EMC scooter batteries

Mal, do post up your test results when ready. A low peukert hopefully comes with an increased cycle life. This would make lead acid even more tempting for the budget concious. Please consider and describe your charging profile. FYI Have a look at.... http://www.commutercars.com/downloads/batteryChar...

GAIA batteries, new to me

speculators !! If you invest in lithium you are taking the REAL RISK. This applies to investing in beach sand as well.... as we may end up going with Zebra batteries. Be aware that even the best chemical batteries are still falling well short of the public expectation for EVs and maybe always will. ...

Automatic or manual

Rob sums it up well. It is all about your expectations ! Can I add the factor of vehicle range .... Even the best gearbox will only be 85% efficient in top gear due to the helically cut gears. And may be as low as 65% in first gear. This means that your EV may do 85km rather than 100km. This is a bi...

Sorry to harp on about biofuels. The TRUTH is they are NOT green. The main reason is that they are used in the low efficiency internal combustion engine (20%)! They still produce the same emissions with CO2 even though you can argue there is recycling of this. But hey, Kyoto calls for a reduction, n...
