These things look awesome. The digital display is bright, lights do not dim. They are a great size to mount under a seat or with amps and the quality is great as well. Best I could find for price and the value is well worth every penny.

Since the instructions are very veg I had to look on line for videos on how to do it without killing myself. I got it done and it works great ðŸ‘

Haven't tried it yet. But no Allen to put the mounting tabs on.. why didn't the factory do it? The mounting tabs are plastic.. could of used the bottom plate to add mounting tabs..The stinger emblem is cheesy AF. Chrome raised/puffed plastic.. other than that looks solid.. maybe I'll open it and do pics on tok

Just received this popped it open and I'm missing two of the four small screws that attach the mounting tabs to the capacitor. Not impressed. Mounting tabs are cheap plastic, also not impressed. Now this review should have nothing to do with its ability to do its job but if I can't even mount it well, technically it can't do its job. Just disappointed in this day and age have something like this show up and be useless out of the box. All they had to do was make some decent mounting tabs part of the body and also metal and boom 8 less parts to lose.

Up to 1/0 AWG connections, all using the allen wrench recessed connectors, really a plus to have dual connectors for each, easy in and out to equipment.

Does a great job providing reserve power/amp consistency while preserving secondary battery draw when engine is not running. Install instructions are vaugue (treat the fancy diode like a simple one and charging/discharging is easy) we on Vaca for 10 days came back started car turned amps on and 14.2v. This is not an alternative for a Dual Purpose Battery, Big 3, & HO Alternator Upgrade. This is a reserve power boost, if you are having issues with headlights/tail lights/etc dimming... THIS WILL NOT FIX NOR WILL ANY OTHER CAP! Yellow Cap, Mech Man, and 0/1 BIG 3 are your answer... do not trash a solid product operating as it should!

Not very happy with this. The claim is 5 farads. But it won’t keep up with the demand of my Skar Audio RP 1200.1d. Lights still dim. Even with the voltage adjustment on the side at 15.2volts still can’t keep up.
