I personally own one of these and have observed a 40% degradation in usable capacity since June, 2018. Additionally, they have horribly inconsistent internal resistance (IR) due to shoddy construction.
Under heavy throttle, my car surges. I can watch the current surge from peak to mid-level 1-2 times per second because the high IR block voltage drops like a rock, and the car adjusts.
They are Chinese junk.
Prior to this, I had a hammered reconditioned piece of junk in my car (multiple modules were barely 50% rated capacity). It actually performed a little better due to the consistent IR.
$350 more for genuine Toyota/Panasonic is an infinitely better value.
