set up in car with blind plug

PS: how can I seal the cell, when I fill it, water pours out between the upper and lower 5″ hemisphere. Do you suggset to use e.g. silicon all around the cell’s equator?

Hi again Moshe,

sorry, maybe I asked my questions too fast. I watched the car installation video again and heard and read about seal with goop around the circumference. I try it and let you know…

all the best
