Ultracapacitor 350F SixPack Module KitNote: firstphoto kit offering. CAPCITORS NOT INCLUDED
You are offerding on an ultracapacitor battery elimination module kit. It uses six 350 farad 2.7 volt Maxwell ultracapacitors, includesone printed circuit board, six 1N914 diodes, six yellow T1 LEDs, six yellow or blueinsulating stickers, one 2 position high current connector.
The PCB has extra heavy copper plating (4 oz/sq ft) to carry the high currents that this module can deliver. The LEDs and diodes comprise 6 individual balancing sections, one per ultracap.
Assembly is pretty simple. The board silkscreen shows where to place the components. The ends of the 1N914 diodes with the cathode stripes go in the square holes, and the short leads of the LEDs go in the square holes. The ultracaps will only fit in the holes the correct way. The connector goes in its holes with the wire entry holes facing away from the ucaps. You should probably install the LEDs so they stick up 1/2 inch or so to be sure they are far enough away from the hot solder so they won't be damaged. Install the diodes and LEDs first, then with your multimeter set on diode check, verify that they are not backwards or damaged. If you have to remove one of them, it is much easier to do before the ultracaps are installed next to them.
An ordinary electronic soldering iron will not have enough power to make a good solder joint on the ultracaps. The heavy copper pins of the ultracaps and the 4 oz copper of the PCB will pull the heat of such a soldering iron away faster than the soldering iron can supply it, and so the solder and joint will never be able to reach the necessary temperature. You will need a soldering gun or iron of at least 140 watts to be able to make a good joint.NOTE : The center pin of these ultracapacitors is NEGATIVE, not positive.

Here is a writeup on the completed module: Ultracapacitor 350F SixPack Module This module consists of six 350 farad 2.7 volt Maxwell ultracapacitors connected in series and includes a cell balancing circuit to keep the voltages on the individual ultracapacitors balanced.
The balancer section contains six super efficiency yellow LEDs and silicon diodes which leak small amounts of current from any ultracapacitor in the module if it is charged to near its voltage limits. Incidentally, the LEDs give a rough indication of the module state of charge. The brighter the LED, the higher the state of charge. The current drain of the balancer is very low unless the module is near full charge, so the energy loss is negligible in most applications. If the module voltage is not over 12 volts or so there is basically no energy loss even after months of storage. The data sheet gives graphs of the voltage loss over time.
The module is rated to 16.4 volts maximum, so it easily augments or replaces 12V batteries in many applications. Application Examples:Car Audio Systems High performance audio systems often require more power from the battery for brief periods than the battery and associated cabling can deliver. This results in clipping and distortion in the sound output during audio peaks. The module can be connected across the power leads as close as possible to the amplifier to deliver high current for those times when it is necessary, resulting in crisp clean audio output at all times. Battery life extension
Batteries can store large amounts of electrical energy, but are generally not good at delivering the stored energy rapidly. An ultracapacitor module has lower energy storage capacity, but can discharge its stored energy very rapidly and efficiently. Battery life is adversely affected by short discharge bursts, which can rapidly damage the battery electrode structure. If an ultracapacitor module is connected in parallel with a battery, the battery can handle the steady absorption and delivery of electrical energy while the module takes care of the short high power bursts as necessary. This can result in dramatically increased battery and system lifetime.
Solar Powered Electric Gates
12V solar powered electric gates are convenient access controls in remote locations such as agricultural or oil and gas installations. Batteries are commonly used for these applications, but they have limited life and perform poorly in temperature extremes. Often one of these modules can directly replace the battery with no other changes necessary. The -40 to +70 deg C (-40 to +158 deg F) temperature rating ensures trouble free operation in all climates.
Remote Equipment Monitoring
Oil and gas industry remote production installations often require automated monitoring, often solar powered. Such applications monitor the equipment status and periodically transmit wireless status updates. Ultracapacitor modules can often completely replace the lead acid batteries typically used in such applications.
Remote Weather StationsThese weather stations typically report the weather conditions at intervals, using solar panels and batteries for system power. Ultracapacitors can often replace batteries in this application.
Vehicle Battery ReplacementIn small vehicles such as motorcycles, in some cases the battery may be replaced by an ultracapacitor module.
Vehicle Battery Augmentation
In other cases an ultracapacitor module can be placed in parallel with the vehicle battery. This combination has the energy storage capacity of the battery plus the power delivery capability of the ultracapacitors, so a smaller battery plus the ultracapacitor will have the functionality of a much larger battery alone Emergency Backup Power
In an emergency, power to vital systems may be lost. This can be avoided by locating an ultracapacitor bank near the essential equipment to supply the necessary power in the event of a power loss. For example, passenger aircraft emergency exits have ultracapacitor backups in case of an emergency where power to the door mechanism would be otherwise be lost.
- Bus Voltage Stabilization
Large electrical systems can have voltage sags and spikes due to short term power demands from brief loads such motor starting surges. Ultracapacitors placed near critical subsystems can keep such sags and spikes from disrupting subsystem operation.
This module is made with extra heavy (4 oz) copper on a double sided printed circuit board. It has the balancing circuitry included on the board between the six ultracapacitors. The connector is rated at 80 amps continuous, and 750 amps for 1 second. It will accept up to #4 wire. When installing wire in the connector, first turn the screw counterclockwise until the connector is fully open. Look into the wire entry hole so you can see how it operates. Then insert the wire and tighten the screw clockwise until the wire is tightly secured. There is also provision to directly solder a #10 wire into the circuit board, plus provision to connect a wire terminal to the board with a #10 size screw.
The module is intended to be part of larger electronic assemblies, so the circuit board has four mounting screw holes (#10 screw size) and no other enclosure. You will likely want to protect the circuit board from accidental contact with metal conductors. You can mount it in some kind of box or enclosure, or just cover the bottom of the board with a couple of layers of duct tape or similar.
