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.

See specifications below.

Solid!
Style: AVR-X3800H
It's a rock-solid receiver with modern and future-proof features. Denon isn't the flashiest or most aesthetically pleasing design; however, the unit is reliable and sounds great. I used Dirac Live to fine tune the system, and it's been a worthwhile upgrade from my X-2700.

Great replacement to my older 5.1 Yamaha receiver.
Style: 7.2 Receiver
Great replacement for an older Yamaha. My previous unit lasted 10 years and I see no reason why this new one wont last another 10. Familiar features and setup to other Yamaha receivers. Zero issues with setup and contrary to others, you can use all the features without the app. While the app does add some features for streaming, the unit is fully usable as a receiver for movies, surround, etc. without the app. Overall the sound improvement is spectacular, the high slew rate really makes a difference and DSP much improved over the older 10 year old unit I had. Solid hardware, solid setup and while I'm not about Brand Loyalty, the Yamaha still had better features, reviews and quality than the other major brands. I would have no issue recommending this to unit to anyone. Remember, these units are about the sound they offer, not the the wiz bang features you see in some other units. Reliable hardware, reliable sound and a rich feature set makes this unit a no brainer.

Great receiver for money!
Style: 7.2 Receiver
I got this to replace my lackluster Onkyo TX-NR6050 I purchased from Costco. Three areas stand out for me with the Yamaha receiver: 1: Audio, movies sound great, dialogue is clear. Action scenes are impactful and dynamic. 2: Picture quality, bright, vibrant and beautiful colors from my PC and from my Firestick. 3: Ease of use, out of the box ready to go. Menu is dated (no gui really just an overlay, which is fine by me). Renaming inputs, adjusting speaker settings and setting EQ preferences super easy. Took about 20-25 minutes to fully setup. In those 20-25 minutes I was already way ahead of the Onkyo. Great value for the price! Volume is very easy to set! Still have to test PS5 performance, Bluetooth connectivity, USB settings, WiFi and a few other items. I’ll probably end up buying a Blu-ray player since this was so easy to setup! Or maybe use my PS5/Xbox One :)
