Am I wrong or does this topic perfectly matches with my thread about the MR30 and my dispute with ROFIS / Banggood's CS team?

FWIW, Imalent's DN70 boost driver can draw 11.5 amps from the battery and maintains turbo until cell's voltage is down 3.1V, i.e. until the LVP is being triggered. Comparing this to ROFIS' sh***y boost driver that's quite a difference.
