Reply To: Using capacitors instead of a battery

[MrEnergy]

Many companies are working on hybrid Lithium-Polymer-Ultracapacitor battery designs looking for the best of both worlds. The benefits of such a battery are high current capability, no “memory”, fast charging, temperature stability, very long life. Prices are high right now for all LiPo types but are coming down rapidly.

There is a way to build your own supercapacitors. My initial design shows a room sized bank of 4’x8’X8′ homebuilt supercaps in order to replace 12 L-16 Trojans. Self discharge rates are unknown until they are built, but they would be very fast charge/discharge capable and would have a very long life. Somewhere on the order of 50 years. These use large sheets of 1 micron carbon with mylar separators.
