The "perfect" battery cell for DIY e-foil (2025)

The 50s can according to Samsung push quite a lot of current, but those numbers are known to be a bit inflated. The cell will get very hot and the voltage will drop a lot. And it will degrade faster. (Fewer charge cycles)

On a semi-high P count i think it will be “perfect”.

You are correct about your photo. Maybe they were testing with the p50b and then went to the 50s for production.

I generally use the cheapest Lishen elements in the 11s 3p configuration. And when discharged to 3 volts, the battery does not heat up noticeably. By the way, what about the fact that Molicell greatly overstates the capacity? And the capacity of the P50b, measured in tests, is only 4600 mAh. Unlike Chinese tubless, the measured capacity of which coincides with the declared one.

I think there was a mention in a video of them using the “best cells available”. Similar to this thread - “the best cell” for a company selling a product also includes the price. People seem stoked on it with more run time, though I wonder how it they will hold up long term. With normal use 300 cycles will be out of the year warranty period.

I wonder if anyone has done any research on how many cycles it takes a cheap BMS with 80mA balancing currents to destroy a battery with expensive Molicell cells?
