New killer battery in the town?
« on: April 14, 2018, 08:17:16 pm »
Has anyone heard of this new battery: us18650vc7?

This seems to be the latest, best 18650 for low drain (<8A) applications. In another words, anything but vape.

Has anyone used this one in a design? The numbers are very decent, and the very few actual tests put it to the overall No.1, topping ncr18650ga.

Any ideas how good this is? I want to use some in a project.

The major concerns I have are that I plan to design my product to have user replaceable calls, so I don't have to ship them as hazardous goods. However, the Sony cell is much harder to source than the universally available Panasonic. Also, since Sony Energy has been bought by Murata, will they limit cells leaking to the wild remains unknown. In other words, will that cell keep being around in the future? I don't have to worry about NCR18650GA, but I have no idea when or if the stock of the Sony cell will deplete.

That is hardly a new cell, been around for a few years now. A cell with very similar performance is the Samsung INR18650-35E. Both great cells for high density packs.

According to a few reviews, 35E is more or less on par with MJ1, better than GA, but slightly falls behind VC7.

Well, just got a bad news from a Chinese battery broker. He said the battery is not for sale to smaller OEMs, it is intended for high volume EV and power tool manufacturers, and even the broker can't get his hands on a steady supply of them.
It seems like I need to consider 35E or MJ1.

GA remains the most available and cheapest cell in the 3450/3500mAh arena, but unfortunately it is the lowest performance cell.
