12V 100AH Self-Heating LiFePO4 Lithium Battery, Built-in 100A BMS, Supports Low Temp Charging, 5000+ Cycles, Perfect for RV/Camper, Solar, and Off-Grid Applications, etc.

I have 5 of these 100 AH Vatrer batteries and I love them. They are well-built and perform quite well. I have 3 of them in a home solar power system and 2 of them in my camper. Vatrer does a great job of responding to what their customers want and upgrading their products; for example, adding low-temp charge cut-off, self-heating capability, and a Bluetooth interface. I particularly appreciate the Bluetooth connectivity, because it pretty much eliminates the need for me to buy an external battery monitoring device. I can just pull up the app and see what my battery State Of Charge (SOC) is. Additionally, their customer support is quite good. In a recent order, I accidentally ordered a newer version of the battery that is too big to fit in my camper’s battery compartment. I emailed customer support and they responded the next morning with a very generous solution to my problem. I wish all companies had this kind of customer support! In my opinion, these guys have a great product and great customer support. Can’t ask for much more than that! (One word of caution: they are constantly upgrading and improving their products, but they don’t always change the product part number when they do that. When your order, make sure to check the specs to ensure you’re getting what you expect. This is true even when you have already ordered the same product. It may change without warning.)

I have had these batteries for 5 months, they are powering the coach in my Class A Motorhome. We are currently in the dead of winter and have been experiencing below freezing temps every night. The batteries are holding their charge and the heaters are doing their job. Highly recomended!

I have had these batteries (3) for six months, aside from an initial delay in shipment, I have been very happy with them. I bought them for the self heating feature, as I am using them for a campervan with solar panels in a northern climate. The self heating has worked when it goes below -0 degrees F. Do these batteries charge below 32 degrees F down to -4 degrees F, I have not tested that yet but they do work. The BMS with bluetooth application is great, it has a number of features and at least 60 feat of bluetooth range. So far the batteries have self balanced very well and the charge is consistent between all three. I have not done any heavy discharge cycles yet. Using them with my inverter, they can power my microwave and it did start my rooftop 20 year old dometic AC unit but I did not test how long it would run for with 3 batteries. Size and weight: They are group 31+ size, so they are big but not heavy.

Great product and quick shipping!

First the positives. Bluetooth worked and was easy to connect to and use. Battery is light. Negatives. Seemed like it depleted very fast. Tried contacting support but the number on their website went directly to voicemail and the box was full. Tried contacting them through chat, nothing back. Tried email. Nothing there either. Decided to return. They sent an address label but shipping is on you! Cost me $46 to return from Denver to California. Still waiting for credit on purchase but don't expect to get the additional shipping back. Very disappointing Amazon! You should specify that we will have to pay return shipping on these!

I recently upgraded to a 12V lithium-ion battery from two lead-acid batteries for a small solar setup, and the difference is remarkable. Much lighter and good Ah/$ YouTube breakdown reveals quality connections and BMS is pretty good. I appreciate the self heating feature.

I purchased 4 of these to use in my 5th wheel, and have grown to LOVE them. The Bluetooth connections are really good…my trailer is parked outside, and I can check each battery from the comfort of my kitchen table or recliner. I had issues in initially setting them up in the bank, but once Vatrer support helped me resolve some issues with one of the batteries, they have worked great and seem to maintain their charge quite well. I believe they are a great value, especially considering the low temperate charging and self-heating functions. Highly recommend both the batteries and the Vatrer support team.

While the price drew me initially to evaluate the 100 AH heated Lithium battery from Vatrer, the subsequent discovery of a bluetooth monitoring capability built into the battery was very gratifying. Checking capacity, charge level, etc, is easy when it's in service. Then, the heated BMS lets you keep it in service (RV in this case) over the cold months. Lastly, the warranty on this battery is generous. I think it's a good value for the money.
