These are great batteries and I have purchased 5 of them for a home power backup system. They have been working great and I really like having the display on the battery to easily check status. I also use the Bluetooth app to watch the batteries from the house. I also like having the cycle counter so I can track how far I am into the warranty. These work so nicely that I even decided to buy a set of Temgot batteries for my boat. Give me that LiFePO4 baby!

We are very happy with our new lithium battery. It has Bluetooth capability, which helps to keep track of its levels. It also has an information lcd screen that we find very helpful. So far, it’s functioning very well.

This was my first lithium battery on a trailer. So far good. I mounted the 300AH battery on its side inside my Winnebago 1708 MicroMini trailer. This 64 pound lithium battery was replacing two 64 pound each or 128 punds of 100AH AGM batteries mounted on the tongue. The APP is very easy to use. Contrary to some reviews, the bluetooth works great when paired with my Samsung S24Ultra phone. It stays connected even when I am more than 30 feet from my trailer.

Replaced 2 lead-acid batteries in my RV with one of these. Easily saved 50lbs of weight, and this battery should have far longer lifespan. I especially like the screen on the battery which gives all the details about charging, draining, battery temp, and more. The Bluetooth app has worked every time for me too. Very happy with this battery so far.

So far these batteries have been absolutely solid! No complaints other than the android app needs improvement. I've emailed and left feedback on google play but it's still a bit buggy. The battery is 1/2 the weight of my lead acid and fits in the same box my old ones were in. The charge time and output have been fantastic. I've used them in extremely cold weather with 0 issues.

I removed the lead acid battery and connected this LiFePO4 battery into my travel trailer. In order to get it to charge fully, I also had to change out the WF-8735P to a WF-8740AD converter (converts incoming AC power to DC power to store in the battery). Just a side note: the WF-8740AD, which is advertised to auto detect the type of battery it's connected to, did not automatically switch over to LiFePO4 charging mode. I had to call the company (WFCO) and convince them to send me a "jumper" that plugs into their unit to get it to switch over to LiFePO4 charging mode. Of course, the company that makes the defective converter is not the company that makes this battery. The battery itself has performed very well so far, charging the trailer's fridge, lights, fan, and water pump. I get about two days worth of off-grid trailer power now, compared to only one day with the old lead acid battery. Another feature I like about this battery is its LED view screen. Now I can easily check the battery voltage, percent of charge, incoming current, outgoing current, and even the state of each of the four battery cells. Very convenient! I can't speak about the battery's self heating feature, because we haven't had anywhere near freezing weather here. Hopefully that will activate if I go somewhere cold. Overall, I'm pleased with this battery, and the price was right for a self-heating, LiFePO4 battery.
