Basically, this is how I keep my battery in good health. How I maintain and keep everything is top condition despite my excessive use of my vehicle. Example, at 21,000 miles, I still have 207-209 Rated miles on 100% charge on my 60kW pack. When my car was delivered new 7 months 3 weeks 3 hrs and 46 minutes ago, my rated range was also 209 miles. ENJOY! Some useful information I found: http://mpoweruk.com/balancing.htm Information on the Balancing Battery packs, not Tesla related, but a good read. http://www.icharger.co.nz/articles/ArticleId/6/Introduction-To-Lipo-Batteries.aspx Some more good info, based on RC Cars, but still have lithium batteries with multiple cells that need balancing and equalization. http://www.automotive-eetimes.com/en/large-li-ion-battery-packs-active-balancing-improves-many-parameters-part-1.html?cmp_id=71&news_id=222901215 I recommend EVERYONE READ THIS ONE!!! EVEN HAS DIAGRAMS! VERY IMPORTANT! If the Mods agree, I'd like to see this sticky'd, at least the last link.
