A friend of mine, another installer who does quite a bit of bow thruster work, insists on placing an additional battery
, in parallel, near the thruster and windlass
. His belief is that the surface charge of the battery
is more available for the short duration of need, and the recharging, with the 4/0 cable then is sufficient. I tend to keep all the batteries in a bank together, but on reflection, that may not be necessary. I'll leave it to the electrical
engineers to argue the merits of that. The legs from positive and negative posts are unequal, but the juice is the same.
