Renogy 12V 200Ah Bluetooth Self-Heating Lithium LiFePO4 Deep Cycle Battery, 5000+Deep Cycles, dust-Proof IP67, Backup Power for RV, Cabin, and Marine Applications-Pro Series

Swapped these 100ah pro versions with my AGM 100ah's and so far so good. They come out to 105ah, with 2, i'm getting 210ah in my van. I also swapped out the factor solenoid for the LI BIM 225. I may upgrade later to a DC to DC but so far its working great. The bluetooth monitoring is great, and so far zero issues with the battery. They are heated and sit outside the van so thats essential.

This Renogy 12V 100Ah Smart Lithium Iron Phosphate Battery replaced a 100Ah lead acid battery in a portable solar generator project.Yes, this new Lithium Phosphate battery is about 6x more expensive than the lead acid battery;Yes, there is more run time (because you don't need to plan to 50% usage);Yes, the solar controller needed to be replaced to deal with the Lithium profile.The new Lithium battery is less than half the weight of the lead acid battery;Side terminal battery terminals were used to connect the existing cabling to the solar controller and DC power inverter.There's a lot more... the lead acid battery was great for learning; I'm upgrading a total of 3 portable solar generators with these Renogy 100Ah lithium batteries and one of the solar generators will end up with a mated pair of batteries.The "shelf switch" for the Lithium batteries is an interesting feature - once these solar generators are put into service, I really don't expect to turn them off unless service is needed - but there is already a battery isolation switch in place. We'll see how useful it is in the future.The multiple battery balancing feature looks neat, too - when I get that going, I'll update this post.I was concerned about the expense and so far, I am not disappointed in the capabilities and feature set.Yes, I would recommend this to anyone needing this set of functionality.My use case:Installed in a rolling tool case https://smile.amazon.com/Husky-Connect-Mobile-Tool-Black/dp/B07BLLXHZZare this Renogy 12V 100Ah Smart Lithium Iron Phosphate Battery,the solar controller https://smile.amazon.com/gp/product/B07DNVTJHDthe power inverter https://smile.amazon.com/gp/product/B0792LW2H7 (the 3000 watt rating is overkill for my needs - I don't ever plan to get "there". For "daily" use, the penny is on the far side of the property where it is expensive to run power, but there are a couple of LED "cafe light" strings installed. If needed, I can bring one or more of the solar generators into the house and power computer network, computers or refrigerator in case of commercial power outage - or take it camping.Each + cable from the flexible solar panels https://smile.amazon.com/gp/product/B079HJQBVWis fusedhttps://smile.amazon.com/gp/product/B00YG1DY20The Renogy bluetooth module is connected to the solar controllerhttps://smile.amazon.com/gp/product/B079K3LRJ9There is a multi-meter connected to the various appropriate placeshttps://smile.amazon.com/bayite-6-5-100V-Display-Multimeter-Voltmeter/dp/B013PKYILSThere is a circuit breaker https://smile.amazon.com/gp/product/B001PT7XBE between the Positive battery terminal and the power inverter positive terminal (also acts to isolate the battery when needed).Add various cables for the panels and wiring inside the rolling tool case + a few strategically placed 3 inch round vents (the power inverter can heat up) + 14 gauge and 2 AWG cables and connectors, this solar generator project taught me lots and the practical uses are a bonus. Plus, no liquid fuels needed, no fumes (carbon monoxide) and the genny is very quiet compared to a gas-powered generator. Some may say this is an expensive way to get power where needed, but the learning experience was worth the investment.

UPDATE: Batteries were exchanged and monitor stopped working again. RJ45 ports on one of the batteries full of water. The IP54 rating should mean that the batteries are splash proof. They are not. Mine are installed under the hood of a motorhome. Splashes occur.The idea of a "Smart Battery" with a tightly integrated monitor is a good one. However, there are a couple of design issues. Installed the batteries 9/20. I then gradually lost functionality until the monitor would not work anymore on 10/8. The pictures were taken on 10/12 and show corrosion on the contacts and cable. I first lost the ability to put the batteries into shelf or storage mode. Then the monitor only showed data for one of the two batteries and finally it showed zero-everything, including zero batteries. Renogy needs to go back to the drawing board. My batteries are mounted under the hood of my Class A motorhome.The communications ports are centrally placed, thus interfering with a central bracket to strap-down the batteries. In most cases a strap or bracket will go over the middle. The ports point up and don't seal with the connectors, allowing pins inside the ports to corrode. The ports, when not used, are covered by a single rubber flap. One port is used for a single battery installation and so the other is uncovered and open to the environment. In a group of batteries this is true for the last battery in the chain.The associated monitor is also first generation and nearly unreadable with the backlight on or off. More work is needed.I lost the use of the monitor due to the corroded ports and wonder if the ports offered an ingress point for water onto the circuitry underneath. I am currently working with the manufacturer. Probably owning to the fact that this is a fairly new product, phone support didn't really seem to understand the product.

PACKAGINGThese batteries came very well packaged.ENVIRONMENTThere are no Li Ion batteries that will like the conditions in an engine compartment. Engine compartments get too hot. Some engine compartments also don't protect the batteries from water. Don't be that guy that puts a Li Ion battery in an engine compartment, then complains.CHARGINGYou need to use a purpose built battery charger. Li Ion batteries have extremely low internal resistance compared to Lead acid. If you try to charge these directly from an alternator. One of two things will happen, 1) the BMS will terminate the charge due to over current or 2) you will overheat your alternator from over current. E.g. If you have a 300 Amp alternator and only one battery the first scenario will occur. If you have a 300 Amp alternator and four batteries the second scenario will occur.SHELF MODEIf you want to put a parallel bank into shelf mode without disconnecting them, they must all be connected with ethernet cables. They also must all have one of the more recent firmware versions. When these batteries first came out the firmware did not allow parallel connected batteries to be put in shelf mode. Renogy sells a cable for updating the firmware.Power cableshttps://www.amazon.com/dp/B01F4GHYD0https://www.amazon.com/dp/B01F4GI0UGEthernet Cableshttps://www.amazon.com/gp/product/B0721RFHT8
