Review: Works great! - Works great and fits into the tiny location in my car. This battery can not be used as a engine starting battery over about 10 cubic inches, so may work with a scooter or tiny engine. Electric scooters are fine with this battery.
Review: Proud of it - Your battery was a source of doubt for my brother. However, after conducting tests, it has proven to be a powerful battery. Despite paying for 640Wh of energy, I was able to receive 761Wh (as shown in the picture with 11.53V). It is almost 120% energy. It shows 792Wh after charging (as seen in the picture with 14.42V). The size, weight, and energy in such a small package are very impressive. I advise you to purchase this battery and this company. We'll see how great it will be after 6 months of using 100% of its capacity.
