This combo kit pairs the D3400 AGM starting battery with an SB500-34 SuperBANK ultracapacitor wired in parallel. LB7, LLY and LBZ Duramax trucks are sensitive to weak cranking voltage, and the SuperBANK addresses it directly: it dumps a burst of current the instant the starter engages, then recharges in seconds, keeping the glow plug controller, FICM and injection electronics on a stable supply. Two sets of 551 I-Bar adaptors are included to convert the M6 terminals on both units for the GM side-post cables these trucks use.

Extreme cranking power, enormous energy reserve and unparalleled durability make the XS Power D3400 the premier AGM battery for many Domestic, Japanese and European vehicles, including Jeep, Chrysler, Bentley, Nissan and more.
The D3400 is perfect for powering your car, and everything in it. Using Absorbent Glass Mat (AGM) technology, it easily delivers all the energy you need for aftermarket accessories like your audio system or other electronics. Its sealed construction keeps it completely safe from spills and moisture on even the roughest ride.
The battery’s low internal resistance allows it to deliver an impressive 1,150 cranking amps, so your engine starts in extreme hot or cold weather. Use the D3400 as your main battery to power your vehicle. With plenty of juice in reserve, it can run your car while it’s powering an audio system up to 2,500 watts. Using the D3400 as a secondary battery, you have a 4,000-watt capacity just waiting to be tapped.

The XS Power SuperBANK is perfect for high-power car audio systems, engine starting systems, and more. Connect in parallel with any lithium or AGM battery to make a customized power pack, delivering the perfect amount of energy on demand so your amps, battery, or engine gets every bit of power they need—whenever they need it.
The SB500 delivers a surge of power to the factory 12-volt battery as it cranks, then rapidly recharges (usually in only a few seconds), ready to use again. The improved and stabilized voltage leads to longer-lasting factory batteries, starters, relays, and engine control modules, improving reliability and lowering the likelihood of costly repairs.
Ultracaps (aka Supercapacitors) also work extraordinarily well in extreme hot or cold. In winter, the Ultracap delivers a much-needed burst of energy to vehicles using a typically slow-cranking AGM battery. Rated to more than a million cycles, the Ultracap is designed to work well in commercial vehicles or “daily drivers”, normally lasting more than a decade.
