I am amazed at the functionality of this battery, especially at this price point. I use this as a second backup battery in my overlanding truck and it replaces an aging AGM battery. My light bars and max air fan are powered by this backup battery and in the past I just had to guess at how much load was present on the AGM battery. The App this battery connects flawlessly to is a game changer. Shows everything, voltage, amps and volts being drawn, the voltage of each cell in this battery, charge cycles, temperature, whether it is charging or discharging, you name it. And you can control the battery through the app although it handles low temp shutdown automatically. The price is amazing, the functionality with the app is amazing, even the manual is wonderful. No poorly translated manual from Chinese to English here. Just a full color, detailed manual with all info you could possibly need. I will probably be buying another one of these if not more.

This review is for the Cyclenbatt 100Ah LiFePo battery with Bluetooth. I received the battery a few days sooner than I expected and it was well-packaged to reduce the possibility of damage during shipment. The price was much cheaper than the other brand of battery I purchased 2 years ago so I was a bit leery but I understand that economy of scale has brought the price down on these things immensely, and it had mostly great reviews. This battery has Bluetooth built-in which communicates with a phone app available for both Android and Iphone. The app is handy, allowing you to monitor the battery's state of charge and discharge and other functions, as well as turning on/off the charge or discharge. It comes with about a 60% charge on it for safety during shipment and I charged it the rest of the way with no problem, per the comprehensive instruction booklet that came with it. It integrated well with my LiFePo capable solar controller. I'm a ham radio operator and the intended purpose of this battery is to power my 3 radios, a couple lights, a laptop, as well as to charge my phone, flashlight, etc, during power outages which happen all to frequently during storms here. This battery easily handles that task, and could power these items for probably a couple days straight. Once I get a pure sine wave inverter I'll be able to run my fridge for a few hours at a time too if necessary. I would certainly recommend this battery.

Definitely has the marketed capacity (per the BMS and voltage at various stages of charge, it appears to have around 104Ah, so likely 26Ah cells; I really appreciate them being honest and conservative with their marketed rating). No clue on ultimate life span yet, but I have been using it every day since it arrived and will update this periodically over the next ten years or so (roughly the expected usable lifespan), assuming it is still available. I have also noted that the cells are very closely matched, though I’m not sure if this is a feature of the type of cell or if somewhere in the supply chain they get characterized and matched. Based on my experiences with inexpensive examples of other types of lithium batteries, I planned for the worst possible scenario and have been pleasantly surprised. I charge it at 20A (0.2C), which replenishes a day of consumption for my application in a little over an hour and a half, though in a pinch it has enough capacity to handle 3 full days with a reasonable buffer (around 5 hours to recharge all the way). The built in BMS is an off-the-shelf unit from JBD and can be read/controlled using the aiobmsble Python library. Their app is decent, easy to use, and the BLE range on this BMS is extraordinary. The BMS only delivers data to one client at a time and consumes more power when doing so, so keep these in mind if you read from it with a computer. Personally, in addition to the main loads, I have the battery supplying power to a converter that powers a Raspberry Pi Zero 2 W, which is running software I wrote to log battery data and manage the equipment around the battery. The BMS seems to have difficulty accumulating the consumption of very small loads like these, so just be aware of it. With more typical loads that exceed ~1A, accuracy is good. Lastly, this battery is a non-standard size. In my particular case, the fact it’s smaller is great because it fits in a type 27 box with plenty of space to spare for everything else I have connected to it, like the charger and DC-DC converters. YMMV

Style: 12V 100Ah Bluetooth Mini
First time purchasing from this seller and this battery is exactly as described! I expected to find it not 100AH for the price after past experiences with other sellers, not this one, sending a battery rated as one capacity and tests showed it half that. When I received it, I compared it to the 50AH I have that has the same size dimensions as this battery. Right away it was heavier indicating that it should contain larger capacity battery cells inside. I did an initial charge upon receiving it and used the app to monitor. The temps remain stable and good. The 4 cells charge pretty equally during the whole charge process and were a little unbalanced by around .04v and only at the end of charge but letting it sit for a few minutes they level out almost completely equal to each other. Next, I did a capacity test and discharged at 140W which took several hours but the total capacity ended up being 105AH! That was a pleasant surprise. It charged at the max of my charger at 20Amp without any issue in about 5.5hrs. I don't foresee any issues with long-term functionality or durability. The app was extremely easy to use and gave accurate, real-time information about the power going, coming in and the state of the cells. I can also enable or disable both the charge and discharge functions from the app. The battery case is sturdy and heavy duty and doesn't feel like it will fall apart. I was glad to see that it was the same size as my 50AH battery which made it a drop-in replacement in a tight tolerance space. The battery came with 2 sets of bolts of different lengths, which I liked, allowing me to use it right away vs having to go to the hardware store before I could even use it. I think what I got for what I paid for is well worth it and it was cheaper than most other listings on Amazon. Based on this experience and the quality of the product, I will definitely by some more in the future.

