This Cell Advantage:
1. Long Life- our super capacitors can do 20,000 times or even more.
2. Safe- Until now we didn't have find one explode accident.o
3. Fast Charge & High Efficiency- Our capacitor can be recharged full in 5-20 minutes
4. Wide Temperature- Our capacitor temperature range can do from -30 degree to +60 degree
5. Lower Self Discharge Than Lithim Battery
What's Super Capacitor?
A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor with a capacitance value much higher than other capacitors, but with lower voltage limits, that bridges the gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more charge and discharge cycles than rechargeable batteries.
