Having had the auxiliary battery fail on the i3 I wanted to fit the upgraded 40ah version rather than the standard unreliable 20ah Version.
The standard black EPM 20ah battery S 61 21 7 623 736 is listed at about £70 but the bigger 40ah battery 61 217 635 788 is only about £50. So a no brainer to get the bigger better battery for less money you would think?...
However the battery strap and tray do not seem to accommodate the larger battery and I am told by the dealer that the larger battery is not a UK option however the Etkbmw.com parts site list it and call it a " Warranty " version and BMW in the UK will supply it to part number so presumably it fits a 1 series or something.
Does anyone else have the larger translucent 40ah battery and if so what country are you from?
