Which Lithium System Is Best For You

Do you want Bluetooth monitoring?Some lithium batteries come with elaborate built-in Bluetooth monitoring systems that can show everything from temperature to state of charge. Other lithium batteries do not come with any form of Bluetooth monitoring but can be paired with external monitors. Bluetooth monitoring is rarely a necessity, but it can make troubleshooting easier. What kind of company do you want to buy from?Lithium batteries are a big investment and have the potential to outlast your rig. You may want to expand your system in the future, in which case you would need matching batteries. You may be worried about warranty replacements. You may be worried about obsolescence. You may want something that is the same brand as your other components in your system in case there is a problem and you dont want tech support to point the finger at the other guy. Does it fit the budget?A lithium battery is an investment. Perhaps your ideal lithium system ends up being $6,000 but you only have a budget for $2,000 of batteries. If so, let’s talk about AGM. An AGM battery is less expensive than a lithium battery because the material is expensive and hard to come by.

Tesla Acquires Hibar Systems

Theres no detail available about the acquisition other than Tesla listing Hibar Systems as a subsidiary in its official filings with the Canadian Federal lobby registration, as first reported by Canadas Electric Autonomy.

The manufacturing company wasnt on Teslas subsidiary list in July and now it appeared on it on October 2 meaning that the acquisition happened in the last 4 months.

Hibar has since gone dark, killed its website and replaced it with a single page as it is being taken over by Tesla.

According to an archive version of its website, the company specialized in building manufacturing equipment for different processes in battery manufacturing:

Among Hibars latest technology offerings are its advanced Automated Vacuum Filling Systems for Lithium-ion battery applications for use in Hybrid Electric Vehicles, computer notebooks and similar products.

More recently, it ventured into making a full high-speed Lithium-ion battery manufacturing system.

Last year, it was awarded $2 million CAD from the National Research Council of Canada Industrial Research Assistance Program to build the system in Richmond Hill, Ontario, Canada:

$2 million to support the development of a high-speed Lithium-ion battery manufacturing system to meet growing market demand for mass electric energy storage solutions.

Its unclear if this battery manufacturing system has been deployed yet, but they have been making battery cell manufacturing equipment for a long time.

Lifespan Beyond 5000 Cycles

Many see the price tag of lithium batteries and immediately walk away. However, one of the most important aspects to consider is how long they last. Typical lead-acid batteries can last anywhere from 200 to 900 charging cycles. Under ideal conditions with proper maintenance, this ends up being a few years at the most with daily solar charging.

Conversely, lithium batteries are known for lasting 5000+ charge cycles, translating to 10+ years of use. For example, Battle Born designs their batteries to last 3,000 5,000 cycles regardless of the depth of discharge and backs their batteries up with a 10-year warranty. This guarantees that 80 percent of the battery will still be available after 5,000 discharge cycles!

Lithium batteries may come with a hefty initial investment but last years longer. Not needing to replace lithium batteries as often makes them one of the most cost-effective options for building a battery bank.

Lithium Battery Charging Recommendations

• Alternator : Most alternators charge around 14.4 – 14.8V This will sufficiently charge a Smart Battery under normal circumstances

• Inverter Charger / Solar Controller : Most inverter chargers have a remote that can program the charging system to either lead acid, gel or agm batteries. They will typically have a custom setting as well. Simply set the custom 3 stage charging as follows:
• Zero Memory Charging : Smart Batteries are 99.1% efficient and have no memory. This allows you to drain the battery and re charge at any depth of discharge .

Popular Lithium Ion Solar Battery Brands

There are many lithium-ion solar batteries on the market. The most popular choice for residential energy storage is the Tesla Powerwall, a 13.5-kilowatt hour lithium ion battery that costs about $11,500, including installation costs.

The Tesla Powerwall is one of the cheapest lithium ion solar batteries, which is one of the reasons it is so popular.

The following table outlines some other popular lithium ion solar batteries on the market:

• Less maintenance

Higher depth of discharge

The DoD of a battery is the amount of the stored energy in the battery that has been used, as compared to the total capacity of the battery. Most batteries come with a recommended DoD in order to maintain the health of the battery.

Lithium-ion solar batteries are deep cycle batteries, so they have DoDs of around 95%. Many lead acid batteries only have a DoD of 50%. This means you can use more of the energy thats stored in a lithium-ion battery without having to charge it as often.

Long lifespan

Because lithium ion batteries have a high DoD and dont need to be charged and recharged as often, they have a long lifespan.

Most lithium-ion solar batteries have a minimum warrantied lifespan of around 10 years, or a cycle life of 10,000 cycles – whichever comes first. Lead acid batteries, on the other hand, only have warrantied lifespans of around 5 years.

Higher energy density

The energy density of a battery is how much power the battery can hold relative to the physical size of the battery.

Ology: Our System For Ranking The Best Solar Batteries

We spent hundreds of hours researching solar batteries, analyzing cycle efficiency, performance, product longevity, warranty and usable capacity data. We compared each metric to industry standards.

