is anyone else running sideways mounted agm
2 L16 batteries mounted on their side. in series in 12v.
just killed the 2nd pair in 12 months. (both lasted about 6 months)
one flips polarity under load so the cell is f*cked internally. same as last time.
first one I took as a unlucky battery
defect. but now 2nd set on same boat 6 months later does the same thing.
I'm thinking the agm
claim of mounting any way is not true in real life use...
I've installed 50+ of this brand of agm L16s without issues. but this is the only ones on their sides.
