# Quick Answer: Is 12v Better Than 24v?

## What is the difference between 12v and 24v?

The difference is that both batteries have different voltages which means in a 12 V battery , for every coulomb of charge that flows from battery 12 joule of energy is being used.

Similarly, a 24V battery has 720,000C * 24V=17,280,000 W energy stored in it i.e.

twice of the energy stored in 12v battery..

## Why does the military use 24 volt?

The voltage that is used for Military radios happens to be 24 volts! We have a winner! According to the mililtary documents from the 1940s (and this should be correct!), the reason for the 24 volt electrical system was to ensure radio compatibility. Note the date on the attached Detroit Arsenal image.

## How long will a 24v trolling motor last?

This will give you maximum speed and power and is often necessary on a large boat, or in strong winds. Thus, if you operate your trolling motor at maximum speed, you will typically get about 2 hours of use from a fully charged pair of “average” batteries. Possibly 4 hours of use for the larger extra capacity batteries.

## Do they make a 24 volt trolling motor battery?

In fact, power is one of the biggest advantages to having a 24v motor and for all who like power; they will embrace the idea of 24 volts of power in their battery. Using a 24-volt battery means that you can use smaller wires and still get more power flowing through 24-volt trolling motor wiring.

## Can I use 24v on 12v?

12-volt lights are compatible with 24-volt systems – they use electricity and can be wired into the system. Light bulbs and light strips are designed to operate at slightly lower and slightly higher voltages.

## How does a 24 volt system work?

If one battery has its positive terminal connected to the negative terminal on the other, it is a 24 Volt system. Of course, of the two remaining terminals, the “free” negative terminal is grounded (connected to the chassis), and the “free” positive one is connected to the rest of the electrical system.

## Which is better 12 volt or 24 volt trolling motor?

A 12-volt trolling motor is the most inexpensive and easiest to run. … A 24- or 36-volt system will allow the angler to fish longer periods out on the water, as they draw lower amps while providing increased thrust for more power.

## Is 24v DC or AC?

There are a multitude of different options, but by and large the two most popular options are 24VDC (volts, direct current) and 120VAC (volts, alternating current). Both 24VDC and 120VAC powered devices are readily available and each have their advantages and drawbacks.

## How do you run a 12v off 24v?

Yes, you can tap off of one battery and get 12V. Thing to remember is to split the 12v load between the two batteries. If you run a wire from between the 2 batteries, use it as a ground, and use positive from the truck harness, you will get 12V.

## Are semi trucks 12v or 24v?

In the U.S., trucks today are 12 volt. In years past they would be 12/24 volt wired through a series/parallel switch to provide 24 volts for the starter and 12 volts for the rest of the system. Today they have one, two, three or four 12V batteries hooked in parallel to give high current for starting.

## What is the advantage of 24 volt or 12 volt?

Reduced fire risk. – Better input regulation. 0.5v line drop at 12v = 4.6% supply drop whereas 0.25 v line drop at 24v = 1.04% drop. – Better inverter efficiency and regulation.

## Which is faster 12v or 24v?

Cars with 12v batteries and motors are capable of speeds of up to 4mph, while 24 volt vehicles can travel up to 6mph, although this is only if they are fitted with a 24v motor. Many kids electric cars with 24v batteries use 12v motors, the extra power prolonging battery life.

## Is there a 24v battery?

24V batteries are definitely available. They are manufactured just like 12V batteries and are used in a range of applications. Many home inverter systems use 24V batteries.

## Are Diesels 12 or 24 volts?

Simple, most large diesel engines still have 24 volt starters. Cumins, Cat, International, and some John Deere engines, if you wish to jump at the starter, require 24 volts.

## Does a 24 volt trolling motor need 2 batteries?

24 Volt Systems (2 batteries): 1. Two 12-volt deep cycle batteries are required. 2. Make sure that the trolling motor is switched to the off position or speed selector set to “0”.
