What I don't understand is the need to go from 8 AWG to 1/0. I found a white paper here Trojan battery put out that shows the ampacity going from 55 with 8 AWG to 170 with 1/0. Do dual T-105's really increase the need that much? I've tried understanding this with Watt's law W=V*I or watts=volts*amps and can start to understand it if one wishes to connect a 2000W inverter but, if not, why does one still need such a thick gauge wire? I'm very new to all this but would like to understand.
If you only plan on camping at full service sites, there is/was no need to upgrade to the T-105 batteries. A regular Marine/RV battery would have handled the task with little or no effort.

The wire between your TT's charge controller and the battery is fine as it is. There is no reason to change it. The only place where you need to increase the size is if you are planning on installing an inverter. A 600 watt inverter does not need the 1/0 AWG wire. The only time you would want to install the 1/0 is if you are planning on a large output inverter.

Use the heavy wire between the two batteries and to get to where the original battery connections were if you are relocating them. You can use lighter gauge to the inverter and then just tie into the original trailer wiring. The manual for my Xantrex gave the required wire gauge to support it.

When using (2) 6 volt batteries can one put the fuse between the batteries? I was thinking this might be a good place to install the fuse block. I'm planning on a 1000 watt inverter and running 2 gage welding wire cables, the inverter suggests/use a 150 amp fuse. I was thinking between the neg. and pos. terminals, since their in series, since nothing else would be wired to them.

No, the fuse has to be between the loads and the positive battery terminal. If you put it between the (2) 6 volt batteries on the positive side you will still have 6 VDC going to the load from 1 battery, which will not be good for any of your electronics $$$. The ground side will still be active.

It's a series circuit - break it anywhere and there's no voltage to the load.

M&A is correct... I was thinking Parallel, although I would not install it in the battery box unless you coat all the terminations with a corrosive preventative spray. The battery gasses will have a field day with the metal parts.

I just thought it would be easier to check a blow fuse in the battery box then inside a storage compartment or in the utility space for the water pump. I would put some grease on the metal parts like light bulb grease to reduce the corrosion. I would also clean these when I check the water level of the batteries.

Thanks

Hello, Newbie here. Are these Lead Acid Flooded Cell type?

Yes they are. See the black bars in the middle that go to the round caps? Turn that to open up the battery and check the electrolyte level. Just don't use your finger..

Sure not using finger... haha~ So I can just refill water if the liquid level is lower than normal, right?





I got mine from a garage and it's re-conditioned. How can I tell what type they are? What are their AH? Is there somehow I can check? Thanks.
