Very good price, free shipping and amazing 2 week delivery to eastern USA. Well done, Banggood! I'm using them along with small DC motors to power very small free flight model airplanes. You can see them fly on the sonex413 channel on YouTube. I would like to see other small size supercapacitors available on Banggood, perhaps 7F, 15F, 20F. Thank You Banggood.
Quality is OK, but not great. I looses charge rather quickly. In same LOT, there is noticable variance in performance. I charged all 10 to 2.6V, then, periodically, I measured its voltage: Voltage after 3 hours: 1.7 2.2 1.7 1.7 1.7 1.7 1.7 1.7 1.9 2.2 Voltage after 6 hours: 1.7 2.1 1.6 1.7 1.7 1.6 1.6 1.6 1.9 2.2 Voltage after 13 hours: 1.7 2.1 1.5 1.6 1.5 1.5 1.5 1.5 1.7 2.2 Voltage after 24 hours: 1.5 2.0 1.5 1.5 1.5 1.4 1.4 1.4 1.7 2.1 Voltage after 48 hours: 1.5 1.9 1.4 1.4 1.4 1.4 1.4 1.3 1.6 2.0
