Yeah, two batteries will work fine.

When you're looking at the 4 batteries in the HET, the 2 negative terminals on the right side of both of the right 2 batteries are the ground. The 2 positive terminals on the left side of the left 2 batteries are the 24v positive. The remaining 4 posts in the middle across all batteries are all 12v positive. This can be kinda confusing until you get the hang of it, because you can read positive voltage from a negative terminal.

Basically, in any automotive series or series/parallel battery arrangement, there are 3 possible terminals - 24v positive, 12v positive, or ground. If they're set up the following way, once you identify the 24v positive and the ground terminals, everything else is 12v positive.

This should be about how the stock HET is setup -

And this is about what it should look like with only two batteries instead of four -

What batteries are you running when you only put 2 in?

Mine has two large truck batteries instead of the four. If I get a chance today I'll try to get down to the garage and pull them out to get a picture. It's been that way for a couple years with no issues and much more affordable.

Hey Dave do you think I can get a pic of your 2 batterie set up and what batteries you went with?

Just curious, is there a way to lock the cab on these trucks? I understand that a determined thief will get in no matter what but what has anyone done to make it difficult for unauthorized entry? Thanks in advance

Bracket on your step slides up for you to be able to pad lock it and it blocks the door from opening.

You can also use the steering lock bar.

Then you can also use a parking brake cover lock. There are several styles

Then you can always pull a tank drain valve out if you are going to let it sit so it won't build air pressure.

Thank you! That's something I'll have to make up for sure.

Absolutely!
And maybe you can post pictures - in case you learn something new when you build yours...
