your cells are rated to 4A charge each, so 20A per pack in total. Meaning your battery regen values can safely be 10A on each ESC. Motor limit can be whatever you like (it will be more noticeable at lower speeds), I usually go with the same as my acceleration or a bit more for safety.
However, 20A I find to be a bit week (although it’s what I’m forced to run my week 2p board at). Many people on this forum say that it can safely be 2x as much as your cells are rated to, so if you feel the need, you can definitely raise the regen limits to 20A per ESC, and then remember to break sparingly (except in emergencies) to extend your cell lifetime. But before you do that, check to see what’s the max charging current your BMS can handle, because it will cut out if you give more than its rated for. (Which is really dangerous)
So I tried with dual idlers Andy still the belt slacked
I send it worth trying to trade those mounts as I want something with a larger amount of free rolling or I send it worth staying with them and just buying a new belt
It’s where you put your pulleys and idlers to where you want them to be, and then run a thread of string around the pulleys and through the idlers (where a belt would be), and when you get to where you started you make a mark with a pen (or just remember the spot). Then you use a ruler to measure the length of the string. That will tell you definitively what belt length you need.