I was looking into this battery for awhile, and when I saw a sale come up I decided to jump on it. This battery is an absolute great value at its price point. I plan to use this battery for multiple purposes. I’ve been primarily using it as a small backup power source in my home to power my refrigerator/freezer in case of a power outage. During my testing, I was able to power my refrigerator and freezer (two appliances) for over 8 hours without the help of solar, and they are older and not as power efficient. If you have newer and more efficient models, you may get more run time out of this battery. I simply have a few solar panels, this battery, and a inverter to run my AC appliances in the event of a power outage. The setup is simple but it’s been working great. I have been able to draw more than the listed 100ah from this battery, which is impressive given the mini cells used. This battery is also perfect for my ham radio and my fishing boat motor. I can literally use them all day on this battery without running out of power. The small size is what drew me to this battery as it can be easily moved around. This battery is so light, and with the included handles I can move it around anywhere without problems. I’ve essentially been able to build my own solar generator using this battery, and because of its size, it’s just as portable and has more capacity for the money than any solar generator you can buy from the store. I opted to get the version without Bluetooth, as I have a separate battery monitor. This saved some money and I don’t feel like I am missing out on anything. If you don’t have a separate battery monitor, I would recommend spending the extra money on the Bluetooth version as you’ll be able to monitor the battery from your phone without an additional device. I haven’t tested the low temperature protection yet, I opted to watch battery teardown videos on YouTube to see this battery’s build quality and testing of individual components. According to those videos, this battery had problems with low temperature protection in the earlier models, but has since been fixed for some time now. I look forward to testing this for real this winter using real world conditions here in the north. I don’t doubt that this battery will last for a very long time. I’ve been very impressed with it so far. You won’t regret purchasing this battery, especially at this price.

I bought this 2 pack cyclenbatt 12V 10Ah LiFePO4 to replace cyberpower CP1500PFCLCD battery after read someone else review for compatibility. Also considering 5 years warranty while other brands 1 year only. What I don’t like: * No production date stamp on battery case like agm battery, mean you don’t know when it manufactured. * Both batteries voltage is 13.2V when arrived and capacity around 50-60%, after full charge I leave it one night rest 13.7V & 13.8V. Not good, manual said 13.9V when full Thing to notes: * Manual said to fully charged before used * Make sure charger have mode/support LFP or LiFePO4, no go with charger for lead acid battery only. * If you need install upside down, you can as long positive and negative terminal fully isolated from other metal/conductive material.

A great battery for an attractive price. Two were easily installed in an older UPS, as a direct replacement for lead-acid gel cells. The Battery Management System in these units generally permits the battery to be installed in products originally designed for lead-acid batteries, preventing over-charging, overloading, and damaging excessive discharging. Don't be misled by the caution in the manual regarding lead-acid battery chargers. It appears to refer to external "fast-chargers," not those found internal to battery-operated devices.

I used these batteries to replace some old lead-acid batteries in my CyberPower ST900U UPS units with excellent results! They are well constructed, and the physical dimensions of the batteries are within millimeters of being the same size as the older style batteries, fitting into the battery compartment of the UPS units perfectly. The PowerPanel software that I use to monitor the units recognized the batteries immediately, and was able to read all of the relevant vital information from them. I've had them in use for several months now, and they have continuously passed many intentionally initiated self-tests under load without incident, and report plenty of potential runtime. Although I obviously don't move them around much, these new LiFePO4 batteries make my UPS units so much lighter! Having been accustomed to using lead-acid batteries for so many years, the difference in weight is astounding, and very impressive. I will definitely be using these batteries for all of my needs moving forward. As an added bonus, CYCLENBATT took the time to make the presentation of their product elegant, both with their packaging and documentation. Highly recommended.
