    I like the nearly $400 or so cheaper than the “Made in USA” brand since the actual Lithium cells all come from China (there is no Lithium mine in USA) So, does that mean that “assembled in USA” should cost $400 more? Also, the supplier includes the charger (a $30 value – check Amazon) and port to charge the battery from grid power. There is a voltage meter in between the USB ports, a glowing switch (button) cuts power to the meter and USB ports. The rubber covers for the charge port and USB/meter complete the package. Oh, wait a minute, are those gold clad battery posts? Why yes they are…

    Purchased the 12v 40ah to power a charger box for camping, and charge it with a solar panel. It charges way faster than the lead-acid battery in my first charger box. Last week, I went to use my charger and it wouldn’t turn on. I contacted the seller and was informed that the lithium-ion batteries require a different charging setup than lead-acid batteries. I very impressed with the response and solution to my problem. I’m so satisfied with the customer service I received! I’ve tested the capacity and came up at 520W-hr at 0.3C discharge rate, so was very happy about that. I use this battery to run about 100W worth of appliances (lights and an air purifier) through a 300W inverter (separate purchase) and I get 6 to 7 hours of power out of it. I love that this is lithium-based and can be entirely discharged without much effect on its capacity. Great deal. Let me put it like this, I will be buying every battery I purchase from SCREMOWER from now on! I give my Lifepo4 battery and SCREMOWER purchasing experience on Amazon 5 stars.

    I purchased this battery in error, thinking it would fit my 2018 Subaru Outback [an error on Amazon’s “This Fits Your Vehicle” lead me to this incorrect conclusion]. After waiting awhile for this battery to arrive I was really keen to install it, since it has very cool extra features (USB port, digital readout, and airplane power port) only to find it didn’t fit in the Subaru’s meager battery space. After a brief exchange with the Seller they agreed to swap it for the correct battery at no extra expense to me [except of course the shipping fee to get the incorrect battery back to them]. Now I’m set with a race-car worthy LiPo battery for my not quite race-car Outback (which has too many bells-&-whistles sapping power and regularly leaves stock battery’s well below 12.5V).Big praise for this company, Thank You (!)-Daniel (California, USA)

    OK don’t like it took so long , Tested Ran 300 watts FOR 3.75 HRS then battery shut down . Its a little shy on the amp HRS and was fully charged. But i cant say that for sure until i run more test because of the loss of watts thru wire length . charged up in about a 6 HRS . Comes with nice charger it takes a while to charge . Drained it twice and recharged it and it charged to 14.8 volts both times and charger shut off. nice unit for half the price of others .Is the battery out of balance Hmmm! not much that others stated . And really are we dragging this thing a round 24 -7! no most of us install it and leave it so that’s no big concern . I’m Concerned about warranty since it comes from china . Will i buy another yes works great so far for half the price as others,

    This is a double review. Because I purchased 2 L ion batteries from Amazon at the same time. Both were from China. When I first made the purchases. I had second thoughts. Both batteries were about $400 lower in price than any US brand. But China is often slower to deliver. And talking to the seller is sometimes impossible. So, I canceled both batteries. 1 from Fly Power Battery Co. and one from Kepler Industrial. Within minutes both owners contacted me by email and agreed to cancel. That was great, a real live person was easy to reach and talk with. So. I decided to go ahead with both orders. “Boy. “O” Boy” was I ever glad I reordered both L ion batteries. Both Batteries are set up now in my Home off grid survival system. When the power goes out, as it just did this Christmas, I use the “system” to power my TV, Modem. computer and my 11 media players. Also, I power my heating pads and electric blankets for extended blackouts. The Great thing about the battery is everything…!Light, easy to move, very important when you are old, More powerful that heavy AGM or Pb acid, Tolerate a high discharge rate, A Very Fast recharging rate. When our Christmas storm power outage happened my inexpensive China L ion batteries never dropped voltage below 13 to 12.9V. The power was out for 3 1/2 hours. They both charged back up to full charge in 30 minutes. Before putting in my 2 100 amp hours new L ion batteries, I had 600 amp hrs of AGM super heavy, slow to recharge, fast to discharge old batteries. It is very important to get a solar charger that has a L ion setting. I found mine on Amazon. One important benefit of my Amazon China l ion batteries is that they arrived FAST.A little over 3 weeks in the USA. Also they come with a great 120v charger that charges the battery nicely. I love and the friendly, kind, professional sellers communicate faster than most US sellers. Here are a few picks of my amateur “solar survival system” and the China L ion lovelies installed in my bedroom.

