WHAT PEOPLE ARE SAYING
"After changing my car's battery to Ohmmu, my phantom drain has dramatically reduced. Never (not even when I recently changed to a new Tesla OEM 12V battery) did I lose so little power after leaving my car parked for a long time."
MODEL X OWNER
Bangkok, Thailand
"I've still never seen it! That's a good thing. Just checked my phone, we are sitting at 174,000 miles now, so 54 months, 164k miles - pretty impressive!"
MODEL S OWNER
"[Ohmmu] battery arrived and is installed! I was only expecting a slight difference in sound quality... but it is HUGE. Makes a really big difference!"
