Can you add a picture of each cell? I didn’t know Sofirn sold a PLB cell. The common PLB cell most are familiar with is the 5750mah. Pictures might help to clear things up.
The Sofirn PLB 5000mah is this one, right?
The High Drain you tested was this one that says 25A on the label?
Even though the older PLB 5750mah (Shockli 5500mah, etc…) was better than this new one (higher continous amps 20 vs 10-15, plus higher capacity) this newer 5000mah is still beating the cells Sofirn uses in their HD version? Man, that’s high praise to PLB. I wish they hadn’t discontinued the older, better cell.
