With its 15.6kwh lead acid pack I can get 40 miles on a charge. I've moved to New Jersey and sold off my other, gas powered DeLorean. I would really to bring eD to car shows but I figure I need a 100 mile range to make it effective.
Forty kwh of Tesla battery modules, a BMS and new charger will cost over $10,000. I don't need 1000 battery amps anymore. I won't be doing any drag racing. Are there any less expensive 40kwh lithium batteries that can fit in a 28" x 28" x 13" space? I can get a used EV for $10k. Is it worth switching to lithium? Thank you, David Delman ] %I gleaned the text from Cor's ms-office html post on the above topic% : http://electric-vehicle-discussion-list.413529.n4.nabble.com/Is-it-worth-it-tp4696207p4696218.html I converted my truck from lead acid to 2 used Leaf packs, with the Leaf BMS attached to each. Only needs 12v, completely stand alone balancing. Only drawback is the need to stay with the Leaf pack division: either 320-395v or split the pack at the center disconnect and get 160-198v with no other change than parallel wiring the halves instead of connecting them (in series) to the service disconnect. Each used pack was about 75% of original capacity (24kWh) so I carried a usable ~35kWh but have always taken it safe, never driving more than around 80 miles to a charge which would leave more than ¼ charge available when driving 55 MPH on the freeway for those 80 miles. Cost for the used Leaf packs was below $2k each back then, but I re-configured the packs into stacks that filled up the two halves of my battery box on each side of the drive shaft, sliding 3 small stacks of 4 modules under the cab and having 4 large stacks of 9 modules for the total combined 48 modules (96 cells) on each side, plus the BMS. Most of the work was cutting bus bars and re-routing the BMS wiring, but it all worked on the first attempt (I did double check the wiring though, before plugging into the BMS) Cold weather does not affect the range much, because I have no heater (California and a winter coat when needed) Regards, Cor. - For EVLN EV-newswire posts use: http://www.evdl.org/archive/ {brucedp.neocities.org} -- Sent from: http://electric-vehicle-discussion-list.413529.n4.nabble.com/ _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/index.html INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
