Re: Converting to Lithium
I went the way Sportcoupe did it. I used the Nissan Leaf hybrid batteries ($550 for a 36v 60AH pack). Bottom balanced the pack and use a Quickcharge on board charger (about $250) they configured for lithium batteries that won't overcharge the batteries. Installed a volt meter so I don't over discharge the batteries. I bought a mini-bms system but couldn't get it to work right and have had no issues with the lithiums, just have to be careful not to overcharge.
Increase in acceleration is unbelievable. The Leaf Battery Pack weighs 40 pounds so I lost about 400lbs in weight, that coupled with the lower internal resistance of the lithium batteries lets me spin my rear tires even though I have a high speed gear in the rear end.
