DO NOT BUY THESE BATTERIES! They will work fine a couple times then every time you use them they will lose run time until finally one drops out in a couple hours only running 20A, I used these 36v with trolling motor 3batteries @ 100ah should run about 15 hours not 2 hours and one is completely dead. Don't be fooled! And customer support is garbage they want you to pay shipping back to them then they will send you new ones.

I have so far been very satisfied with this battery, and the app is extremely helpful. The app doesn't just let you see the current charge just you can also keep track of what uses how much power. It's bigger than 2 regular lead acid battery's so I had to install this battery under my couch, but that hasn't been an issue

I bought 3 of these to put in parallel to serve as the house battery for my 42' cabin cruiser. They replaced two six volt FLA batteries which were supposed to be deep cycle. The boat can sit at my back dock for months at a time and I have already gone through 2 sets of the 6 volt 235AH golf cart type batteries which need to be looked after carefully so that they don't go bad due to failure to add water to the cells or due to not charging them properly. Also, there is no way you can take 235 AH out of them per charging cycle. More like 100AH or else you risk damage. I have found that they are just fragile.Since the battery box was big enough to hold three of the LPFMAX Smart 12 V 100AH batteries, I upgraded from 100AH of real capacity to more like 210AH of real capacity assuming 80% DOD and only charging to 90% full. My charger is 150A so I never charge at more than 0.5 Capacity which I think is very safe. I could never even think of charging those Flooded Lead Acid cells at this rate!The ability to take data directly from each of the 3 battery units is what sold me on this product and I was not disappointed. The app is kind of a piece of S--- but I plan to write my own Windows software to communicate with the BMS'. So far I have only used the batteries for a single trip and they performed well. Having the ability to see how they are charging or discharging is SO important when it comes to optimizing your system. Until recently, LFE battery makers they were very proud of their bluetooth version batteries. I was happy to get 3 of these for $200 each + tax and free shipping. I thought it was a better deal than going with FLA again and I am convinced these will last for years to come.

We bought two of these when we upgraded our 2005 RV to solar. We are pleased with them so far. They are doing great and were the best price for similar products. Very happy with our purchase and so far would recommend. We've had them installed for about a month and they have been doing the job well as I've been out in the trailer completing the rest of the remodel, running power tools, all the lights and furnace on, etc.

The battery arrived quickly within only a couple days , arrived with 51% charge I fully charged and let it rest for 72 hours with initial resting voltage of 13.4 it all seems good I’m happy with the Bluetooth function , it’s nice not have to buy a separate piece of monitoring equipment , this battery is much less expensive than other ones with the same features plan on getting two more in the future .

This is a awesome deal. I love the Bluetooth connection. It is super easy to connect and a lot if information is provided. I don't have testing tools to do a discharge test, but I'm guessing it will meet specs. This also has cold charging protection and built in heaters. I may never need them, but if I do, it's nice to know they are there.

I recently purchased three of these lithium batteries for my RV and, so far, I'm very pleased. I was also pleased with the response of the company when one of the batteries was received with a crack in the outer casing (clearly some kind of freight or handling damage despite very good packaging). The Smart battery features works wonderfully and my expectation is that the self-heating function will also. Overall, I couldn't be happier with the product, especially at this exceptional price.
