Rewiring my house bank and have a question about the size cables
Setup is six batteries
, 6V each wired series/parallel. The cables
to link the six individual batteries
are only 7" long. Since it's the house bank 90% of the time I'll be drawing no more that 5-10-15 amps but do have a 2000 W inverter
attached and have the system wired so if needed could use the house bank to start the engine
. Either of these could draw up to 150-200 amps at 12 V from the batteries.
According to tables and calculations for voltage drop and cable capacity, a 1 gauge wire would safely carry over 200 amps and drop less that 0.1V for 7"
or even for 21" if you add the drop for all the connectors. However, this doesn't take into account the distance from the battery
bank to the starter or inverter
So the question, will using a 1 gauge cable for linking the batteries be a problem? Yes I know I could use larger but the smaller cables are much more flexible and will be much easier to bend to the shape I need to fit the setup.
I will use 0 or 00 for the longer cables to the starter and the inverter.
