough cooling.

How do you match a motor and ESC?

ESC’s are rated in amps and maximum voltage. Your motor has a Kv rating which approximates the no load speed for whatever voltage (i.e., rpm per volt) is attached to it. In order to know how “big” (amperage) your ESC needs to be, you need both the load and Kv for the motor.

How do I choose the right ESC for my motor?

The first thing to consider when selecting an ESC is the current rating or ampere rating. Motors draw current when they spin, if you draw more current than your ESC capacity then it will start to overheat and eventually damage.

Is it bad to store LiPo batteries fully charged?

Nor should LiPo batteries be stored at full charge, either. For the longest life of the batteries, LiPos should be stored at room temperature at 3.8V per cell.

How do you know your ESC is bad?

There are 3 phases in an ESC, each motor pad corresponds to a phase. If one of those phases is damaged, your motor will stutter (won’t spin up full speed but rather it just twitches). Usually it has to do with bad MOSFET – the 8-pin surface mount chips on the board.

Can an ESC burn up a motor?

YES. A Bad ESC can burn a motor and a Bad motor can damage an ESC and cause it to burn. For first power up and ANY Bench testing, setup, programming, Calibraing, etc ALWAYS use a Current Limiter to prevent escs and motors from burning.

Does ESC choice affect motor power?

The ESC doesn’t affect current or performance to any great degree. Having a higher amp-rated ESC simply means your ESC will be less stressed and run cooler!
