Ultracapacitor Engine Start Boost Module Kit

You are bidding on an engine starting booster module. It consists of seven 2600 farad 2.5 volt Maxwell ultracapacitors connected in series plus a cell balancing circuit to keep the voltages on the individual cells balanced.
The balancer contains seven super efficiency LEDs which give a visual indication of each cell's state of charge. The brighter the LED, the higher the state of charge. Under normal circumstances, they will be quite dim. The current drain of the balancer is under 1 milliamp (.001 amps), very much less than the drains due to the car computer, radio standby circuit, etc, so it can be left permanently connected without causing any problems.
How it Works:

The ultracapacitor bank module is connected across the battery wires, preferably as close as possible to the starter motor. Even if the battery is weak, it keeps the ultracaps charged to the battery voltage. When the starter is engaged, the energy in the ultracaps drives the starter, giving full voltage to the starter, due to its extremely low resistance. This is especially effective in starting diesel engines, as they will not start unless they reach a minimum starting RPM. A weak battery may be able to turn it over, but if it doesn't reach minimum RPM, the engine won't start.
If the engine doesn't start on the first try, in a minute or so the battery will recharge the ultracaps for another strong shot. It is also a very good thing for use in marine applications, as a weak battery at sea can ruin a good day pretty completely.
As a side benefit, the ultracapacitor bank will stabilize the system voltage, which will improve performance of some accessories, such as high power audio systems.

You can think of the boost module as just another battery, but one that will give many times the power of a normal battery for short bursts, is not affected by high or low temperatures, and will never wear out.

To see a video we made of this booster in action, click HERE . This is a 7 liter marine diesel engine being started with only this booster charged off a car battery.

Maxwell has just introduced a nearly identical ultracapacitor starter booster for heavy trucks, so that they won't have to keep their engines running while parked overnight to be sure they can restart in the morning. Details are still sketchy, but it appears the OEM price will be $1300 each!

You will need a sufficient length of heavy cable to connect the module to the starter motor. The closer it is to the starter, the better, but in some cases there is no convenient nearby space, so you will have to figure out the best location. The heavier the cable, the better. Welding cable is a good choice as it is heavy and flexible. You will need to put terminals on the cable ends to connect them to the module, and (depending on your installation) to the starter and ground. When you are ready to connect it for the first time, you might want to connect a headlamp or similar in series with the booster to limit the charging current. After a couple of minutes the headlight will get dimmer as the booster charges. Then you can remove the headlight and make permanent connections. You can skip the headlamp and connect the cables directly, but there will be a good spark and very high current out of the battery as the booster charges.
If you have a high power audio system, you can also run heavy gauge cable from this booster to the power terminals of your amp to get clean audio at high power. The capacitance of this booster is 370 farads, which is 10 times or more the capacitance of supercapacitors sold for car audio applications, so you will be amazed at the difference.
You can install the module in some kind of enclosure if desired.
As a point of interest, the last two photos show a portable booster I made with an old test equipment case and the sealed 12V battery from an old UPS. I put the booster in the case and put the battery in parallel with the booster. If the booster won't start the engine on the first try, the battery will recharge it in about 2 minutes. I also added a small meter to show the booster voltage. This is for a friend who has a good collection of heavy diesel road equipment that doesn't get much use. He put an Anderson connector on each engine, so now when he wants to use a machine, he just carries the booster to the machine and plugs it in and off he goes. You can get Anderson connectors on Ebay at a surprisingly good price. You could also probably use the case from one of the “battery boosters” that are sold to keep in the trunk of your car, but which don't really work well.
This module is fully assembled and tested and works fine.Sold with a 10 day no DOA warranty.  The caps as replacements will be available as long as they last. 
The list price of these ultracaps is over $80 each!
