12V 200Ah LiFePO4 Battery, 2560Wh Lithium Deep Cycle Marine/RV Battery with Built-in 100A BMS, Ideal for Trolling Motor, RV, Solar Panel Systems, and Off-Grid Power Solutions (1 pcs, 12V 200Ah)

A solid battery but make sure you get the correct ah for your application!I bought this battery to power a minn kota ultrex quest trolling motor on a small fiberglass bass boat (18'). I went with 50ah based on multiple reviews and online forms that stated this battery will last all day and at times two days. After using it for the first time i was impressed how long the run time was, but this is not a big enough battery for my application. 50ah is not large enough for fishing windy conditions on bodies of water with current. With moderate use it only lasted about 4 hours, and in some conditions even less. With that said, i plan to purchase a second 50ah battery to run in parallel and i will be sticking with this brand. Also, since this battery is not bluetooth enabled it was impossible for me to monitor the battery level as i used it. I would suggest a bluetooth battery to anyone that plans on running their trolling motor moderately hard so you're not stranded down river or down wind of your boat launch.

LOVE these batteries! AMAZING customer service too! (no issues but they contacted me to make sure I was happy with my purchase)I have had them over a year and they hold a great charge in my toy hauler even when running my inverter to watch movies and even running my electric coffee maker off grid.Recommended a set to several of my friends!

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 Amazon 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.
