COASTA M365 Scooter Battery,36v 7800mAH Rechargeable Electric Scooter Battery Replacement Pack with/Without Communication Interface for Xiaomi 8.5" M365 Scooter Original or Imitation, Extra Adapters

Used two of these batteries to bring two electric skateboards back from the dead, and wow… best thing since sliced bread. They work exactly as advertised, the install was stupid-easy, and everything just clicked like it was meant to be there. One requirement: READ THE INSTRUCTIONS, if for nothing else than the laugh. (Pro tip: break out a magnifier, because the font is basically “ant-sized.”) The english translation is about as great at this page is. Don’t short it, use a 36–42V charger (42V is a full top-off for a 10S pack), and you’re off to the races.

Replaced the battery on my daughter's Skyten S7 scooter. Battery fits, charges to 100% and now the scooter works on all 3 driving modes after replacing the rear tire and fixing the E1 error code (broken throttle control wiring).

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).

I don't usually leave review but this product works! I searched in amazon and there are so many different connector types and I am not confident that I buy the right one. It's a waste of time to read all the description and click on the pictures and make sure I am buying the right item. This item has many connectors and I believe it will fit many different types of e-scooter or even e-bike.

A electric scooter saver

The battery fit perfectly and performed correctly. I'm giving this product only 3 stars because it would not accept a charge. I found the wires (red & black) inputs to the battery were reversed in the connector. So the red output from the charging port was connected to the black battery input. And the black charging output was connected to the red battery input. I simply popped both wires out of the battery connector and switched their positions. Then the battery charged correctly.

I measured the amp hours and I got 7.193ah this equates to .92% efficiency which is reall good. I dont give to many glod reviews but I have to give credit when its due. This battery fits a Hiboy Max V2 scooter perfectly also. Battery cells are not labeled so longevity and quality is unknown.

I’ll give this item 5 stars as it was exactly as described, arrived quickly and seemed well built. I had to return this item as I was hoping it would fit into an Hiboy s2 lite but the scooter was not big enough to house this battery.
