I would highly recommend this battery to anyone looking for a high-quality deep cycle battery. Here are some specific things I like about this battery: - Long lifespan: This battery is rated for 5000+ recharge cycles, which is much longer than traditional lead-acid batteries. - High capacity: The 100AH capacity provides plenty of power for even the most demanding applications. - Built-in BMS: The built-in BMS protects the battery from overcharge, over discharge, and short circuit. - Lightweight: This battery is much lighter than traditional lead-acid batteries, which is a major advantage for RV and marine applications. Overall, I am very pleased with this 12V 100AH LiFePO4 deep cycle battery. It is a great option for anyone looking for a high-quality, long-lasting deep cycle battery.

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 In a recent order, I accidentally ordered a newer version of the battery that is too big to fit in my camper’s battery compartment.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

Why did you pick this product vs others?: Price was right seemed well build plenty of power will be part of a simple solar system that keeps the light on and battery charged in a tool shed far as quality only time and use will tell

After seeing how much capacity my battery lost over a couple of years of light duty and contacting the company about this, NOW THEY TELL ME... Don't use too much... Don't let go below 30% (What? I thought that LiFePO4 batteries could be used down to 0%, Unlike those lead acid batteries???)... Don't charge it too quickly... Don't discharge it too quickly (too quickly = anywhere rated output)... LifePo4 batteries are very prone to damages from use, please do not use them, since they are very delicate... Since you did not charge it every week it will be damaged... If you charge it too often it will be damaged... Did you fully charge and top balance your battery every cycle... If you use it in warm weather it will be damaged... If you use it in cold weather it will be damaged... So Basically, however that you use your battery, just like how you would use any other battery, it will damage these batteries! Now, About Those Warranty Fees... It comes with a five year warranty, Right? Well, maybe you don't know about the fees? See, you must pay them when you want to have it replaced under warranty after it fails, but maybe they did not mention that part to you anywhere in their listing, or maybe they did not tell you about this part when you asked about their warranty either, until your battery needs replaced... Please realize that once you have to pay shipping and the prorated portion of the battery cost, you have nothing. There will be no reason to use the warranty because it would be much quicker, easier and cost you less to just purchase a new battery from another seller. My battery was used in a small solar setup that ran a light load of fan and LED light. Here was their response to why this battery lost so much capacity: A 20% capacity fade of a 12V 100Ah lithium iron phosphate battery after three years of use is mainly caused by the combination of "regular usage + slight lack of maintenance", and may also involve a small number of extreme operating conditions. Typical scenarios are as follows: 1. Slight improper daily usage habits Failure to adhere to regular full-charge calibration, such as long-term charging and discharging only within the 30%-80% range. This prevents the Battery Management System (BMS) from accurately matching the cell capacity, accelerating capacity fade. Occasional deep discharges, such as allowing the battery level to drop below 20% or even 10% multiple times before recharging. Deep discharges of lithium iron phosphate batteries increase cell wear and tear. Relatively high charge-discharge frequency. If there is one cycle per day (365 cycles per year on average), the total number of cycles will exceed 1,000 after three years. Even with regular maintenance, this may result in an additional 5%-8% capacity fade compared to low-frequency usage. 2. Impact of environment and operating conditions Long-term exposure to extreme temperatures, such as immediate fast charging after high-temperature exposure in summer, or high-power discharge in low-temperature environments in winter. Both will intensify the internal chemical reactions of the cells and accelerate capacity fade. Frequent use of high-power fast charging. The large current of fast charging increases cell heat generation, which accumulates wear and tear over time and causes an additional 3%-5% capacity fade compared to slow charging. If you do need to replace the battery, a warranty fee will apply in accordance with our warranty policy.

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.

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.
