These are the perfect setup for a RV. I have 3 of them. Can run days and days without running out of power. The app is great. The bms works good. Bigger than expected but I was mounting them inside anyway. I have yet to run one out of power but they hold strong all the time.

So far this 300AH battery has performed well. It’s been in continuous use since installing into a 2024 bumper pull RV. These new RVs have a 12 volt only refrigerator now. Turning the refrigerator off is not an option when living in the RV. A good battery is needed to make it thru the night, and this one can handle two or more days without charging it. I like the Bluetooth monitor app too, super easy to use. I am on the road all winter in this RV, with many days boondocking. It’s kept charged with a 400 watt solar system.

Very satisfied with this lithium phosphate battery. I installed it into my camper trailer with the battery box shown in the link below. It’s a solid box but weighs only 9lbs. It’s a bit pricey but well worth it. Keep in mind the box’s stated dimensions are external dimensions. The internal dimensions are smaller. However, the battery (16.3 x 8.46 x 10.24 inch) fits inside the box with some room to spare. If you don’t secure the battery it will slide and bounce around. To secure it, I cut some slots in the bottom of the box and used straps to prevent back and forth as well as up and down movements. Additionally I used rv leveling blocks to prevent the side to side movements. I drilled some drain holes in the bottom in case water gets in. The lid comes with a vent plug. Since this is not a lead acid battery that requires venting I sealed the holes up with caulking. That prevents rain water from getting in. There are still access ports around the edges of the box for wiring. So it’s not completely sealed by any means. However with the lid installed, rain water won’t be able to get in unless it’s super windy; hence the drain holes. The Bluetooth connected battery management system is awesome. I can now monitor the wattage each device consumes as they’re turned on. My camper comes with built-in lithium compatible power center as well as lithium compatible solar charger. So it was a straight forward install. I did purchase a separate ECO-Worthy 20A lithium battery charger which I used to charge the battery up before the install. It didn’t take long to charge the battery from 25% to 100%. When it finished charging, the built-in BMS reported the capacity at 303AH. Prior to purchasing the ECO-Worthy 20A charger I purchased the NOCO 5A smart charger which is supposedly compatible with lithium battery. However it was never able to charge the battery up. I’m assuming that it’s just too small for the the 300Ah battery. Lastly, it would be nice if the BMS is WiFi capable and it’s able to send you status notifications.

Battery does not charge correctly. BMS cuts it off at 13.9V and never displays "full". Their ap works well over bluetooth and indicates cell balance is a problem. No idea if it will deliver that 300ah. However the state of charge SOC is wildly inaccurate and Remaining AH also off. Both often show SCO 100% and only 200Ah remaining. the BMS went weird, it was being discharged and now shows 100% state of charge and its clearly not! before that it was down to 90% and I was not charging it. Zero stars! its a dud. Its an expensive failure. I will not buy again and likely return. however they now want me to ship it and I didn't keep the box for a 61 pound battery I can barely lift I have received a replacement. So two more stars for customer interface and timely handling. I will alter the rating again if it works correctly. EW and I worked to diagnose the problem and their offer of a replacmment and return shipping was accepted. The replacement arrived and after charging and testing works properly. Overall Eco-Worthy handled the problem well and the replacement working correctly. For their service rating is not 5 stars. If I should need another I would buy again.

We bought two of these eco-worthy 314 AH batteries. Absolutely love them and has made a huge improvement to our camper. They have an incredible charging capacity. Battery quality is extremely excellent. They weigh about the same as a 100 amp hour lead acid battery. Nice size for the high amp hours you get from them. As of right now they are performing exactly as they should. We have used them down to approximately 20% several times now and they work great and charge up nicely. We can use our 15K RV air conditioner for approximately 3-4 hours until we need to charge them. My only complaint is the incorrect volt reading on our Bluetooth screen. It's reading approximately 6 to 7 times what the actual voltage use/charge is. Checked it with a clamp voltmeter several times and get the same conclusion every time. As you can see in the pictures our Bluetooth claims we are using 4.6 volts but when checked with our clamp voltmeter were only using about .6 to .7 in that test. We contacted customer support about 2 weeks ago and have heard nothing. I followed up approximately one week ago to see if we could get a remedy for this and still have heard nothing. So in conclusion these are really nice batteries for the price but as far as customer service goes that part is horrible.

I completed the full charge today, battery appears to be very solid. The only drawback so far is the battery is taller then a regular size 24 battery and finding a toolbox for my TT has been a little difficult. Will update when I find a toolbox. All installed works great, the app is pretty basic IE charge leve, in/out amperage. I have not been able to determine if the battery discharges fully or if it is adjustable.

Well I bought 4 of these batteries to make up a house bank on my boat. and so far I am very disappointed. before I did anything I read both manual's that came with each battery. and even reading them it seemed odd it just kept saying for this feature push the button and for that feature just push the button anything you gotta do just push the button. well the only thing that the button seems to do is turn the lights on the meter on or off. other than that everything else that explains how to do any features is false as far as I can tell. even the discription on how to add each battery to the app did t work at all as it claimed it would . In fact all the qr codes that are supposed to help you to add each battery. they don't even work *scan in unrecognized* the QR codes in the manual don't work the stickers on each battery don't work. and the part that's really frustrating is I can't get any of them to even work. there all stuck in standby mode. so they are about as useful as 4 bricks to me that I just paid over $2,000 for. I'm not happy about this at all. so at least for now because they don't work at all I'm giving 1 star. not sure what else to do. *edit. I've contacted Eco-worthy and even though they claim they will respond withen 24 hours I have yet to hear from them. I've searched there website and the app or help or troubleshooting tips. nothing at all. In fact the only place I can even find mention of these batteries is on the website listed as for sale. I sure hope they make contact with me and are able to fix the issues of 4 batteries that don't work at all. and the manuals that aren't accurate about anything inside them..the status of these batteries hasn't changed nor once no matter what you do to them or how well you push the button. the Bluetooth seems to be non existent. even though it says it's on. but the fact of the matter is the Bluetooth logo has been on ever since I got the app to open. and no matter what you do the Bluetooth logo says it's always on. even though the battery is not? really?

So far so good, If you're using it in a RV just go ahead and get one of their chargers if your hooking them in series and disconnect your other charger that’s built into the panel.
