Same as mixing lead acid and agm but to a lesser degree. Yes, you certainly can. That means you shouldn't connect batteries together that aren't the same age or haven't been used in the same application since they were new, even if they are the exact same make and model. February 12 in Marine Electronics. The greater the difference in voltage, the higher the probability of battery failure. For some marine and RV applications that use a lot of batteries, it may make sense to isolate a larger bank of nine batteries into three smaller banks of three batteries, instead of connecting them all together. Bank 2: Three 100 AH LiFePO4 batteries in parallel. Mixing AGM and Lithium Batteries: Is it Safe and Effective? For the longer explanation on why this is a very bad idea, keep reading. Its NOT compatible. Marine lithium batteries in operation | Nordkyn Design, Free of Heavy Metals, New Battery Design Could Alleviate Environmental Concerns | IBM Research Blog. Check out our other blog postshere, contact us by chat onFacebookor by email atcontact@jypbatteries.com. BBug When you connect two or more batteries that don't charge and discharge at the same rate, one battery will probably end up overcharged and/or one battery will end up undercharged. Different types of batteries (flooded or AGM) also can have different charge/discharge characteristics. As batteries age (or get used), their charge/discharge profile changes. AGM and lead acid batteries can be mixed, but it's not recommended. Is it possible to connect a lithium battery to an AGM battery in series? We want to upgrade the house bank to lithium. This is critical. I already run the new style LiFePo4, by itself, for electronics only. So, can you mix AGM and lithium batteries? Love your videos!! There are four different chemical types of marine batteries for your boat: wet cell (flooded), gel cell, absorbed glass mat (AGM), which are all lead-acid batteries, and lithium. That doesn't mean the other functioning batteries should be discarded entirely, but they should not be used in an application that has batteries that differ in age, size or type. However, the cheapest solution would be to have a small light or other small load so the alternator would never be without a load. Your local shop where you buy your third party oil filter wont have a clue, and will tell you its compatible and your Yanmar dealer wont be able to tell you why or what the difference is. If worse comes to worse and one is on the water with a dead cranking battery, could you use the lithium to jump start with cables? If more please let me know. Let me think about it in how to solve that problem. It is not possible to mix the two types of batteries together, as they are two different types of chemistry. This is to guarantee that the BCDCs charge profile is appropriate for both batteries. The type you choose is based on your needs (engine starting versus deep cycle), the capacity and lifespan you are looking for and your budget. Combining an old lead acid battery with a more capable battery in series is kind of like combining an old mule with a stronger younger mule in a team. An equalization mode is available on most, if not all, lead acid chargers. However, you should never be connecting different battery sizes together in the same bank! With patented Spiralcell AGM Technology and unique six-pack design, OPTIMA (R) batteries offer advanced performance for strong, clean power that outperforms conventional batteries. Yep your 100% correct not mainstream not tested, and a risk. I use 2 Schottky diodes, one to the lithium battery and 1 to the Deep charging AGM. Why lithium-iron-phosphate? Let us know if you have any additional questions about wiring or want to purchase more batteries for your system. I'm rather looking forward to new technologies in batteries: Today, IBM Research is building on a long history of materials science innovation to unveil a new battery discovery. Wiper Blades for a 2015 Honda Accord: What Size Do You Need? Because my inverter draws 100 A - which is connected to and drawn from only the Odyssey battery. All the batteries were stamped Sep 2007. AGM batteries are more sensitive to overcharging, so if you're using a lead acid charger, it may not be able to properly charge the AGM battery. Second, the batteries do not have to be identical. This is the easiest, but offers no safety nets and may impact lifespan. If you have a 24V trolling motor, you can use 2 12V batteries in series or a single 24V battery. Choose a suitable model for the type of battery and the charge you need to produce. With a background in literature and creative writing, KC has a talent for crafting compelling characters and immersive worlds. Old house bank of AGM batteries. Additional resources still need to be added for this topic. That can be true even if the batteries are the same size. The connections on this type of battery bank go from positive to positive and negative to negative. But it totally depends on the voltage regulator on the alternator. Lithium house bank. Its delicate, and it needs a protective circuit to keep it running safely. Lithium batteries also have their strengths and weaknesses too. I have the agms that I can take out of series to get it running if I needed to now. Be the first to know about new collections and exclusive offers. Dual Purpose Deep Cycle Lithium Marine Trolling Battery Group 34 Replaces Optima 34M 800CCA. If one battery in a 24 volt system, run by AGM batteries ,were to die, what would be the pros and cons of putting a lithium in as a replacement. Your link has been automatically embedded. Also, if the LiFePO4 batteries ever reach low-voltage-cutoff, I won't have an abrupt loss of all power since the load will be shared by the Odyssey battery. We have a Centaur 12/100 charger currently charging all the batteries. Check out our, Amps, Volts, Watts: Differences Explained In Simple Terms. Weve got more answers! You cannot connect batteries of different amp-hours in series withgood results. We recommend this because lithium batteries charge faster than AGM. On our boat, we currently have AGM batteries for the house bank (3 ea), start battery (1), and the bow thruster (2). Can you shut off or change the BMS board? Mixing an old and new battery, even