Maxwell Ultracapacitor / Supercapacitor Module - 16V500F – Audio, Solar, UPS, Battery Assist.

Maxwell Technologies, Inc. was an American company that specialized in the design and manufacture of energy storage and power delivery solutions. In 2019, Maxwell Technologies was acquired by Tesla, Energy Storage and Power Delivery Solutions who sold it to UCAP Power (San Diego-based startup) in July 2021. Ultracapacitors are the technology of choice for high energy/power applications because of their long operating lifetime, low maintenance requirements, and superior cold weather performance when compared to batteries.

Since Ultrcapacitor /Supercapacitors have a much higher rapid charge and discharge capability than batteries they are generally used in parallel to maintain system voltage during high current conditions which greatly extends the life of batteries.

Ultracapacitor are discharged after testing using high wattage resistors. Afterwards a shorting cable is installed for storing and shipping. Ultracapacitors have an unlimited shelf life when stored in a discharged state. Before installing remove the shorting wire. Due to high current capability of Ultracapacitors they should be discharged using a high wattage resistor or alternately using a low voltage/high wattage bulb.  

Note: Do not exceed 2.7 VDC per Ultracapacitor or 16 VDC per 6 Cell Module. Recommend connecting in parallel with batteries of lower voltage to ensure an overvoltage condition is not experienced. 

Cautions: Do Not Reverse Polarity, Do Not Open, Do Not Put into Fire, Improper use May Result in Personal Injury and/or Equipment Damage.
