We currently have a house bank of three 115 amp hour, wet cell, deep cycle, 12volt batteries -wired to give us a total of 345 amp hours. We also have a separate dedicated start battery
. The house bank is on the port side of the engine
, and consists of three batteries wired end to end. The start battery
is on the starboard side, by itself. We are going cruising in November, and I have considered adding a fourth battery to the house bank. I will be replacing the current
three and buying
all new ones at one time, so there won't be any problem with mixing old and and new. Unfortunately, there is no room on the port side of the engine
to house the extra battery. There is room, however, next to the start battery on the starboard side. To add this additional battery, however, will require me to wire new battery cable to that additional battery. The positive cable connecting this new battery to the last battery in line on the current
house bank will be approximately 8 - 9 feet longer to get around the engine and to the battery location, as will the negative cable.
With the above in mind, is there any problem with wiring
the batteries this way? Is there any problem with having this length of cabling between battery #4 and the other three batteries? Is there any loss of power, any issue with charging
, or anything else I should know that would cause problems in adding this additional battery?
As always, thanks for the help. gchabs.
