Precautions for 48V Li-ion Battery Charging

  • Charge in strict accordance with standard time and procedures.
  • Lithium batteries are generally in a charged half-charged state when they leave the factory, and the battery must be fully charged for the first use.
  • Use the original charger, the original charger has strong supporting performance and a moderate charging rate.
  • Don’t often use it to charge when the Undervoltage protection circuit works. The concept of completely discharging the electricity and then recharging is incorrect. The greater the depth of discharge, the more times the battery is used at a loss of electricity, and the shorter the service life of the lithium battery.

Comparison of 48-volt lithium battery and lead-acid battery

Compared with a lead-acid battery, 48-volt lithium batteries has the following advantages: small size, lightweight, strong temperature adaptability, high charging-discharge efficiency, safety and stability, long service life, energy saving, and environmental protection. 48-volt lithium battery can also be divided into ternary lithium battery, iron phosphate lithium battery, and lithium titanate battery according to cathode material.

1 Weight energy density

Now, the energy density of lithium batteries is around 200~260wh/g, lead acid is 50~70wh/g, and the weight energy density of lithium batteries is 3~5 times that of lead acid, which means that under the same weight, the capacity of lithium batteries is higher than that of lead. Lead acid batteries are three to five times stronger, There, lithium batteries have an absolute advantage in energy storage.

2 Volume energy density

What Does "12V" Mean?

To find out what is the difference between 12v and 24v in the battery systems, we ought to understand the basic definition for each first. 12V tells us that the battery supplies 12 volts under a nominal load. The same principle holds for a 24V battery bank in that it provides 24 volts.12V LiFePo4 batteries are utilized in most vehicles as a result of the electrical parts like the starter, lighting, and ignition systems are designed to control on 12 volts.

The 12-volt rating of a battery is the nominal voltage and it should be slightly higher or lower reckoning on the state of charge and loads. We typically use 24V battery systems in larger trucks and buses because of the vehicles higher power needs and long cable runs. you’ll also look at 24V utilized in larger boats and a few RVs with elaborate solar systems. 

What Does “12V” Mean?

What is a 24V Battery?

One way to form a 24V system is to use a 24V battery. 24V LiFePo4 batteries are less common than their 12V counterpart and are tougher to come back by. 24V batteries are comparatively expensive.

However, they are doing take up no space than running more batteries in a series. So, if space could be a concern, a 24V battery is also a stronger selection for you.

12V System advantages

Most vehicles use 12V systems as parts used in vehicles are designed to control 12V. When it involves RVs, most appliances like recreational vehicle refrigerators and lighting also work on 12V. 12V systems only need a battery and work well for low-power applications and short wire runs.

12-volt systems are nice for their simplicity and most recreational vehicle appliances work with them. Smaller solar systems are also easy to attach to them.

24V System advantages

24V systems are helpful as a result you’ll use smaller diameter wire and cut back electrical phenomenon by twice. If using smaller diameter wires will cut back wiring prices and reduce the space needed to run wiring. This is often particularly necessary wherever long wire runs are needed.

But wait, however, are you able to run a smaller wire with more voltage?

You can run a wire 2x smaller than a constant 12V circuit. This is often due to the higher voltage needing less current to provide a similar power. Since we may be running less current or amps, we can use a smaller wire. This is often a similar reason power is transmitted on power lines at terribly high voltages. The wires are often many, smaller, and carry lots of additional power!

When building out larger portable solar systems victimization higher voltages like 24 volts or 48 volts is extremely helpful. This is often Geo Astro RVs set up with thousands of watts of solar.

In addition to smaller wires, 24-volt systems operate additional with efficiency in motors and inverters. Often, a similar solar charge controller operational on 24V vs 12V can handle doubly the solar input. 

When Shall We Use A 12V or 24V System?

Now that we’ve learned a bit regarding 12V vs 24V systems, we want to learn more after we ought to use one over the opposite.

When building a DC (direct current) battery system, its crucial to know your power necessities to run the appliances you would like. The energy that’s consumed by a tool is measured in watts. Once you recognize your electrical power demand, you’ll confirm what system is needed based on the difference between 12 and 24 volts.

If your necessities are below 3000W, you’ll typically get by with a 12V system.

Many suggest 24V systems once your power desires are higher than 3000W or generating 3000W of solar or more. If your power consumption is even higher, higher than 6000W, you’ll take pleasure in an excellent larger DC system and think about stepping up to 48V. 

24V DC advantages For solar

We found many DC MPPT solar charge controllers have higher voltage capabilities to handle higher panel volts. They, however, have a tough current limit.

When using a 55 amp rated charge controller on a 12V battery bank, you’ll use the controller with 700 watts of solar. If you use that very same charge controller on a 24V battery system, it will connect with 1400 watts of solar panels. This suggests that the quantity of star charge controllers is required. They’re going to also operate more with efficiency at 24 volts. 

Conclusions

It isnt perpetually a clear-cut call. There are several variables to think about once decisive that one is the most suitable option.

Now that we know well the difference between 12v and 24v, they’re not as daunting as we originally think them to be. Whether or not you finish up with a 12V or 24V system, you currently know the variations. You’ll assess your needs and create an informed call to Maxworld power. Welcome to your call any time!
