12V 100Ah Lifepo4 Lithium Batteries Up to 3000-7000 Deep Cycles for Golf Cart Solar RV Camper Marine Battery (12V100AH black)

The media could not be loaded. Did a quick discharge test. Pulled over 97ah with voltage at 11.77 at end. I pulled on average about 800 to 900 watts using a heater on low. I believe this battery is capable of delivering the full 100ah, but didn't feel the need to torture the battery to fully prove it.A few notes- Battery would pull up to about 105 or 106a and BMS would kick in. I ran a regular vacuum cleaner off one battery, don't recommend this, but nice to know the battery can supply the full 100a if needed.Did kick in over current protection when I initially plugged in a 2000 watt inverter. When I precharged capacitor, this wasn't an issue. Just use a resistor to connect battery to inverter for about 5 seconds (bonus- eliminates spark). I actually look at this as a positive in that listed over current protection for surges over 250a works. Easily woke it back up by waiting a bit and then using a lifepo4 charger. It came back on.Listed 2000 cycles at 100 percent is down to 70 percent of battery capacity at end. Other sellers use 80 percent capacity left as baseline for lifepo4 batteries. But other sellers may also not report it in terms of cycles using 100 percent of battery capacity, so always read the fine print. Lead acid batteries, for example, frequently report life cycles using 50 percent of capacity.Recommended charge appears to be .1 to .2c with a max of .5c, recommended seems lower than other LiFePO4 batteries?Overall, I am fairly happy with this battery. Will update if I have any issues. I believe it will last long enough for my purposes, using in a home built power station. One battery should supply a 1200 watt inverter.

Battery stopped working after only 1 year. I only drained it maybe 20 times. And now their customer service won't even respond to my messages. I highly advise against these batteries and company. A couple extra dollars on a real battery would go miles. Or just get a good old fashioned lead acid

More than expected. Arrived in perfect condition ahead of schedule. Battery has a power switch,2 USB ports and a charging port. None of which are mentioned in the description . Directions are vague but good enough to install it. Lite weight. Definetly going to be a big weight savings over the 2 lead acid batteries it will replace.

Product is great, but delivery service deplorable. At no time since I've lived at my current address has FedEx ever delivered correctly. This time I went so far as to call them directly before delivery with specific instructions and they still misdelivered.

I have 4 of these purchased 3 years ago. 2 are the grey version and 2 are black like this one. The black ones have been excellent and still outputting over the rated capacity. The grey ones however have both dropped under 50ah capacity.

With a bit of suspicion about the quality of the “cheap” lithium from China I pulled the plug like at a casinoand bought one to try thinking I would lose almost $500 if I were unlucky. The battery came a week later, apparently from a warehouse in California. I charged it with the charger included. I installed in my travel trailer. It is a perfect fit. I have not done boon-docking with my RV yet. At RV parks I have tried twice to use my coffee machine and microwave by turning on my 1500 w inverter and with the shore line turned off. The battery can make coffee and power the microwave but not at the same time limited by the inverter of 1500W.So far I have used it for a month, no issue at all. Now I went ahead bought another one for my RV to 12 volts 200 ah now.Time will tell. I hope these two lithium batteries from China will serve me well.

Able to charge 4 x 6s 5000mah lipos at 2c, at once with 2 ichargers - that’s 40 amps at once! Only one outing with this set up so far, withdrew total ~65ah to charge 9 of same lipos. Curious to learn real capacity limit. Super pleased with ease of use and convenience. No more generator needed for one day of flying.

Update Nov 2024: I have an issue with this product that should be covered by the warranty and I sent the seller an Amazon message 5 days ago and they have not yet responded. This is greatly decreased customer service since I last contacted them. In a few days I will update this review telling everyone if the seller takes care of their good customers and honors their warranty. - They still have not responded after more than 5 days and me sending them 3 messages via Amazon.Totally unacceptable customer service from the seller of LISUATELI batteries and terrible quality of the product. I paid near $500 for the first few batteries that claim to have a 5 year warranty but now the seller is non responsive. Do not buy this product and do not buy other products, if they have any, from the seller.Old Aug 2021 review was: I now have 8 of these batteries running in parallel. One of them arrived with a problem, but within a couple of weeks I had a replacement. I have been using these for several months and they have shown that they have the stated capacity and more. I gave them 5 stars on Longevity, but time will tell if that is true. I expect these to work well for at least 10 years, and by then I will probably have upgraded to some new technology battery that has not been invented yet, that is even better than LIFEPO4.
