Pre-charge resistor size for 3 times 2x7A RoboClaw

[bmg]

Hi,

I am going to use 3 RoboClaws (2x7A) connected in parallel to 7.4 V LiPo source.

1. Is pre-charge resistor required/recommended in this scenario (7 VDC supplly)?
2. How do I choose the pre-charge resistor in such setup?

Kind regards

Pre-Charge is pointless at that voltage level. I dont recommenda pre-charge resistors until you reach 24v input voltage.
