Antigravity Batteries Weight Reduction - Audi S4

Today, I upgraded my S4 replacing the weak stock battery with a lightweight lithium solution from Antigravity. My car is heavily modified and I wanted da bit of a weight reduction. A light weight battery made sense more than removing the rear seats to reduce weight. Although the battery swap was straightforward, the car required adaptation coding to recognize the new battery, a process I performed using VCDS, as shown in the video.

I noticed that although there was a Lithium technology option in the adaptation coding, however it caused static current drain codes and dash errors. This could be because the car's battery management is not compatible with Antigravity's battery management. It's best to use the stock "Fleece" option (AGM), which is also the correct one to use for OEM battery replacements, rather than "Binary-AGM."

One of the advantages of this battery is the smart features it offers, such as the integrated BMS, which enables the lithium battery to be managed and accepted by a wide range of cars without wearing it out. The BMS system also provides protection against over-charge, over-discharge, and short-circuiting while maximizing battery life. Furthermore, Antigravity batteries can last from 7 to 9 years. Another great feature is the remote start, which saves the inconvenience of waiting for a charger or looking for jumper cables when dealing with a dead battery. The wireless keyfobs are also a nice touch, especially for a trunk-mounted battery like the one in my S4s. I wonder how to even open the trunk with a totally dead battery.
