Battery Mamba Monster question.
 

I have a doubt about the battery such as a battery of 5000mAh 4s 65 ~ 130C discharge would be too much for a mamba monster, or C battery is not matter anymore because the controller will pull a maximum of 120A.
Having more C in the battery it would save more issu bring a problem to the esc? or select only pulls what He needs.
Thank you all.

30c^
 

30c or more is good but be careful lots batteries over rate the c rating. what brand of battery are you geting? adding a cap bank is also a good way to protect esc

Common question, but you don't have to worry.

Assumption 1: A battery can have "too much" discharge current rating.

The battery will only deliver the current that the load requires. You could have a battery capable of providing 10 trillion amps of discharge current, but if the load is pulling 1 amp, the battery will only deliver 1 amp. Of course, that size battery will likely be fairly large and heavy. :smile:


Assumption 2: The controller will "pull" a maximum of 120A.

The controller is rated to be able to pass 120A continuously. But in reality, 120A continuously will heat up the ESC quite fast and drain a 5000mAh battery in 2.5 minutes flat. The ESC is actually is able to pass current bursts in the hundreds of amps very briefly. The ESC does not limit the current by any means - other than bursting into a ball of flame if current is too high for too long. That 120A figure is just a ballpark value to give you an idea of how to compare it against other ESCs.

Anyway, the battery voltage, motor, and the mechanical load placed on it is what determines how much current the ESC will have to handle. The controller doesn't pull the current, the motor does; the ESC just regulates (via your throttle finger) how much battery voltage is actually getting to the motor.

Thank you all. I was afraid that a battery with high discharge could ruin my esc but from what I understand the esc so will pull the battery needed.
