HQRP 100f 2.8V Super Capacitor Compatible with Power Source, Boost Pack, Solar Light Project, DIY Projects, Tax Control Machine, Toys, Electrical Power Equipment, Supercap 100-Farad

I am really surprised I didn't believe it. I can't say whether they're 500 ferrets or not just because I don't know. but I can say I charged the capacitor at 5 amps for about 3 minutes give or take and I've been running this motor for 15 minutes already and it has barely dropped .2 volts. I'm not one to leave good reviews but in this situation I want other makers like me to know this is definitely worth looking into. Plus when they get more in I'm going to order enough to make a 12 volt cell.

The units I purchased only measured ~98 farads. Some current leakage but not terrible.Price is honestly a bit high considering these issues, but you can do worse here.

These capacitors are indeed quite thick. I use 2 in parallel for spotwelding. Out of two supercapacitor sellers I've bought from, these were much better they have low self discharge and can do good medium thickness spotwelds.

I have yet to test this capacitor under very heavy loads but at 10 amp draws it functions as expected.

These capacitors are great. Though it takes a long time to charge, they can weld a bit.

good product ill be using much now on various solar energy projects

I use it as a spot welding machine

Seem to be a good value on testing them
