How To Upgrade Your RV To Lithium Batteries?
You can upgrade your RV’s electrical system in some ways; adding lithium batteries is just one of them. Substituting lithium batteries with lead-acid ones has many advantages.
The case of complications regarding the technical aspects of batteries is often tricky for most individuals who aren’t professionally aligned to the field. However, National Battery Supply gets to be a part of it. It makes sure to guide their customers or people who need the practical information.
Lithium batteries give notable benefits to the user. For one thing, these can revolve around factors like faster charging, less energy usage, longer runtime and far smoother mobility.
Why Lithium Batteries Are Beneficial?
Additional reasons to evaluate the modification before we get into the details:
Increased Duration of Life
Lithium batteries are more practical and long-lasting than lead-acid ones since their lifespan is 10 times longer. Lithium batteries have the potential to last eight to ten years with good care. In contrast, conventional batteries can require replacement after a few years.
Less Downtime Between Power Outages
You may get greater mileage out of your recreational vehicle on a single charge using lithium batteries as opposed to the lengthy charging times with lead-acid batteries. Charging a lithium battery to full capacity usually only takes 3–4 hours, compared to 8–12 hours for lead-acid batteries.
Highly Effective and Powerful
There will be no degradation in performance while using the electrical equipment in your RV when you utilize lithium batteries, since their power output remains constant even as they drain. One distinguishing feature of lead-acid batteries is their quick power loss and inherent unpredictability.
Reliability and Security
The disadvantages of lead-acid batteries, such as smells, overheating and leaking, are less common with lithium batteries. Many systems that use lithium batteries have safety circuits built in to prevent injury.
How to Change the Batteries in Your RV to Lithium-Ions
Once we’ve covered why switching to lithium-ion batteries is a good idea, we’ll show you how to do it for your recreational vehicle.
Determine Your Power Requirements
Find out how much juice your recreational vehicle will require before you run out and get lithium batteries. Keep track of all the electronics and appliances in your house that require power. You may get a ballpark figure for your daily energy use here.
Get the amp-hour consumption estimate for your RV from a battery bank calculator or a professional.
Take into consideration the dimensions of your recreational vehicle, the appliances you wish to use, and the duration of your planned off-grid stay to determine the approximate number of batteries required.
Acquiring a Trustworthy Lithium Cryo Battery
Determine your power requirements before selecting a lithium battery. Do not forget these specifics:
The amp-hour is a popular way to measure the capacity of a battery. Recreational vehicles typically have a capacity range of 100Ah to 300Ah.
A BMS-equipped battery should be your priority. By preventing the battery from being over- or undercharged, the BMS increases its lifespan.
Old lead-acid batteries should then be disposed of.
The old lead-acid batteries may be removed once you have the lithium batteries. Be very careful to adhere strictly to all critical safety protocols:
- Remove any electrical devices that require a wall outlet.
- Prior to attending to the positive end, the negative end should be addressed.
Get the Batteries Ready for Supplying Lithium Power
After removing the old lithium batteries, the next step is to install new ones. The right way to do it is:
Never move the old and new batteries from their designated storage area. Be sure to keep them.
Be careful to connect the positive and negative terminals of the battery in that order when you connect it to the RV’s power system.
The right wire gauge for hooking up the RV’s batteries to the power system may be found in the handbook.
Simplify the Process of Making Payments
Make sure your inverter or converter can handle lithium batteries before you charge or use them.
Purchasing a system that tracks the battery’s temperature, charge level, and overall health is something to think about.
Conclusion
Even though it appears like a massive task, transferring to lithium cells is actually rather simple with the correct planning, tools and can-do attitude.
Get premium lithium batteries if you want your recreational vehicle’s charging capabilities to reach their maximum potential. If you want assistance with the seamless update of your gadget, consult an expert in installation or battery technology. In fact, you may find great recreational batteries on our website without delay.
