A 5kwh pack is a 5kwh pack. >From Cedric's home at Potters Bar in Hertfordshire, to Honiton in Devon (where his motor design was then built by Lemco), is roughly 170 miles. Cedric was able to complete that journey at an average of about 45mph on a single charge. Top speed is around 70mph. The battery at that time was 48v of 100Ah Thundersky cells. They're now around 10 years old and their internal resistance is now too high for vehicle use, even though they retain much of their capacity. Cedric has a couple of PV panels on the roof of his shed to charge that original pack, plus a few more old cells. The stationary pack voltage is designed so he can just connect his streamliner pack in parallel to charge. He harvests enough energy, pretty much year round, for his commute to Bicester in Oxfordhire where he now works for Agility Saietta (who are partners with AGNI, who now make Cedric's motors). > 300km on a 5kwh pack is 27wh/mile (2.2hp). Enough power for Cedric's machine to do 60+ mph. -- Paul Compton www.morini-mania.co.uk www.paulcompton.co.uk (YouTube channel) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
