12V 100Ah

I am very impressed with this 12V 100AH LiFePO4 deep cycle battery. It has all of the features I was looking for in a deep cycle battery, including a long lifespan, high capacity, and built-in BMS. I have been using it in my RV for a few months now, and I am very happy with its performance. It has plenty of power to run all of my appliances, and it holds its charge for a long time. 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 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!

Seem to make great batteries I have 2 of the 100ah batteries. This one is going in a kayak for fish finder. Seems well made and the company responded and is sending out screws for the terminal which is great.

Light weight, easy to move if needed,great price for starting to see if solor is for you,can be connected in series to help with longer amp hours

The media could not be loaded. Amazon stepped in, and rectified the situation. But I would prefer buying from amz prime seller next time.I initially purchased this battery due to its attractive price point, hoping it would be a worthwhile investment. However, I received what appears to be a used battery. While the exterior of the battery looks brand new, the internal cells seem to show signs of use.First, the battery wouldn’t charge beyond 96%. I ran tests because both batteries I received discharged unusually fast. Typically, new LiFePO4 cells have internal resistance values between 1 mΩ and 10 mΩ when freshly manufactured and before significant use. Both batteries I tested showed internal resistance values exceeding 30 mΩ.To verify this, I used a resistance tester specifically designed for 100Ah lithium phosphate batteries, and I repeated the test multiple times. Additionally, I manually calculated the internal resistance using the following formula:**R_internal = V drop / Ioad = 0.04V / 1.0A = 40 mΩ****Test Results:**- Open-circuit voltage (OCV): 13.38V- Voltage under load: 13.34V- Current under load: 1A- Internal resistance: 40 mΩThis is not acceptable for a brand-new LiFePO4 battery.An internal resistance of 30-40 mΩ suggests the battery is not performing at peak efficiency, which is concerning for a supposedly new battery. If this battery has been in use for some time, the increased internal resistance indicates potential wear or degradation.**Seller’s response:**"The battery tester you used is not compatible. There’s nothing wrong with the battery. You can use a voltmeter to test it. Lithium batteries don’t have CCA."**My response:**The testing device I used measures the simple resistance of any battery, including lithium phosphate batteries, as demonstrated by the attached results. I also purchased a second tester to confirm the readings. Additionally, using basic math based on voltage and current under load, the battery’s resistance clearly exceeds 30mΩ. While it’s true the battery technically "works," it is not what I paid for—this is a used battery.I understand the price was lower than the competitors, but I still expect to receive a new product.

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 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.)

So far so good. It took a charge just fine but I haven't had a chance to put it on my Electric Trolling Motor and see how long it will last, but we are going this Friday and if there is a problem I will Report back.
