this may be psychosomatic but noticed some differences in using a normal xt90 and xt90s (anti-spark) connector as a loop key.
first, at full charge, when using a normal loop key, voltage reads about 0.4v higher.
also, and this is completely unscientific, board seems to accelerate harder without the anti-spark key.
i know there’s a resistor on the xt90s that prevents a spark, then as it’s pressed in further a complete connection is made. but does this resistor in the middle have an impact on overall current flow?
