How to Wire a Golf Cart Batteries: The Ultimate Guide?

One of the best things about golf carts is electric and environmentally friendly. Vehicles that run on gas produce harmful toxins that negatively affect people and the planet.

Electric vehicles, like golf carts, do not produce any emissions, making them a more responsible choice. This is especially important today as concerns over climate change become more pressing.

To make your golf cart even more environmentally friendly, you can wire its batteries yourself. This guide will show you How To Wire Golf Cart Batteries in simple ways.

Necessary Materials For Wiring a Golf Cart Batteries

To wire a golf cart batteries, you will need the following materials:

  • Battery clamps
  • Six or 12-volt battery
  • 1 or 2 gauge wire
  • Wire cutters
  • Wire strippers
  • Soldering iron
  • SolderTools
  • Wire cutters or side cutters
  • Needle nose pliers
  • Channel locks
  • 10mm wrench
  • Screwdriver
  • Socket set (10, 12, 13, 14, 15, 16, 17, 18, 19, 21, 22) mm
  • Ruler or measuring tape
  • Tape measure or ruler
  • Pencil

 Types of Golf Cart Batteries

There are four main types of golf cart batteries-

  • Lead-acid Batteries
  • Gel Batteries
  • AGM Batteries
  • Lithium-ion Batteries

Lead-acid batteries are the most common type. They are inexpensive and last a long time. However, they are also the heaviest and least environmentally friendly option.

Gel batteries are a newer type of battery that is becoming more popular. They are lighter than lead-acid batteries and have a longer lifespan. However, they are more expensive than lead-acid batteries.

AGM batteries are also newer battery that is becoming more popular.

Lithium-ion batteries are the lightest and most durable type,  But they cost more than lead-acid batteries.

How to Wire a Golf Cart Battery Bank Step By Step

Before wiring a golf cart battery bank, you need to know a few things.

First, the total voltage of the battery bank should not exceed the voltage rating of the charger.

Second, you should wire the battery bank in parallel (positive to positive, negative to negative).

This will increase the current rating and keep the voltage the same.

Wiring a golf cart battery bank is a relatively simple process, but it is essential to take your time and ensure everything is done correctly.

The process of wiring golf cart batteries is not complicated. It is just that it requires some patience and attention to detail.

There are many ways to wire golf cart batteries, which can be not very clear. If you’re thinking of doing the same, here are a few simple steps to help you get started:

Step 1: Disconnect the Battery

The first thing you need to do is disconnect the battery from the cart’s frame. This will allow you to get at the terminals and cables located at the bottom of the battery box.

Step 2: Determine the Battery Type

There are two types of golf cart batteries, deep cycle and starting. The deep process is used for powering equipment while beginning to create an engine.

Step 3: Insulation Battery Terminals

Next, remove the insulation from both ends of each cable using a wire cutter or pliers. You will also need to remove any rubber insulation on top of the terminals.

Then, attach one end of each cable to its corresponding terminal with a bolt and washer, then tighten it with a wrench or socket wrench (though this may be difficult if you have small hands).

Step 4: Connecting Wires

Connect wires from one battery to another until all of the batteries are connected in a series of loops. Once the flurry of cables is completed, we connect one end of the wire to the positive terminal and allow it to protrude from the top.

Connect a bit more than half of another wire to the negative terminal on each battery. Do not let these wires come near each other, or else they will short out and create a spark.

How to Wire a Golf Cart with a 36-Volt Battery

Golf carts typically run on powerful electric motors powered by multiple batteries connected in series or parallel depending on the application and voltage required.

Six 6-volt batteries powering a golf cart system produce 36 volts. Golf cart batteries can last a long time with proper care. Installing new batteries or removing old ones requires knowledge of the correct wiring order.

Step: 1st

You must unlock the golf cart seat clasps to access the battery carriage. If you haven’t installed the batteries in the golf cart, arrange them in two rows, one top, and one bottom. Remove the filler caps and fill each cell to the upper mark with distilled water. If you have access to a golf cart battery charger, fully charge each battery.

Step: 2nd

Clean the battery tops and terminals with water and baking soda. Rinse and dry the lids. Wire-brush the battery posts with a battery cleaner tool to remove corrosion. Using a piece of chalk, number the two rows of batteries from one to six, starting with the upper left battery.

Step: 3rd

Suppose your system lacks battery wiring; layout enough battery cable to cut five equal lengths of about eight inches. Cut each length with wire cutters, then use wire strippers to remove about 1/2 inch of insulation from each end. Replace the cable connectors and tighten the crimp shackles with a socket. Ten cable connectors on five short cables.

Step: 4th 

Place the primary motor cable wire over the positive post of battery #1. Using a socket, tighten the connector. Connect the negative pole of battery 1 to the positive post of battery 2 with a short cable and a socket. Connect the negative post of battery 2 to the positive post of battery 3. Socket both connectors.

Step: 5th

Set up a short cable from battery 3’s negative post to battery 6’s positive pole, the next battery down in the second row. Socket both connectors. Connect a line from the unfavourable position of battery No. 6 to the positive post of battery No. 5.

Step: 6th

Socket both connectors. Reconnect the negative post of battery No. 5 to the favourable position of battery No. 4 with a socket.

Connect the primary engine ground wire to the negative post of battery #4. This completes the series connection of the batteries. Test the vehicle while seated.

The Benefit of Wire a Golf Cart Batteries

The Benefit of Wire a Golf Cart Batteries

There are many benefits to wiring your golf cart batteries. Doing so will give you a faster charge time, ensure even charging and discharging, and extend the life of your batteries.

When you wire your batteries, you create a parallel circuit. This means that all of the batteries will share the load equally. If one battery is weaker than the others, it will not be overworked and last longer.

Wiring your batteries also allow for a faster charge time. When all batteries are connected in parallel, they act as one large battery.

Tips and Tricks Wire a Golf Cart Batteries

Tips and Tricks Wire a Golf Cart Batteries

Batteries When it comes to golf cart batteries, there are a few essential tips and tricks to keep in mind.

  • First and foremost, you need to know the voltage of your battery. You can find this on the label on the battery itself.
  • You also need to know the amp hours (Ah) rating. This is usually listed in the owner’s manual or on the battery label.
  • It is essential to use a golf cart battery charger compatible with your batteries. Be sure to use the correct charging voltage for your batteries.
  • Overcharging or undercharging your batteries can damage them and shorten their lifespan.

Last Thought

In conclusion, golf cart batteries should be wired in series to increase voltage and in parallel to increase amperage. By following these simple steps, you can ensure that your golf cart batteries are well-wired and provide you with years of service.

Then when wiring your golf cart batteries, you must take your time and do it properly. Failing to do so may damage your cart or even personal injury.
