Miles ★★★★★

Installed it last weekend and the higher usable capacity is already noticeable—the car's systems feel more stable, especially with Sentry Mode running all night. Huge upgrade from the old lead-acid.

Julian L. ★★★★★

I noticed the weight difference as soon as I lifted it out of the box—makes the frunk a bit easier to work in. The eco-friendly angle was a nice bonus, but what really impressed me is how much faster my car wakes up from deep sleep now. Definitely a solid upgrade for any Model 3 owner.

Stella ★★★★★

The usable capacity bump is the real win here—I can actually run the cabin heater for a while before the car complains, which is something the old lead-acid never managed. Plus, it charges up noticeably quicker when the car’s awake, so I don’t worry about it draining overnight anymore. Eco-friendly
