So when are my batteries on empty?

[aviator77]

Sorry if these are repeats of common questions. I'm new here and couldn't find the answer in the search.

I have a 2005 TXT and I just installed a voltage meter. My question is how low can I go before the cart is on empty? Will it stop at a certain voltage? What is the voltage for halfway to empty?

Also, what are the differences between using a voltage reducer for accessories and lights vs just hooking up to the first two batteries in a series?

Welcome to BGW ,what type of voltage meter did you install,the bar graph or the digital readout ?.I wouldn't put all my faith in those meters but use them as a guide.
You didn't say if your cart is 36 or 48V but you never want to go lower than 50% on those batteries.
On a 36 volt system 100% charge should be 38.20 volts and 50% is 36.31 volts.
On a 48 volt system 100% charge should be 50.93 volts and 50% is 48.41 volts.

48v is 50% so i tell my kid to head home when it reads 48.

Two of the batteries will be drawn more than if you used a reducer for the pack.

Welocome to the forum!

It is a digital readout and I have a 36v set up.
