I have a quattro 24v 3000 70 with the trickle charge cable connected to my starter battery bank, I recently had a co alarm go off in the engine room which I tracked to the starter batteries giving off hydrogen, they also felt warm to the touch, they haven't been used for a few months. I assumed the Quattro would manage the charge rather than keep charging when they don't need it and boil my batteries but that looks like what's been happening, so now i've disconnected the charge cable until I can find out what's going on, can anyone advise me please.
