I received the 46135 25Ah cells which took about a month in transit and cost $12/cell. Initial discharge of 0.2C (5A) confirmed the 25 Ah capacity, which is about 77Wh.
Fortunately I read a review from another customer prior to testing the other 3 cells and it described receiving 4 cells that all had the polarity mislabeled. I checked the remaining 3 cells and found 1 to be mislabeled. I'd have destroyed equipment if I hadn't read that review.
I'm excited to build a battery with these larger format cells and try them in various vehicles, especially the motorcycle. Having mounting studs and bus bars will make connecting them much more simple than welding thin nickel strips.
Unless I can find a BMS that can output 200A, I'm not going to bother with it. I'll throw on a cheap balance circuit and call it good, being careful not to discharge too deeply. I'm sure a brief ~8C spike in current to start a car will not cause them any harm.
I might try an EC8 connector and 8AWG wire.
This front cell is mislabeled