We analyzed customer reviews to gauge each batterys performance and contacted customer service to understand the buying and installation process. We also assessed each manufacturers reputation, dependability and contributions to the solar industry.

Once we gathered all relevant data, we used the following scoring system to grade each solar company on a 100-point scale. We then divided the points earned for each providers final score on a 5-point scale.

• Depth of discharge : Not all companies disclose depth of discharge information. We awarded the most points to companies with transparent DoD metrics above the industry standard of 80%.
• Round-trip efficiency : The standard round-trip efficiency for solar batteries is 80%. The higher the round-trip efficiency, the more points a company earned.
• Power capacity options : We awarded more points to modular batteries with multiple capacities available, allowing for maximum customization.
• Warranty length : The standard warranty for solar batteries is 10 years. We awarded more points to companies with the longest, most comprehensive warranties.
• End-of-warranty capacity : Most solar batteries have a minimum end-of-warranty capacity of 60%. The higher the end-of-warranty-capacity, the more points a company earned.

Best Times To Use Lithium

The best battery type for your solar system will depend on several factors, like what your system powers, if you are on or off-grid, and how often the system is used.

• Lithium-ion solar batteries are currently the best solar storage method for everyday residential use. The batteries are highly dense and store a considerable amount of energy without taking up much space.
• Although lithium-ion batteries come with a higher price tag, the technology works best for everyday residential use. It is maintenance-free and more cost-effective than other options in the long run.
• Lead-acid batteries cost less upfront but require regular maintenance to keep them running properly. If you are only using a solar battery as a small-scale emergency backup power storage, it might not be worth the upfront cost of a lithium-ion battery.
• Lead-acid batteries are popular for DIY or off-grid solar power systems that arent used regularly, like on a vacation cabin or an RV. Keep in mind that if you go that route, youll also need to purchase charge controllers as a battery management system .

Lithium Iron Phosphate Solar Storage Battery Bank

LifePO4 batteries are fairly new for solar use. My home originally used a 24volt bank of lead acid . These failed only after a year of use. This was a costly mistake. My replacement bank is LifePO4 25.6volt batteries as in the left photo. These I bought off Amazon for 241usd each. Each battery has built in BMS for under/over voltage protection, cell balancing and temperature safe guard. LifePO4 requires 2 stage charging. In my arrangement, a float voltage was allowed since a load is always drawn by an inverter.LifePO4 does not explode or catch fire like lithium cobalt . It does not have toxic chemicals and offers four times the power density at a third of the volume compared to lead acid. For these reasons I felt safe to have such batteries in my Home. Also the lifePO4 chemistry prefers partial charge and partial discharge. You will have no danger of undercharging these batteries compared to lead acid which will sulphate if undercharged. If you are serious about solar powering your home, definitely go with lifePO4. Also make your lighting led and use inverter type air conditioners. Be energy efficient and your cost will be much lower.

The Main Components Of A Solar Energy System

Before understanding the details of how your battery works, itâs a good idea to examine the different pieces that make up your entire solar power system. Each of these pieces serves a vital function in creating sustainable power for your home or cabin.

The most important piece youâll need for your system are the solar panels. These come in a wide range of shapes, styles, and varieties, such as polycrystalline and monocrystalline. Many homeowners prefer monocrystalline panels for their simplicity and cost-effective construction. Solar panels connect directly to a charge controller, which serves a valuable purpose in your solar power system. The primary function of the charge controller is to act as a go-between for your solar panels and other parts of your system. Charge controllers safely and effectively distribute solar energy collected by the panels, sending it to the battery in a way that doesnât overload it.

Another vital part of your system is the battery itself. The primary function of the battery in your home solar system is to store energy for when you need to use power during nighttime hours or when clouds or rain are obstructing the sun. Batteries may charge through your solar panels and charge controller, but as a backup, most solar power battery banks can charge with an AC adaptor or other similar charging device.

How Long Do Deep Cycle Batteries Last

The lifespan of a deep cycle battery varies by battery types. Normally, AGM batteries lasts about 4-7 years Gel batteries lasts about 2-5 years Flooded Lead Acid batteries lasts 4-8 years, and a high quality Lithium battery can last more than 10 years. The lifespan of a deep cycle battery also effected by battery cycles, maintenance, and the environment in which the battery is kept. For example, a Lead-acid batterys cycle life can range from 500 to 1200, and a lithium battery can range from 2000 to more than 5000. Besides, a battery kept in a hot environment will experience a shorter lifespan than that in a cooler environment. The lifespan of marine batteries, RV batteries and boat batteries also depends on its usage scenario.

What Are Lithium Solar Batteries

Lithium solar batteries are simply lithium batteries used in a solar power system. More specifically, most lithium solar batteries are deep-cycle lithium iron phosphate batteries, similar to the traditional lead-acid deep-cycle starting batteries found in cars.

LiFePO4 batteries use lithium salts to produce an incredibly efficient and long-lasting battery. Because these batteries are deep-cycle batteries, they are great for solar applications which experience irregular charging and discharging.
