LiTime 12V 100Ah Self-Heating LiFePO4 Lithium Battery with 100A BMS Low Temperature Protection, 1280W Load Power with 4000+ cycles and 10-Year Lifetime Perfect for RV Solar System Home Energy Storage

I installed these yesterday in a Forest River Class C motorhome and have been testing them, so far I am very pleased. I have been in contact with LI Time several times now (emails only, no voice contact is possible). Their responses to my questions are thorough, accurate and VERY prompt. Most likely these are Chinese folks that are responding, but if so their English writing is perfect. If you want, you could test them before you buy and ask any questions you might have and see the quality and promptness of their responses. You will be impressed. The product manuals, packaging, speed of delivery, and customer service, are all excellent.Also, there are youtube videos out there where they rigorously test and take apart these batteries and they are highly recommend by the non-affiliated test people. They report on the excellent design and internal quality so I recommend you seek out and view those videos before you buy.Note if you're installing these in a Forest River Class C motorhome you'll probably have to make the battery box (located under the entry stairs) opening slightly larger as theses batteries are 1/4" longer than a 27M-sized lead acid battery. I got them installed, but barely without making any mods to the battery box. My advice is to enlarge the battery box first. If you don't enlarge the box you'll never get these batteries out of there if needed.For the Forest River and any newer RV, you'll also have to change out your Battery Isolation Manager (BIM) from a model # 160 to BIM 225 to accommodate the new Lithium batteries. The BIM 225 is sold on Amazon. This install is easily done.

Was hoping the lithium phosphate battery would be a major upgrade for our camper and solar system. We paid extra for the self heating function. We live in Idaho and camp frequently when the temps are below 40 degrees. If you go below 40 degrees, the battery turns itself off to protect itself and goes into self heat mode until it reaches 50 degrees. So to avoid that, we have to run our heater constantly which uses battery and propane. So, it's a catch 22, not a great fit for our situation. I also think there is a malfunction in the BMS because it frequently turns off and then back on when taking a solar charge and we are running something like the water pump. It's very annoying. I am still trying to return the battery as it says it has a 5 year warranty, but keep getting the run around.

Bought this battery for a DIY solar for a shed. Supposedly, the self-heating feature helps it keep it charging in low temps. Not what happened in my case. As the light hours shortened in November and the temperature dropped, it stopped charging, or at least it was mostly involved in self-heating (while it does that, it does not charge). Not sure what exactly was the reason but in less than a week the system went completely dead with zero charge left, under very low usage. I used to have a simple sealed AGM battery and a smaller solar panel and it worked fine for months, even in winter. Now, with a 2x bigger panel and supposedly a much more advanced battery and the controller, the whole thing went "caput" in a week. Returned the battery. Not sure about all these battery control systems if they truly add value. Giving 3 stars for their responsive customer service, that took the battery back with no issue.

Such a good battery. Works in extremely low temps. I used it at 12°F and it worked great! I have the version with a heater built in. I'd buy it again and again.

So far this battery is performing well. It was promptly shipped and packaged extremely well. Also included more information about the battery than one would expect. Highly recommended.

Battery appears to be as specified. Putting the battery in the solar system is a little confusing. How to charge, connect multiple and ultimately hooking in to system indicates there are risks involved. Different from lead acid. Successful in getting it installed though

I replaced a Renogy battery battery by this one. It is mounted on a Thor Magestic 23a from 2014 and honestly I don't see the difference with the Renogy (except for the price!). The full solar system is Renogy, and the AC-DC is an 45 Amp - WF-8945-AD from WFCO. Battery is truly 100Ah and discharge 98% of it (I guess I lose a bit on the cable and the monitoring systems). I had the occasion to test it during the last polar vortex this winter when temperature fell is the 10s and the self heating feature seemed to do the job according to the Renogy battery monitor and inverter.Very happy with this purchase.

This review is only on the company's misrepresentation of in-stock items and shipping.On November 27, 2023 I placed an order for two of these batteries. At the time, the add stated that the batteries were in stock and would arrive by December 4, 2023. On November 28, I received a message that the batteries had been shipped. I then contacted LiTime and asked for a tracking number. They said they did not have any of the batteries in stock and it would be around December 11 when they would be in stock.On December 11 I contacted LiTime again and asked if they had been shipped and they said it would now be December 20 before they would be shipped. I said that would be too late and asked for a refund which I received the next day.So, my complaint is that if there are no items in stock, the add should not state that they are, and that stating the items have been shipped when they have not. Even today (December 13) the add still states the batteries are in stock when they are not.
