Maxwell Boostcap Supercapacitors / Ultracapacitors 48.6V 165F battery BCAP USED
Maxwell Boostcap 48V 165F This is used & sold as is It is comprised of 18 individual BCAP3000 Ultracapacitors, in series, each is 2.7V, and 3000 farads The pictures show a complete "battery" and also a dissected capacitor battery. The unit has a series of charge balancing chip boards. It is comprised of 18 individual BCAP3000 Ultracapacitors, in series, each is 2.7V, and 3000 farads Shipping will be $100. for priority mail. Sorry it will not fit in a flat rate box. you can arrange for palletized shipping from your end for bulk shipping. We can box multiples together. I have more than one available. FAQ1. A single capacitor is 1400F/2.5V or 2300F/2.5V. Why 6 connected capacitors become 233F/15V or 383F/15V? The formula for the series capacitance is as followings: N serial caps 1 / CT = 1 /C1+ 1 / C2 +……， Here is the result for 6 connected capacitors: 6 capacitors of 1400F/2.5V in series connection C=1/(1/1400+1/1400+1/1400+1/ V=2.5V*6=15v 6 capacitors of 2300F/2.5V in series connection C=1/(1/2300+1/2300+1/2300+1/ V=2.5V*6=15V 6 capacitors of 2000F/2.3V in series connection C=1/(1/2000+1/2000+1/2000+1/ V=2.3V*6=13.8V 6 capacitors of 3200F/2.3V in series connection C=1/(1/3200+1/3200+1/3200+1/ V=2.3V*6=13.8V 2、What is the capacitor life time? It can be more than 10 million times of charging/ discharging. The capacitor can be charged/discharged more than 20 times a day for 136 years of continuous usage. It is 1000 - 2000 times of Li-Ion/Ni-MH/ Ni-Cd batteries. 3. Why the capacitor drop the voltage even I don't connect to any device? The capacitor will drain or loss power faster than the regular Ni-Cd battery even not connected to any devices. Some of the capacitor even drop more than 3 voltage overnight. We recommend to connect the capacitors with battery to reduce the voltage loss. 4. How to get to full capacity of the capacitors? This is call the "seat effect" for the capacitors. You need to charge and discharge the capacitors for few cycles to reach its full capacity when you begin to use in the devices. 5. Which model of the capacitors fits my need? Our product is designed of the 12V car system. When place the capacitors in the car, please make sure you have enough space to put in there.
