12V 100Ah Mini LiFePO4 Lithium Battery, Low-Temp Protection 12V 100Ah Lithium Battery Built in 100A Smart BMS, Up to 15000 Deep Cycles, Great for Trolling Motor, RV, Solar System, Off-Grid

Well packaged. Smaller than expected, and nice and light for carrying around but plenty of power. Tested low temp charge protect, and it worked as expected. These LiFePo4 batteries have come a long way in the last couple of years. With brand promo and coupon, this was cheaper than lead acid, and provides better power and should last a lot longer. Liked it so well I bought two more.

Small in physical dimensions but very powerful. I put two in parallel for my camper. We do a lot of boondocking and I prefer not to run our portable generator. We charged these off a 100 watt solar panel and never had a shortage of power.The price isn't much higher than a lead acid battery. And the usable power is much higher than a 100 AH lead acid battery. And an extra bonus: these weigh less than half of what a comparable lead acid battery.

I love my new Mini LiFePO4 Lithium Battery from CYCLENBATT! My old battery was a premium AGM (absorbent glass mat) marine battery and this new LiFePO4 is so much better even than AGM. My AGM battery was only going to last 2-3 years while this better new LiFePO4 battery from CYCLENBATT is going to last at least 5-10 years! My new LiFEPO4 battery can be safely discharged to 100% without reducing lifespan significantly, and this is really important to me so that I don't run out of power and can keep the lights on in my RV while camping without any worries! The advantages I've already explained are that "LiFePO4 batteries last far longer, especially with deep discharges." and "You can use more of the total capacity with LiFePO4."The benefits don't stop there and there is even more! LiFePO4 is 50–70% lighter and more compact for the same capacity vs my existing AGM marine battery. My new LiFePO4 has higher round-trip efficiency (~95%) during charge/discharge cycles. Advantages are that LiFePO4 batteries are ideal for applications where weight matters (e.g., RVs, boats). The legacy AGM technology is much heavier and bulkier compared to CYCLENBATT LiFePO4 technology. The other advantage is that LiFEPO4 has faster charging and more efficient use of solar energy or other power sources.We can keep going with reasons CYCLENBATT LiFePO4 technology is better than my existing premium AGM marine battery. Self-Discharge Rate of LiFePO4: Very low self-discharge (~3% per month). Compared to AGM Higher self-discharge (up to 10% per month). The advantage LiFePO4 holds a charge longer, making it ideal for long storage periods. Temperature Performance for LiFePO4 performs well in high temperatures while AGM does not do as well in extreme heat. Advantage for LiFePO4 excels in moderate to warm climates. LiFePO4 is Maintenance-free, with a built-in Battery Management System (BMS) for protection. Compared to AGM that is also maintenance-free but lacks advanced BMS features for overcharge and discharge protection. Advantage LiFePO4 is safer and more durable with built-in protections.Best Applications for CYCLENBATT LiFePO4 battery is RVs (camping), boats, solar systems, and off-grid setups where weight, lifespan, and efficiency are crucial. I hope you will buy yourself a brand new CYCLENBATT LiFePO4 battery to replace your existing AGM marine battery. You can't go wrong with this choice and you will only wonder why you didn't do it sooner.Finally, the CYCLENBATT LiFePO4 is a very nice looking battery and comes to your doorstep in a very sturdy cardboard box with a thick foam inside the box for protection. The instructions are very clear and nicely printed. The battery only weighs about 20 pounds and also has a double handle making it very easy to carry and move around. Please see the photo showing exactly what comes in the box!

This is a great product for someone who is just getting into batteries or needs their own batteries for camping. For the size, price, and now after testing, you won’t find a better setup. Our small setup includes myself and two boys and we run three heated blankets (about 150 watts) throughout the night and we can do that for multiple nights before charging the battery. Still working on adding solar for charging. The sellers page and the included materials were very helpful from and education standpoint. All my questions were answered there. We were referred to this battery by a friend, and it was perfect because of the size and functionality which for us means portability and convenience while camping. It’s was easy to find adaptors to connect to the battery on Amazon for our blankets. It did rest right at 13.4 v right after charge and charged up fine. Planning on getting more in the future.

Perfect battery for my needs. I recently put a shed in my backyard and wanted to run solar for lighting and fans. after wading through the countless batteries I ended up on the cyclenbatt 100ah with BT. The battery is very affordable and works like a champ. It meets all my needs for being able to power the amount of lights and fans which is around ~200 watts for several hours. Instillation was as simple as just putting it inline between my Solar Controller and my inverter. The fact that the battery has BT and an app makes sure I can also monitor the battery to see how things are going and make sure that I have enough power for what I am doing. I will definitely use these batteries for any additional projects that require a good sized battery.

Fast shipping via FedEx. I hooked this battery up to my solar setup. Everything works as it should. It accepts a good charge and holds it. It also last a very long time for my needs. I love that this battery is smaller than my past batteries. So I can get a few more and they will fit where i need them to fit. It’s not very heavy so it’s easy to move around if needed. Very happy with my purchase. Thanks Cylcenbatt!
