I am not ready to buy anything, so I don't want to waste his time with what are at the moment speculative enquiries, just wondered if anyone else was having similar thoughts.
PS I was thinking (and only thinking due to costs) of 40ah on my other electric moped, which is 48v. Would be funny to try it on a pedal-assist though!
EDIT:
Chis, I am very pleased. And I am not easily impressed as you have probably gathered. It sometimes took a little time to warm up but it's totally sound now the pack is broken in and properly wired up. The range problem for my Sakura is now history and so is the AGONY of lugging around lead-acids, and I have the peace of mind of knowing that I'm dealing with a very reputable dude indeed. Pretty sure that it will last until British roads take their toll, quite likely it will outlast the bike it's in.. my calculations show that it could still be in operation ten years from now!
It's a very nice, very stable pack - the only time it failed was in a bad dream!
34 Watt Hours per mile, or > 700 MPG. What, me, smug?
