My friend has bought a Tesla electric car. Basically its a Lotus Elise Exige but battery powered. 12K worth of lap top batteries in it so he says. 0-60 in sub 6 secs with a great range. Electric looks like its the way forward

They look like 100AH Thunderskys. Call it 32*3.4Kg = 108.8Kg Depending on driving this might add up to 20WH/mile consumption. Less the lead under your seat. How much heavier. Will you need to double up on motors? 3.2V*100AH*32of = 10.24KWH. Enough for a car. Ideal for strapping to the sides of the etrike. say 100WH/mile into 10KWH = ~100 miles. A lot more if cruising/coasting to stops and more still if the trike is faired to remove air resistance then 200 miles could be expected. The downside with these cells is they must be kept within the sweet spot between the charge and discharge knee's with an intelligent charger that does not allow overcharging. And good cheap low tech means to show if a cell has dropped low is to use lee Harts Batt bridge passive circuit. I've bought the plans! Will have to start a thread about sourcing certain parts because I'm having no luck  |
