Best options to go from 6 batteries to 4 12v batteries?

What's your 36v set up, motor/solenoid/controller/etc?

Thanks

I have the AMD Advanced Golf Cart Motor ES1-4002 (7122) motor, MZJ-400A solenoid, SR48500 controller, and SW202 reversing contactor.

Using a typical 36V battery pack as a baseline and since we'll be comparing different voltage battery packs. I'll use Watt-Hours (AH x V = WH)

The typical 36V pack is made up of six 6V - 225AH batteries and has 8100WH. (36 x 225 = 8100)

The typical 48V pack is made up of six 8V - 170AH batteries and has 8160WH. (48 x 170 = 8160)

In other words, those two packs have roughly the same range and lifespan.

A typical 12V deep cycle battery has 150AH of storage, so a 36V pack using 12V batteries has 5400WH (33.3% less than normal range and lifespan) and a 48V pack using 12V batteries has 7200WH (11.8% less than normal range and lifespan).

Making a decision can be easy, but living with the consequences often isn't.

Great information! Thanks for taking the time to share that. For me, the cart doesn't get much use so AHs aren't a huge deal, but it would be good to know for a prospective buyer. I mostly use the cart for the stereo when I'm outside working on projects or to take the kids around the block a few times.

The stereo is a bazooka party bar and a bazooka 10" subwoofer.
