Is the current most updated version. It is not tested because i changed the design to stuards V4.21.
Normally there should be everything OK because the known problems are already fixed at that design.
As soon as the new controller version is released by Stuard i will also order and test my new design.
Yeah, you need to change some parts with only the 67mm spacing. I would recommend to change all parts from 0806 to 0604 and also reduce the power resistors from 16 to only 8 for a 1.3A balancing current. Should be more than enough for 50Ah cells and if you are not cooling them with an extra heatsink they will reach 60°C very fast anyway.
