Great battery with honest capacity
The review is for the variant with the pink INR18650-26E cells, probably made by DMEGC. These are good cells that actually have the rated capacity of the battery (3x2.6Ah=7.8Ah), and pretty low resistance. And the results? In my case 80% more range than on the stock Jetech battery that was also supposed to have 7.8Ah but was definitely no more than 6.5Ah because it took 6.5 hours to charge on a 1A charger. With the new battery I get 13.4 miles of range riding at 18mph, about 100kg person, with lightly sloped terrain, and before I got 7.25 miles. Why so much better? Capacity is one thing, but internal resistance also plays a big role, because it causes voltage drop under load. So the old battery would reach the minimum voltage while still theoretically having some state of charge left. So if you have a generic m365-like scooter I highly recommend this battery, because it will be a big upgrade even if the original battery says it's 7.8Ah but you are getting suspiciously low range from it. But this one has mounting ears that make it longer, so you may have to push the cables in the scooter around a bit to squeeze it in, depending on your particular scooter. And be sure to double-check the polarity of both charging and discharging cable, especially when using one of the included adapters (one allows you to flip the polarity of the charging cable, which was useful in my case).
