Hi I have read in some forums that you should not close stepdowns in parallel without certain safeguards. In my project I have a Raspberry Pi that controls servomotors. These pull so much that a 9A stepdown is not enough. Now I plan to connect several small stepdowns (XL 4015) in parallel to my LI ION battery block with BMS. Each stepdown then supplies 3 servomotors. I have a total of 18 servos, so 6 stepdowns. Is that possible without causing any damage or the like? I am very happy to receive an answer Kind regards Max

Just beware that you must connect all of them GND together. > that a 9A stepdown is not enough. If these are the usual 9 Chinese Ampere, then divide this value by 5 to get Real World Amperes.

That's about the outputs. In your case only the inputs are connected
which is fine.
