It's time to upgrade your 2022 (up to March) - 2020 Tesla Model Y 12V battery with a replacement, ultra-lightweight, bluetooth-enabled and performance 12V lithium battery!

Weighing in at only 8.5 lbs versus Model Y's super-heavy 20 lb lead-acid 12V battery, Ohmmu's 12V lithium battery is the battery that Tesla should have shipped from the factory!