    I bought the 240Ah 12v for a sprinter van build, I’m an electrical engineer and have worked at the Tesla Gigafactory in Reno where we make similar batteries, these battery cells are made in the Gigafactory in China. Great buy. Under $1k, delivery was about a month.

    Tired of charging and charging and charging your conventional Lead-Acid batteries? Tired of Acid burned clothing? I paid $500 each for three of these. They are now selling for $460!Up till recently, they were selling for $1000 +My previous deep cycle Lead-Acid batteries (of which my battery bank consisted of six) each weighed 63 pounds. These puppies weigh 27 pounds each! Reducing the weight of my fifth wheel pin box tongue weight on the bed of my pickup truck significantly. O.K. Let’s get down to the brass tacks. Lead-Acid batteries are like a glass of beer. If you allow the batteries to discharge below 50%, the batteries will never fully charge to their original optimum charge. When you get a glass of beer and you see if full with a lot of suds on top, the glass may be full but it’s not all beer. Same with Lead-Acid batteries. Full charge and surface charge are two different things. You can apply a charger until hell freezes over. However if the Lead-Acid batteries have ever been ran down past 50% there is no way that those batteries will every recharge to their original potential. So there is the weight of the argument for Lithium batteries. Weight is important. But most important is the fact that you can run these Lithium puppies down and they will charge all the way back up to their optimum. So right now with my trickle solar 160 Watt panel that I have on the ground because my coach is in storage under a canopy, so my coach roof panels are insignificant, my new Lithium batteries stay charged. I run two security lights 24/7 and a 170 Watt inverter to provide 120 VAC for my Burglar Alarm motion detectors also running 24/7.I got these from Amazon Prime and pay $40 a month with no interest. The Lead-Acid batteries were one big pain in the you know where the sun don’t shine. Now I can concentrate on other chores and responsibilities. I am sure that the prices will continue to fall but I do not regret getting these bad boys sooner than later. In addition, my Midtronics solid state automotive battery tester measured 800 CCA (Cold Cranking Amps) across each battery!

    I like the fact that this battery will replace the old lead acid batteries and last a long time. It has the 100 Amp hour storage capacity, built in BMS (I did not have to make this), great battery case, built in voltage display with USB ports, battery charger (10 Amp) and for about half the cost of “Battle Born” Lithium battery. They advertise “Made in America” but, all Lithium cells are made in China and that leaves “assembly in America” which may not be worth $400 more (in my opinion). Four of these would give you over 5 Kilo Watts of storage.

    I bought 2 batteries (12V 100Ah) from them 2.5 months ago. One of them is unstable. Since it is not possible to series connect their batteries for my 24V system, they are rather useless to me, I suggested the 2 batteries be exchanged for their 24V 100Ah that they also sell (I really like the battery enough- the one that DID work – to want to stay with the same seller’s product). Their initial response that I buy the 24V at 15% discount as they cannot exchange them so upset me, that I gave them a one star review. In an instant the seller contacted me and offered 3 different solutions for me to choose from that were more than fair. I always say, it’s not when fortune is on your side where things go right that is a testament to the quality of your company. The test of your company’s character and strength is how you resolve problems and treat your customers to move forward. I do really like these batteries and I’m glad the seller corrected the situation as I would like to be able to expand my battery bank capacity with them in the future .
