Recently Amazon has been known more and more as a place for scams and fake products. Anyone can slap a sticker onto something and call it something else. So when I received this battery, I tested it to make sure it was authentic.
As you can see from the video, I am very impressed with this battery as well as the WINGDA company. The 100AH battery tests as a 100AH battery, and behaves exactly as advertised. The WINGDA company itself went out of their way to provide customer service twice during the processing of my order. I was thoroughly impressed with WINGDA, and I will be recommending them.
A couple of concerns I have are:
1. *After watching my review, WINGDA fixed the BMS to 10.8amps*
*Original Concern* The battery management system (BMS) has a low voltage cutout of 8.8 volts. At such a low voltage, it is possible to permanently damage LiFePO4 batteries. I recommend using a charge controller to protect your battery from low voltage. If you are depending on the BMS, then you are toying with premature battery failure.
2. *After watching my review, WINGDA fixed the listing on Amazon*
*Original Concern* There are a few errors on the Amazon sales page about charging and discharging rates. All of the supplied documentation states a maximum charge/discharge current of 50 amps, but on Amazon you'll see figures of 20 amps or 25 amps. I tested the battery discharge as high as 30 amps and found it performed flawlessly. But the errors do create confusion and less confidence.
3. The dimensions of the battery on the webpage are very good. The battery itself is slightly smaller, but if you used the advertised dimensions you'd have a small amount of wiggle room to let the battery breathe a bit. However, the height does NOT account for the battery posts. with the posts installed the height is actually about 9.5 inches, not 8.43. Since it would be rather difficult to use the battery without the posts, please take this into account when sizing your battery space.
All in all, I found this WINGDA 100AH battery to be a solid battery which performed to specs. It is an excellent product and well worth the investment.
