I have been researching various replacement batteries for the Model 3 that had the AtlasBX MF 85B24LS (MF51-650). It appears the factory AtlasBX, while very powerful starting amps (625 CCA) is just a lead acid flooded battery that is maintenance free. It seems like Tesla just put the strongest Lead acid starting battery they could find. But the Tesla's don't need a heavy load of cranking amps but available amperage over the variable charge status of the battery. This may explain why Tesla went with Lion as the new battery installs. Unfortunately the Tesla Lion has different connectors and isn't set up for a retrofit.
It looks like batteries with a BCI of 51R are suitable for size as a replacement. It also seems an EFB or AGM battery would be suitable than the factory MF battery since they are designed for frequent deeper charge cycles.
I know right now the Ohmmu Lion is going through a design change and worked quite well until now, but has anyone tried an EFB battery? I've seen on a post of a user with an O'Reilly AGM 51R (51RPLT) and used it for multiple years and over 50K miles and many software updates including more recent with no issues.
So what would be the choice - Factory AtlasBX again, EFB, AGM or wait for the Ohmmu replacement?
