    Good longevity

    I’ve been using this battery to power a little trolling motor and it works well. By this time in the start of a season when I’m pulling everything out I usually have to buy a new battery. I’ve had this one since last year and it’s still going strong. I think that may be the biggest selling point.

    Perfect Batteries for the boat

    I purchased these batteries to hook up to my trolling motor in my boat. I charged them up and tested them and they both hold a full charge. They fit in the seat box perfectly and are light weight and were easy to wire in. I also have an onboard battery charger and wired that to them also. Everything is working perfectly and after every use i have charged them up and checked them with my multimeter and they take the charge and hold it. I am very pleased with them and give them 5 stars.

    Great customer service

    I have been using the batteries for about 3 months and they have performed very well, much better that the lead acid batteries I replaced. I had a few questions about how to set up the charge controller on my 5th wheel and my questions were answered in less that 24 hrs.

    Amazingly light weight

    I wanted a 12v power source for my golf cart so I picked up this battery. I also got a LiFePo4 charger for it, don’t forget to get that.It’s incredible how light weight this is! You can hold it with one hand with your arm fully outstretched! You can’t do that with a lead acid battery!On my golf cart it runs a set of LED fog lights that I use as headlights, it runs my brake lights/turn signals, stereo, 12v accessory power for my GPS and some blue LED accent lighting. I don’t run all of them at once (I rarely use the GPS anymore) but it works just great for me and doesn’t add weight to the cart! I have a built in charger for the main battery pack in the cart and I mounted my LiFePo4 charger on the cart as well, so one extension cord plugged into the cart charges both systems. Works great!

    Great Deal

    Seems like a solid battery upon arrival. Charges and discharges as normal. So far happy with purchase. The terminals are M8 size bolts. Will update review if longevity becomes an issue but I am happy with my purchase initially.

    Completed my project

    I have been working on so many projects that are related to off grid, solar, self-reliance, etc. that it would make your head spin. This project was for one of my neighbors. I turned is 26″ mountain bike into an e-bike. This battery was just one of the components that helped him to follow my lead.

    12v 100ah – For once, something exactly as advertised

    Great battery. I put it in my kayak to run a trolling motor, which it did flawlessly. In front hatch of Old Town Topwater PDL 120. Without a battery box it barely fits, but does fit. I can’t speak to the longevity since I only had it a couple weeks. The handles on this battery are an overlooked feature that you quickly realize are essential considering the weightI ended up returning it because I want my battery in some type of enclosed box, and the customer service from this seller is awesome. Arrived in about 5-6 days, and they sent me a pre-paid return label making it a breeze to drop off at UPS. I want to emphasize pre-paid. If I had to pay return shipping myself it would’ve cost a butt load.

    Lightweight. Excellent Performance.

    I really like the latest generation of LiPO4 batteries. They are replacing typical lead acid batteries in different industries at a fast pace. That is to be expected as they are lighter in weight, better performing and becoming similar in price. This generic one is still very good. It is likely manufactured from a large manufacturer and label by many different brands. Works great. Good value. 5 stars.

    Nice addition to my emergency preparedness kit.

    These little LiFeP04 batteries are a great way to provide power for12 volt lights. They’re lightweight, clean and safe for storing inside of the house. The next time we experience an extended power outage, we will have 12 volt lamps up and working within just a couple of minutes.These batteries last a long time and they are easily rechargeable with portable solar panels.Although we’ll keep our supply of emergency candles, I doubt that we’ll ever have to use them again.

    Capable battery

    This 204wh battery is a good solution if you need one of this capacity and power rating.The package comes with an informative manual outlining the specs. The max charge rate is 16A at 14.6V, continuous discharge is 12.8V/16A with 3 second spikes at 32A. The manual specifies you can combine a maximum of 4 same make/model batteries in series or parallelTesting its output ability using an inverter with a power meter on the output end, it was able to provide a brief output of 236W, and 50 minutes at a fluctuating load averaging 192W including 10 minutes continuously at 204W (this exceeds the 192W rated discharge of the battery which I do not recommend doing). During this max power discharge, the terminals measured at 105F in a 75F environment as measured by my IR thermometer. Total post-inverter AC output was around 160wh, which is a normal for a 204wh battery.For charging, my 12V, 10A name brand charger was able to charge the battery while consuming 166W of wall power, achieving a full charge in less than 2 hours.

    Great little battery!!

    I really like this little battery. I use it as part of a small solar rig I have set up in my shop to power all my lights, and this tiny guy (or gal, I’m not assuming anything) has done very well so far as part of a bank of 12v batteries in parallel. It always puts out a solid 12 volts, and although it’s part of a bank now, I used it individually for a bit to test how it performed. I really, really enjoy the built-in BMS (battery management system, which keeps the battery from being overcharged or over-used) that provides peace of mind knowing I’m not accidentally destroying my batteries. I’m new to DIY solar rigs, and that’s a very real possibility, so I need all the help I can get.I’ll be picking up more of these going forward for my shop system. I noticed the cost per watt-hour is pretty good with this particular brand, and the performance is great. It holds its charge for weeks without any real drop, which is a little unusual. I hope this was helpful – I’d definitely recommend this brand if you’re looking for a battery for a smaller solar rig.

