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

have order two batches all looks good. It took a while to reach but I am happy!

Excellent product at a very good price. We are using these to power model airplanes with small coreless electric motors. The energy storage capacity is amazing. We are charging to 2.8 volts and running a 720 coreless motor with 65mm propeller (both also from Banggood) for up to about a minute! At this price I can build them into the models permanently and just get more when I build another.I plan to experiment with hooking up 2 in parallel to run a slightly larger motor in a slightly larger airplane.

Using these to power free flight model airplanes "capacitor planes" with small coreless brushed motors. Will buy again.
