Adding a second domestic battery......!

[fergycool]

Hello all,

I know the ideal situation is to site members of a battery bank right next to each other, but would 0.5m be a problem? Well that would be 0.5m total cable length between the pairs of terminals? I need to add a second battery and I just cannot get one next to the existing one? However, I can fit one perpendicular to it through a bulkhead.

Thanks!

Should be fine - especially if, instead of connecting both of the outgoing cables to one battery, you put the positive cable on one battery and the negative on the other. Connect both pairs of battery terminals together (+ to + and - to -) as normal as well. This arrangement evens out the voltage drop across the whole bank.

Thanks. ....and in a rare moment of thinking ahead, the +ve cable actually has sufficient slack to move it to the other battery. So making what you suggest very easy.

No problem just use a decent size cable. I added a 3 battery to a previous boat and mounted it across the engineroom to correct the list. Distance was about 2 metres.
