For example, the KiloVault HLX and CHLX batteries have Bluetooth to your Smartphone to see down to the cell level of each battery. Replacing traditional lead-acid with Lithium Ion. With flooded’s 2500 cycles versus lithium’s 5000 cycles, a well maintained flooded battery bank can last half as long as lithium. Yes – when they don’t contain cobalt. Proper ventilation mitigates this concern. A standard flooded lead acid battery can have about 2500 cycles at 25% DoD, A standard sealed lead acid battery can have about 1200 cycles at 25% DoD. The outgassing of the battery is normal, but requires owners to regularly check to see when the electrolyte level gets low from the outgassing. But step back and look at the bigger picture – taking into account everything we’ve covered so far – and you can see how lithium batteries can actually save you money, time, and hassle in the long run. However, while you can run your loads in freezing temperatures, you cannot charge a lithium battery in sub-freezing temperatures (below 32°F or 0°C). This may result in needing a battery bank that has a higher Ah capacity than you need to power your loads, just to handle the high current. Not all of them are. Why Replace Lead Acid Batteries with Lithium in a Boat or RV? As their names suggest, lead is used for making lead-acid batteries, while metal lithium is used for making lithium-ion batteries. Easy lithium drop-in replacement battery for lead acid battery. 3. But there’s yet another physical benefit of replacing lead acid batteries with lithium for RV and marine applications: Lithium batteries also don’t have the crazy weight from being made with lead! The chemistry used in Lithium Ion allows for more charge cycles. She’s been a sales rep, an instructor, and an all around solar evangelist, sharing her passion for solar around the world. If you currently have a V-belt, you may need to modify the engine for a serpentine belt before you can use the larger Balmar alternator. These are charged from my 24 volt solar system. A lithium battery saves on your electric bill, as it is up to 96% efficient and accepts both partial and rapid charging. Things to take into consideration are: The MLI Ultra series has an external safety relay (battery disconnect switch) and integrated battery monitoring, requiring proper installation and commissioning by a qualified installer. If you cycle your battery bank every day for a year, that’s 365 cycles. 1. If you have a high-current load in your system, or are charging it very quickly with a high current, such as your alternator or shore power, you need to consider the charge/discharge rate of the battery bank. Your Price: $45.00. Yes, you can replace your lead acid battery with a Lithium ion one. The following two tabs change content below. You would need to buy four AGM battery banks for $7200 – and spend the time shopping for and installing them – to match the lifetime of one lithium bank for $2600. | www.altEstore.com. I found that you can buy batteries for RC cars that match the power requirements. A lead acid battery’s capacity is rated at 80°F (26°C), but the colder it gets, the more capacity falls. Yes, you can replace the lead-acid battery with a lithium-Ion Phosphate for UPS. Do i need an external charger ? Smart Battery® 12V Lithium Battery - Drop in Replacement from Lead Acid, Gel or AGM Batteries. We see a lot of people continue to use a lead acid battery as the starter, with lithium used only for the house/service battery. Replace Lead Acid Batteries with Lithium for Marine and RVs – Why & How. They will often recommend a Bulk and Absorb rate of around 14V, with an Absorption time of as little as 2 minutes, significantly less than the standard for lead acid. Our lithium batteries are 99.1% efficient whereas lead acid batteries can be as little as 50 - 80% efficient. Let’s look at some cost examples when designing a battery bank for a 12V system that uses 1400Wh a day. There are a few ways to prevent this from happening. The Safari UT is a 12V 90AH Lithium Iron Phosphate battery designed as a drop-in replacement for typical lead-acid type batteries found in RVs. That’s a much longer lived battery bank with lithium batteries. 330 Codman Hill Rd, Boxborough, MA 01719 I’ll round up to 300Ah and use two KiloVault 1800 at $1300 each for a total of $2600. I’ll be removing my current battery bank consisting of 4 Interstate 6V golf cart type lead-acid batteries and replacing them with 3 of the new Safari UT batteries. Depth of Discharge, or DoD, is how much of your battery bank’s stored energy can actually be used without dramatically reducing its life. As a result, most quality solar charge controllers have a battery temperature sensor to report back to the charge controller. Higher Capacity. If you compare lithium batteries to lead acid batteries Ah to Ah, lithium batteries are more expensive. Its lead acid cousin will be approx 12.6-12.7v. Lithium-ion jump starters have nearly double the cycle life of lead-acid ones. If you intend to replace a lead acid battery with lithium for your starting battery, make sure the new lithium battery is rated to handle enough current to do so. replacing conventional Lead Acid (L/A) batteries with modern Lithium Ion based technology, is rapidly. altE Store That is a significantly smaller battery bank with lithium batteries. You will not need an external charger to charge your Lithium ion battery. But again, you have the advantages of the smaller, lighter, safer battery bank, the higher current capability, and minimal maintenance needed on the lithium. So let’s again compare a 518Ah 12V lead acid battery bank with the 300Ah 12V lithium bank. How it works. To get the most from the Lithium Ion batteries stay within the recommended operating conditions. With a Float voltage of just below 14V, you can maintain the charge without overcharging it. They monitor the temperature and will wind down to appropriate amperage if the alternator gets too hot. Obviously, abusing any type of battery can create a dangerous situation. We are still going to use two of the KiloVault HLX1800 for $2600, or I could use a single KiloVault HLX3600 300Ah 12V battery for the $2500. With lead acid batteries, we are used to seeing a rating of CCA (cold crank amps) to show how many amps can be used to start an engine in the cold weather. Likewise, if you are running a DC load like your bow thruster directly off the battery bank, you need it to maintain a high enough voltage for it to work when you really need it to work. When not at work, she’s either sailing or skiing, depending on the season, but odds are good she’s still talking about solar on the boat or on the slopes. Poor maintenance will also reduce battery life; Lithium ion battery: Lithium-ion batteries can be “fast” charged to 100% of capacity. Beyond 80%, the cycle count can drop dramatically. Victron SmartShunt – Monitors Batteries via Bluetooth. The substantial benefits that Lithium Ion technology offer over lead-acid technology means that using Lithium Ion batteries is becoming an ever more popular choice. Most batteries are rated at their C/20 rate, emptying the battery in 20 hours. You can replace the alternator with one designed for higher amperage charging and temperature control.

