1 12volt to 2 six volts
I'm switching out the single 12volt battery that my Momentum 328G came with to two 6volt golf cart batteries. My question is: There are two 1/0 cables (positive and negative) coming into the 12volt battery. Do I need to use the same size cable to hook up in series? I also have the factory 300watt solar panels installed. Thanks for any help on this question.

I would make the cable with largest size cable that you can and make the cable as short as you can. You want to decrease the resistance as much as you can. Think of it as a pipe. You want to make the flow of electrons as easy as possible. Increasing the flow through a smaller diameter will increase resistance, generate heat and through reduce the effective capacity of your battery bank.
Hope that helps.

In a word....Yes. Any wiring smaller than the 1/0 will cause a higher resistance in the circuit. Make sure and buy the proper size crimp connectors and use a quality crimper to make the cable with the lugs on it. Using a larger cable than 1/0 will not hurt a thing, but it's unnecessary. Using a smaller gauge cable than 1/0 will affect current flow in the battery circuit.

Got mine at a auto parts store. 6"s with the ends on it. Works great

Maybe a silly question, but why would I replace a 12V deep cycle with (2) 6V batteries? Always looking for better battery performance, but not ready to pay up to Li prices

6-volt batteries are generally designed with heavier plates than a typical 12-volt battery. My 6-volt batteries are rated at 238 amp hours each. The 6-volt batteries generally last much longer than a 12-volt battery in my experience. That is a lot of capacity. Lithium batteries can be discharged a lot deeper than a lead acid battery but you pay for that performance. In the long run they may be cheaper than lead acid batteries.

Is there a good resource for learning about how to do a 12->dual 6 conversion?
EDIT: I've found a ton of information online, and looks like it's pretty straight forward. Just need to figure out a better battery tray setup.Last edited by Cjohnson; 05-26-2020 at 07:03 AM.

The battery box in my 327M is a vented model. Should I be concerned about using vented boxes as I move to dual 6volts?
