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 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.

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 In a recent order, I accidentally ordered a newer version of the battery that is too big to fit in my camper’s battery compartment.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!

Replaced 2 dead grp 27 lead acid batteries with 2 of these. Bought on prime day w a wee more discount. Arrived as expected well packed. Install was easy once shoe horned in. We have 2 100w solar panels & rover20 mppt controller. Turned off RV converter as it’s not LFP compatible & will only use when using RV for bulk charge as needed. The app for monitoring & interface w battery is nice. Hopefully will have double capacity and more ability to dry camp plus longer life. Happy to have onboard heating and sophisticated BMS so I don’t mess up these expensive batteries though neglect or ignorance. Fun learning about solar & battery power too.

Works great! Upgrade for small rv

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!

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.

I have had this battery for 1.5 years and it has been wonderful. Off grid camping used to be a stressful situation with our two small kids worrying that we were always going to run out of battery. With this unit we always have enough for everything we want to do. We recharge during the day with a 100w solar panel and even in cloudy weekends never dip below 50%. Impressively, I had to email customer service this past weekend because the battery stopped taking a charge. It turned out to be pure user error on my part but even though I am well outside the return period they promptly replied with the solution (completely disconnect the battery from the load- not just turn off the battery cut off and let it sit for an hour or so). I am very impressed with both the battery and the company. If you need a great battery for camping in a travel trailer, this is the battery you need.