An automatic switch such as the Victron Energy Smart BatteryProtect can be configured via Bluetooth for excellent control of your system. Although the term ‘drop-in replacement’ is occasionally used in this case, it is actually never as simple as that. Your battery will last at least twice as long if you regularly discharge it 25% than if you regularly discharge it 50%. Its cycle life is more than 800 times, which is 2-4 times more than the SLA battery. Keep in mind that if you don’t have a sunny day to recharge your batteries after a day of use, the DoD will go down again the next day – so planning to use 25% per day will allow you to use less than the 50% maximum after two days of use. Lead acid batteries also perform best when charged at different rates based on temperature. 1(877) 878 -4060, Solar Power News & DIY Solar Tips > Batteries > Replace Lead Acid Batteries with Lithium for Marine and RVs – Why & How, Batteries, Off-Grid Solar, Renewable Energy, Westsail 32 with solar and wind Photo: Katie Payne. Lithium batteries do not have the CCA rating. Wiring three batteries in parallel would permit three times the rate, as it shares the current between the three, so 24A to 36A. So, if a lead-acid battery can last around 500 deep discharge cycles (or 80% depth of discharge cycles), a lithium battery can perform the same task upwards of 2,000 times, negating much of the upfront premium price paid for lithium batteries. The price gap between flooded lead acid and lithium is greater than with AGM. Due to lithium batteries’ voltage curve and ability to handle high current, loads like these will not cause the voltage to drop dramatically, eliminating the problem of voltage sag. Sealed lead acid batteries are among the oldest and cheapest battery technology, but Lithium-ion has become more prevalent due to its longevity. Victron Orion-TR Smart DC/DC Converter setup. That means a 100Ah lithium battery rated for 80% DoD can safely provide you with 80Ah without being harmed. A 12v lithium LiFePO4 battery fully charged to 100% will hold voltage around 13.3-13.4v. We are estimating that the lead-acid batteries will be replaced 3 times over a 10 year period, the lifespan of 1 lithium battery. A cycle is a cycle regardless of how deep the discharge is, but the depth of discharge directly affects how many cycles you can expect your battery to last. This 18.0Ah model can provide continuous current up to 18.0A with peaks of 30A. It can also be viewed via BlueTooth. This application note will summarize the key benefits of replacing Lead Acid batteries with Lithium. Are you ready to mobilize and go lithium? After observing battery voltage gauge on my car, I can see my lead acid battery operate voltage is from 11.8v to 14.8v. At first glance, the lithium bank costs more than the AGM bank. This means 50% of the power used to charge your golf cart is being lost due to resistance from the lead batteries. Explain how lithium batteries work in electric golf carts. Lithium batteries are also accused of being unsuitable for use in below-freezing temperatures. increasing. She’s been a sales rep, an instructor, and an all around solar evangelist, sharing her passion for solar around the world. Lithium ferrous phosphate (LFP or LiFePO4) chemistry has become the standard lithium battery for marine, RV, and general solar PV use because they have no thermal runaway issues. This runs the risk of acid spills if overfilled or overcharged. Both lead-acid and lithium ion batteries have surged in popularity over a couple of years. Watching more than just the voltage, but also how many amps go in and out of the battery bank and the temperature gives you a complete view of the health and state of charge of the entire bank. This requires you to be prepared with proper safety equipment including gloves, safety glasses, and baking soda to neutralize the acid if needed. This means a 100Ah lithium battery can handle 100A (or more) of charge/discharge current. If the car is designed using Lithium battery in mind from the first place, then it can be smaller (half the size, and can be smaller). Unlike lead acid, lithium batteries don’t have a cycle curve under 80% DoD. Although the batteries are set up to do this automatically and safely, taking proper care of your new batteries will prevent nuisances during use such as Lithium Ion batteries disengaging themselves (by a safety relay). With lithium ion battery systems get enhanced performance 90-99% effeciency with 4x life time and 4x faster recharge after discharge, a great diesel fuel saver where mobile telecom network sites are operating many hours on diesel generator that consumes a lot of diesel fuel.
