My e2008 GOM went kinda mad today, it was warmer than it has been & I also got the battery even warmer at Gridserve Braintree, it was at 25C in the pack when I headed home & I was getting 4.3 m/kW for a while until the battery cooled a bit & the hills of Surrey took their toll & took it back to 4.1 m/kW. Recent weeks I’ve been averaging around 3.7 m/kW, so the GOM was tripping over itself to produce better figures. GOM went completely haywire after descending Reigate Hill, it thought it could do rather more miles than it really could, but you get used to these foibles, after all GOM = Guessometer.
