Style: 12.8V 100Ah Group 31
I replaced a 2,000 pound lead acid forklift battery with 6 of these, 3 in Series, 2 strings Parallel. They easily run the forklift around and i measured the draw at 200 amps lifting 1500 pounds. Between the two strings they are capable of 400 amps for bursts which will easily handle any excess surge loads. There is plenty of room for additional batteries if i needed more capacity and i bought a lithium 36 volt charger (120 volt) the size of a shoebox that replaced the 3 phase 200 pound box that was the original charger. These batteries are doing a great job, powerful and efficient. I will add more counterweight to make up for the lack of the monstrous lead acid battery if I need to pick up more than 3,000 pounds. Overall these saved me money, are powerful, and got rid of smelly, dangerous lead acid batteries.

Style: 12.8V 135Ah BT Group 31
I bought the 135ah version and got it on sale when they had it at 30% off. A seriously good deal for a 1700+ watt hours of deep cycle battery that you can use daily, with proper care, for 10+ years. My use case is simply powering my workstation (MacBook Pro, two monitors, etc..) via solar power as a prelude to going full solar. I have the battery attached, via a 12V accessory socket, to a small 300 watt hour solar generator and simply power my devices off the solar generator. In this setup I can easily run my workstation on solar power without ever attaching to the grid. Remember when you first get the battery to charge it to 100% before using it. Also, the app is pretty good. I didn't have to give up any super secret information or anything to use it. However, it is on your phone so....

Style: 12.8V 135Ah BT Group 31
So far it's been an amazing battery. It runs my Newport 55lb trolling motor, 12 deck lights, front and rear safety lights, 2 charging ports, 4 switches, and my Humminbird Helix 9 Mega SI fish finder for a full day with plenty of juice to spare. And that's with heavy trolling motor usage. Using all the equipment normally (lights on and using the trolling motor only when needed, not maxed out), I could probably get 8-10 hours on a full charge if I had to guess, maybe more. It connects to an app and it shows you how much battery life is left and the current voltage and everything. It's a great battery. I highly recommend it, especially for fishing kayakers with fully equipped yaks. Measures 13" long, 6¾" wide, and 8½" tall body (9½" tall including the posts)

Battery is well packed with good side bottom and top padding. After unpacking, tested battery with multi meter testing DC voltage (13.32 VDC) battery has black and red protectors at each post. I have not yet mounted this on my travel trailer, the battery itself is the approx size as a group 24 lead acid

Style: 12.8V 100Ah Mini BT
Excellent battery for the price. At first I was a bit skeptical because I did not know the brand I took a chance on it and am I happy I did. Yes I had to wait a bit more for shipping, but in the end, it was well worth it. This mini size is perfect for my needs on a kayak. It also has the added convenience of having a Bluetooth battery level indicator on it on it. Trust me, I spent almost an hour and a half browsing various competitors and this is one of the best lithium batteries and excellent 100 amp hour life that you can get especially for the money. Highly recommended.

This battery quit charging within days of receiving it. Found that the item is NON-Returnable to Amazon and the so-called "Warranty" from the distributor is an absolute JOKE !!! ~ ~ ~ Decided to open the top and see what's inside where we found Heavy moisture and condensation within, like it had been submerged under water at one time. I let it dry out in bright sunlight for a few hours, reassembled the unit and now it charges....For how long we Don't Know. Looks like the heavy moisture may have been shorting out the circuit board for the BMS and was keeping things unable to be reset. What a disappointment from AMAZON !!!!!!!

Amazing battery and Bluetooth app is excellent! Battery life is excellent when connected to 55lb trolling motor. Highly recommend; also the size of this battery is very compact. I would like to buy a 2nd battery.

I’ve wasted so much money on lead acid batteries to run my off grid cabin. I guess you can call it “afraid of the unknown”so I decided to give this battery a try and I am simply impressed because it runs everything that I have on 110 V without any struggle for hours. I’m so glad I made this choice. My only regret is I did not buy two at the price I bought this one so TCB worth /Amazon if you can give me another battery for the same price as what I paid for this one I will buy another one.