of the same type/model, will cause the system to 'average out' and reduce performancethat's why replacing both (all) batteries in a multi-battery system at the same time is recommended. Currently, it lists 56 different battery options. Dang expensive though and you have to be careful if you do a equalization charge on a AGM. The problem with lithium ion or phosphate batteries is the internal charge controller. You must log in or register to reply here. Im sorry to say the one they show as compatible for my 4JHTE (and your 3JH2E) is no where near it. If you want to go Lithium - just get a 24v lithium battery to replace both old AGMs. We strongly recommend you DO NOT attempt to mix battery sizes (amp-hours) and connect together. Yes, that's right: The lithium Yeti battery can be paired with lead-acid. Lead acid batteries are not as effective because they can have issues with vibration. Length (in): 12-13/16 Inch. lots of good info here. More heat is produced when the gadget overheats or the battery is overcharged. Speaking of pennies: Cost approx $1000 for two massive panels, including the split shipping and duty fees. Lithium ion is a new addition to the marine industry. Height (in): 9-3/8 Inch. AGM and lithium batteries are both popular options for a variety of applications, including renewable energy systems, recreational vehicles, and boats. The turn-on wire would be connected to the amplifier's remote wire. AGM stands for absorbed glass mat, which is one of the main physical differences between AGM batteries and traditional flooded lead-acid batteries used in cars. So Thank you all for the discussion, and input. Happy sailing off to Taiwan and Japan soon, so if you see a glow in the sky, I got wrong and you can say I told you so. If more power is needed, Goal Zero offers its Yeti Link Expansion Module that allows for the addition of lead-acid expansion batteries. With this understanding, its evident that as long as the right voltage limit is set for the lithium ion battery youre charging, leaving a lithium ion battery on the charger shouldnt be a problem. I jumped into upgrading my 10-year-old house AGM bank to lithiums. In addition to different battery types, there are also three different battery chemistries available: flooded lead acid, AGM (short for absorbed glass mat) and lithium iron phosphate (LiFePO4). Most lithiums are rated for deep-cycle only and the BMS prevents high-amp discharges of the type needed to start a motor. You cannot paste images directly. We recommend this because lithium batteries charge faster than AGM. Minn Kota recommends a group 27 size for deep cycle batteries, but consider the size of your boat's compartments before deciding. The way these two batteries check the status of charge is the most significant distinction between them. Current Visibility: Viewable by moderators and the original poster, https://community.victronenergy.com/questions/19981/mixing-lead-acid-and-lithium.html. So firstly some information: Step 2 - Choose the Appropriate Aftermarket Charger. The voltage is increased by connecting the batteries in series, but the total amp-hour capacity is not increased. All rights reserved. @Cassiopeia Here is a thread you may find of interest and possibly overlooked when you searched the forum first? longer than AGM and requires far less charging time to fill up. I am not in need of new batteries, yet. These two sites have a good discussion of building lithium-lead hybrid, Consider some Durocell AGMs, available at a reasonable, https://www.zwerfcat.nl/en/lithium-hybrid.html, Electrical Design For a Marine Lithium Battery Bank | | Nordkyn Design, Lithium, where to buy - VI's or Puerto Rico. If you are considering mixing these batteries, it is best to consult with a professional or refer to the manufacturers guidelines. Should I have one for each alternator? What are your options? If you have an AGM battery, use a multi-stage smart charger. Check out our website or give our sales and tech team a call at 855-292-2831. You can run your devices for twice as long as you dont have to charge the batteries if you have 2x the current reserve. A 100Ah lead-acid deep-cycle battery can power a fridge for 13.3 hours using 630kWh per year. A lot faster. Should I use DC to DC charger like the Victron Orion-Tr or a battery combiner like the Blue Seas IC-ACR? Rugged A lead-acid battery will fa il prematurely due to sulfation : If it operates in deficit mode during long periods of time (i. e. if the battery is rarely, or never at all, fully charged). ), Blue seas circuit wizard wire size calculator, Lithium battery from electric cars for boat use, LiFePo4, lithium iron phosphate, charging 3.2 volt cells. LIFEPO4 at up to 90% and both have different charging characteristics, I personally think it not worth the hassle and potential setup challenges with at least multiple BMS's etc. I am addingLithium house batteries. Solar panels. Underway, off shore power, the Odyssey battery terminal voltage rapidly drops to 12.8 volts, and the LiFePO4 batteries (Bank 2) pick up the entire load until a transition occurs at 12.8 volts, where the Odyssey battery begins to take up the load. Left there 10 years ago to go cruising, so family friends etc still there, thanks for yuor thoughts. It prevent the AGM to discharge into the Lithium batteries and the Lithium battery feeding the AGM. Here at Battle Born Batteries, we offer two different lithium battery sizes: our 100 Amp-Hour BB100 series and GC2 series, and the new 270 Amp-hour batteries. Mixing Battery Sizes: What Happens? On the other hand, lithium batteries require a more sophisticated charging system and can be more expensive to purchase initially. Read This Before Posting! In normal situations, I never intend to use the banks in "BOTH" in normal situations., We cruise from Annapolis to Maine each summer. Can you imagine all this happening if you were to make a simple mistake in your boat ??? Subscribe and Like our channel for more partnered videos! Camp 2x longer with 2 lithium batteries vs. 2 lead acid batteries. Because a lead acid power battery has a different ideal discharge level than a lithium battery, a lead acid power battery will simulate an exaggerated amount of discharge, which may damage the lithium battery.