    Charging + power is great….top of battery coming off

    Battery charges exceptionally well and fast. Power output is great! Issue: 3 months in the top of the battery is starting to lift away from the lower portion. Like it’s swelling or has come unattached. Quite concerning, although has not affected power.

    Great battery for the price

    I have not had a chance to really put this battery to the test yet, but so far, it seems like a very good quality battery and at a very good price. Shipping was fast considering the time some shipments are taking from other outlets. It came a day before they said it would. I am using it for a 1500 watt portable inverter set up that I built. The battery is small and lightweight for a 100AH and fits perfectly in my build. I am using a Victron Bluetooth charger and it charged the battery in the specified time based on the charging amps.Love it so far.

    Great Batteries so far

    Using 2 in parallel on my 5th wheel, largest load is 1kW sine wave inverter powering a residential refridgerator. Typical overnight SOC drop was about 10%. Conversion from flooded lead acid required converter and battery tray replacements. Venting no longer required. So far, I’m very happy with the conversion. Using Progressive 80A Lithium charger/converter.

    For emergency, power-outage use

    I have set myself up for short term emergency power outage preparedness after having dealt without power for a few days. So now I have a pair of these 12V 16Ahr batteries wired in series (and another pair of 12V 18Ahr batteries as back up when these are being charged) so that I effectively have 32Ahr when these are attached to the 2000W inverter. I can still power many items in the house like the microwave so long as I’m not just using over and over and over when the power is off. I also have a pair of solar panels that can charge these (and my other pair of batteries) so that even if the power is off for a few days, I have the ability to keep this battery powered up and ready for use. Always good to be prepared and this battery gives me the peace of mind I need should the power go off tomorrow.

    Super Customer Service!

    I have not had the batteries long enough to do a review on the batteries it will happen later. However I have had contact with their customer service several times with questions. They are great to deal with. Quick to respond they even researched the victron charger I use confirmed charge parameters and even trouble shooting a noise issue that turned out to not be the batteries. If the batteries turnout to as good as the customer service and I expect they will these are great batteries.David

    This is a kick azz battery…

    The media could not be loaded.

     An old 1970 fridge draws 0W out of the inverter once the 1480W start W is completed.. this is awesome… as a new (another addition) to our existing permanent motion electric motors system. 5 stars y’all!!!

    Best addition to my RV

    I upgraded my battery system in my trailer to this lithium battery. I have tested it and can run my trailer for three days without charging. When used with my solar system I can run unlimited days.

    So Far, Fantastic

    I cannot really tell you yet how good this battery is because that can only be determined after several years of use. But right up front I’m very happy with the battery. I’ve used it 7 times so far, on a fishing kayak and a flat bottom 12 boat. It was used for 5 hours + each time for trolling. After each time it was still at 90% capacity. Other wet cell batteries I’ve had (series 28 Interstate) would have been around 50%. I cannot stress enough how light this battery is, like 25 pounds. That is a major bonus, since my past batteries came in about 60 pounds. Hugh factor for me. I’ll get back with an update after 30 times on the water, but right now, this battery has been spectacular.One note: the manufacturer recommends only using their special charger, so that added an extra $30 (for the cheapest model) to my costs. I wanted to use one of my other 2 marine battery chargers, but figured I better not.

    Capacity met…

    This lightweight battery seems well built and works without a problem. It meets all its rated numbers and in my capacity tests, and was what it proclaimed to be. The BMS seems to function as intended. Time will tell how it lasts but right now I am happy with it and would recommend it. Don’t forget you’ll need a lithium-compatible charger to charge this.

    100 AH batteries for golf cart

    I had an initial problem with one of the three 100 AH LiFePO4 batteries used in my 36 volt golf cart but after contacting the factory I received some good support and ideas for charging the battery. The batteries are now working perfectly and the golf cart goes at least two weeks between charges. The cart also runs a little faster due to the 100 lb weight reduction. No more checking water level in the lead acid batteries and all the corrosion from the acid drips.

    Surprisingly lightweight

    This battery arrived about half charged and took several hours to fully charge. Once charged, it has consistent voltage over the discharge until the very end. The battery has onboard overpower and heat protection.I’m using this battery in a UPS and so far I’m very happy with the performance and weight.These batteries are very lightweight compared to lead acid batteries. LiFePO4 batteries are a step in the right direction with emerging battery technology.

    Great value.

    I’ve been using this battery to run my trolling motor. It runs for hours at full speed. It is also extremely light weight easy to carry. I’m also using it for a small solar generator that I built with a 3000 W inverter. I highly recommend this battery.

    Great little llifepo 4

    I had a fault in the system on Monday. The battery seem dead as a doornail I contacted customer service and they got back to me within 12 hours. And gave me three methods to get the battery back to life. I was very surprised when the battery came back to life and all is well now. So the battery management system works as intended. It’s a great battery. Customer service is great and I’ll be looking to buy another one soon.
