Problem with mgm 16018 under acceleration

[Serum]

Hi Munarin;

My best guess is the batteries;

Under load the voltage drops badly. that 7.234V you measured is in the most ideal situation (unloaded). I can imagine a 7.234V pack would drop way bellow 3.3V per cell under load. A fully charged lipo pack measures 8.4V on 2S. I would say the 7.234V is a rather empty pack.

so either the packs are not up the task, or the cells are not fully charged.
