Review: 1/11/24 update - Even Lower sale prices. Exceptional Value in LIFEPO4 - Will buy again! - Update: With the drop in Lithium prices, the "buy at" price for these is now $185. I purchased another at this price on Jan 11, 2024 and I am again totally pleased with this brand. I do hope they apply similar pricing to their higher capacity models as I would love to give them a try. I strongly feel that price informs value and try to include the price I paid in my reviews. I highly recommend everyone do the same. In this case, i paid $192 for the 100ah version on October 27th and was so happy I purchased another on Nov 7th 2023. I would buy again without hesitation at the $205 price of this battery today. TL;DR is this is the first 100ah LIFEPO4 I have seen on desertcart for under $200. It meets capacity and current ratings, was well packaged and they made multiple overtures to check if I had questions, etc. It is a no-brainer buy and I will certainly consider more of their products in the future. The price for 100ah LIFEPO4 has been trending down from $300 towards $200 for the last 6 months or so. TimeUSB was the first I have seen to break the sub $200 barrier, so I thought it was worth trying out. I am super glad I did. Packaging - Battery fully enclosed in thick foam and thick carboard box. I don't even think Prime drivers will be able to harm these. They include the terminal bolts and caps for the posts embedded in the foam, nice touch! Looks - honestly this is a non-thing as most folks aren't displaying these batteries. but they have a fun (if comical) red, white, and blue motif with a lil mascot. I welcome a bit of levity in product design. The straps appears to be more than adequate for the weight of the battery. Performance - I'm not an supported influencer, so I don't have all the review tools. However, I know that my cheapo Renogy inverter is about 85% efficient for the load I tested with. My total output on the AC side of that inverter was 1162 w/h and 1165 w/h respectively on the two rounds of testing I did. Some quick maths later and this is actually storing (slightly) more than it is rated for. I also tested with 90 amp load and it had no trouble. Amazing for a battery to perform like a Battleborn, but for 80% less money. Communication - another tiny detail, but worth mentioning. They made communications after each order to ensure I was happy and to tell me to reach out with any questions. Since everything worked as advertised I can't comment on CS. I will try to update my review if there is anything notable in the life of this battery, but a dozen or so cycles in I don't think there is a better value in LIFEPO4 today. The quality of this battery has really me want to look at a few of their larger batteries for another project, so another review likely incoming. TIMEUSB is my new go to LIFEPO4 battery brand! Disclosure - There is none! but I'm including jic as positive reviews are often suspect. I have not had any contact with this company and paid for both batteries myself. just a great deal on a great product that I wanted to share with others.
Review: Good Batteries-Excellent Customer Service - Good high quality true deep cycling batteries built tough with excellent customer service. Although I've installed a lot of solar since the 1990's, I am now sold on using Lithium Iron Phosphate on home solar installations to replace more typical lead-acid type batteries. Also perfect as an RV house battery. First thing I noticed was that their "Users Manual" was exceptionally well written and easy to read without any confusing language or translation errors. This was a welcome beginning. Communication with the seller, Time-USB is also nothing less than excellent. They gave me a heads-up when the batteries shipped, and they arrived very well packaged with plenty of protection and sooner than expected. If you have technical questions regarding set-up, the folks at Time-USB will be happy to walk you through the process quickly. I worked with Tanya and Gerri, who I found very knowledgable, easy to understand and answered all of my questions completely. I'm liking these new batteries because they are much lighter than Lead-Acid, much safer than most other Lithium-ion types, and if they work as specified, they will be far less expensive in the long run. Unlike lead acid, which can only tolerate about a 50% depth of discharge on a regular basis, you can discharge these all the way down without damage thanks to the built-in battery management circuitboard, or BMS. Although you will get more cycling lifetime if the depth of discharge is more conservative. These batteries work wonderfully along with a good quality, properly configured charger or solar charge controller, like the Morningstar Tristar MPPT series pictured, although custom settings were required. I'm also using Victron's BMV-712 Smart Battery Monitor with Bluetooth to easily and remotely monitor the system's production, battery status and power usage. Another nice thing about LiFePO4 (or LFP) is their very high (99%) charge efficiency compared to lead-acid at 94% or much lower as they age. Speaking of age, if installed and configured correctly, you should theoretically be able to get up to 5x the cycling life from these Lithium Iron Phosphate (LFP) type lithium-ion batteries, perhaps up to 10 years making these a perfect choice for off-grid solar or similar high cycling, high demand battery systems. Lastly, if you should have a problem, Time-USB tech support will resolve it, they also have a 5 year warranty on their products. I've ordered from them 3 times, and always had a good experience. Quality Built Tough!
