12V 7AH LiFePO4 Battery, Built-in 7A BMS, 5000+ Deep Cycles Rechargeable Lithium Battery, Lithium Iron Phosphate Battery for Fish Finder, Alarm System, Lighting, Small UPS

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 In a recent order, I accidentally ordered a newer version of the battery that is too big to fit in my camper’s battery compartment.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

100Ahを購入しましたが、テストで210Wの負荷で5時間程度動作したので、容量的にも問題ないと思います。 (210*5=1050Wh程度で1280Whより少ないですが、1280Whは多分10時間率で計測した場合だと思うので、今回は5時間率なのでこれくらい(1050Wh)の値でも妥当なのではないかと思っています。) 現在は車載バッテリとして150W程度のソーラーパネルとチャージコントローラーを接続して使用しています。 45Wのポータブル冷蔵庫をつけっぱなしで1日以上使用しても1割も減っていない感じでした。(コンプレッサが動くのは「たまに少し」なので充電なしでも数日は軽く持ちそうな感じでした。) 最終的には220Wのスポットクーラーを載せて使用する予定です。(寝るときに5時間程度動かせればと考えています) 説明書も日本語で分かりやすく、電圧と残り容量の目安の表などもあって助かっています。(BTなしのやつなので。) 他のもっと安い100Ahのバッテリも買いましたが、ちょっと容量が怪しかったりする物(実際には90Ah程度もなさそう)もあったので次に買い足すときはこちらのバッテリにしようと思います。

ソーラーに使っています

我が家の車は充電制御つきなので、イグニッション電源も接続し、ソーラー＋走行充電を両立。 レノジーは30A仕様。 インバータは搭載してますが、 まだお湯沸かしたりしてはいません。 これからいろいろ試してみたいと思います。 まだ日が浅いので星４つで。

在庫15台あるとゆうことで二台目を注文しましたが、到着に10程かかりました。どう考えても遅すぎるわ、怒り💢ます。品物自体は満足してます
