Anyone know of what sort of money/ other advice it would be for a set of NiCad batteries, linked to a combined voltage of 120v, to power an electric car? Random question of the morning I know!

It will depend on amperage. NiCad's are 1.2v so you'd need 100 to get 120v. Take for example www.ebay.co.uk/itm/Yuasa-Battery-Ni-Cad-1-x-D-Cell-with-Tags-1DH4-OT-/251277758237?pt=UK_ConsumerElectronics_Batteries_SM&hash=item3a81524f1d- They are 4ah so to create a 120v / 4ah battery pack would costs £5.49 x 100 = £549. That would mean you'd have 120v x 4 ah = 480watts for one hour. Of course that isn't anywhere near enough to run a car so the power you'd require is going to be more like 40ah+ and therefore cost rises accordingly to £5490. A 12v SLA battery of 40ah is, say, £150 so the ten needed for 120v would be £150 x 10 = £1500 - saving of nearly £4000 compared to NiCad's. This is purely maths to give you an idea why NiCad's aren't commonly used in electric cars and SLA still rule. Real world calculations might be better or worse. What about finding a scrapped Prius and salvaging the Lithium batteries ? This is an excellent web site to see what other people have done - www.evalbum.com/Paul h |

Theres a reason all the taxi/ private hire drivers in London get rid of the prius's at 4 years old, its because the batteries cost so much to replace you may as well buy a new car!
