The UC-31 Ioxus UltraCAP is a 12VDC Smart Power ultracapacitor based product for vehicles that improves starting reliability, improves vehicle voltage health, improves battery life, and improves sustainability. With a 15-year design life, you will never change your ultracapacitor again.

Reducing lead-acid battery count in most cases, and reducing maintenance costs associated with low voltage conditions, the ultracapacitor will ensure that your vehicle is ready to start, always. Eliminating thousands of pounds of lead and sulfuric acid from needing to be mined, refined, shipped, and recycled, the ultracapacitor is a major sustainability enhancement for your fleet.

Improved voltage conditions lead to longer-lasting starters, relays, engine control modules, and greatly improved downtime due to prematurely aged components, creating a higher reliability of starting when you need to, every time. With the UC-31, you will reduce the cycling seen by the battery by more than 40% and increase your starter life by 2x.

Using our Smart Power power electronics, the unit supplies nearly all of the cranking current during engine starts. For short stops, such as during a delivery, the ultracapacitor provides the energy to the electrical bus to support ancillary devices until a crank is initiated. The ultracapacitor stores a relatively small amount of energy compared with a battery, but it delivers engine cranking current. This increases the vehicle bus voltage by greater than 2.0V during crank and reduces crank time by more than 20%. It also reduces peak current to the starter by more than 15%. The UC-31 UltraCAP has the only system that provides voltage stabilization to the electrical bus.

The Ioxus UltraCapacitor will turn on automatically when it sees alternator voltage for the first time. The unit will also turn itself off (go into maintenance mode) once one of the terminals are disconnected, after approximately 5 seconds. The Bluetooth app can also be used to turn the unit on (“Run” mode), off (“Maintenance” mode), or a jump start can be initiated using the app without connecting any additional wires.

The jump start mode will initiate a charge sequence, collecting energy from the battery. Once the UC31 capacitor is charged, it will assist the low batteries to provide the power to crank the engine.

The 12V Ioxus UltraCapacitor is designed to work with at least one 12V battery connected in parallel, and the unit needs at least 6V to be able to turn on. Often, when installing the UltraCapacitor, one or more batteries can be removed.

Increased Reliability – prevents stranded vehicles, starts in the harshest of conditions

Increased Efficiency – powers hundreds of Stop/Start events per day, ideal for delivery vehicles

Rapid Payback – Keeps your trucks rolling Battery life doubled Starter life doubled

Built-in, no service call, “Jump Start” – even with a dead battery

10 Minute Installation- direct battery replacement (2 Wire) – No Rewiring!
