I hear you and that is exactly what I did. Dropped in the Ohmmu and kept the OE battery in climate controlled storage, trickle charged to peak capacity and conditioned every 6 months.I’m sure at some point I will and have been both eyeing and toying with the idea of either replacing the OEM with the Ohmmu when I get the indication or pre-emptively striking and replacing it now and keeping the OEM as a backup. OR waiting for the OEM to fail, THEN having Tesla replace it, THEN get the Ohmmu and have the new OEM as a backup. See my dilemma? Lol.
So far no issues but I’m sure they’re coming.Ski
Sitting there as a backup in case of any Ohmmu issues. The other piece of mind item, Ohmmu's good long term warranty.
