I have 150W PMDC motors which run on 24V. I connected two lead acid batteries of 12V and 7.5AHr in series to drive them. But the problem is that after running the motors for about 5mins, voltage of one battery drops to 9V when motor is rotating and it again shows 12V(its fully charged voltage) when motor is stopped. Every time the same battery shows the problem.What could be the problem?
